It is difficult to imagine modern life without the Internet. This is communication, shopping, work and, of course, entertainment. At the same time, few people pay attention to the intricacies of the Internet connection. But there are times when you need to understand it and the functionality of the Internet. Knowing about PPPoE will save you time and hassle. You just need to learn how it works, how it differs from others, how to create or delete a connection, how to calculate an error from the code and fix it.
General PPPoE Concepts
There are many types of digital data transmission based on protocols of all possible levels of complexity, efficiency and purpose. One of the most commonly used is PPPoE. The English abbreviation stands for Point-to-Point Protocol over Ethernet. It can be translated into Russian as a protocol for Internet communication via an Ethernet network on a point-to-point basis. One of them is an access server (Access Concentrator or AC for short), which belongs to the company providing the services, and the other is a PPPoE client, the owner of a laptop, computer or any gadget from which an Internet connection is established. Both process participants are connected using repeaters, switches, modems or other Ethernet devices.
In fact, PPPoE works similarly to dialup (from English - remote access), with the only difference that instead of a telephone (switched) line, the session participants are connected by an Ethernet network.
Benefits of PPPoE connection
This protocol has advanced capabilities and advantages over analogs, such as:
- simplicity and ease of use;
- when transferring information, data is compressed, and this has a positive effect on speed, that is, the process is faster;
- every time you enter the network, the PPPoE protocol performs authentication, which eliminates the possibility of unauthorized access to the system;
- multi-platform protocol;
- high resilience to network failures;
- minimum download percentage;
- PPPoE is one of the cheapest protocols for network access;
- data encryption without loss of bandwidth.
How PPPoE connection works
Since this protocol is established by a point-to-point connection, the PPPoE communication process is divided into two stages:
- Initial connection. Both dots (computer and server) indicate their addresses.
- Session start. After "recognition", the connection is started.
Initial connection
At this stage, a connection is established between the user's device and the server, which belongs to the Internet service provider. It is divided into two more stages:
- Inquiry. The client from its point sends a request to find the provider's server. This signal will be received by all participants in the network, but only the one that supports this service will respond.
- Answer. When the point that sent the request finds the addressee, the second communication peer sends an access packet. But there are a great many participants on the network who support this protocol. Therefore, the computer that sent the request will receive many reply packets. For the connection to be established correctly, the client software selects the required access concentrator and returns a packet with information: provider name, IP address, and so on. If it matches all the requirements and the required services are available, the second stage of the connection begins.
Session establishment
After the described exchange of information, the connection is started directly. It happens using PPP (Application Package). Many, if not all, protocols use PPP.
Table: difference between PPPoE and L2TP
| Characteristic | PPPoE | L2TP |
|---|---|---|
| Definition | A network protocol for transferring information using PPP over an Ethernet connection. | Tunneling protocol for data transmission using IP packets. |
| Reliability | Identification occurs through authentication followed by data encryption. | A secure tunnel connection to the server, but on an unsecured network. |
| Volume | Service packets take up a minimum of traffic, as a result, the speed is much higher. | There is no data compression, so the traffic slows down. |
| Data exchange | There are two parallel connections between client-server points. This offloads the system. One channel transmits data, the other - only service information. Which is also beneficially displayed at speed. | The transmission goes through one channel, respectively, the traffic is additionally loaded with service data. |
| Establishing a Point-to-Point Connection | Installed over Ethernet network. This does not slow down the operation of the Internet and such a connection is always protected, since the user is always being authenticated by his data. | Installed over IP, which leads to line congestion. |
| The influence of external factors on work | It will work correctly with any setting. | Very dependent on the IP network. In case of unstable IP or assignment of the same address to another client, the connection is terminated. |
| Requirements for the connected equipment | Works on any device. | Often, connection is possible only on specific equipment. |
| Customization | Establishing a connection is not difficult, following a simple instruction in a few steps. Having established a connection once, then the connection will occur automatically. | Establishing a connection is easy and takes a few simple steps. On some equipment, you have to enter a username and password every time you log on to the network. |
| Other | DoS attack protection. | One of the best VPN bypass protocols. Some providers may block this protocol. |
High speed connection
It is not difficult even for an inexperienced user to make such a connection. The main thing is to follow simple step-by-step instructions.

