So start simple and turn off the repeater mode device and see if you can get connections to the main router. I guess I thought you were doing something more complex. It appears all you are doing is trying to get a wifi connection on your cell phones.
This should be fairly trivial to get a connection. Not much to setup the SSID and the password and they connect.
If that works then you need to be really sure you have configured the second device correctly. I did not think it could run in repeater mode with the factory firmware. I think you must put the device in the approved list on the main router for it accept the WDS connection from the second. I forget its been a long time since I ran factory firmware, i load merlin on all...
