Modem keeps losing connection

For the last week my modem has been losing it's connection about every 15 to 20 minutes.  Do I need a new modem?  I've rebooted everything several times.  I've unplugged everything.  I have wireless, so I disconnected the router and ran modem straight to the computer but I still have the same issue.

What do the modem's signal stats look like ? Try getting them here; http://192.168.100.1

Please post the *Downstream Power Level*, the *Upstream Power Level*, and the *SNR* (Signal to Noise Ratio) numbers.

That address is the correct one. Be advised that the modem may need to actually be in "sync mode" with the Comcast system (the "Online" light solidly lit) in order to access the user interface.

Strange, the online light is on solid but I am still unable to access the link to get the stats for you.  I've tried typing in the address, and I've tried just clicking on your link.  You think I should place a service call and have someone out to check everything out?

Have you tried powercycling it ?

I hate to sound dumb, but what is powercycling?

Unplug all connecting cables and wait 3-5 minutes. Then re-connect everything and give it the time it needs to re-sync with Comcast. Any difference ? If not, perhaps the modem has a hardware malfunction..

I had the same problem, tried everything, even had comcast reset modem. Later found out   I had a bad telephone causing the problem. Changed phone and everything works fine.
