rtw8852be: [AP mode] Beacon set failed: -2 (No such file or directory)

[sohorx]

I'm currently running on debian bookworm (linux 6.1.94) and I'm trying to use interface in AP mode through hostapd.

Yet hostapd fail trying to set beacon and stop:

> hostapd

The only warning I get from those logs is the ACPI failed evaluation ([ 16.478473] ACPI: \: failed to evaluate _DSM e8c3a8d2-694b-004f-82bd-fe8607803aa7 (0x1001)) but I do not know if it's relevant.

I'm wondering if i'm doing something wrong or if this issue is known and/or already resolved ?

I can start AP mode with the latest upstream driver. Can you share your hostapd.conf?

The ACPI evaluation is used to determine if platform can support some features, but platforms might not define the fields causing message of "failed to evaluate ...". The message can be ignored.

Using upstream driver and Larry's driver (main branch with some fixes [1]), I run hostap with your config under kernel 6.10.2, it can start without "nl80211: Beacon set failed: -2 (No such file or directory)". Could you try it on the new kernel?

Having the same problem. Unfortunately the latest kernel for proxmox ve is currently 6.8.
