RT-AX89X - WiFi stops working after a long while/Cable works fine - reboot to resolve temporary

[Teletha]

Hi

I'm using the RT-AX89X router with stock firmware and on the latest available firmware.

The issue we are having is that suddenly the WiFi stops working correctly. Either its very hard to even connect to it or you're connected but cant access the internet (can access local net i.e. router admin page).
This happens very sporadically once every 1-2 months. The only way to resolve it is by rebooting it. Its also only the WiFi part as wired network works without issues.

I'm going to start with a factory reset without using the backup settings, as it has not been reset since i got it in 2021 I've only been doing firmware updates on top of the old ones every time.
But was wondering if anyone else had similar issue if there might be any other way to resolve it if maybe factory reset isn't working. If I'm not resolving the issue I'll have to go ahead with a replacement.

1) consider plugging the router into a UPS battery back up.
2) consider replacing the power brick
3) schedule a re-boot once a week

dirty firmware upgrades are not recommended.

Don't know if this is correct but I got my RT-AX55 working by enabling air time fairness, don't know how but I think it might be something to do with my old J7 Prime and it only affect 2.4GHz. I used to have to schedule a re boot twice every week so you should do that also.

1. Its already on UPS backup
2. where would i find replacement parts in the EU for this?
3. rather not have reboots, then I'd rather replace the router.
