Hi,

Can you give us more informations about the network card / chips ?
Did you found any error in /var/log/ ?

They all work (ping good to all four routers); the Cisco on em3 shows happy lights. I then booted back into FreeBSD, the problem with em3 remains. I have not had any success searching with Google; I may not have used suitable search terms.
