Just flashed my fonera with gargoyle (yes...again!

This is what i've done:
1) Installed gargoyle

2) Log in via web interface
3) Configured as Wifi Bridge/Repeater
4) Set ip,subnet,etc... respecting my existing wifi network
5) Connect via Client/Bridge option enabled
6) Repeater disabled
7) ssid & encryption identical to my existing network
8) saved and reboot
The problem is that it never associate with my existing wifi router (there's not mac restiction!, but only wpa2 encryption).
I can ping LaFonera only if i plug the ethernet cable

Any idea?
