Cannot connect >3 wireless clients - "Could not set STA to kernel driver"
Using "OpenWrt SNAPSHOT r35523-aac6df7bdc / LuCI Master 26.221.63536~04f1a7f" on a Tenda BE12 Pro. I cannot connect more than three wireless clients. When I try to connect a fourth, logread -f says:
Thu Aug 13 19:53:53 2026 daemon.info hostapd: phy0.0-ap0: STA 04:e8:b9:ea:5b:00 IEEE 802.11: authenticated

Every one of my devices will successfully connect, as long as I do not try to connect more than three devices.
It doesn't matter if I use 2.4Ghz, 5Ghz, or both. Maxassoc is 10 on both 2.4 and 5Ghz radios.
Any suggestions would be appreciated.
