My wireless internet has stopped working. I have a D-Link Airplus G+ DWL G520+ Wireless PCI Adapter. My wireless internet always used to start up when I started up the computer and I would be able to see the Wireless Internet icon in the system tray along with the D-Link Airplus G+ Wireless Utility icon. The connection icon is still there and it says that the connection is enabled and the signal strength is excellent, the D-link icon however is no longer there and when I open up internet explorer I get the 'page cannot be displayed' message. I dont think it is anything to do with it being firewalled because I have disabled windows firewall and removed my norton internet security. Any ideas?
