I just recently, went from a wired Nic to a Wireless Nic in my machine I built that I use for virtually everything. The driivers are installed fine an the card works an can connect to the AP. However, when I open a browser an try to go to a page I can't bring up anything. However, it will retrieve the windows updates an such. It doesn't really show the signal in the windows wireless program.
