RAX 120 Shakehand speed very slow
I am using Intel AX210 with RAX 120, the latest version of AX210 driver, 126.96.36.199 of RAX 120 firmware.
I disabled 2.4Ghz for the router, and leave only 5Ghz there.
I choose 160HZ and enabled ofdma on wifi 6.
The shakehand speed is very much not stable though I take my laptop 2 meters away from the router and nothing between us.
In my area, no other 160HZ ssids available, and only 1 another 5Ghz ssid which is on another channel. (I am on 44, and that one is on 36).
The shakhand speed can be from 100Mbps to 1.0Gbps, and usually around 400-866Mbps.
It is rediculous!
When my positition is that good, why I can get 2.4Gbps? And why it can even not be stable at 1.0Gbps?
Is it a firmware issue? Which version of the firmware is the best at this moment?
I understand that 188.8.131.52 is a really bad thing, so should I upgrade to 184.108.40.206 or downgrade to another version?
