Asus released a firmware update for routers that turned out to be problematic. It contains a corrupted threat definition file for the AiProtection utility, so installing it has a detrimental effect on device performance.
Worst of all, Asus engineers considered this update so important that it is automatically installed even on those routers whose owners have disabled auto-update. From the point of view of a cautious user, it looks like a normally working router suddenly broke down without any obvious reasons that could lead to it.

Empirically, it was found that the problem occurs in the operation of the ASD (Asus Security Daemon) utility. To fix it, just delete the /jffs/asd/chknvram20230516 file and restart the router.
To the credit of Asus, it is worth noting that its engineers quite quickly identified a bug in the configuration of the settings file in the server part and have already fixed everything. Users who encounter a problem are advised to simply restart the router, and if this does not help, they need to reset it to factory settings and reconfigure the connection to the provider again.
