Comment 59 for bug 19740

I think i am having the same problem. I am using Dapper with wireless.

My work around was to add pre-up delay to interfaces file. e.g.

auto eth1
iface eth1 inet dhcp
 wireless-mode managed
 wireless-essid zbo
 wireless-key1 xxxxxxxx
 wireless-key xxxxxxxx
        pre-up sleep 10

Because it is parellizing(?) it does not affect my boot up time. Of course, if i run it later from a terminal i'll have to wait 10s.
