Hello, my router froze up overnight, so I rebooted it, and ever since the logs are showing that it is going OOM about every 10 minutes. First it starts spamming:

May 17 10:44:26 kernel: [ 5872.720019] wlan: [0:E:QDF] NBUF alloc failed 12107B @ dp_get_ppdu_desc:3430

Then it looks like a high memory killer kicks in and kills a process called asd:

Looking back at when the router locked up initially overnight, it seems like it tried to look for a firmware update automatically around 4am, (which is strange because I have auto updates turned off), then started spamming the 'NBUF alloc failed' message:

Any help greatly appreciated!

Im at my wits end here. The only thing I have managed to do is hard reset, factory restore and wait until a sign of hope appears (red wan light, then I only see 2.4ghz and 5ghz buttons lit).

Is there anything else I can do? The ASUS app won’t even detect the router if I scan the QR code, and if it does I can’t connect to the Asus_80 WiFi network that would allow me to flash this beta firmware that apparently fixes everything.

No amount of resetting anything is working. I’ve read about SSH via macOS but can that even be done when the router refuses to broadcast a WiFi network/ip address?

A last resort to load firmware onto an asus router is using the asus recovery tool. here are asus steps for that in the link below. I wouldnt recommend using a beta firmware unless your an advanced user and willing to have problems. Beta usually is buggy hense why beta and still testing. Use the most recent finished / fully developed firmware available for the router model.

Using the recovery tool you will need to connect a pc wired to the router and set a static IP on the pc. just take your time and read instructions fully to make sure you know the next step.

Thanks so much for reply. I just got the macOS version of the rescue mode up, and it “seems” I’ve connected to the router… but upload fails. Should I be messing with any of these settings?

Mikomikotiger · ‎06-25-2023

Gave up on the macOS firmware upload. Unplugged the router and modem and will try to plug both in to see what happens after 30 min.

Has anyone successfully been able to reconfigure WITHOUT backing up settings prior to resetting? The hang up I’ve run into has always been connecting the router to any device (MacBook, iPhone etc) for initial setup. If I could access the gui, then my last 24 hours of work on this thing would be worth it!

Sorry you're still having issues. All my PCs have an Ethernet cable directly connected to the router so I'm not sure how the router responds to wireless connections with this problem. Unfortunately, I can only tell you how I was able to fix the issue for myself. I hope you can get it up and running soon! Good luck!

Mikomikotiger · ‎06-25-2023

Latest trial is to start up the router without a wan cable connected. Wan light is still red and reboots still happen. Reset button doesn’t even work except to put router into rescue mode.

is there a special amount of time to hold the reset button down so it only resets, not boots into rescue mode?
