Open a command prompt as before and type:
netstat -an | find "ESTABLISHED"
You should get something like:
\Users\Shelly>netstat -an | find "ESTABLISHED"
TCP 127.0.0.1:56457 127.0.0.1:56458 ESTABLISHED
TCP 127.0.0.1:56458 127.0.0.1:56457 ESTABLISHED
TCP 192.168.11.47:61055 74.125.129.17:443 ESTABLISHED
TCP 192.168.11.47:63893 77.234.41.52:80 ESTABLISHED
Try to connect to 74.125.129.113 then click on the up arrow to repeat the command and hit Enter. Do you have any new lines?
netstat -an | find "74.125.129.113"
Does 74.125.129.113 show up in the output?
Let's see if ftp will work to download and install Opera:
I doubt that it's a browser problem but it would be interesting to see if ftp works.
This procedure is a method of downloading and installing an alternate browser when the installed browser does not work.
Start, All Programs, Accessories then Command Prompt. (Win 7 and Vista must Right click on Command Prompt and Run As Admin.)
Bold text is what you type with an Enter after each line. Regular text is the expected response. Text in parentheses are my comments.

Now is the tricky part. Have to find where it got stored. Do a search of the C:\ for Opera and it should show up.
Usually it stores the file in C:\users\YourLoginName\ (Win 7 or Vista) or in XP at C:\Documents and Settings\YourLoginName\
Right click on it and Open File Location then run the file in XP by doubleclicking. (Win 7 or Vista => right click on the the file and Run As Administrator). It installs very quickly. See if it will go anywhere like to att.com
The next step would be to install wireshark
http://www.wireshark.org/and monitor the traffic to see what exactly is happening but I really think it's an ISP/modem problem.
