Netgear WAX218

Hi, I have flashed OpenWrt 23.05.0-rc2 r23228-cd17d8df2a on Netgear WAX218 AP but I cannot see any wireless interfaces and I am always seeing "System running in recovery (initramfs) mode." message. Any ideas on what can I do?

you flashed the wrong image .. ?;a=commit;h=7801161c4bb2413817b3dfd01695050e2da27bf3

Why do you say that? I have flashed it based on the instructions: first, then sysupgrade

the "initramfs" would indicate you didn't, but I'm only guessing ....

I've seen that more people had this problem in another thread but it is closed due to inactivity... Maybe instructions don't work anymore.. Anyhow, what can I do to recover from this state?

no idea, I don't own the device, but I would start with nmrpflash.

To get back to factory firmaware? I somehow suspect that there should be a way to fix this from openwrt itself...

if it's not in the git commit, or posted elsewhere on the forum (I haven't looked), nmrpflash would still be my no 1 choice.

Which stock firmware was it on?
I'd nmrpflash to the earliest stock firmware you can find and try again.

it does not respond to nmrpflash

I have seen different behaviors depending on devices. Some require to power on before launching the command, some after. It's a matter of seconds. Try several timings between powering on the device and launching the command.

Should I connect my computer directly to the access point via ethernet cable or should it go through the switch for nmrpflash?

I have access to UART, let me know if any info would be needed for this device

Directly, and only the computer.
nmrpflash works with every Netgear routers I have been able to use. But ... take care of the timing start. Try several until you find the right one.
Also something that I forgot : at the end of the process, there is a message telling you to reboot. Wait 1 min before doing so. While monitoring a device with serial link, I have found that the writing process may not be ended when the reboot message is displayed.

WAX218 is just an AP, not a router, could this be that it does not react to nmrpflash?

No, it shouldn't.

I have these options via UART:

Please choose the operation:
2: Load Linux System code then write to Flash via TFTP.
4: Entr boot command line interface.
9: Load Boot Loader code then write to Flash via TFTP.
e: Erase Boot Loader ENV config.
ESC: Please input ESC to run Burn-in testing.

Can I reset from here somehow?

I'd go with option 2, but watch the console while your press the reset button, and fire nmrpflash.

Nothing happens when I press reset button and no matter for how long

bummer, guess serial is needed for recovery/going bak to stock, unless if can be done from within openwrt.
