And which one are you using while seeing this ?

Can you check /etc/hosts and or post it here; I saw similar things when 
I accidently removed my machine host name from /etc/hosts ? Or maybe it 
doesn't have the localhost entry and net stuff is timing out.
ping localhost
ping {machine host name}
ping {gateway}

Second guess, that I have noted with win machines at the office - every 
now and then win will set the netcard link to 100/Full or alternatively 
to Auto, when it needs to be the other way (for win to boot properly - 
depends on net card). This makes everything on the machine run really 
slowly (opening any app - which tries to reference network printers, 
because the card then communicates at 10/half, but in short responses  - 
and never gets more than 100 Bytes/sec etc). I have never seen this on 
Fedora, though.
