Hello

I have CRS125-24G-1S-2HnD
RouterOS 6.42

But error in Wireless:

disconnected, received deauth: authentication not valid (2)
disconnected received deauth class 3 frame received (6)
disconnected received deauth class 3 frame received (7)



How to fix it?

Thanks.

This problem can be for many reasons, security key in your wireless profile, interference, poor signal, channel overload, access list restriction.

I hope this will some how helpful: https://wiki.mikrotik.com/wiki/Manual:W ... Debug_Logs

Hello
security mode - None
All clients in one room.
All clients are allowed access.
The same situation at different frequencies

Someone is attacking your WiFi?

But error:

Have you changed anything in your configuration? Security changed from WPA PSK to none? And all clients have "remembered" settings for the old configuration and computers tries to connect with password?

No changed anything in configuration.

I see the same error for one of my clients since upgrading to 6.42.1
We are using wpa2

I'm seeing the same issues, on 2 out of 10 in my upgrade test group.

I've confirmed that the credentials are correct.

I hear similar tales form other customers, primarily on 6.42rc6 not 6.42.1

I'm also having this issue on 6.42.6. Signal strength -63, so not too weak. Sometimes I also get deauth due to MIC failure (14), for the same device

I have noticed this in my home wlan too...by any chance clients are android devices?

This is mostly fixed for our customers.

Were using the setting in the script in post one of "Wireless woes and how to fix em "

It is caused by congestion.
When reported we look at the network; resolve if internal (such as getting those stupid Direct print printers on the network instead of competing with it}.
If not internal do a scan and determine the best channel; then modify the scan-list in order of preference.

It's a lot better in 6.42.3 as well, haven't tested newer.
