you would be surfing at the speed of light - I think you meant to type 1Mb.
You say that this problem started when you "tried to set up a network", but you don't say what happened - did you succeed, or did the setup attempt fail? Do both computers share the broadband connection? I assume they do, and I wonder what happens when you disconnect the second machine - does your upload speed return to normal? I presume you can surf the web normally?
Problems with site uploads do occur - from time to time some servers decide to go slow - but 8 minutes for one page file is stretching things a bit too far. Post back with the answers to my questions, and any more information you feel might be of use, and some of us will try to help.
