And thats plenty for my static IP system at home
The problem is if you still use the same resolv.conf and hosts at school as
you do at home. Lets say the school network doesn't find the relevant DNS
servers, it may slow things down. Also if the name given by the school DHCP
conflicts with your resolv.conf it might slow things down.
I would check the DHCP settings.
all in /etc/sysconfig/network/dhcp
also check /etc/sysconfig/network/ifcfg-* to make sure everyting looks ok.
