Strange Internet Problems

[Jason Dusek]

In certain places, I am unable to get on the internet even though I am 
recognized by the DHCP server and assigned an IP address. In most cases, I am 
not able to ping anything, but even when I can (for example at my parents' 
house, which is serviced by MSN) my browser times out. What is the name of this 
problem, and which section of the docs will help me to fix it?
