The Wi-Fi network on Mikrotik falls off. What could be the problem?

Question

Computer networks

There is a Mikrotik 4011iGS router, 7 Mikrotik wAP ac RBwAPG-5HacT2HnD access points connected via Mikrotik CRS112-8P-4S and 50+ clients and managed via CAPsMAN.
All clients have the same problem. Periodically, about once every two hours, the network falls off for 15 seconds, the connection to Wi-Fi does not disappear at this time. The logs are empty.
For clients connected via cable, everything works perfectly.
The problem is both 2.4 and 5 Ghz. AES encryption only, DHCP Lease Time - 8 hours. Firmware is always the latest.

Answer 1

Falls off how?) where is the trace on 8.8.8.8? Ping on the fallen off client goes to the gateway?

Answer 2

It can be seen that they did not delve into the issue of wireless communication. Check the time is equally set on the points and what protocols you use for communication

Answer 3

Well, the logs should be nothing is not true, IMHO. Firmware try RoutetOS LTS and not testing or current

Answer 4

Good afternoon, I think everything is ok with your settings, because. there is nothing complicated and tricky about them, so that everyone falls off at the same time. Look towards external factors. At me similar was also puzzled about half a year. Until I invited a chela with a special device. It turned out to be a powerful microwave on the floor below the office where my work was. Like this

Answer 5

perhaps the Wi-Fi channel is changing to inaccessible to mobile phones, etc. due to clutter - for example, when everyone goes out at lunchtime, both yours and others in the building, or even for unknown reasons. Therefore, for a while, the channel is less involved. Try manually setting it on the router.

Answer 6

Studio configs. Guessing from the coffee grounds, to the aunt around the corner.

Answer 7

I disabled the RSTP switch on the bridge interface, the second day everything seems to be ok. Maybe that was the problem.

Answer 8

An error in birdge configuration on access points can cause this issue when using capsman.
The logs will contain errors like bridge port received packet with own address as source address.