Making PPPoE Connection on Ubuntu
You can configure PPPoE in Ubuntu using a utility called pppoeconf. To use it, you need to have superuser access rights. You can run the pppoeconf utility using the sudo command. To do this, you need to go through the following path: "Applications" - "Standard" - "Terminal".
- Enter the sudo pppoeconf command. Sometimes an administrator password may be required. After entering it, press Enter.
Login to "Terminal" and enter the command sudo pppoeconf
Upon completion of the search, a list of detected network devices will be displayed, among which you need to find the one you need and confirm your choice by pressing the "Yes" or Enter button.
Select the desired network and confirm the selection
The PPPoE search will start. If the gadget cannot establish a connection, you need to check the cable to make sure it is connected correctly.
Wait for the server search to end
The next step is to confirm the options: noauth - connect in the future immediately without server authentication, defaultroute - always choose the specified route.
Confirm route and authentication
After that, a notification about the change in the dsl-provider configuration will open. It is advisable to make a backup. If critical errors occur during subsequent work, you can restore the previous version.
Select "Yes" to confirm the configuration changes
In a new window that opens, enter the login provided by the provider and confirm it by pressing the Ok button.

Removing PPPoPE Connection
Sometimes there is a need to delete an already created connection, for example, if it was duplicated by mistake. All three methods described below are suitable for any Windows system.
Removal through the "Control Panel"
We go through the already known path: "Start" - "Control Panel" - "Network and Sharing Center" - "Change adapter settings".
In this menu, you can find and delete an unnecessary connection.
After that, you need to find an unnecessary or unnecessary connection and delete it. To do this, call the context menu with the right mouse button and select the "Delete" line. Naturally, it must be disabled before deleting.
If the Delete icon is grayed out, then you do not have administrator rights. You must first get access to the system folders of the gadget, and then go through the same path.
Removal via "Device Manager"
This method takes place through the device manager, so you need to be very careful not to delete the required physical device. The algorithm is as follows: "Start" - "Computer" - "Properties" - "Device Manager". In the section that opens, you need to find the line "Network adapters" (on some devices this line is called "Network devices") and select the name of the adapter that you want to delete.
Open the context menu with the right mouse button and click Disable.
Deletion through the line "Run"
This method is more difficult, so you need to be sure that you have enough skills and knowledge. "Start" - "Run" - in the line you must enter regedit and click OK. Next, in the Profiles section, select HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ windows NT \ CurrentVersion \ NetworkList \ Profiles. In the right column, you need to select unnecessary registries and delete them.
When finished, restart your device.
Common PPPoE Errors and How to Fix Them
It often happens that the connection does not go as smoothly as we would like it to be. Connection error notifications pop up. Each of them is assigned a code by which you can find out the cause of the occurrence and eliminate it. There are many such errors, but most of them are easy to fix on your own.
Table: PPPoE connection error codes, their causes and solutions
| Error code | Causes of occurrence | Remedies |
|---|---|---|
| 691 |
|
|
| 651 | There is no response from the server. | Wait a while and restart your computer. |
| 678 651 815 | These errors are grouped together. May be caused by a damaged cable, errors with incorrect computer settings or antivirus software. Maybe - through problems with the provider's server. | Check if the cable is connected correctly. Disable antivirus and firewalls; contact your service provider. |
| 619 | The balance has not been replenished. Some providers may also have a problem with this code due to incorrect data entry: login and password. | Top up the balance, check the correctness of the personal data entered. |
| 769 800 | Inactive network connection. | Check network connection. "Start" - "Network Neighborhood" - "Show network connections". If there is no connection (in this case, the network icon is gray), then connect it. |
| 734 | PPPoPE is complete. | Create a new connection. |
| 735 | Incorrect IP address. | In the network settings, check the box "receive network address automatically" or specify the data from the contract. |
Recovering a lost password from the Internet
Authorization to enter the network is performed every time you turn on your computer, laptop or other gadget. This procedure is automatic and fast, if so set on connection. The modem sends a request, the provider asks for a username and password. When the required data is received, a connection is made and a new Internet session begins.
