Today, I have upgraded Tumbleweed release to 20240124 and 5G Wifi stopped
working after the upgrade. Yet, 2G Wifi connection still works.

My WLAN controller: Intel Dual Band Wireless-AC 7265
My Wifi Modem Router: ASUS DSL-AC51

Reproducible: Always

Steps to Reproduce:
1. Connect to a 5G network
2. Wait 5-10 seconds
Actual Results:  
You get the "Connection [SSID-5G] deactivated. The Wifi network could not be
found" error.

Expected Results:  
It should connect to the 5G network.
