Help on Tele2, tariffs, questions

Technical information tools are constantly being improved, and manufacturers strive to invest in them as much comfort as possible for the consumer. Nowadays almost all electronic devices have at least one interface for data transfer. Thanks to this, they can be connected to a common local network inside the apartment.

Consider short review its capabilities and tips that will make it easier for the home master to create wired and wireless communication channels, ensure the reliable operation of all home Internet devices.

Assigning a home network

The benefits of combining various electronic devices into a single information system we constantly use, without even noticing it, when:

• looking for information on the Internet from electronic devices;
• watch a movie or TV show on TV via the Internet;
• we print photos directly from a smartphone to a printer;
• in the absence of the owner of the apartment;
• we analyze the events taking place in the apartment in real time using IP cameras;
• or perform other operations.

This incomplete list of opportunities provided by the integration of various devices into a single network can be significantly expanded.

Types of home networks

In practice, two types of information exchange are used:

1. radio channel (wireless connection);
2. special cable (wired Ethernet).

Both types can be used single network, where one equipment works without wires, and the other - by connecting with a cable designed for this purpose.

Each type of communication has its own advantages and disadvantages.

Wireless connection

To transmit information over radio channels inside the house, technologies are used:

• WiFi.

They have different capabilities.

The Bluetooth specification allows wireless radio communication between portable devices that support this type of communication.

The transmission technology is based on the use of radio waves with a non-constant, rapidly changing frequency, which only the transmitter and receiver know.

This ensures both protection against interference arising from the operation of several closely spaced devices, and the security of data transmission.

At home, Bluetooth is most often used to connect a headset, mouse or keyboard to portable devices, less often printers, cameras and other compatible equipment.

Wi-Fi as an alternative to Ethernet

Wi-Fi wireless connection receives in Lately increasing distribution due to the lack of binding to wires.

Almost all modern devices have built-in equipment for using wireless technologies.

The main differences in data transmission via a wired Ethernet connection with Wi-Fi wireless radio channels are summarized in the table.

As can be seen from the table, the distances for signal transmission and data exchange speed over wireless technology are worse. But, the values ​​​​of both characteristics are quite sufficient for indoor operation.

From the point of view of ensuring the security of information transmission, wireless Wi-Fi also has problems. However, protecting your home network is not always of the utmost importance. Therefore, individual users do not even delve into this issue, either out of ignorance, or simply believing that they have nothing to protect.

In general, wireless Wi-Fi is inferior in performance to wired Ethernet, but its convenience and mobility make it widely used among consumer electronic devices.

Wired connection

This method requires more costs for the purchase of additional equipment and cable laying in cable channels, which affects.

It should be taken into account that the wires located near the equipment can be tangled with each other, create a mess, reduce the safety of operation.

True, one original way of transmitting information was invented. It uses the channels of a 220V household electrical network by connecting a PLC modem to it. This technique saves money on cabling. But for a number of reasons, it did not develop.

Access to the Internet in the apartment, private house and office

In home and office networks, a wired network connection is most often used due to Ethernet technology. Providers (organizations involved in customer access to the Internet) usually provide their equipment (router or modem) to subscribers for installation on the premises.

It differs in design and may have:

• a single port (connector for connecting a cable) or several;
• the technical ability to transmit Wi-Fi or be without it;
• additional functions (Internet TV connection, and others).

Thanks to this equipment, the Internet works in our apartment. To provide a Wi-Fi connection to it, it is enough to indicate on the receiving electronic device:

• network name;
• key (password) to access your network.

Both of these parameters are registered in the modem.

For a wired network, most often the equipment parameters are automatically detected and connected (DHCP must be enabled for this). However, in some cases, they may need to be adjusted.

In general, a computer local area network does not have to have access to the Internet. But, given the relatively cheap connection rates and the great opportunities for expanding user functions through access to the World Wide Web at home, such networks are becoming a rarity.

Internet connection technology from provider to subscriber

Organization of dial-up access (Dial-UP)

This is a rather "ancient" connection method that works on telephone networks with outdated coordinate exchanges. Communication via the Internet is created by a modem that dials into the station equipment and switches with it.

The connection speed with such a connection is highly dependent on the quality of the connection and the resulting interference. It rarely exceeds 32-56 Kbps. The telephone line itself is busy and cannot be used for a conversation.

