Did you leave something out?  The lsmod showed that you already had
bcm43xx-mac80211 loaded ('-' == '_' for lsmod), and you already had
eth1 marked up and with an IP address assigned.  I can't think of
any reason why those commands should make any difference.

Is this repeatable?  Did you move the laptop during this process?

It's repeatable. I found I did not need to do the 'modprobe bcm43xx-mac80211', just the 'ifup eth1' to get the network working. It seems like some kind of timing problem, like ifcfg-eth1 is getting run before the bcm43xx-mac80211 module has made eth1 the network interface. If eth1 were a wired network interface, it would be like I forgot to plug in the ethernet cable. Does that make any sense or help describe the problem?

Thanks!

Andrew
