[mgrouch]

Much more difficult to connect to my home wifi.
I had to do 30 attempts or so.
I see error in dmesg log

Downgrading the kernl to 5.4.83-5 was not enough to fix the issue here. I had to downgrade linux-firmware to 20201218. May be linux-firmware is the only culprit after all

Using Raspberry Pi 4 8G, 64bit OS with Linux 5.10.17-v8+ #1421 SMP PREEMPT Thu May 27 14:01:37 BST 2021 aarch64 GNU/Linux.
