WN3000RP won't connect to internet

[Fitter1]

I just bought a R7800 WIFI Router. Followed all the setups, connected WN3000RP extender. R7800 will access the internet, WN3000RP will not. Both show up as on my network. Factory reset the extender and reinstalled. Still will not connect to internet. Could use some help.

Hello Fitter1

Try changing the wireless channel on the router and make sure you are using WPA2 security.
