mairelina, if all was well 2 days ago then resetting the router should fix your problem. usually a small button on the back of the router.

chelliepooh, you need to check that the router's wireless function is on. connect using the ethernet and go to the config page (usually 192.168.1.1) make sure wireless is on and security is set to wpa-psk.
