AX86U Pro errors started recently

[Chulamin]

Hi,
I recently started seeing these errors intermittently. The router is working fine but is there cause for concern over a potential hardware failure?
Thanks.

It likely indicates the presence of a bad block in the flash memory. I'd start by making sure you have a backup of your current settings and JFFS partition (Administration - Restore/Save/Upload Setting). Also make sure you have a copy of your currently installed firmware to hand.

If you SSH into the router you could run ubinfo -a to gather some more information.

I think my next step would be to perform a hard factory reset. And then, after the minimum amount of configuration necessary to have it operational, go and restore your settings and JFFS partition.

I'll do that thanks. it's still under warranty. I'll check in with Asus as well. Thanks again.
