How to set preferred band to 2.4Ghz

Hi,

i'm trying to figure out how to force a PC Client to connect to an AP via 2.4Ghz band instead of 5Ghz: the network has multiple access point (2.4G and 5G) under the same SSID but there's bad signal for 5ghz ; Windows is ignoring that and it is still trying to connect to those bad-signal 5ghz APs.

The Client runs Windows 10 Pro and its NIC is an Intel AX200 Wifi 6
Until now i tried:

  • Driver Update (22.70)
  • Device Manager : Changed settings to "Prefer 2.4Ghz", but nothing changes
  • NetSetMan : When manually switching to a 2.4Ghz AP the software almost crashes ; still, no issues encountered when switching between 5Ghz APs. Here is a screen from NetSet https://imgur.com/a/7zNugnh

At this point i'm thinking of setting minimum RSSI of APs via UniFI panel (minimum RSSI for 5Ghz access point only) so that they don't allow client to connect if signal is below -70dbm.

Anyway, it seems REALLY STRANGE to me that i can't manually set band preference client-side. Do you know any other method? Via cmd maybe? Or Powershell Network config?
