Some one keep changing my pass word i like this problem to stop Ty

Seems someone knows the IP address of your router, logs in and resets it and changes your password. Log into your router and change the IP address range like for instance if it's currently 192.168.0.100 change it to 192.168.88.100 or change the range to 195.168.1.100 and then they won't be able to log in any more but make sure you change the router's password as well because they may know it as well. Once this is done the only way to change your setup will be if someone had physical access to your router and held the reset button.
