|I guess, you've connected the wired routers WAN port to the Belkin AP LAN port.|
You can do this, but then you have to configure the ISP settings in the Netgear (wired router) to connect via static IP address.
So this static IP address must be a address of the range of the Belkin AP.
Assuming the Belkins internal address is 192.168.0.1, the Netgears IP address should be 192.168.0.2, netmask 255.255.255.0, gateway 192.168.0.1 (from the Belkin) and DNS 192.168.0.1 (also from the Belkin router).
Otherwise, if you woun't configure it as described, you must connect one Netgear LAN port to the Belkin LAN port.
In this case, you don't have to change the IP settings in the Netgear, except both do have the same internal network address. In this case, you have to change the LAN ip address of the Netgear.
Please send a reply, if you solved the problem !!!
