anyone or all could be bad. Try narrowing down the field. If you attempting to connect to a DSL/Cable modem, see if a direct connection to your PCs NIC will bring success. That can eliminate two devices. Don't forget to cycle the power of the modem.
I'm trying to set up my wireless connection but cant access the router config. I tried the address http://192.168.0.1 but it refuses to connect. I have reset the router but that still did not fix it. Anyone have any idea whats wrong?