But it happens that the automatic connection did not happen, and the user has forgotten the password.
Password from the contract
The easiest way to recover your password is to find an agreement with the provider, where it is necessarily indicated.
Contacting an Internet Service Provider Service Center
If the agreement is lost, you can contact the service center of the provider, where they will help you recover the lost data. You can contact the company providing the Internet by phone or in person at the office. To recover lost data, you need to be ready to provide some information about yourself: passport data for whom the Internet is registered, login, contract number, etc. In addition, some Internet companies will provide such information only to the person for whom the contract was drawn up or by power of attorney.
In the subscriber's account, if there is access to it, you can only change the password, but it will not work to create a new one. To do this, you must definitely know the old one in order to confirm administrator rights.
Resetting the old password using special settings or programs
You can reset the router settings to factory defaults, and then create a new connection. This often helps.
If the agreement is lost, and there is no way to get to the office yet, you can download special programs that will help you recover your password. But remember that not all programs are equally useful for your gadget. An inexperienced user can harm the computer by doing this. Therefore, this option must be approached carefully, weighing all possible risks. Another problem will be that you have to download it by connecting to a third-party network, since there is no home connection. And you can run such a utility only if you have administrator rights.
For example, the dialupass utility, which is one of the most downloaded for this purpose. It is simple, with an intuitive interface, light in weight, only 0.1 megabytes, free and supported by all Windows operating systems. But it will help to recover only those passwords that were saved on the device. Another obstacle to the normal operation of dialupass may be antivirus that recognizes the utility as malware. Therefore, before installing the program, the antivirus must be disabled.
Network Password Recovery is similar to dialupass and has the same functionality. There are two options: demo and paid. Feature: it does not always show the password the first time, you need to restart it several times.
Also in a similar situation, you can use the BulletsPassView utility, which is suitable for recovering a saved password on Windows 7/8.
Video: working with the dialupass utility
No special knowledge is required for Internet surfing. However, you still need to understand some of the basics. This will help you connect to the network correctly, and if errors do appear, it will be easy to fix them. As a result, you saved nerves, time and money for calling a specialist.
(1500 bytes), which sometimes causes problems with poorly configured firewalls.
It is worth noting that some equipment vendors (Cisco and Juniper, for example) use the term PPPoEoE (PPPoE over Ethernet), meaning PPPoE, which works directly over Ethernet or other IEEE 802.3 networks, as well as PPPoE, which works over Ethernet bridged over. ATM, to distinguish it from PPPoEoA (PPPoE over ATM), which runs on the ATM virtual circuit according to RFC 2684 and SNAP and encapsulates PPPoE. PPPoEoA is not the same as Point-to-Point Protocol over ATM (PPPoA) as it does not use SNAP.
PPPoE works as follows. There is an Ethernet environment, that is, several connected network cards that are addressed with MAC addresses. Ethernet frame headers contain the source address of the frame, the destination address of the frame, and the type of frame. One of the cards is listening to the PPPoE server. The client sends an Ethernet broadcast frame, to which the PPPoE server must respond (the sender of the frame is its own MAC address, the address of the receiver of the frame is FF: FF: FF: FF: FF: FF and the type of the frame is PPPoE Active Discovery Initiation). PPPoE server sends a response to the client (frame sender address - its own MAC address, frame recipient address - client MAC address and frame type - PPPoE Active Discovery Offer). If there are several PPPoE servers on the network, then they all send a response. The client chooses a suitable server and sends it a connection request. The server sends a confirmation to the client with a unique session identifier, all subsequent frames in the session will have this identifier. Thus, a virtual channel is created between the server and the client, which is identified by the session identifier and the MAC addresses of the client and server. Then a PPP connection is established in this channel, and the traffic is already packed into PPP packets.
