Belkin Play B600 Duplicate IP Address Problem

I have a cable modem internet connection that's shared by several computers at home via a Belkin wireless router. A Windows Vista PC is actually wired to the router, the other computers are on a WLAN.

The router is at http://192.168.2.1/. The wired PC is usually at 192.168.2.2. Other wireless devices get addresses like 192.168.2.3, 192.168.2.9 etc., meaning: Everything is on the same subnet, contrary to my previous wireless router that used different subnets for the wired and wireless devices.

Sometimes the wired PC reports a duplicate IP address error. The "easiest" fix seems to be:
  1. Power the PC down
  2. Power-cycle the wireless router
  3. Start the PC back up

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.
