I have a HP Pavilion laptop PC with Vista which has been working fine for 2 years.
It recently developed an issue where "it cannot find any wireless networks".
Other laptop computers in my house can connect with the Wireless Router and work fine, so it is not a router problem. The laptop will connect to the network if I plug an Ethernet LAN, but refuses to give visibility of the wireless network. I have run SFC, but that did not find any violations. The wireless card itself seems to fine when viewed in the device manager and yes it is switched on.
So this is driving me mad, I really do not understand why wireless on my laptop PC has stopped working.