PPPoE Discovery (PPPoED)
PADI
PADI- PPPoE Active Discovery Initiation.
If a user wants to connect to the Internet via DSL, his machine must first detect an access concentrator (DSL access concentrator or DSL-AC) on the provider side (point of presence (POP)). Communication via Ethernet is only possible via MAC addresses. If the computer does not know the MAC address of the DSL-AC, it sends a PADI packet via Ethernet broadcast (MAC: ff: ff: ff: ff: ff: ff) This PADI packet contains the MAC address of the machine that sent it.
An example PADI package:
Frame 1 (44 bytes on wire, 44 bytes captured) Ethernet II, Src: 00: 50: da: 42: d7: df, Dst: ff: ff: ff: ff: ff: ff PPP-over-Ethernet Discovery Version: 1 Type 1 Code Active Discovery Initiation (PADI) Session ID: 0000 Payload Length: 24 PPPoE Tags Tag: Service-Name Tag: Host-Uniq Binary Data: (16 bytes)
Src.(= source) represents the MAC address of the machine that sent PADI.
Dst.(= destination) is the ethernet broadcast address.
A PADI packet can be received by more than one DSL-AC.
PADO
PADO- PPPoE Active Discovery Offer.
As soon as the user's machine has sent a PADI packet, the DSL-AC responds by sending a PADO packet using the MAC addresses from the PADI. The PADO packet contains the DSL-AC MAC addresses, their names (eg LEIX11-erx for the T-Com DSL-AC concentrator in Leipzig) and the service name. If more than one DSL-AC responded with a PADO packet, the user machine chooses the DSL-AC specific POP using the supplied names or service names.
An example of a PADO package:
Frame 2 (60 bytes on wire, 60 bytes captured) Ethernet II, Src: 00: 0e: 40: 7b: f3: 8a, Dst: 00: 50: da: 42: d7: df PPP-over-Ethernet Discovery Version: 1 Type 1 Code Active Discovery Offer (PADO) Session ID: 0000 Payload Length: 36 PPPoE Tags Tag: Service-Name Tag: AC-Name String Data: IpzbrOOl Tag: Host-Uniq Binary Data: (16 bytes)
AC-Name - String Data represents a string AC name, in this case "Ipzbr001" (Arcor DSL-AC in Leipzig).
Src. represents the MAC address of the DSL-AC.
The DSL-AC MAC address also identifies the manufacturer of the DSL-AC (in this case, Nortel Networks).
PADR
PADR stands for PPPoE Active Discovery Request.
As stated above, the user machine must select a POP (access point) - this is done with a PADR packet that is sent to the MAC address of the selected DSL-AC.
PADS
PADS- PPPoE Active Discovery Session-confirmation.
The PADR packet is confirmed by the hub by forwarding the PADS packet, which also contains the Session ID. The DSL-AC connection for this access point is now fully established.
PADT
PADT- PPPoE Active Discovery Termination.
This packet drops the POP connection. It can be sent either from the user side or from the DSL-AC side.
Scheme advantages
- IP headers in Ethernet media are ignored. That is, the user can assign an IP address to his network card, but this will not lead to a "collapse" of the network (theoretically, when working with a network hub, there should not be a "collapse" and when the user changes the MAC address even to the server address, and during operation with a network switch, it all depends on the switch design).
- Each connection is separate from the others (works in its own channel).
- Settings (IP address, gateway address, DNS server addresses) can be transmitted by the server.
- PPP connection is easily authenticated and calculated (for example, using RADIUS).
- PPP connection can be encrypted. For example, when working with a network hub (when all Ethernet traffic can be seen on each network card), it is very difficult to read someone else's IP traffic.

