We ran into multiple TKIP issues with clients about 2 years ago and
disabled all TKIP use at that time. We have around 45k unique clients
and they all seem to work fine with TKIP disabled. The other think we
did at the same time was drop all the lower speed rates

We have had several tickets opened for this issue. We use mixed AP models
3702/3602/3502/1142/1131. We allow both WPA/TKIP and WPA2/AES under WLAN. I
don't have details about which APs did clients connect to when the issue
happened. I have asked clients to provide details but no replies. Has anyone
confirmed this was caused by the WPA/TKIP setting?
I searched one client MAC address in Prime Infrastructure and it appears the
client was connected as WPA2/AES.
Our syslog shows following error for this client:
*Dot1x_NW_MsgTask_2: Mar 24 15:00:15.733: #DOT1X-3-WPA_KEY_MIC_ERR:
1x_eapkey.c:703 TKIP MIC errors reported in EAPOL key msg from client
28:cf:da:ee:51:52
I opened a case with TAC. TAC required the "debug client" output but I have not
been able to collect that yet.
