Wireless printer says no connection found , using linksy router

I bought a Linksys Wireless-G WPS54G printer server and trie to put it in my home network. Following the instruction from the manufacturer and spent many hours, I still couldn't make the printer server work. There was no problem to get the IP address from my DHCP server using the wired connection. But when I pulled off the network cable and tried the wireless connection, I got "connection failed" error at the last step to install the printer server. I checked my router's client monitor and found the printer server did get the dynamic IP address wirelessly. When I pinged that IP address, there was no response at all from the printer server. In another word, the printer server couldn't communicate with other devices in wireless mode in the network. I searched the Internet and found there were many users had same problem and couldn't resolve the issue even from the manufacturer technical support. As a last resort before I was going to send back the printer server, I switched the network router to one of a different brand. My previous router was manufactured by BUFALLO INC and the new one was made by D-Link. After I rerun the installation following the instruction, the "connection failed" error was gone. The printer server could work finally.

The tip here is: Try a different brand router when there is a connection failure problem for installing the WPS54G printer server, if possible.
