Check out you networking stack. Like NIC Card settings with ethtool and
your dns like namserver settings in resolve.conf. If it is getting an
address by dhcp sometimes it want pull in the actual real dns servers.
All will get is like a 192.168.0.x from the modem/router. Ifconfig ethX
will show you the amount of packets dropped also. Possibly a driver
issue with your nic? Could be many things you just have to go step by
step...
