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!

Hi Andrew are you using the normal "network" or are you using "Network Manager"?
