i have a dlink DI-624 router, so that i can use xbox live (with a wireless reciever connected) in another part of the house. when i first installed it i had no problems but suddenly i cant seem to get it to work, on the network connections screen it says that it cannot identify the problem! the link between my computer and the network has an ! mark on it and it will not allow me to connect to the internet either. when i input the address 192.168.0.1 it will not recognize the router! when the pc is directly connected via the ethernet cable i dont have any problems connecting to the net,any ideas? input would be much appreciated.