ISDN (Integrated Services Digital Network)

Such a network allows simultaneous transmission of voice and digital data.

Unlike Dial-Up, the phone will not be busy while connecting to the Internet, and its speed will be an order of magnitude higher.

PON (Passive Optical Network)

A gradual replacement of a conventional cable with fiber optics is being carried out, which, despite the increased cost, opens up completely different possibilities.

PON technology allows you to transfer data at high speed from the equipment of a telecommunications company to a subscriber. The quality of the transmitted signal over fiber is an order of magnitude higher than over a conventional cable.

WiMAX

A type of wireless communication capable of transmitting information over distances of several kilometers at high speed. It is provided by telecommunications companies for accessing the Internet to their customers by installing base stations and WiMAX terminal equipment. This technology is gaining popularity.

Satellite Internet

The organization of an access channel via satellite requires:

1. installation specific satellite equipment tuned to the satellite - dish antennas;
2. registration with a provider providing Internet access via the specified satellite.

It is worth noting that there are two options for using the Internet via satellite:

1. asymmetric organization of the communication channel;
2. symmetrical channel.

The first way is cheaper for the user. Outgoing packet requests go on a separate channel. This is a very insignificant traffic and it is enough to use the mobile Internet, which is paid separately.

Reception of the requested data is carried out via a satellite channel. The reception speed and received traffic from the satellite are much higher than for outgoing packets.

The second option is much more expensive. It provides for the exchange of incoming and outgoing traffic directly through the satellite. The undeniable advantage of this type of connection is the ability to organize access to the Internet from anywhere in the world, if the necessary equipment is used.

As a rule, it is used when it is necessary to have access to the Internet and there are no other options for connecting it.

DOCSIS technology or TV cable connection

This type of connection is used by some cable TV operators. The principle of operation of such a scheme is quite simple. A coaxial-type cable brought into apartments to subscribers at the expense of a divider branches into two outputs:

1. one channel works directly on the TV;
2. the second output is connected via a modem using DOCSIS technology(Data Over Cable Service Interface Specifications).

This modem then distributes the Internet to the receiving electronic devices. And in the simplest case, you can generally use a special computer board (TV tuner) that supports this technology.

This method has not become widely used due to significant drawbacks:

• the channel width strongly depends on the number of connected subscribers using the Internet connection;
• low data transfer rate.

However, cable television operators may use this opportunity to provide additional services to their clients.

Mobile Internet

The main advantage of this method is that the Internet is always at hand, but it is limited by the operating network of the operator mobile communications. The connection is implemented through the built-in modem of a mobile device (phone, smartphone, communicator, tablet) or through the operation of a separate USB modem.

Mobile Internet uses one of the types of technologies:

• GPRS,
• edge,

Even despite the low speed of information transfer (GPRS - up to 40 Kbps, EDGE - up to 236 Kbps, 3G - up to 3.6 Mbps, and only 4G - about 100 Mbps), this type of Internet access is used popularity.

The considered list of data transmission methods best suits the interests of home master to provide communication via the Internet. The remaining methods are more suitable for office organizations.

In MTS, the parameters of the “Unlimited Internet for a day” option are being changed, in MegaFon they have “legalized” and expanded the set of BIT Pro options, now you can choose suitable option in the range from 30 to 500 megabytes per day.

Revision of the parameters of "daily" unlimited

Clarification just in case: we are talking it is about daily unlimiteds, when the service is connected, the fee is deducted immediately in full, and the service is turned off in a day. There is also a special service of the “Internet on demand” category, when money for a day of unlimited is debited at the time of the first access to the Internet. There were no connections to the network during the day - there will be no write-offs. Such “Internet on demand” in MTS is called “Unlimited for a day" (30 rubles / day with a limit of 250 MB), in MegaFon - "Non-stop 24" and "Non-stop 24 Pro" for 29 and 150 rubles. with limits of 200 MB and 1.5 GB respectively. These options are alive and well and have not gone away.

In MegaFon, "Unlimited Internet - 24" was sent to the archive on September 17, as an alternative, it is recommended to connect "Non-stop 24". Generally speaking, it is strange that this "Unlimited Internet - 24" for 150 rubles. lasted so long. Whatever it was, there are no restrictions on access speed and traffic volume, and at current high speeds, more than a dozen gigabytes can be downloaded per day.

