It sounds like faulty networking equipment, maybe the FreeBSD machine's internal NIC? If the switch is off, does "ifconfig" output still say "status: active", or "status: no carrier"? However, you should be able to restart the network without a reboot, using the following command (as root): # service netif restart What manufacturer is the NIC? Maybe Realtek? I once had a similar problem with a Realtek NIC: After re-connecting, it did still insist on "no carrier", but after "service netif restart", it worked again... :-) -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
