I have 2 laptops (Dell Latitude and Compaq Presario)until recently they were connected to a wired D-Link EBR 2310 with no problems. I have Comcast and the modem is a Motorolla SB6320 I believe. Ok, here is what's going on:
The Dell will connect to the internet just fine while connected to router, the Compaq will not. It says is page cannot be displayed server not found or something like that (tried IE and Firefox). I tried shutting down the laptops and powercycling both the modem and router (several times)and still have the problem. I also reset the router back to factory settings. I even did a system recovery on the Compaq thinking maybe a driver needed to be resinstalled.
If I connect the Compaq directly to the modem, it will work. The Dell will connect just fine either way (thank goodness *knocks on wood*).
The Dell is running on Windows XP Pro. The Compaq is on Vista and is barely a month old.
Strange thing is I can log into the router with the Compaq, but does not want to connect to the internet.
I hope I explained everything ok.