In MTS " Unlimited Internet for a day ”is closed from October 1, in return they promise something similar, but with action throughout Russia, we read the news. "Unlimited Internet for a day" cost 149 rubles. with a full-speed traffic limit of 1 GB (1024 MB). We do not know the parameters of the new offer, but by analogy with the recently appeared Internet options, we can assume a hard traffic limit (complete blocking instead of slowing down) and a slight price increase. Interesting, did you guess or not?

BITS, BIS and BIT Pro

Megaphone definitely decided to kill everyone, unlimited Internet for phones and smartphones breed like rabbits. On the other hand, a lot - not a little, let them be. Two important points that are strongly recommended to remember and keep in mind:

• The marketing technology of older versions of BITs is well thought out and works effectively. As soon as you hit the speed limit (the daily traffic quota is selected), the system generates an SMS message with a proposal to connect the next, more “generous” version of BIT Pro. The trouble is that the price per day of use indicated in the message is not full, but additional to the price of an already connected option. For example, you receive an offer to connect BIT Pro for 4.9 rubles. and enjoy 80 MB of full speed traffic per day instead of the current 30 MB for just BIT. Not everyone will realize that these 4.9 rubles / day should be added to the already withdrawn 5 rubles / day and the total subscription fee will be 9.9 rubles / day, or almost 300 rubles. per month. Krivovato they made an SMS-offer.
• The first connection of the BIT option is free, each subsequent one during the current month - 100 rubles. The idea is clear and raises no objections: money is debited daily in equal installments (and not in advance a month in advance, as in MTS), so the operator is thus protected from those who want to use telephone unlimited for several days a month. The trouble is that you can abandon the "older" and more expensive versions of BIT Pro only by completely turning off the BIT and turning it on again. Accordingly, with a loss of 100 rubles. during the reconnection process. The problem was solved by setting a 24-hour delay. If the option was reconnected within 24 hours after it was turned off, then 100 rubles. are not filmed. Maybe MegaFon will receive some amount of fraudulent traffic, but the main issue (free transition to a cheaper option) has been resolved. It would also be nice to tell your own support services about this, otherwise they still answer that 100 rubles. for reconnection will be removed in any case.

The anatomy of the "multiplied" BITs in the screenshot above. And that's not all, the list does not include the standard BIT (30 MB of full-speed traffic per day for 150 rubles / month), the unadvertised BIT Social (10 MB of full-speed traffic per day for 87 rubles / month), as well as options for a smartphone BIS class. 'Mysterious' BIT Social rumored to offer SMS to occasional users mobile internet with expenses in the amount of 30-70 rubles. per month.

Unlimits for smartphones are compiled into a separate pdf file, you can download. Almost the most popular question: what is "Unlimited Internet - Russia +" for 5 rubles. per day differs from "Unlimited Internet - Russia" (without a plus) for 10 rubles. per day? The bottom line is that "Russia with a plus" connects to the BIT option, which begins to operate throughout Russia for a total subscription fee of 10 rubles per day (300 rubles per month). And "Russia without a plus" for an additional 10 rubles per day extends the validity of any other unlimited option to the whole of Russia. The full set of MegaFon's existing Internet options can be found, pdf-file 100 KB.

Surely you have noticed that the new BIT options are clearly focused not only on phone owners. And that's right, few smartphones need a daily quota of full-speed traffic of 500 MB. Here you need to clearly understand that the smaller the time quantum, the more profitable the tariff or option for the operator. For example, 30 MB per day is much worse than 900 MB per month. The last software update for my Samsung weighed 196 MB, how many days would I download it? Given that for a month of total traffic in a smartphone on a MegaFon SIM card, I usually get 200-250 megabytes, rarely more.

There is also the other side of the coin. With a strong desire, daily monthly fee deductions allow you to use mobile Internet much more economically. For example, if a backup Internet access channel is required, then it is advisable to keep a special SIM card with a near-zero balance and the BIT Pro option connected. You need the Internet - we throw money for exactly the required number of days and use it. With moderate traffic consumption, it turns out much cheaper than the "daily" options.

