Norton has expired. Uninstall that, get something else. I won't write at length about this.
My HP Pavillion dv4 laptop suddenly stopped connecting to my wireless network. If I check the status of the WLAN device on the HP Wireless Assistant it shows up as "Enabled" but when I go through the Windows Vista "Connect to a Network", I can't see any available networks. If I then click on the Windows option to troubleshoot network connection problems, I get a message saying that the wireless functionality on the computer is disabled and that I should enable it in order to connect. In other words, the HP Wireless Assistant is telling me that the wireless device is enabled but for some reason Windows says the device is disabled. The Windows Device Manager shows the Wireless Network Adaptor as working properly.
Any idea as to what might be happening or any tests I could try will be greatly appreciated.
