Wifi says connected,but no internet

after a reset the default for the router would be 192.168.1.1
BUT
you are showing a default gateway connection on your ethernet of 192.168.1.254

Also the wireless adapter is a Atheros AR5007 and under vista , any change in routers or router settings can cause issues

can you explain what you are connected to using the ethernet cable ?

and you should update the wireless driver from the manufacturers website - if that does not work - then from Atheros site

whats the make and model of the PC ?
