I recently bought a 13" MBP and took the opportunity to upgrade my AirPort Extreme to the shiny new dual network version. It's all set up and, more or less, working with simultaneous backwards-compatible and pure-N (5ghz) networks.
However, I keep getting a very strange problem that particularly occurs with my partners late 2007 MacBook Pro where the AirPort Extreme will think it's assigned an IP address to a client, however that client will have a self-assigned IP and, thus, is unable to get online.
Has anyone else experienced and, more importantly, managed to fix this quirk of the new AirPort Extreme? Could mine be a dud? Could fairies be eating the DHCP packets?
Question about
Odd IP Address Assignments
On the machine that seems to be hanging on to a bad ip:
From terminal release the ip address fro the wireless adaptor. (usually en1 for wireless, en0 for wired)
$>ifconfig en1 down
$>ifconfig en1 up
Also to avoid IP conflicts with stubborn devices you'll probably want to assign DHCP Reservations (for a range of address within your subnet) to some or all of your machines. Open Airport Utility->Manual Setup->Click "Internet" ->"DHCP"
So although DHCP is the method, the only IPs dynamically assigned are those belonging to my guests.

Thanks for your response.
Is using ifconfig not functionally equivalent to using "Turn Airport Off"?
I've slowly started adding DHCP reservations for devices now, to see if it'll help. I also enabled guest network functionality as a fall back... it's a long shot, but as it assigns from a different IP pool and appears as a different network it might work as a backup solution if any system plays up again.
