DP-G321 wireless print server no wireless

I am having trouble with a D-Link DP-G321 ver C.1 print server on a home network. Many of my questions are very basic networking questions.
(I use this server to connect an old HP Laserjet 6mp to my newer mac and pc computers.)

My computers (iMac and 2 Dells from work, some items like phones) are networked with a Linksys WRTG54G. The Local IP range for devices are 192.168.5.100 and up via DHCP.
I have WEP security mode.

The G321 has the latest firmware (release 2.10). I can connect and print easily when the G321 is wired to my Linksys.

I set up the G321 to use DHCP - assigned 192.168.5.104.

In the wireless setup page, the G321 sees the Linksys. I can enter the security key. If I choose Infrastructure, I do not get a WAN light on the font indicating a successful connection. If I choose Ad Hoc, I get the WAN light. Simple question - why is this?

The G321 shows the correct SSID, speed, channel, encryption, and shows 'yes' for Link. it shows packet counts of 0. I am not sure if any should show or does that occur only when fully wireless?

I de-powered, unplugged ethernet, re-powered - no connection; no response to pinging.

In the G321 setup pages, I see MAC Rendezvous and "Appletalk Printing" but not sure how these work.
IP Address : 192.168.5.104 (DHCP)

on another page
DHCP/BOOTP:Enable (IP : 192.168.5.104)
UPnP:Enable (IP : 192.168.5.104)
MAC Rendezvous:Enable (IP : 169.254.115.162)



related question, will using DHCP on a print server cause problems with the printer port? or is the port on a different level than the IP connection?
During troubleshooting I changed the G321 to a manual IP address - 192.168.5.109. When looking at the DHCP clients table, the old address for G321 still shows up. I can ping both addresses. Should the G321 connect via two addresses, or is this a violation of having a DHCP router and a connecting device set to manual?

I have since changed the G321 back to DHCP

Thanks,
Ted

Can anyone recommend a forum for this type of question?
