Summary - R7800 & 21.02.0-rc1 : no client connected to Wifi 5GHz
Task Type - Bug Report
Category - Base system
Status - Unconfirmed
Assigned To - 
Operating System - All
Severity - Very Low
Priority - Very Low
Reported Version - openwrt-21.02
Due in Version - Undecided
Due Date - Undecided
Details - **Environment :**
 - Netgear R7800 (Nighthawk X4S AC2600)
 - OpenWrt 21.02.0-rc1 (sysupgraded from OpenWrt 19.07.7 with some basic configuration)

**Problem encountered :**
After doing a sysupgrade from OpenWrt 19.07.7 to OpenWrt 21.02.0-rc1, everything looked fine at first sight, but I have noticed that none of the WiFi clients were connected to the 5GHz WiFi, they were all connected to the 2.4GHz WiFi, which leaded to a bandwidth diminution and my printer was not anymore accessible.
Now, I am back to OpenWrt 19.07.7 and the printer is working fine again.

Sorry I don't have more details on that problem, I am creating that bug ticket to see if I am the only one concerned by that bug.
I don't even know if the 5GHz WiFi was emitting for real or not.
