802.1x and HT

I have a WLAN using 802.1x machine authentication on IAP 205's running The authentication works fine but I've noticed the clients are connecting on 802.11a rather than the 11an/ac that I was expecting.


Comparing the output of "show ap bss-table" for that WLAN with one thats WPA2, I'm seeing phy value of a/g for 802.1x and a-VHT/g-HT for WPA, which suggests to me this is actually on the AP side rather than the client side. I found some documentation for AOS 6.3 stating : "High-throughput is disabled on a BSSID if the encryption mode is standalone TKIP or WEP". As 802.1x uses dynamic WEP, will using it prevent HT? If so, any workarounds to that?


Thanks Greg

Re: 802.1x and HT

As per the IEEE 802.11 std, HT rates are not supported on wep and tkip encryption. You need to use aes encryption to achieve HT rates.

802.1X can be used with WEP but is not common. Do you have a need to be using it? Otherwise, switch to WPA2.

Re: 802.1x and HT

Thanks, first time I'd set this up and a lack of understanding on my part. I knew I needed to use 802.1x and the most obvious option was the one I used. Using WPA2-enterprise now and getting the connection speeds I expected.

Thanks Greg
