Hi,

It can be an issue with the modem or with the line. When the line drops the link then the modem shows only two lights. And, when you power cycle the modem (unplug and replug it) it establish the session again with the comcast.

So, i'll suggest you to get the line checked first and if comcast finds that line is working fine then get the modem replaced.

you can't set teh modem to bridge mode, however, you can set the router to bridge.
The linksys should have bridge mode configuration in the uer guide.

connected the 2 router together
configure the IP address of the liksys to be inthe same subnet as the moem, but out of the range of the DHCP of the modem. ie. DHCP address 192.168.0.2 through 192.169.0.100, the linksys should have the IP address as 192.168.0.200
disable the DHCP on the linksys
setup the wirless just the way you would if ti was the modem.
connect from the modem LAN port to the LAN port on thelinksys. leave the WAN port open.

This RCA DCM 425 is a cable modem only its not even a router, its just a plain cable modem that is being provided by some cable company like Cox and Comcast, try searching again for a different box there they have a brnad name of Linksys, Netgear or Dlink because those are the common manufacturer of wireless router ...

Hope that helps............

Try resetting the modem whenever you change between those PC's some NIC's will hang a cable modem stuck on an address.

I got a different modem from Comcast....a Motorola. Then I got a Belkin USB network adapter. You can plug in an ethernet cable into the Belkin and plug the other end into the computer USB input. This works well for older laptops that have no ethernet input. Then you call Comcast and they configure it over the phone and Viola! It works. So if you have an older laptop like I have, get a Belkin F5D5055 Gigabit USB 2.0 Network Adapter. Plug it in to your USB input and then plug in the enthernet cable from Comcast. Hope this helps someone.

This one is for a DCM 315, it should be pretty close and might work. http://a1212.g.akamai.net/7/1212/6718/20030131/comcast.download.akamai.com/6718/help/cmdrivers/RCA_315.zip
