Have to keep restarting cable modem,: What does this mean?

What kind of cable modem do you have and who is your provider? Comcast initially supplied me with a Motorola Surfboard and it kept losing its connection to the internet. I think (but am not sure) that this had to do with its algorithm of sequentially checking a series of additional channels if it got disconnected for even a moment. This process would then take 20 minutes or so before it came back to the original channel that Comcast uses. Turning the modem on and off restored the connection to the internet almost immediately,

The solution was to replace the modem with a different make and model (after the techs came twice to check the connections, etc.; btw: the modem's diagnostics reported that everything was fine with the modem). Everything has worked great since.

I used to have this problem with my cable provider (I used their provided modem) and I had to turn it off and on several times because it stopped working. I bought a linksys cable modem it hasnt hickuped once.

Have you looked at the logs on the cable modem? Which one is it? Most are reachable at http://192.168.100.1/Some have hidden submenus like http://192.168.100.1/moreinfo.html I suffered with a bad connection in the cable that caused hundreds of "T3 timeout" errors, until one of the many techs realized that there was a grounding block and connection on the roof. They had already replaced several other connectors.

It is possible that your DSL provider needs to see the MAC address of the original computer when the modem connects. Check with your DSL help desk, or with your DSL provider forum at
