Wired Internet Not Connecting

Hey guys,

For whatever reason, as of Tuesday afternoon my laptop can no longer connect to wired internet. I am a college student (NYU), so I cannot access a modem or router myself. I have tried:
-Plugging my cord into another jack in my dorm room
-Using my roommate's ethernet cord
-Taking my cord and laptop to different areas on campus (library, other dorms, etc) that use different wired networks, and attempted connection there

Worth noting is that I can still connect to wireless internet just fine (however, my dorm does not have wireless, making things very difficult for me).

Also worth noting is that it appears to connect to the network, but with "Limited or no connectivity." I cannot connect to the internet at all.

My ethernet adapter is a Realtek PCIe GBE Family Controller. It was just updated today, in hopes that maybe it was a driver issue (Prior, it was a Realtek 8168C/8111C, whatever that means). All drivers have green checks next to them and appear to be working. Here is my IPConfig info:

Description : Realtek PCIe GBE Family Controller
Physical Address : 00-1E-EC-55-91-1F
DHCP Enabled : Yes
Autoconfiguration Enabled : Yes
Autoconfiguration IP Address : 169.254.26.193
Subnet Mask : 255.255.0.0
Default Gateway : (blank)

I am running Windows XP Service Pack 3. My laptop is a custom-built CyberPower PC. I have done a Malwarebytes Scan, SuperAntiSpyware Scan, and Avast Anti-Virus scan, and have turned up no malware or viruses. Any help would be greatly appreciated.

what firewall do you have on the PC that maybe blocking

First - try a TCP/IP reset - see below
second - try in safemode with networking - as the PC starts keep tapping F8 - a menu appears choose safemode with networking see if it connects via ethernet now

It may be avast - had that before with antivirus - so make a NOTE of the KEY you are using on avast and you could uninstall and re-install

Since you are able to connect using wireless, but not with wired, if I were you I would have checked with Network Administrator first
