Good signal, poor TX rate Litebeam AC Gen2

I have a Litebeam connecting to a Mikrotik sector. Signal strength is good, but TX rate is just 6.5 Mbit/s with RX 500Mbit/s and up.

What can I do to fix this ? Mikrotik sees signal strength as -59 dBm, TX rate as 520mbps and RX also as 6.5mbps which makes sense , but why the 6.5mbps?

Any suggestions here ? I'm running OpenWrt 23.05.3 r23809-234f1a2efa / LuCI openwrt-23.05 branch git-24.073.29889-cd7e519 What am I doing wrong here?

Just transfer some data?

It is slow with speeds of less than 0.50mbps on upload when doing a speed test with https://www.speedtest.net/ On the other side of the connection where the gateway is I get 20mbps upload speeds.

MCS0 ususally is set by powersaving for easy spinup when traffic starts.
Try something like fast.com (set all editable params to 30) or https://www.waveform.com/tools/bufferbloat or speed.cloudflare.com
To have such effect radiowise you need to have path between routers via ventilation duct or old fridge

I will try that , although I do not have this issue with Mikrotik. I have seen the RX rate on the Litebeam with OpenWRT go up with usage , but not so much the TX rate which is worrying. Also , speedtest.net's download rate is good behind the LiteBeam , but not upload.

Have a look at this on the Mikrotik side. The top one is the OpenWRT connection. Things don't look right to me there

What else can I try here ?

-85dBm is very weak

You are looking at the wrong value. Look at the top one: -59 dBm. That is the connection that has the problem.

10dbm signal fluctuaion means adjustment problem

"10dbm signal fluctuaion means adjustment problem"

How can this then be fixed ?

Compass and screwdriver?

How can it be alignment when the signal strength is good ?
