Hi all,
I have been using OpenWRT 22.03.5 on my Netgear R8000 for a while, but things have been rocky. The wireless network driver seems to be breaking after a couple weeks.
I am running my router as usual, and some weeks later, wireless completely breaks and does nothing anymore. In LuCi, it now shows a 'Generic' radio on all bands instead of Broadcom. Upgrading the firmware doesn't work (I've tried upgrading to 22.03.6 and 23.05.2). Factory resetting makes the Wireless tab in LuCi disappear altogether. The only thing that fixes it is flashing the stock firmware and then going back to OpenWRT. This has happened three times already.
I have no idea how this happens. It seems like the flash gets corrupted and is not related to a config as factory resetting nor upgrading works.
I see this in the kernel log:
