Desktop Wireless Issue


New Member
Hello , I'm having issue with wireless at my new townhome. I had Verizon Fios Installed and I'm attempting to connect with my desktop. I have a dell Dimension E521 with Vista and I bought a Trend Net USB adapter, and Dynex PCI card. The adapter showed me the wireless networks the first time I used it but its not even recognizing it now when I put it in. I Installed the card and again it would show me all the wireless networks including my own but it wouldn't connect to any of them. My girlfriends laptop connects just fine so I know its not on Verizons end. It asked me for my security code one time and I typed in the password and it wouldn't connect. I don't have it firewalled and I can't find anything that could be blocking it. Anybody have any ideas?? Thanks
