Neighbors and stealing wifi

[RussellObrien]

I have a neighbor who asked me to use my wifi when she moved in. Two months later she is still using it! So I PUSHED THE RESET BUTTON! MAD AND DETERMINED. SO, I AM TRYING TO CONNECT THE BOX AGAIN BUT IT WON'T WORK. PLEASE, if you can help let me know. I have already went through the automated system 4 times with no relief

[EG]

After a reset to factory defaults, the gateway device reverts back to its default values. They are on a label on the bottom or back. 

Everything that you changed / customized also does , so the settings will need to be re-done from scratch.
