Over the past few weeks my internet connection keeps dropping out, sometimes it requires me unplugging the modem and plugging it in again, other times it just comes back on its own. My ISP is Comcast, and the modem is a DPC2100R2.
If I look at the stats of the modem when the connection to the internet is lost they show as:
Receive Power Level
-15 to 12 dBmV (this fluctuates)
Signal to Noise Ratio
Transmit Power Level
Cable Modem Status
I watched it for a couple minutes, and the receive power was fluctuating, but the SnR and transmit power stayed fairly static.
Any idea's what to do? My wireless network (using DD-WRT over 2 routers) works fine through out all of this. So I am fairly certain it's either a modem or ISP issue. Any suggestions on what to try to figure out the problem and get it fixed?
