Hi,All,
my DELL Latitude CPX Laptop with XP Pro + SP2 . my network(wireless & wired) worked fine until the university changes its wireless setting. I followed the instruction ( I am using a USB wireless adaptor), it works in and out. finally someone in the campus tech support did something to my labtop and it starts to work for a week. then died for ever-- cann't connedted at all.

now, even when I try to use WIRED internet, the computer will keep trying to acquire IP address, and finally failed , and shows "it has limited or no connection(the yellow triangel shows up)". so now niether the wired or wirless network works.

in an attempt to bring back my wired internet ( I already give up on the wireless), I removed the wireless adaptor program ( the source of nightmare, I believe), and restalled my USB LAN adatopr ( old laptop doesn't have a network card inside). it still not working. then I rsinstalled XP Pro in the "repair" mode. but it still shows the same problem.

so anyone could feed me some idea: what is wrong?

by the way, I run a "ipconfig/all" with the LAN adaptor. and the results is uploade to my yahoo album:

The first thing I would check is to make sure that your network connections are setup for DHCP. If the tech guy entered static addresses and then for some reason the gateway changed, you wouldn't be able to connect. Not to mention if your address is statically entered and someone else gets that address via DHCP, you would have an IP conflict.

To check these settings go to my network places, view network connections, right click on the connect, and go to properties. Double click the Internet Protocol (TCP/IP) item. Then make sure that obtain ip address automatically is selected, as well as obtain dns servers addresses automatically. Please note that this will only work if you are behind a router or server that is using DHCP. But that is a very high chance. Try that and post back.
