I built a new PC here at home. Vista buisness x64. ON my home network it connected to lan and internet straight away useing a network cable. I disconnected the network cable and then installed a wireless network card.
It to connected to lan and internet.
Took the pc to the office this morning and it connected to the lan ok (wireless) but wont connect to internet. I connected a network cable and same thing. Lan but no internet.
I connected a notebook to the network cable and it got lan and internet.
I activated its wireless connection and it got lan and internet. Back to the new pc, lan and no internet.,

Why?
