using Raspberry Pi 4 (using 64bit OS)
[balenaOS 2.56.0+rev1]
Issue:
I’m unable to connect more than 8 wireless AP clients on balena-hotspot. This issue might stem from RPI build but I wanted to see if anyone has a solution or has experienced this issue.
My next step is to try an WiFi adaptor dongle instead of the native WiFi chipset.
The only solution for this unfortunately is to use a dongle. As the RPi kernel maintainer explained the vulnerability fixes to the WiFi chip firmware take up its available state memory, so they have to limit more and more the amount of allowed AP clients. Not the smartest of designs from the looks of it unfortunately…
thank you for the clarification. I’ll try a wifi adaptor
Tested Wifi dongle: The Panda Ultra Wireless-N Adapter (PAU03)
Successfully connected 18 clients (did not test to MAX connection limit).
The only software change was to configure /mnt/boot/system-connections/balena-hotspot with appropriate USB wifi interface. In my case this is wlp1s0u1u1. Use nmcli d with dongle connected to check your interface name.
