Comcast Arris Cable/Phone Modem Signal Levels

After intermittent phone problems via our Arris Touchstone digital phone and cable modem, a Comcast technician adjusted the signal levels and checked connectors outside of the house. Now that everything is good again, they look like this:

Go to http://192.168.100.1 to view the RF status.

• Downstream should be around 0 dBmV (currently it's -1 dBmV)
• Upstream should be around 45 dBmV

A few weeks later, there were still too many times when the modem seemed to restart/reboot on its own or otherwise loose connections (most LEDs on its front off). It was replaced with a Thompson RCA DHG536 modem that uses the same http://192.168.100.1 to view its status.
