Question: What to do if you forgot router password?
Forgot router password and failed to log on to router’s configuration page? I hate to be in this situation, because as I know the only way to solve this problem is to reset the router back to factory default setting by pressing reset button for 30 seconds – 1 minute when it’s powered on. You are always advised to read router manual to understand the correct reset method.
After having successful router reset, you should be able to log on to router's configuration page by using default username/password and reconfigure the router. Probably you can have a look on this wireless router or wired Ethernet router configuration example to help you more.
