My WZR-G300-NH router (connected to internet) LAN side IP is not 192.168.11.1 but 192.168.x.1 instead. I found that the IP of WCR-GN under bridge mode is always 192.168.11.100....
it seems that they are not able to talk each other.....
I don't want to change my WZR-G300-NH setting as i have put lot of port forwarding into it...
