Instructions for activating root mode


HI…can you tell me the password for root for Rachel? I need to change the wifi name and the hostapd file is owned by root.

The default login/pass is pi/rachel.

Thanks James. I am logged in as pi/rachel. I edit the hostapd file just by changing the wifi name to EDUHUB and when i try to save it i get below message. I have attached a screenshot. What am i doing wrong?

Did you follow the instructions from the other post? I may be best to make one single post to answer all questions.
