network connection

[Darryl Tidd]

I am having trouble with my network connection.  I am on a network at 
work, and when I am downloading files, the network activity spikes and 
then drops off.  The download then times out.  If downloading multiple 
files, it will do this throughout the entire time.  Sometimes, it works 
like it should and downloads from beginning to end, but most times it 
spikes up and drops off.
Any help or suggestions would be appreciated
