We have a customer who is complaining constantly about their WiFi
We've tried everything - including installing a second MT router and setting up CAPsMAN
Here's an extract from the log
The signal is strong - so that's not it (and CAPsMAN is handing off correctly between the two AP's when the signal is weak)
Latest attempt to fix it was to turn off the 5G network but still seeing problems
Config works fine for other customers.
Help!

Similar thing happened to me - extensive data loss and deauth (2) errors, despite a decent signal.
The only thing that worked was switching to NV2 - zero disconnects since.

It's not always a signal strenght problem. Check the signal noise ration SNR. We had similar problems with a good signal but link quality was very bad.
We hat intererences by an other device, which was too close to the antenna.
Check SNR and/or noise level on the device.

Sorry but i see no problems, general speaking, in the log...!
The log begins with a "registered to other interface" which is ok, the client just connected to another CAP...
Then we see a reject rule you have manually added.
After that, we have a "received disassociation...." with a reason of "station leaving" , this means that either the mobile wifi went to sleep mode or the wifi was turned off manually etc...
Then an "extensive data loss follows" , i see a bad signal connection after that so it is obvious that indeed the signal went really bad until the AP could not send data to the client anymore... It could be interference, the client device wifi got turned off etc...

So are those "problems" happening to this device only? Because only one device shows these "problems" in the log...

Go to system logging and enable debugging for the wireless so we can have more detailed log descriptions....
Most probably that specific client device doesnt like something in your configuration...
