BE550v1 - Don't work OFDMA + MU-MIMO and weak WiFi Signal.

Hello, i recently buy BE550 Router and i notice when i select OFDMA + MU-MIMO on WIFI settings, after refresh or after little time router alone switch to: OFDMA only. And after switching it i need restart router, because 6Ghz band is not visible anymore.
Also i notice 5GHz band has much stronger and stable signal than 6Ghz band.
6GHz band from 1 meter has between -43/-45 dBm but 2 meters from router jump between to -46/-59 dBm.
5GHz from 1 meter is stable -25dBm and from 2 meters -30/-32 dBm all parameters its of line of sight. And both 5ghz and 6ghz works separate on 160mhz with ax mode.

Hi, thanks for posting question here.
We may need to confirm some information to understand how you tested the speed.
1.Did you test speed only using one device? What device is it?
2. Did you test speed only on 5GHz band of 3 routers? If so, Did you disabled Smart Connect on Archer AXE75 and Archer BE550 and set different wifi names for 2.4GHz and 5GHz band?
3. Please share the wireless settings on three routers, especially 5GHz wireless settings.
4.Please share the screenshots of speedtest results(using www.speedtest.net) on three routers.
And what is your basic network topology?
Thanks for your cooperation. It is suggested to start a new thread next time if the issue is different for discussion.

I'm updating the status of the new official firmware of the BE550 V1 and hope others can also install it to confirm if the overall performance will be improved.
The official version 1.1.1 Build 20241230 brings a range of improvements and new features to enhance your networking experience, offering better performance, security, and ease of use. This update is gradually rolling out, and users can check for updates on the BE550's web interface or through the Tether App and install the latest version. We strongly recommend upgrading to this version to improve the overall experience.
