Cannot obtain from DHCP server, until remove wifi card driver and reinstall

using Smartzone 144 v.5.2.2.0.1563 / R650 AP v.5.2.2.0.2069

Some of the user PCs, both win 10 and win 11 cannot obtain IP from DHCP after 802.1x authentication. Wifi show connected but no internet and checked no IP obtained.

Checked in the troubleshooting, can see the client finished the authentication and talk to the DHCP server but it just cannot get the DHCP. One Win2012 DHCP is tested first, and a new one using Win2022 have the same result.

Strange that with the wifi connected, removing the wifi card from device manager and rescan and install again and it will work fine.

Sometime connecting to a SSID with WPA2 in different VLAN (and successful) and then connect back to 802.1x it can also get the IP.

I totally have no idea what's going on and why, anyone have the same problem before?
