At GRUB boot screen press 'a' on the Fedora entry and type " noapic" and hit enter to boot. It is possible you could have problems with the dynamic IRQs and seeing these problems with heavy network usage. I have heard of APIC causing problems with networking, but this is only a guess. Can you reproduce errors in other ways by using the network? Perhaps downloading a file from the internet (by http, to get away from ftp).
