Wireless AP dropping users

Madhan Kumar — Sun, 04 Jul 2021 02:52:59 GMT

Dear All,

I have installed an Access point AP1252AG-A-K9 successfully and it was working fine last 7 months. All of sudden it is keep on dropping users. I mean users are disconnected from the AP and then reconnected. I am unable to understand the exact issue. May be an ios issue?. Kindly suggest.

Thanks you

Please provide the console output of the AP (or telnet with "term mon") when it drops users. It should mention the reason of the client disconnect.

It can be interference, have you checked for other APs/SSIDs/non-wifi devices ?

Which band are you using ? 2.4 or 5ghz ? How many antennas did you connect ?

Nicolas
