Windows XP PPPoE Client Error 678
Windows XP PPPoE Client Error 678
Error 678 is the error code that indicates the remote computer did not respond. This error code is rather difficult to troubleshoot since there can be many things that cause this error. Follow the instructions below to troubleshoot an error 678.
1. Verify that the modem is in sync. The modems sync light (Ready/DSL/Line) should be solid green or solid amber (in the case of a broadmax modem). If the modem is not in sync refer to the check sync knowledge base heading or call into tech support to troubleshoot the problem.
2. Verify that there is a solid Ethernet connection between the computer and the modem. A solid connection is indicated by a green link light (labeled link/enet/LAN). Often the link light will blink when there is Ethernet activity between the modem and the PC. If the link light is not on then unplug both ends of the cable and plug them back in, this will "reseat" the cable. If you are still unable to get a link light call into tech support at 866-491-7221 in order to receive further assistance with this issue.
3. Make sure that there is no router involved. A router will cause this error every time. If you are using a router you do not need to use the windows XP PPPoE client, however you must set the router to PPPoE authentication. This is covered in the router setup knowledge base article.
4. Turn the modem off for 10-15 seconds and t hen turn it back on. When the sync light (Ready/Line/DSL) is solid attempt to reconnect. If your modem does not have a power switch simply unplug the power cable.
5. Ensure that the line is properly filtered. Make sure that all phone devices on the line have ADSL Micro Filters installed on them, make sure that there is no ADSL micro filter on the DSL modem. If all filters are correctly installed and you still receive this error the next step is to isolate the line. Do this by removing all phone devices from the line except for the DSL modem, and then attempt to reconnect.
6. Are there any software firewalls enabled (Zone Alarm, Norton Internet Security, McAfee Personal Firewall)? Firewalls can cause the connection to fail. If you have any software firewalls enabled disable them and attempt to connect again.
7. Recreating the PPPoE "dialer" can solve this error. Go to start>control panel>network connections. In Network connections delete the existing DSL Extreme connection. Now click on "Create a new network connection" located in the upper left hand corner of the network connections window, this will bring up the internet connection wizard. From here you want to select the following options. Connect to the Internet>Configure My connection manually>I am using a broad band internet connection that requires a username and password>enter the name of your ISP (DSL Extreme) and click next>Enter [email protected] and your password and click next>Click finish and attempt to reconnect. If you still receive this error call into the tech support department at 866-491-7221 in order to receive further technical support.
