losing connection when updating a game

final fantasy xi wont update on my internet connection, however on my parents(a different ISP) it will. On my connection, the update client starts to update and then gives an error saying its connection was lost. I've had this same problem with this ISP(internet USA) in the past. Any ideas on what it could be and how to fix it?

 

you can't fix it if is your provider fault

if you're using the onboard lan you may try a pci lan card just to be sure that is the isp fault;if the same problems occur than is clearly their fault if not is the onboard lan fault.
