I conducted tests today with a Rpi4 4Gb RAM as a wireless access point and I wasn't able to connect more than 8 devices. But then I want to be able to connect at least 20 devices. Pls, help.

Same problem here, 8 clients connected, no more. RPI4 (4g ram), Buster updated.

In the end, @pelwell is right here #3010 (comment), so if you're just looking to increase the number of connected clients, then take a look at this table iiab/iiab#823.

Take 7.45.18.0 (follow the link) and replace /var/lib/firmware/brcmfmac43455-sdio.bin (of course, make a backup first). Reboot.

I've done it 2 days ago and until now I see no issues, stability seems okay, 20 clients connected. Check this Github comment https://github.com/raspberrypi/linux/issues/3010#issuecomment-788323744
