Wga54g wont work with new 1200 router..internet never works but there's a connection

Question

I've tried so many settings I cant even remember where i left off but one general question will help me troubleshoot to the next step.
sometimes the connection shows 'acquring address' but never connects. i've fiddled with things so that i can get the GA to acquire an address but the internet comes through. Also the GA never shows up on the client table.
So is the fact that i can get a network address a good thing or doesnt that necessarily mean i'm 'connected' to the network. Its frustrating to have the G light lite up yet no connection
also at one point i did get the GA to show up in the client table when it was directly connected to the 1200 but when i walked into the room and attached it to the PC, no dice
i've turned off all firewalls temporarily and the 1200 is set on wpa/wp2 mixed. when i tried setting it just to wpa i got a warning then i lost my interenet. i had to reinstall the 1200 again
other misc details in no particular order..just things i've tried
setting MAC and and IP just for the GA.. did 192.168.1.112...did a reservation from the 1200 setup screen
sometimes the 1.250 browswer access to the GA turns off, for instance when i change it to automatically DHCP or when i set the IP to 1.112 i lose the ability to get into the setup.
ive tried setting up the IP in the TCP settings of the connection as 192.168.1.112 but is the gateway necessary? i've tried what i believe to be correct gateways of 192.168.254.1 and 192. 168. 254 254 with no success.
when i do have success getting into the GA setup screen and things say 'connected', i still dont have the internet, just the green light on the adapter.
i have this on infrastructure

First of all try the following steps in the E1200:
A] With the help of Cisco Connect Software (if at all you have installed the router with the help of this software)
1] Open the software and go to the option which says "Router Settings"
2] Then click on the option which says "Advanced Settings" which will take you to the router's configuration page.
3] Then Click on wireless Tab select Channel Width to 20 MHz only and Channel to 6, 9, and 11. Click Save Settings....
B] If you haven't installed Cisco Connect then you can log on to the router's user interface using it's default IP address in the browser which is 192.168.1.1 and type in 'admin' as the password leaving the username field blank. This will take you to the router's web interface and then follow steps as mentioned above to make the changes.
Second the gaming adapter will only show up in the DHCP client table when it is connected directly to the router, other wise it will not appear. Since the gaming adapter has a fixed ip address – 192.168.1.250
Third you have to lower down the Wireless Security level to WEP as this gaming adapter can only accept WEP security...
