I travel a lot, and that involves staying at a different hotel every week for a few days. Every Sunday night, when I pull out the router and plug it in, I must set up the root password again. It appears as if the root password is not surviving a power cycle.
Is this by design?
what firmware version are you use?
It should not set up password again when router restart.
I have the latest firmware - 4.2.3.
Every week when I plug the router back in - the password is reset.
Suggest that you try reloading the firmware via uboot. Had similar problems before and this fixed.
I have checked the issue.It is OK.
You can follow @limbot advice,Update the firmware from uboot.
