Yesterday I've upgraded OpenWRT on my Xiaomi Mi Router 4A Gigabit Edition to this version:
https://downloads.openwrt.org/releases/24.10.0/targets/ramips/mt7621/openwrt-24.10.0-ramips-mt7621-xiaomi_mi-router-4a-gigabit-squashfs-sysupgrade.bin
I'm not 100% sure if it worked before, but I can't get clients to connect to 5GHz networks. Scanning on the router works fine and non-hidden SSIDs from my router are visible to other clients, but trying to connect looks like this in logread -f (after adding option log_level 1 to config wifi-device 'radio1' in /etc/config/wireless):

I've even tried configuring a network without encryption, but it behaves the same even then..
Can anybody help me? I've got no idea what to try next...
Thank you,
kind regards,
