So I upgraded to a 802.11n wireless router (DIR-655) and decided to make it dedicated N instead of trying to serve G and N mixed; to serve G I set up my old WRT54GS router as an AP off of a different IP than the main router.

I see the WRT54GS on the network; wireless status shows it as working; however I can't see the SSID from any of my wireless cards. The only changes I made from when it was working fine before were:

1) Changed the IP (to be different from the new main router IP)
2) Turned of DHCP server (changed from Server to Forwarder and pointed to main router IP)
3) Plugged a network cable into one of the LAN ports (nothing is plugged into the WAN port now)

Wireless status shows everything looks good:
RadioRadio is On
Mode AP
NetworkG-Only
SSID ABCD
Channel 14
Xmit 28 mW
Rate 11 Mbps
Encryption Enabled, WPA Pre-shared Key
PPTP StatusDisconnected

Any idea why this router isn't visible for wireless?
