We have a location that has 3802 AP's, on a 5520 WLC operating on 8.2.170 code. The WLAN they are connecting to currently is configured for both WPA-1(tkip) and WPA-2(aes) We are moving away from having both encryption protocols enabled, but currently this is the configuration. The Win10 clients have two GPO wireless profiles, 1 for WPA-1 and the other for WPA-2. The WPA-2 profile is preferred. We are moving away from this, and will be removing the WPA-1 GPO profile from these machines. However, we have started seeing issues where clients will connect and prefer the WPA-1 profile, and will show connected 802.11a on 5GHZ. When attempting to connect to WPA-2, these clients would connect, but some could not pass traffic, or others would bounce back to WPA-1. Has anyone experience this issue?

I understand it is not a good scenario, and we are moving away from it. I was more interested if there was a potential bug we were hitting on the 3800 or WLC 5520 on 8.2.170 that was contributing to this.

No. We are seeing issues with windows clients connecting to WPA-1 and not WPA-2 on the same ssid with both enabled. When trying to move them to WPA-2, they fail sometimes, or immediately connect using WPA-1. We have only seen this with Windows clients, but that is 99% of the clients we have. We are updating drivers, then plan to test to see if we can reproduce the issue.

What Windows OS?
Can you try to get a BYOD running the same Windows OS or Windows 10?
