That busted my networking. I did: kldload if_lagg ifconfig lagg0 create ifconfig lagg0 lagproto failover lagport bfe0 lagport wpi0 192.168.1.1 netmask 255.255.255.0 Now when I ping 192.168.1.1, I get a "device busy" messages from ping. Oops. I think I need to reboot to clear this up. -j On Sat, Mar 28, 2009 at 9:35 AM, Sam Leffler <sam@freebsd.org> wrote: > J.
