i'm connected to a router. the network connection icons shows that the network is connected, but i cannot connect to the network or the internet. even when i try to ping the default gateway, it says request time out. i tried fixing the winsock and resetting the tcp/ip but still i'm not able to connect to the network. also when i type the ip address and everything else manually the network connection shows connected but only the sent icon blinks and the received icon stays dull. and when i try to obtain ip address automatically. the network connection icon says limited or no connectivity. i have both lan and wireless connection, and this happens for both of them. any suggestions please.
