I got the wireless working using a static IP and after a couple
of reboots it all goes funny - the static IP is dropped and a
DHCP taken from my router. And then that is dropped and
169.254.10.5 appears from nowhere and sits happily but useless
on wlan0. I reconfigure and after a couple of reboots 169..
comes back.
I am getting really pissed off with ubuntu as they've done
something 'clever' but not seemingly, given the tools to sort it
when it goes wrong, or document it.
/etc/network/interfaces seems to be ignored completely and
/etc/network/if-up.d has a varying set of files in it ...
Any clues anyone

This probably doesn't help but....
"If a DHCP server is not available, Ubuntu will attempt to set
up a network automatically using the Zeroconf (or Zero
Configuration Networking). In other words, if a bunch of
computers plug into a hub or router on an ad hoc basis, without
being configured and without a DHCP server operating, they will
be able to network with each other. To make this work, each
computer randomly assigns itself a unique IP address that starts
with 169.254 with a subnet mask of 255.255.0.0."
Maybe an issue with DHCP?
Gibbs
But why does it tear down the static IP configuration (which was
working fine) and then try DHCP and then give up?
Its really strange cos it works and then fluffs up and the other 3/4
machines (one of which uses the same USB wireless) all work happily
now??
