WAP371 APs - deauthentications and disassociations

seventhtiger — Mon, 05 Jul 2021 18:18:39 GMT

Hi all,

My WiFi network suffers from constant deauthentications and disassociations. Sometimes I can't reconnect the laptop until I reboot the AP. Tried what was suggested in other thread which helped the guy but it didn't help me, which was disabling n for 2.4GHz and n/ac for 5GHz, leaving as seen here:

Currently I have there 6x WAP371 and their logs look pretty much the same, that's from one of them:

This network is essentially combined of the following:
- 2x Cisco SG350X-24P

- 2x Ubiquiti NanoStation 5AC (PTP link between the switches/sites)

- 6x Cisco WAP371 (4 at one site and 2 at the other)

Additional info:

All APs work as Single Point Setup and all are affected, regardless of the site.
DHCP is on HP server (first site with 4 APs).

No issues with Ethernet network at all at both sites.

There are three VLANs configured on switches, APs are using only one of them.
No other WiFi network in the area.

Up to 30 wireless clients in total across all APs.
Wireless clients move their devices only occasionally, rarely.
All firmware up to date.

Help.
