I have an RT-AC68U Asus Router. The admin password stopped working. After many unsuccessful tries, I did a factory reset.
After the reset, the router gives the following error:
The resource, Asus RT-AC66: Cannot Login Unless Logout Another User First, suggests using
ssh if possible:
This error is usually caused by improperly closing router’s WebUI. This can occur if you are logged in and lose connectivity, or if your browser crashed.
Fortunately, the fix is simple… Assuming you have SSH enabled.
First, SSH into your router and run the two commands shown below.
admin@RT-AC66U:/tmp/home/root# nvram unset login_ip admin@RT-AC66U:/tmp/home/root# nvram commit
However, after a factory reset, the ssh is not enabled.
The other suggestion is:
If you do not have SSH or telnet enabled, you can just power cycle your router.
I have already power-cycled the router and that did not resolve the issue.
