If a power cycle doesn't fix the problem, then the firmware is probably corrupted
You will need to reset the firmward.
Hold the power/reset button at the back of the router for for 20 seconds while it is on, unplug the routers power, then continue holding it for 20 seconds.
Plug the power back in and let go of the button.
This will mean you will have to reconfigure all the settings again unfortunately.
