Hi
I have a problem In my 912 and it shows the mac of my home router send deauth and i have many deauth issues from other customer
How to prevent from deauth and what cause deauth?
Wlan1:data from unknown device (mac) send deauth
A deauth is when the station (the mikrotik) tries to kick a client off the wifi, probably from too much data loss from a weak signal, or noisy frequency.
If the client doesn’t receive the deauth, it may try to continue communicating. At this point the Mikrotik may see the device as unknown since the Mikrotik has already sent a deauth and removed it from it’s registrations table. If it gives you the mac address of the client, you can determine which devices have wifi issues with the Mikrotik. Do all wifi devices have the problem?
Stations often output a more powerful signal than the client. This typically allows for a faster download rate than upload. However, it also means you can’t use the signal strength on the client as an indication of the overall signal strength. The station may be having a hard time receiving data from the client.
As for why it happens frequently, you may have to troubleshoot your environment. Does it happen when devices remain within 15 feet of the Mikrotik, and no objects in between?
