changing extender names

[StevenJones]

Once set up how do you change the Extender Name used on the Nighthawk Model 7700. As I have two extenders they are interfering with each other using the same extender name.

Thanks

You'd simply log into the extender you wanted to change the name on and turn off "onessid". Then you'd be able to change the ssid.

How close are the extenders? 

are they set up daisy chained or star configuration?
star:  extender<------router------>extender

daisy chain: router------>extender-------->extender
