WRT54G AP setup issue

Referencing: http://www.maximumpc.com/forums/viewtopic.php?t=59541

I have tried a couple of times to follow the instructions but I am still unable to properly configure my WRT54G router into an access point plus 4 port router/switch. The goal is to connect my Sony Blu-ray player (BDP-S470) to the internet. I want to place the router next to my Blu-ray player and connect a cat5 cable between the two.

My main router is a Belkin F5D7234-4-BC v1 (ver. 1002).
Firmware Version: F5D7234-4_US_1.00.01
Boot Version: v1.02
IP Address: 192.168.1.1
IP Address range: 192.168.1.2 thru 192.168.1.100
It is currently connected to my PC via cat5 and I am using the wireless (WPA2-Personal and PSK). Overall it is a pretty basic setup.

My Linksys WRT54G v3
Firmware Version: 4.21.1
IP Address: 192.168.1.66

I am using my droid phone (app: wifi analyzer) and I see my new AP. Once I make all the chances in the Linksys I am unable to log back into it to make further changes and so I have to reset the unit. I assume I cannot log back in is because the ports on the router are deactivated. Once I configure the AP I connect it my laptop (via cat5 with wireless off) but the wired connection has an issue. The message states the connection is “Limited or no connectivity”.

Any additional thoughts would be greatly appreciated!

It is imperative that you turn disable the DHCP server in the WRT54. I just set one up as an access point the other day, and I found that you have to do all the other settings first, while the WRT54 is not connected to the rest of the LAN, then disable the DHCP server as the very last setting change, and only then hook it up to the main router (which, of course, needs to have it's DHCP server enabled).

Also, your WRT54G's IP should NOT be in the DHCP pool of the main router. If your range goes to 100, then you could use 192.168.1.101 instead.
