I have an
Intel Wireless WiFi Link 4956AGN wireless adapter in my Laptop. When I'm running Windows Vista, it cannot see the 5ghz network that my wireless AP is broadcasting.
I know that my wireless card should be able to find the 5ghz band for two reasons. The first is the theoretical reason, that the wireless card claims to support both A and N. A being a standard that only uses 5ghz, it has to be able to use the 5ghz band. The second is a practical reason. I dual-boot into Debian Linux on this machine, and when I'm in Linux, I can connect over the 5ghz band just fine.
I've also made sure that my drivers are up to date in Vista.
This rules out pretty much every fix I've found over the internet and SuperUser. I know that my router/AP is broadcasting, and that my wireless card is capable of connecting. So, my question is: What else could be going wrong? What are some steps I can take to try to connect over the 5ghz band?
