My Power Mac G5 hangs when my Ethernet internet connetion is active

Question

I'm having a very weird problem with my computer. When the Ethernet connection to my router is active the computer hang in very basic operations. for example like going back to the log in window, switching from one user to another and connecting to my share files in my windows base computer.Like i said it only happen when the Ethernet cable is connected to my router or Cable Modem and the internet connection is active. I know this because when the computer is not responding I have unplugged the cable off the router and the computer respond right away. The computer was working fine until I decided to move it from one part of the room to another and had to disconnect all the cables. I using a Linksys wireless-b broadband router for the network.
This is the Setting for the connection:
location = automatic
using DHCP
I got personal file sharing, window sharing and printer sharing on.
Please somebody help me this is very annoying
Thanks

Click on the icon on the Finder's sidebar with the house icon and then open the folder Library inside, followed by Preferences and then rename the ByHost folder inside. If the issue persists, open the Terminal application in the /Applications/Utilities/ folder and run the following:
sudo mv /private/var/root/Library/Preferences/ByHost/ /private/var/root/Library/Preferences/ByHost_old/
This command will prompt you for your administrator password; nothing will appear on the screen while you are typing it. Files in the ByHost folders contain your computer's MAC address as part of the name, and are only consulted if your computer's MAC address matches the string in the name.
