PPPoE - what is it? How to configure a PPPoE connection

In the world there are many varieties of network communications that operate on the basis of protocols for various purposes and at different levels of efficiency. Consider the main issues associated with the PPPoE protocol: what it is, how it works, and why it was created. To understand the advantages of this technology, it is necessary to study several important points. We begin our acquaintance with a short introduction to the concept of PPPoE.

The essence of this decision

Answering the question: “PPPoE - what is it?”, It should be clarified that we are talking about a special data transfer protocol. The name is an abbreviation that stands for Point-to-Point Protocol over Ethernet, that is, a communication protocol over an Ethernet network on a point-to-point basis. The connection works similar to dial up.

The difference is in operation: the Ethernet network connects PPPoE instead of a dedicated telephone line. It is worth mentioning the strengths of the technology. We emphasize that the PPPoE connection has the advantage of an expanded range of additional features: you can compress data, authenticate, and encrypt information.

However, the MTU requirements are lower (1,492 instead of 1,500 bytes), which sometimes leads to complications when working with firewalls. Another answer to the question: "PPPoE - what is it?" - can be formulated as follows: this is a tunneling protocol. In other words, this technology implements the ability to configure IP or other protocols via PPP or Ethernet connection. Therefore, PPPoE can be used for virtual calls, “point-to-point” connections and sending IP packets, while receiving all the advantages of PPP.

PPPoE connection: what it is and how it works

Making a PPPoE connection is easy. The first task is tuning the antenna. Although it is better to entrust a specialist from technical support: you as a user can only connect the kit to a power source. The access point and the radio antenna are connected with a thick cable, a pair of twisted wires are brought to the computer. The wire is crimped and connected on the one hand to the access point, and on the other - to the network adapter.

PPPoE protocol: what are these and what errors can produce

When working with the PPPoE protocol, various technical errors may occur, for each of which decision algorithms have already been developed. It is worth talking about them in more detail. Consider typical PPPoE errors.

A popular problem is number 633 and means the absence of a modem or its incorrect configuration. To correct the situation, you can restart the computer, try to access the Internet and recreate the connection.

Error number 676 means that the line is busy. You need to log in again on the local network and connect, and after rebooting, uninstall and reinstall the network driver.

If the remote computer does not respond (error 678), then you can check the operation of the antivirus and configure the firewall, if any. Reconnect the AC adapter, check cable operation and contact presence in the connectors. In addition, check the card and reinstall the drivers. Lack of connection with the server is allowed, but this is already a system problem.

In any case, you need to understand the cause of the problem and highlight all the possible sources of problems. You can contact your provider where a support service will advise you. Other common errors: 691 (access denied), 711 (service issue), 720 (inconsistent connection protocols), 52 (network names cannot match)

Numerous internal error numbers of the Windows system (600, 601, 603, 606, 607, 610, 613, 614, 616 and others) are eliminated by rebooting and removing viruses. It is better to undo changes to settings that have recently been made. If there is an incorrect configuration of the internal network configuration, then error 611 occurs. It is necessary to check the functioning of the local connection.

Error 617 may be a symptom of an internal OS problem. Technical support specialists will help you deal with most of the irregularities. The OS has information about malfunctions, their diagnostics are carried out, while the solutions to problems are already embedded in the system.


pppoe errors

PPPoE technology - wireless, transmitting data through the air. A leased line is too expensive, and its implementation is not always physically possible. The modem connection is slow and often fails. The radio connection is more reliable.

Providers are not always ready to provide high speed, which they themselves are cutting back. It is important to adjust the antenna and direct it to the station in order to optimize the signal flow. There is also such a thing as wan miniport PPPoE. What is this you ask? In short, this is another area that a connection error message may refer to. If it occurs, contact technical support.

It is necessary to clarify the protocol features, as there are some advantages to each type of connection. PPPoE transfers PPP protocol frames directly over an Ethernet network. The difference from the traditional IP connection is that there is a need to create an account on the gateway - this is important for establishing control and its simple format. In addition, the process of setting up a function such as billing is facilitated.

The difference between PPPoE is the speed, which reaches 100 megabits per second. The transmission medium is Ethernet. It uses a special technology - the PPP stack, which is not innovative because of its prevalence.


For connection and high-speed connection, WAN Miniport with PPPoE protocol is used. At the time of starting the connection at high speed (especially when using the operating systems Windows 7 and 8), a connection error occurs. This error has a code of 651 and is associated with a communication failure when using ADSL and with the incorrect operation of the router.

To fix the problem, you need to go to the server (for example, and find out if there is a connection to the Internet. The problem may be hidden in the subscriber’s technique (malfunctions in the modem, router, fiber-optic terminal) or may be the problem with providers.

This operation can be carried out by a computer user who has an initial level of training. So, press the "Start" button to call the main OS menu? and go to the "Settings" to determine the type of Internet connection.

From now on, you know more about connecting PPPoE: what it is and how this technology works.
