thanks for your replies,but I still can not access web admin page.where is it?My lan card can't get IP from my FON,but my wireless card get an IP 10.146.168.99 from lurgo-mesh-37544.What to do next?
If your Fonera is connected to a network that has a DHCP server, then it will get an IP from your LAN, and you too. If it is acting as a Client node (no Internet connectiong atached to it) and there is no DHCP atached either, you can connect to the LAN port and get an IP from the DHCP server running in the Fonera (which also has a DHCP server running in the Private and Public AP).
In any case you can connect to the Private AP, in your case it will be lugro-secure-37544, and enter the IP 10.146.168.129 (which should be the IP of the Private AP of your Fonera) and then a prompt to enter the user "admin" and password "lugro-mesh" will appear.
