WLan performance not good on RT-AC87u with 384.4 (features from 382)

[Lukass2000]

Hi,
yesterday i flashed asuswrt-merlin 384.4 on my Asus RT-AC87u.
Have made a complete new installation, factory reset and set all settings new.
Before i used asuswrt-merlin 380.69_2.

Now I noticed that the wireless range is a lot lower (2.4GHz).
Before I had in my office a signal from -60 to -65 dBm.
Now with Firmware 384.4 just more to -80 dBm.

Hav all checked, the settings are the same with both Firmwares.

Is this normal?
Is the Wlan performance with 384.4 less well?

Thanks

My AC87U looks great with 384.4, try diable for airetime fairness/beamforming in 2.4G/5G
