I have a RE315 that I just reconfigured as a access point. When I connected via Tether to the RE315, I was prompted for a new password (and to re-enter the password). This was not the same as the password I chose for the router (thought it could have been). I changed it to AP mode and rebooted. Was now able to connect to the AP, there was a default SSID, and I was not prompted for a password. 

When I looked in the extender confing in Tether, under the security option it said "no password". The other option is "encrypted". When I select "encrypted" the option changes from "no password"  to "password", but there is no where to enter the password.

 How do I make the login password on the AP the same as the router? Where do I enter the wifi password for the AP? Is this the same as the password to access the AP/Extender? This is very confusing.

The way this should work. - When adding an AP, make the default password the same as the WiFi password for the router. It would be even better if I could use the same SSID everywhere (router and AP) and it would just work. Bonus points for being able to change the WiFi password in one place.

Thanks,

Tom
