- RCA cable modem
- Belkin router
- Computer running Windows Vista

Out of nowhere, I'm no longer able to connect my desktop computer to the internet via ethernet. Using another computer, I've managed to narrow down the problem to my desktop computer. Not sure if it's a setting problem, a problem with the network adapter, or what. I can connect other devices via wifi over the router without a problem. Cables are fine, modem is fine, router is fine.

Here's what happens:

- It seems to connect to the internet only momentarily, but as soon as I try to open a webpage, the internet connection drops (can still connect other devices through the router).

Not really sure what to try....

sounds like a failing nic.

Post the results of a ipconfig/all for review

OK that looks good.
do a ping 192.168.2.1
do a ping yahoo.com

both successful?

if so do a ping yahoo.com -t
this will run it continuously until you do a control C to break out. Run it for awhile to see if you lose the connection.

 

[joshmcdonnell85]

192.168.2.1 is fine. I can access the router setup utility.

Can't ping yahoo.com though. Request times out.

 

[Wand3r3r]

in the dhcp server remove 192.168.2.1 for dns. Only list 24.226.1.93
and try pinging yahoo.com again after a pc reboot.

Router is not forwarding dns requests which can make it seem like you have no internet.

 

[joshmcdonnell85]

Sorry, how do I access the shop server to make that change?

 

[joshmcdonnell85]

I mean the "dhcp server". Damn autocorrect on my iPhone!

 

[Wand3r3r]

you logon to 192.168.2.1 and edit the dhcp scope.

alternately you could just assign yourself the same ip address, subnet and gateway with dns and see if that works.