So, you have finally concluded an agreement with a new provider, and a cable with a plug has been brought into your apartment - a real window to the world. It remains only to connect it to a computer - and the Internet is at your service. However, if it were enough to insert the plug into the socket, you would not need to read this article.

Consider how to connect the Internet to a computer via cable, in the simplest case. Let's say you have only one computer, and you will use it as a router (if you suddenly need a tablet). Or (alternatively) you're going to later, so turn off the router to make remote access easier.

Let's say your computer has a network card (it doesn't matter if it's separate or built into the motherboard), and you just connected an Ethernet cable to its input. We assume that you are running the most up-to-date Windows 10. Although for correct settings Windows 8 / 8.1 or even 7, these instructions will also work: the principle is the same.

Of course, you can always call the master to do all the right job for you. But experts are not always free. In addition, on your own, you will not only save money on a call, but also learn how to set up the Internet on a computer via a cable. In our world, such knowledge can come in handy at any moment.

Dynamic vs. Statics

Now check with your ISP which connection it offers on your tariff plan: dynamic or static.

When connected dynamically your IP address may change depending on the settings of the provider (and if you intend to subsequently connect to your workplace remotely, this may interfere with you). But manipulations with entering parameters are reduced to a minimum: the provider sets the IP address, subnet mask and the main gateway on its own. In this case, it is enough to insert the cable into the computer and that's it, access to the Internet will appear.

Static connection provides a static IP address assigned to your computer (or router if you choose to connect through one). In this case, you will have to manually enter the IP address, subnet mask and default gateway in the connection settings. Usually all these incomprehensible numbers and letters fit into the access agreement or an annex to it. If necessary, you can clarify them in the technical support service, naming your data.

In some cases, access also requires a login and password (do not confuse Internet access as such with access to a personal account on the provider's website - for personal account data is required).

How the connection is made

Let's consider the procedure step by step.

• Insert the plug of the Ethernet cable brought into the apartment into the appropriate port on the computer. Even if you have never done this before, you will not be able to confuse this type of connector and plug with something.

• Right-click on the Start button and find the section "Control Panel - Network and Internet - Network and Sharing Center". In the left column, select the "change adapter settings" tab. A list of your adapters will appear in the main window (more precisely, in our case, one adapter "Connect via local network"). Use the right-click shortcut again and select Properties.

• A small pop-up window contains a whole column of different rows with properties. Select the line "IP version 4 (TCP / IPv4)" in them. While it is selected, click the Properties button below the list box.

Now our instruction forks. Have you checked with your ISP what IP is provided to you? If not, check right now.

• If dynamic, then trust the automatic selection in the IP address and DNS server settings.
• If it is static, then you will have to enter the values ​​manually. As a rule, you need to specify "IP address", "Subnet mask", "Default gateway" and "DNS server". When you have completed entering the data, press the OK button to save your selection.

Important points:

• If a modem is required for the connection, enter its default address as the IP address; usually it is 192.168.1.1. If the modem has a different IP (which is rare), it is indicated on the bottom of the modem itself or in its instructions.
• Usually the provider provides DNS server information, but sometimes this is omitted. Then you can use generic:

1) Public DNS from Google: 8.8.8.8 or 8.8.4.4 - universal solution, usually suitable for all computers

2) OpenDNS - 208.67.220.220 and 208.67.222.222

3) Yandex DNS with its own anti-virus filter - 77.88.88.88 or 77.88.8.2 - if you trust Yandex's anti-virus policy (although sometimes it may consider a decent site unreliable)

4) Yandex DNS with a filter for pornography and other obscene content - 77.88.8.7 or 77.88.8.3 - although depending on what you actually need from the Internet, hehe.

• To reiterate, if remote access is important to you, make sure your ISP supports you so your IP won't change.

If your ISP offers L2TP access, this may require some additional steps on your part. Typically, the provider provides instructions for setting up this specific type of connection, but it also doesn’t hurt to duplicate it from our side.

