I put this thing into range extender mode. Logged into it, chose the AP i wanted and when I went to set it up, I keep getting the Invalid Bridge BSSID. What is it supposed to be? Is it the wifi ap I a

When I try to set it up for AP extender mode, I still only have wireless mode or 3/4g mode. Thats it. The only mode I have is if it is plugged into a router and i can log into it, so just a wifi route
