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 220.127.116.11, 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.

Make sure your router's WAN port is set to dynamic IP. If the light on the front doesn't glow/blink for the WAN port, try a different cable. If a different cable doesn't work it's probably toast. :( This problem appears to be directly linked to the relationship between the WAN port and the modem. Given that the devices can connect to the router, but not internet, it has to be the WAN. Sometimes if the modem goes out it will send too much voltage through to the router and fry the WAN. Had that happen to my parents router. If the above doesn't "fix ya" then try a different router.
Worst case, you might have to put a wireless card in your PC and bridge the modem (wired connection) to the wireless card and broadcast for your wireless devices. At least until you get a new router.
* NOTE: If you tried to set-up the WRT-160N Router previously, but failed, with the Router ON, press the "Reset" button on the back panel and hold it down for 10 seconds, then release. This will reset the Router to factory settings and erase all previous data. Then do this 1. Hook up the Linksys WRT-160N Router to the modem(cable, DSL or satelitte) 2. Hook up the Linksys WRT-160N Router to your computer via a LAN cable with the LAN cable in Port #1 on the Linksys WRT-160N Router. 3. Type http://192.168.1.1 in the address bar of your web browser. 4. Log-on to the Linksys WRT-160N Router with these log-on credentials: Username: linksys (lower-case) Password: admin (lower-case) 5. Click on the "Clone PC MAC Address" tab. 6. Click the "Clone PC MAC Address" button. 7. Click "Save", click "Continue". 8. Click the "Wireless Security" tab. 9. Choose "WPA2 Personal - TKIP/AES" for encrypted security. 10. Enter encryption password (passphrase). 11. Click "Save", click "Continue". 12. Exit the web browser. 13. Disconnect the LAN cable from the computer and Port #1 on the Linksys WRT-160N Router. In about 5 seconds, your wireless connection should be up and running.
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.
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 ...
