Hi folks, I not trying to hijack this thread but I have a similar problem.
Like you gigman, I can't get to internet but I have a good wireless connection showing on my laptop. I can connect fine on my desktop. Both systems are wireless, the xp laptop has a netgear card which was working perfectly up till 3 days ago, the desktop uses a belkin usb adapter. I can connect to the router from both machines. Can anybody offer some help?
PS. I've found the answer - its affectted people with zonealarm firewall.
