Hi All,
We currently deployed a new virtual controller setup with 30 AP's and around 300 clients.
These are aruba Type 515 Ap's running 8.5.0.2.
We receive daily complaints that users have network interruptions lasting 20-30 seconds, they stay connected but don't have any access whatsoever.
When we monitor this we see deauth's being sent from the client workstation to the AP:
Traced 802.11 Management Frames
-------------------------------
Timestamp stype SA DA BSS signal Misc
--------- ----- -- -- --- ------ ----
Oct 18 13:25:45 deauth client mac ap mac ap mac 0 Unspecified Failure (seq num 15)
most of the times, we see an eventid "6105 - deauth after EAPOL key exchange sequence" on the workstations.
These workstations are most of the time Windows 10 with various intel NICS, we updated these nic's to the latest driver (01/09/19) but the issue seems to remain. this happens once or twice during the day.
The only difference we have with our other IAP clusters is that we have High Efficieny enabled, but only 2 clients out of 300 is actually using this. We did saw that this could cause issues even on 802.11ac but we thought that a driver update would fix this.
Has anyone bumped into this issue before? We haven't disabled HE yet for the time being.
Thank you!
Sergio
