So I recently upgrade AOS to 6.1.3.8. Immediately after we began getting complaints that clients connecting using 802.1x tkip aes are getting disconnected. I visited the floor and notice that the wireless bars in windows are fluctuations excessively between 5.5 GHz and 300 that is from 1 bar all the way up to 4 bars. There are no busy channel; SNR will be 50-40 then suddenly drop down to 17 and lower. I try adding a AP next to the client and it seems worked. I move the AP 10 feet away and it started the erratic behavior again. This an open area with no walls blocking.
Has anyone notice any similar behavior?
