I tried going to ITS for help, but got nowhere.  My ticket is below.  
Let me summarize the problem first though.

Since August my wireless has worked.  My laptop has never had anything 
but Ubuntu on it.  My wireless still works at my house, and, more 
importantly, at 208 West Franklin St, on UNC-1.  In Manning Hall, my 
wireless does not work.  For details, see below, or ask me questions.

Thanks so much for your help!

The change notice doesn't say when the problem started. I was having 
problems for the first time yesterday (1/14) at 10:30am. The change 
notice was released today at 6:26. Additionally, how do they define 
"DHCP registration"? I've long had my MAC address registered, if that's 
what they mean. I'm willing to believe that's the correct problem, by 
why did it take so long to figure out and why are other people not 
having problems with wireless?

Douglas,

It is possible that this ITS Change notice is responsible; your wireless 
card is registered and receiving a 169 IP address as if it is not.

You will need to delete any current configurations for the wireless 
networks you are attempting to connect to (UNC-1 since it is not working):

1) Delete current wireless networks: Go to Start --> Run --> and type:

NCPA.CPL

to open the Network Connections window. Right-click the "Wireless 
Network Connection" to reveal a context menu. Click "Properties", then 
click the "Wireless Networks" tab to view all currently configured 
wireless networks. Select any networks in the list that you cannot 
connect to and click "Remove" to remove them. After doing so...(please 
leave this window open for the next step)

2) Follow the directions found at http://help.unc.edu/4977 .

Hope this helps!

If I can answer any more questions or help you further, please reply to 
this email.

Unfortunately, the Change notice appears to be taken care of. However, I 
am still having problems. I restarted my network card with

sudo NetworkManager restart

However, the issue persists. I use Ubuntu Linux, but since August my 
wireless has worked fine. It still works fine at home and it did earlier 
today on the campus network at 208 West Franklin, the Development Office.

Douglas,

Is today the first time you've tried using wireless with Ubuntu Linux? 
It may be the fact that UNC-1 is not broadcasting that is causing the 
problems. When you return home, try setting your wireless network at 
home to not broadcast and see if you can still connect.

If I can answer any more questions or help you further, please reply to 
this email.

Let me clarify my statement from last time: "I use Ubuntu Linux, but 
since August my wireless has worked fine." What I mean by this is that 
when the semester started and I was on campus daily, I have never had a 
wireless problem until yesterday, Monday January 14th. I am able to 
connect to UNC-1 in other locations on campus, namely, where I work at 
208 Franklin St, even more specifically, in the server room there. I 
have had problems in both 208 Manning (not to be confused with 208 W 
Franklin) and the SILS Lounge here, both of which are on the second 
floor of the building.

Douglas,

My apologies, but my experience with Linux is limited; was there a 
particular support group you had in mind for support with this 
particular issue? If not, you could contact Mark Ingram or Shelly Brown 
for assistance.

If I can answer any more questions or help you further, please reply to 
this email.

Mark and Shelley have no say over Manning, where the problem is 
occuring. I'll send out to the UNC LUG. Thanks though.