PPPoE (from the English. Point-to-point protocol over Ethernet) is network protocol over Ethernet PPP frames. It is commonly used by xDSL services. PPPoE provides additional features such as encryption, compression, authentication.
PPPoE- a tunneling protocol that allows you to encapsulate (configure) IP, or other protocols layered on PPP, over Ethernet connections, but with PPP software capabilities. Therefore, this protocol is used to make virtual "calls" to neighboring Ethernet machines, as well as to establish a point-to-point connection used for transporting IP packets that works with PPP capabilities.
This allows traditional PPP-based software to be used to configure connections that will use a packet-oriented network rather than a serial link to create a classic password and login for Internet connections. In addition, on the other side of the connection, an IP address is assigned only when a PPPoE connection is open, making it possible to dynamically reuse IP addresses.
PPPoE works like this: there is an Ethernet environment, that is, the connection of several network cards, addressed by MAC addresses. The headers of Ethernet frames contain the address of the recipient of the frame, the sender of the frame, and the type of the frame itself. One of these cards is listened to by the PPPoE server. The PPPoE server must respond to the Ethernet broadcast frame sent by the client. In turn, the PPPoE server sends a response to the client. If the network contains several PPPoE servers, then each of them sends a response. And then the client needs to choose a suitable server and send him a connection request. Then the server sends a confirmation to the client with a unique session identifier, and all further frames in the session will have this identifier. That is, a virtual channel is created between the client and the server, identified by the identifier of the MAC addresses of the server and client, and the session. After that, a PPP connection is raised in this channel, and IP traffic is packed into PPP packets.
PPPoE is PPP over Ethernet, a protocol that allows PPP frames to be sent directly over Ethernet. The main advantages of PPPoE over traditional IP over Ethernet are that LAN connections require an account on the gateway. Such organization of the local network makes it possible to simplify the control and configuration of billing.
PPPoE protocol is a complete analogue of dialup connection, differing only in speed - up to 100 Mbps, and transmission medium - Ethernet. The Ethernet network uses the PPP stack technology, which cannot be called new, since it is already quite widespread.
PPPoE works on the principle of establishing a point-to-point connection over a common Ethernet environment, therefore, the process of PPPoE operation can be divided into two stages. In the first stage, two devices communicate their addresses to each other and establish an initial connection, in the second stage, a PPP session is started.
Advantages and limitations of this protocol:
1) Convenience and ease of handling.
2) Multiplatform.
3) Simplicity and ease of handling.
5) Compared to VPN, no grinding costs.
PPPoE (Point-to-Point Protocol over Ethernet) is a communication protocol over Ethernet. For ISPs, the main advantage of PPPoE is that they can easily get by with a limited number of IP addresses by simply assigning them to only those users who are currently connected. Also, with PPPoE, ISPs can flexibly manage their customer base, and it will be more difficult for individuals to host FTP and Web sites on their servers.
Compared to other types of broadband services, PPPoE has much higher security, which will undoubtedly be appreciated by consumers. After all, it will be more difficult for hackers to identify and break into computers with temporary IP addresses. Inconvenience to the user can be delivered by frequent error messages that are issued when the authentication server fails from the provider's side. Thus, PPPoE cannot seriously affect the connection speed. In essence, this protocol creates a tunnel connection between the provider and the subscriber.
You need to authorize PPPoE via CHAP, which means that passwords are always transmitted in encrypted form, and the system records the time the subscriber connects to the network, which makes it easy to check if disputes regarding traffic arise.
In modern life, the PPPoE protocol has become an integral part of the provision of Internet access services by a provider based on xDSL technology. This protocol provides additional capabilities, such as encryption and compression of data during transmission, user authentication. This protocol functions in Ethernet networks. In this regard, it is often necessary to purchase a router that supports this protocol. For example - TP-Link pppoe router.
Router connection interfaces
As a rule, such modems on the rear panel have several connectors for connecting network cables. One of them is called WAN (global computer network) - it is in this connector that you need to connect the cable that goes to the telephone socket and then to the provider. The rest of the connectors (power connectors and USB port are not taken into account) have the same appearance and dimensions, but they are grouped separately. They already serve to connect nearby computers and devices, and are called LAN (local area network).
