| Cable modem disconnects?
Hello All 
Without having to get into specific models and such I just wanted to know if anyone else out there experience this issue like me?
Scenario:
My cable modem works fine for hours or maybe even a day and then I loose connectivity to the Net. All the lights start flashing and then nothing else.
Fix:
Pulling out the plug doesn't do anything. I've learned that I have to pull the plug and also disconnect the cable wire. Then I can plug the power back in and while the modem is going through POST, I can then plug in the cable wire.
any ideas of the issue?
THANK YOU IN ADVANCE!!! |

If the modem needs to be disconnected from the cable to boot properly, there is something very wrong - either with your cable line or your modem. Is the cable grounded where it comes into the premises?

| Your downstream power is quite low and the upstream power is somewhat high; it is possible they could fluctuate further during the day. Make sure there is no more than one splitter between where the cable enters the house and the modem's input. Also, make sure all of the connections are tight. If you've done this, and the levels are still marginal, it's time for a tech to come out. |
