I have a toshiba laptop with an Intel Pro/Wireless 3945AB6 Network Connection (I believe that means my wireless card). I am unable to connect to any networks. I can see all networks in range of my laptop but when I try to connect, I get a Connection Not Successful window. When I try to diagnose the problem windows is not able to find one. I've checked the device manager and it says that the device is working properly. I have tried connecting in two different places. Both times, I was unable to connect with my laptop while my iPod Touch was able to. I believe this happened after the last update (at 3:00am PST). I was able to use my wireless connection normally for the first 2 days after installing windows 7.