So, to set up L2TP, you need to:

1. Go to the section already known to us "Network and Sharing Center" and select the creation of a new connection
2. Unlike the previous options, here you should go to "Connect to the workplace"
3. When the system prompts you to create a new connection, select this item
4. Select "Use my connection"
5. Enter the server address provided by the provider. The option to connect immediately should not be selected. You can assign the name that you like.
6. In the next window, enter the username and password provided to you. Don't forget to check the box "Remember password"
7. Connect now when prompted by the system
8. Go back to "Adapter Properties" (as discussed above) and select the "Security" section
9. In the "VPN Type" drop-down options, select "L2TP IPsec VPN". Below is the line "Data encryption", here you need to select "Optional",
10. Under the "VPN type" line, click the "More options" button
11. Enter this same key in the "Key" field. It must be from your ISP.
12. Everything, you can press “OK” with peace of mind and use the connection.

This instruction works for Windows 7 and newer versions.

Why all these difficulties? - you ask. Such a solution has advantages: for you - increased security of the connection (compared to a conventional LAN), for the provider - simplification of the billing system.

PPPoE setup

Before you set up the Internet on your computer, check with your ISP for the type of access it offers. Access via PPPoE requires not only the correct settings, but also authorization using a login and password. You will need this connection method if you do not use a modem or router, but insert the cable from the provider directly into the connector on the computer, without intermediaries.

To do this, you again go to the "Network Control Center" and choose to create a new connection with it.

In the wizard that starts, you select the first item - "Connect to the Internet" - and click "Next". Then, in the window that appears, you should select "High Speed ​​(with PPPoE)".

There is one final step left. In the final window, you need to come up with a name for the connection and enter the login and password issued by the provider. If several people (for example, family members) use your computer, each under their own account, and you want to give them all access, then check the box "Allow other accounts to use this connection."

Now make sure your internet connection is working. And if so, hello world!

Today we will deal with the issue how to set up internet on a computer or laptop. As a rule, the Internet is configured by an employee of the provider at the moment when you conclude an agreement with him for the provision of services - after all, it is the correct access to the World Wide Web that is an indicator of the performance of this service. However, later when you reinstall Windows or purchase new computer Internet settings can fail, and here we will already face a dilemma - call technical support or do it yourself. In fact, this task is not at all difficult, so by reading this article to the end, you can save money more than once.

The most common type of connection is cable - a wire is pulled into your apartment with a special LAN connector at the end, which is inserted into the network card in the PC case. However, depending on the provider, there are several types of network connection. How to properly set up the Internet and how the connection to the World Wide Web occurs should be indicated in the paperwork of the contract that was given to you when the employee first set up the Internet. There are several of them - automatic IP, static IP, PPPoE, L2TP, filtered by MAC address. Let's consider them in order.

Internet setup automatically

I called this type automatic, because if the provider connects you using this type, then you are lucky - you don’t have to configure anything at all. With it, the computer receives an IP address on the network “by itself” - that is, we simply plug in an Ethernet cable and use the Internet. If it doesn’t work, then make sure that all configurations are reset - to do this, go to “Start> Control Panel> Network and Internet> Network and Sharing Center> Control network connections> Change adapter settings", right-click on "Local Area Connection" and go to "Properties> Internet Protocol version TCP / IP v.4". Here all values ​​​​should be set to "Automatic", as in the picture

Internet connection on a computer with authorization

In this fairly common type, or rather types, because there are two of them, you will have to sweat a little and create a connection with the handles and enter your login and password to set up an Internet connection. If you click on the desktop icon every time to enter the Internet, a connection window opens in which you click on the button - this is your case.

PPPoE

PPPoE - connection to the provider's servers occurs only by login and password. If you suddenly reinstalled Windows, then in order to restore the ability to exit to no, do the following:

1. Go to "Start > Control Panel"

   

2. further in "Networks and the Internet"

   

3. and in the "Network and Sharing Center"

   

4. Here, somewhere on the page (in the left column for Windows 7 or in the main window in Windows 8 and 10) we see the menu item "Set up a connection or network" - click on it

   

5. Here we select "Connect to the Internet" and click "Next"

   

6. Select "High Speed ​​(PPPoE)" and move on

   

7. We enter the login and password that the provider issued - they are usually indicated in the contract.

   

8. After that, we return to the "Network Sharing Center" and find the link "Change adapter settings" in the menu - we go through it.

   

9. We find "High-speed connection" - now it is in the "Disabled" state.

   

10. Double click on it, a window for authorization will open. Click the "Connect" button and enjoy! For convenience, this "High-speed connection" can be dragged with the mouse to the "Desktop", creating an icon with a quick link.