A router can be both wired and a pppoe wifi router - this has no fundamental differences. Wi-Fi is undoubtedly more convenient, but the price for such modems is slightly higher than for wired ones.
Configuring the router. Entering the settings menu
Setting up almost any modern router is traditionally carried out through the web interface. If we take a TP-LINK router as an example, then to configure it, you need to go to any web browser (for example Internet Explorer) and enter 192.168.1.1 in the address bar (this is the standard IP address of all routers set by the manufacturer). Of course, provided that the router is already turned on and connected to the computer. In this case, a window will appear asking you to enter your username and password to access the device settings. If the router has not been previously operated and the factory settings have not changed, then the login and password will be admin and admin, respectively.
Configuring the WAN interface of the router. PPPoE List Selection
Since the topic concerns the PPPoE standard, we will not consider the initial settings, such as changing the password for entering the settings menu, changing the password for connecting to the network, and the like. Let's go straight to configuring the WAN port, which is directly related to the protocol. So, go to the "Network" tab, then in the "WAN" list that appears.
In the upper central part, we will see the "WAN Connection Type" option, by clicking which will expand the list of available connection options. Choose PPPoE.
Configuring the WAN interface of the router. Entering username and password
Having selected the PPPoE item, you will need to enter a name in the "User Name" field, and the password provided by your provider in the "Password" field. In the “Confirm Password” field, re-enter the password in order to avoid an error.
After entering the name and password, just below we select the "Connect Automatically" option, which means to establish a connection automatically. It is advisable to use the rest of the functions of this section if it is necessary to restrict access to the Internet, for example, strictly at certain hours or to disconnect the connection during a long period of non-use of the Internet.
Of course, the appearance or location of the option may differ slightly depending on the router or firmware, but it is always present. Be sure to press the "SAVE" button after making any changes to the router configuration to save our settings. This completes the pppoe router configuration.
When you have to configure a router for your provider, as a rule, difficulties often arise with the choice of the type of connection and the corresponding parameters. If the provider implements for the connection PPPoE protocol, then the problems become much more. In particular, the technology based on the connection using Dynamic IP, much easier to connect: the Internet works immediately after connecting the cable to the WAN connector router.
An error "without access to the Internet" will appear on your devices in case of an incorrectly specified type of connection and other necessary parameters. Mobile devices will not show such an error, but they will not be able to access the Internet.
Another important point: by connecting a network cable to the router, and then from the router to the computer, you will not be able to start a high-speed connection. I described this topic in. In general, the difficulty of getting a high-speed connection up and running is inherent in PPPoE when used by an ISP.
But we don't need high-speed connections on our computer. To do this, we simply use a router, the purpose of which is precisely to connect to the provider and further distribute the Internet to the devices.
I have already touched on the topic of customization PPPoE connections in the article on installing the device TP-LINK TL-WR941ND, but now I want to return to it again, highlighting all the important points in a separate article. After reading it, you will understand how to set up correctly router connection TP-Link by protocol PPPoE... Routers from other companies have a slightly different control panel, but the information will nevertheless be useful anyway.
So you've figured out what your ISP is using PPPoE connection technology... Another important point: ask if you are using binding by MAC address... Only in this case you will be able to easily configure the router without outside help.
The most elementary thing will be to ask the provider's support service what technology they use to connect and specify it in the settings, and also at the same time you need to find out if the binding is made by the MAC address.
Configuring PPPoE connection on Tp-Link routers
In case the provider performs for the connection binding by MAC addresses, you need to clone the MAC address from a computer connected to the Internet. The second option is for the provider to bind the router's MAC address to the MAC address. You can read this article.
In general, then, this is all that I would like to tell you about setting up a PPPoE connection for Tp-Link. The device can be configured in the same way. L2TP and PPTP... I hope you have no questions left on this topic.
