I have a model Nighthawk X10 and Nighthawk X65 Model EX8000 I can not get extender to hookup

[bhery1110]

I have just had this problem since I updated my firm ware and software.  I tried to connect and I get the message to look for the net 65ext.  I do not show that.  I have unpluged both the router, modem and extendern and ten restarting first the modem then the router then the extender.  that did not do any good. I am lost and not a IT person or have any experience.  can anyone suggest what to do.

do you have the EX8000 setup as a mesh device? 

If so, it uses the same ssid as the router and you won't see a "ext" device. 

Maybe after the update, it got switched to mesh mode (onessid is what its called)

What are all the led's on the ex8000 showing?
