I had the same problem yesterday. I managed to resolve the issue this afternoon. I'm using Belkin G Wireless Router.
Here's the workaround:
(Note: All your setting will be reset to factory setting, so I guess you will have to run the setup from the Belkin install disc to setup your internet again.)
1. Make sure your Router is powered on.
2. Use a pin to poke the reset hole and hold it for at least 10 seconds.
3. Release the pin. If successful you will see the router starts to reboot (like after you switch on the router)
4. Give the router some time to reboot. (approx 30 seconds to 1 minute.)
5. Try connecting to your router again (http://192.168.2.1
) (your default gateway to your modem)
(Note: If your default gateway is not same as above, use the one you usually do to connect to your router). Use ipconfig from the command prompt to determine your default gateway.
6. Once you are able to get back to your router config page, you can perform your Internet connection setup by running the Belkin install disc provided with your router
Please let us know if you are still having issues. Hope this helps you somehow.
