I have a F5D8230-4 wireless router. I want to hook it up to an
existing LAN and just use it to access that LAN. What I found is:
I can hook it up from a LAN port to the WAN port and access the
internet. HOWEVER, I cannot access a NAS that I have on the LAN nor
can I access the router itself (192.168.0.1)

If I disconect the router from the LAN, I can access the router (yes I
have a password).

I turned off the firewall and allowed remote access to the router but
still no luck.

I think I need to set the router to be an access point but this is all
I can find in the manual about that and I have questions:

"The Router can be configured to work as a wireless
network Access Point. Using this mode will defeat the NAT IP sharing
feature and DHCP server. In AP mode, the Router will need to be
configured with an IP address that is in the same subnet as the
rest of the network that you will bridge to. The default IP address
is 192.168.2.254 and subnet mask is 255.255.255.0."

How do I check the subnet on the other router? If the Belkin router
only allows an IP 192.168.2.* then what do I do if the other router
isn't set for that address? How do I set the other router if, say, its
setting are 192.168.0.1 and mask is 255.255.255.0

HELP!
