Re: Reseting "Bridge mode" in RCA DCM 305R cabel modem
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 18.104.22.168, 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.

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.
First try connection the Yellow ethernet cable from the rca modem to your computer's network connection. If you get a connection this way, then your modem will work with a ethernet cable. If not, then call Comcast for help. The modem ethernet out to computer port must be connected to the wan line of the router. Then you can connect an ethernet cable from your computer network connection to one of the 4 ports of the router. For wireless connections you must set up the router and wireless adaptor with the same settings to connect. Follow the routers directions.
It sounds like the LInksys that they replaced was also a router. A router will route packets to multiple pc's that are connected to it. The cable modem just sees the router as 1 pc. When you use a switch, the cable modem will see all of your PC's. and Comcast just allows 1 pc. You will need to buy a router to use more than 1 PC which will be cheaper than using Comcasts Home Networking service which will network up to 4 pcs
ok, ur old modem was configured for those two devices to work to gether
so u have to do the same here
*have ur modem connected directly to ur comptie
*go to ur command prompt if u have vista ( start * search * type cmd)
xp (run then type cmd)
the type in the screen that poped up ( ipconfig) enter
*look for default gateway type that in ur browser address
*should take u in ur modem interfase go to (advandced | PPPlocation | then set that modem on
BRIDGE MODEM and the modem should restart then connect router that should do it
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 ...
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.
