1. The WAN port IP address cannot be obtained.
If you cannot obtain the IP address of the WAN port after configuring PPPOE dialing, you can enter the management interface ?? System Tools ?? System Log. If you see the following logs:
Figure 1 Password verification failed
As described in the log, "password verification failed" may be caused:
1. Account error:
Make sure that the user name and password are correct. Note that uppercase and lowercase letters, numbers, such as "0" and "o", suffixes such as "@ adsl" and "@ 163" are missing. gd. You can try to enter this account on a single machine to confirm whether the account can be properly dialed or contacted by ISP to confirm the correctness of the account.
2. The ISP is bound to the MAC address of the computer Nic:
Some ISPs bind the physical address (MAC address) of the user's computer Nic to the user when installing the broadband service. Only the bound computer can access the Internet through PPPOE dial-up, no other computer or router can dial
On the router, the solution to this problem is: use a single computer that can dial up to access the Internet to manage the router, enter the router management interface & rarr; network parameters & rarr; MAC address clone, clone the MAC address of the NIC of the bound computer (single-host dial-up computer) to the vro, as shown in figure 2.
Figure 2 clone a MAC address
3. Non-standard PPPoE is used for user access: for example, the star sky fast software or broadband in my world.
In addition to the above password verification failure, you may see the log as shown in figure 3.
Figure 3 request connection establishment timeout
The log shows that the PPPOE dial-up request sent by the vro does not respond. The possible causes include:
1. Physical link failure, including line connection errors, physical port damage, network cable not plugged in, network cable quality problems, MODEM not synchronized successfully, and MODEM failure, check whether the connection is correct (for example, if you forget the wiring). The MODEM line is connected to the WAN port of the router (for example, the MODEM line is mistakenly connected to the LAN port of the router) is the LAN indicator light of the corresponding indicator MODEM and the WAN port indicator light of the router on? Is the DSL lamp of MODEM always on? First, we recommend that you dial a single machine to see if the internet can be accessed normally? If you can, connect the line again. When the physical link is connected normally, try dialing again.
2. The previous abnormal disconnection, such as a sudden power failure to the MODEM or vro during the normal Internet access, is an abnormal disconnection. The client is disconnected, but the server did not find it at this time, if you dial again, it takes several minutes to complete the dial. The waiting time varies depending on the local line status, generally 3-5 minutes. The dialing log after an unusual disconnection may also be shown in figure 4.
Figure 4 failure in proper PPPOE dialing
When the log in Figure 4 is displayed, you only need to set automatic dial-up for the vro. After a period of time, the automatic dial-up is successful.
2. Disconnection during Internet access
If you have already dial up successfully and your computer can access the internet normally, but a disconnection suddenly occurs during the Internet access, log on to the vro management interface. If the log you see is shown in figure 5, the reason is that the front-end line is disconnected, which may be
The network connection interfaces are loose, MODEM faults, and line faults.. When this log appears, check whether your router software is up to date? If not, upgrade first. If yes, check whether the line is connected and restart the MODEM? In other cases, the connection mode is set to on-demand connection, and the default connection mode of our broadband router is on-demand connection. In this mode, if the user under the vro does not have any network applications, the network will be automatically disconnected after a period of time (15 minutes by default, the prompt log is "automatic disconnection due to no data request", but it will not be a sudden disconnection during normal Internet access, it will only wait for a while after no network application, in addition, when there is a new network connection, the router will automatically connect to the network. For the user, the disconnection process is basically invisible. For monthly subscription broadband services, it is recommended to set automatic connection; for other methods, it is recommended to set manual connection.
Figure 5 PPPOE disconnection
Figure 6 On-Demand Connection mode
There is also a disconnection log for "accept PADT, server request to disconnect this connection", as shown in figure 7 (The picture comes from the TP-LINK online help the user's post ). Each system log of a vro consists of a number and content. The front part of the log is the time parameter for running after the vro is started. The unit is second (s ), the time for receiving PADT can be recorded successively as X, and the closest log prior to this log shows the time for successfully obtaining IP addresses as Y, (X-Y)/3600 to determine how long it took to disconnect. Generally, 24 (86400 s) or 48 (172800 s) hours are automatically disconnected, and then the dial-up is automatically performed. In figure 7, the users are, this is because the IP address lease period of the dynamic IP address obtained by the ISP after an account is authenticated for 24 or 48 hours has reached the set time, the original IP address resources will be withdrawn, the re-allocation process is normal. When using a vro, you only need to set the connection mode to "automatic connection.
Figure 7 accept PADT disconnection
If the logs you see are different from those in the above situations or the PPPOE fault cannot be solved through the above instructions, note that the complete system logs of the current vro are saved and contact the technical support staff.
