How to set up MikroTik hap ac² for home?

Question

Mikrotik

Faced with the problem of WiFi signal quality, I replaced my router with MikroTik hap ac² according to the recommendations from the topic . At first I installed it with basic settings. didn't have time to set it up. Now I decided to tune it up, because the signal quality began to limp again. According to the instructions from the Internet, for some reason, the Internet falls off for me all the time. More precisely, it simply does not exist on devices. Tried several.
Tell me, maybe someone has a bookmark or instructions for setting up so that the Internet does not fall off.
I have 4 devices connected over the air and 1 via cable (TV).

PS The problem is that a very large number of networks in 2.4 GHz up to 3-4 per channel. Switched to 5GHz, but problems with speed and signal are observed. Perhaps due to the fact that I sewed 2 networks, but I'm not sure.
