Wifi breaks on MikroTik Hap Ac Lite. How to setup?

Question

Mikrotik

Hello.
There is MikroTik Hap Ac Lite (952Ui-5ac2nD). Channel 100 Mbit.
From the main users: 1 computer via cable, 2 TV via Wifi. The network is set up on the PC via the Home Media Server. There is a WiFi break when watching through Smart TV through the OttPlayer player, as well as when watching movies on TV over the network. Changed firmware, wrote to technical support, reconfigured, nothing helps.
Only this configuration is

I tried to configure it as described here https://netflow.by/blog/item/129-nastroika-mikroti... , but it didn't help either.
Tell me what to do?
Thank you.

Answer 1

There is nothing criminal in the config. So it's either in the hardware of the router itself (lack of resources), or in the clients.
Let's start with diagnosing the router - open the profiler ( /tool ​​profiler ) and see how CPU is loaded. Also see if there is information in the logs on breaks on WiFi. Try to select another channel for 2.4 network and switch to onlyn mode

Thank you. I can only do it in the evening.
I tried, but channel 5 also falls off
