N300 EX2700

[RadioSilence]

I've changed my broadband supplier so have a new router.  How do I delete the extender's old router password and change it to the new one? I know the old password but obviously that network no longer exists.  I'm using a Macbook Pro.

i would start over from factory and do a clean install. 

Push and hold reset on it for 7-15 seconds while its powered on. 

Then follow the install guide.
