I have a serious problem, a company official has changed the login password and we no longer have access to our router, a WRT1900ACS, and both router parts are with OpenWRT versions, so I would like to know how I can do it. have access to the router because I tried to use the RESET button and the same did not work, all help is welcome, as we have no access to the Internet since it has been deconfigured, only local network is working.
nothing happens when I press the reset button, I think it must have been disabled when they have changed the router password, I tried all the possible reasons in the wiki nothing worked, both parts of the router have this problem
Follow these three simple steps to do a hard reset on your router:
With the router plugged in and powered on, hold down the reset button for 30 seconds.
While still holding down the button, unplug the router from the power source for another 30 seconds. You can do this by unplugging the power cable from the wall or by unplugging the power cable from the router.
With the reset button still held down, turn the power back on and hold for yet another 30 seconds.
You just need to use the failsafe mode. Head over to documentation and proceed to how the failsafe works and implement it. Then change your root password and any config if you like and you can get back control of your router.
