For the last few days, I've had internet connectivity issues. My cable modem (Time Warner) will lose its connection. I requested a tech, who was then scheduled to come 2 days later. 1 hour before he arrives, it goes back up.

Anyway, later on that day, the internet went down again. Power cycling the modem has never helped at all for the last few days. However, I discovered that if I remove the coaxial cable for 10 seconds, the modem will be able to regain a signal. The signal will last approximately 4 hours before going down again.

So, is this a sign that the cable modem is messed up? Perhaps where the coaxial cable connects to the modem? Power cycling doesn't help. Oh yeah, you can disconnect the coaxial cable at the splitter too, and that'll cause the modem to go back online.

It is most likely that it's the quality of the signal that is to blame. For the best quality on cable, the modem should be connected to the very first splitter right where the cable enters the home. Use RG-6 cable to help prevent degrading the signal any further.
