The Hardware ============ Windows XP Pro, SP 2 Linksys BEFW11S4 Wireless-B router Motorola SB5120 Cable Modem Cox cable Broadband service D-Link Air DWL-520 Wireless PCI Adapter
The Network Setup =========== Simple. Cable signal into cable modem, cable modem into wireles router. Signal gets sent to one computer. Working like this for months, no problem.
Quick background ================ Connection was a flakey lately, called Cox and they came out to take a look. When they came, everything was working great as they were able to observe. The decided for good measure to switch out the modem for a new, more robust modem. I was fine with that. We put it in. The modem is provisioned, set up no problems.
The Problem: =========== No Internet connectivity. Modem is operating normally. All status lights look great. The router is working great. I can bring up the admin screen no problem. But, no Internet connection. Cox tech was here 2 hours and finally left with no resolution. Things we tried: Replaced cable from modem to router. Hardware reset the router. renew / release.. etc. Deletion and re-creation of wireless connections Did the old routine of turning off the router, modem, powering back up, re-booting, etc. a jillion times and in different variations. No help. It's like the router cannot talk to the modem. I can talk to the router, but that's it. The only thing I can think of is that my "old" linksys router is not compatible with the modem, although I wouldn't think so??
Any help or ideas? Quite a frustrating day!