    

L2TP

L2TP is another type of Internet setup with authorization. To activate it, we do everything the same as in the previous method, up to step number 4 inclusive.

Connecting a laptop to the Internet with a static IP

next type it will not ask you to enter your login and password and click on the icons for the connection each time, but it does require you to manually enter the IP address settings to connect to the provider's equipment. For the settings, we go through the chain “Start> Control Panel> Network and Internet> Network and Sharing Center> Manage network connections> Change adapter settings”, right-click on “Local Area Connection” and go to “Properties> Protocol Internet version TCP/IP v.4”.

And enter in the IP address and DNS server fields the values ​​\u200b\u200bthat the provider provided.

Filtering by MAC address

And finally, for any of the above types, the provider can apply filtering by MAC address. This means that you can only connect to the Internet on the computer that is registered with the provider. Insert the cable into another one and the Internet will disappear. This byaka usually appears at the moment when you bought a new computer (or network card), brought it home, but the Internet does not plow. To be honest, I don’t understand at all why some of our “friends” do such garbage, but if this is the case, then you can activate access to the network only by calling the support service and saying that you bought a new PC.

That's all for today - I'm sure that you now know exactly how to connect the Internet to your computer and you can 100% do it yourself!

In our information age, it is difficult to find a person who has not used the Internet at least once in his life. The World Wide Web has enclosed in its "embraces" both large cities and the most remote settlements of our country. Previously, you could only connect to the network using a regular landline phone using a Dial-Up modem. Now the situation has changed dramatically. Let's consider what methods of connecting to the Internet exist, and let's talk in detail about the technical aspects of connecting to the World Wide Web.

Ways to connect to the Internet

Having become the owners of a home computer, after a few days the user begins to think about the possibility of connecting to the worldwide Internet. Ways to do this - a large number. Consider the most common:

Below are the most popular and affordable methods of connecting to the Internet.

Available to everyone: Internet via ADSL modem

Connecting to the Internet via a Dial-Up modem has long supplanted ADSL technology. Let's compare these two, until recently the most popular, connection types:

Mobility first: mobile phone and wireless modem

Owners of laptops to connect to the worldwide network choose mobile phone or wireless modem:

1. GPRS. Packet data transmission is carried out through GSM communication standard. Technology features:

• Speed ​​up to 171.2 Kbps.
• Payment for traffic (received and sent volume) is carried out for each used megabyte.
• The ability to use the Internet, both with a laptop and a smartphone.

1. 3 G and 4G. High-speed network access technologies used in modern wireless modems:

• Speed: 3G up to 3.6 Mbps, 4G starts at 346 Mbps.
• The protection of breaks in data transmission carried out at high speed (railway transport, cars), which was the “Achilles heel” of 1G, has been worked out.
• The prospect in the coming years to achieve transmission speeds up to 1Gb / s.

Mass use and popularity: dedicated channel

Network access when dedicated channel, is by far the most massive and popular. Let's name the main features of this method:

Ways to find information on the Internet

Hundreds of gigabytes appear on the Internet every day new information. There are search engines to find the data you need, like . It is they who around the clock "dig" hundreds of millions of pages, which in turn are located on tens of thousands of servers, and thematically organize information. All major "search engines" allow you to search for data according to the following criteria:

• Keywords. Enter in the search field keywords, characterizing the desired.
• Photo. A photo is loaded in a special field, and search system gives URLs of sites with similar images.
• Video. Being on the video tab, the search engine will display media files that have the entered data in their name.

In the search parameters, you can specify the estimated date of posting the desired material on the network, which significantly improve the quality of the result.

Now, knowing what methods of connecting to the Internet exist, you can weigh everything " behind" And " against» and start looking for a provider of this service - a provider. Apart from specifications, such as the speed of information transfer and the stability of the connection, it is important to choose a solution that is also economically feasible. Thankfully, in major cities Due to the competition of Internet providers, the price for using the service is gradually getting cheaper.

We are sure that the tips given in our review will help you make the right choice.

Video about connection methods and the Internet

In this video, IT technology engineer Artem Babakov will tell you what ways to connect to the global network can be in rural areas:
