Max 7 Wi-Fi stations are supported in Access Point mode on Raspberry Pi 4 #3502

Open gentoo-root opened 1 month ago

gentoo-root commented 1 month ago

Describe the issue you are experiencing

As reported in https://github.com/raspberrypi/linux/issues/3010#issuecomment-750324929, Raspberry Pi 4 is limited to 7 wireless clients with its builtin Wi-Fi in AP mode. However, an alternative cyfmac43455-sdio-minimal.bin firmware can be used to overcome this limitation, reportedly allowing up to 19 clients.

I haven't, however, found out a supported way to replace /lib/firmware/cypress/cyfmac43455-sdio.bin in the host squashfs image. I'd like to have a config option or an addon that would allow replacing the Wi-Fi firmware with the "minimal" version to bump up the number of "smart" devices connected to Home Assistant via the Hass.io Access point addon.

What operating system image do you use?

rpi4-64 (Raspberry Pi 4/400 64-bit OS)

What version of Home Assistant Operating System is installed?

6.6.31-haos-raspi

Did the problem occur after upgrading the Operating System?

No

Hardware details

Raspberry Pi 4

Steps to reproduce the issue

  1. Install Home Assistant on Raspberry Pi 4 with the official instruction.
  2. Install the Hass.io Access point addon.
  3. Configure the Wi-Fi access point.
  4. Attempt to connect 8 ESP8266 devices to the access point.
  5. Observe that only 7 can connect.

Isn't this a feature request that belongs to https://community.home-assistant.io/c/feature-requests/13 ?

Let me try to explain my thoughts why I think it is a bug.

I consider it a bug when I can't connect a reasonable amount of Wi-Fi devices. I'm not talking about hundreds, seven is just way too low. 19 is also not an overwhelming number, but it should suffice for entry-level (and maybe even middle-level) automations based on Wi-Fi.

Moreover, when the user tries to connect more devices, they begin to disconnect randomly. There are no warnings about the max number of devices, and it's not the new devices that can't connect, it's random ones. Random disconnects also fall under a "bug" category as for me.

As far as I know, the limitation of max 7 connected Wi-Fi devices is not a documented behavior in HA docs either.

I hope that makes sense.
