The network connection timed out

Question

i am trying to download an ipod software update on a 56k modem, the update gets about one third done and then a message pops up stating that the network connection has timed out and i need to check my network settings. Also when i run network diagnostics on itunes MOST of the time they will come back with "itunes connection status failed" but sometimes (vary rarely) everything will be fine and the store will connect successfully. i tried all the other suggestions from other posts but nothing is working, please help ive been at this for about 2 weeks and im beggining to loose sleep over it!!
here are the diagnostics from when the service cannot connect -
