Why does tx rate mikrotik jump?

Question

WiFi

House and garage, distance 30 meters, line of sight, hung on rbwap2nd, one in ap mode, the other cpe. The speed is bad, I went into the cpe settings, the wireless interface, advanced, there the tx rate is stable 54mbps, and rx (which for ap, it turns out, tx) constantly jumps, then 6 mbps, then 54. I sin that, contrary to the mikrotik documentation, I connected the one that ap over poe via shielded cable, but the shield on both sides is not connected. What to do? Ground the screen? If you change mikrot, then what is inexpensive?

Answer 1

The cable has nothing to do with it.
Microt norms works when properly configured. You just need to figure it out
. As for the noise in the first place, as indicated above, maybe your air is clogged there. or the microwave fries at 200% nearby ...

Answer 2

Look at the noise level.

Answer 3

If the channel is point-to-point, then changing the protocol from 802.11 to nstreme or nv2 can help. But it would be better to use equipment with a narrowly directed antenna to organize the channel.
