Since yesterday's updates, the behaviour has changed a little - I still have no network connection on boot (and the essid is not set). But now, when I run

$ sudo /etc/init.d/networking restart

it does set the essid and start the network properly. So only one command to run each time I start my computer ... While this is an inconvenience for me (as I know the command line well) it could be a show stopper for others - so I think the priority should be increased.

I am confident it is not my DHCP server - it worked fine for me while I was using hoary, warty, breezy, dapper and edgy ... As soon as iwconfig reports that wlan0 has the essid set, dhclient works fine.

I did notice this section in /var/log/messages about 2 minutes after the boot - this may have been when I was running /etc/init.d/networking restart
