BCM4322 unable to use 5GHZ 802.11n

[zafar9999]

I just purchased a BCM4322 half mini pci-e card with an identifier of pci14e4,432b
I was able to get it to detect my 802.11 2.4 GHZ n network @ 144 mbps but due to the massive amounts of wireless networks in my apartment, there is a lot of slow downs on the 2.4ghz band. I tried using the 4311 and 4322 kexts and I tried using the kexts from the 802.11n enabler.

I am unable to get it to find 5ghz networks. Any insight into the issue would be helpful. Thank you.

Is your router a dual band router? Does it use the 5Ghz band? Not all N routers do.

I have an aiport express set to 5 ghz wireless N. For some reason, the BCM4322 only pulls up 3 networks, all of which are 2.4 ghz. My real macbook pro pulls up about 20.

From what I've ready you gotta use a method (prasys) to flash your card to an Apple vendor ID to enable the extra channels and full speed.
