G5 network connection fails"other application changed"?

[Magkmustang]

Ok, I have: Power PC G5 dual 2.3 w 10.4.11 os,
Lost Internet connection. (ethernet cable direct to router), No known cause. Checked router,cable etc. All work fine w other computers etc.
router does not "see/read" when cable connected to G5.
I figured Ethernet card is dead. Can't afford new card figured I'd try :

Net gear G54 wireless USB adapter, just to get back online.
Downloaded driver for Mac etc.

Went to System Prefernces to set up.
Opened System Preferences then Network,
Automatically this message drops down: "Your network settings have been changed by another application"
When I click "ok" same message automatically drops back down.
Cannot access "Network settings" at all......PLEASE HELP!

This was a bug in one of the updates to Tiger. Just google "Your network settings have been changed by another application" and you'll find plenty of forum links on how to solve it. If I remember right, you can temporarily access your network preferences by ticking one of the check boxes in System Preferences --> Security, and a permanent solution is to remove a couple of preference files from /Library/Preferences/SystemConfiguration.
