6205 Desktop Unable to Connect to Wireless N Network

In my adapter settings under 'Wireless mode' the current option is 802.11a/b/g. There is no wireless mode that includes wireless n. Yes, wireless N is enabled in the adapter settings under '802.11n mode'

I have no idea why this is happening, and anytime I try to connect to my 5ghz wireless N band on my router it simply won't connect. I am on the most recent Intel drivers for my 6205 adapter. I would really appreciate some help here, if you have any other questions to ask please feel free and I'll answer as best as I can.

Should have mentioned a few other things...

I'm on Windows 8.1 x64

I've tried fiddling with settings in my router and the adapter. It will connect to the 5ghz band when that band is enabled in mixed mode OR 802.11a mode. Again, I think this all relates to the adapter settings which offer every option (a/b/g) EXCEPT n.

I've tried uninstalling/reinstalling drivers


Hello Bacardi,

You may want to have the encryption set to WPA2-AES, avoid any option related to TKIP and use channel bonding (40 MHz) as per articles below. Intel WiFi Products; Data rate will not exceed 54 Mbps when WEP or TKIP encryption is configured Wireless Networking; How to configure 802.11n channel bonding on Intel Wireless adapters Wireless Networking; What are the recommended settings for 802.11n connectivity?

Here's the solution that will most likely work.

You need to enable WMM on the router's QOS settings.

The reason is that compliant IEEE 802.11n WiFi adapters must have WMM enabled to get the N speed (GHz band doesn't matter). Non compliant ones like your Atheros will still run on N speeds despite the WMM being disabled.
