[ubuntu-nz] Just upgraded and having wireless problems

[Dave Lane]

Hi Tim,

Is the kernel module for your wireless device still supplied in the
default kernel - I seem to recall a minor kernel regression that meant a
few wireless chipsets lost support, but I think an update has been
released...

I had some problems with eth0 after the upgrade (instead NetworkManager
always defaults to starting up my usb0 network device that's used to
talk to my NeoFreerunner phone...), but would probably suggest sticking
with NM...  Now I just have to explicitly tell NM to connect eth0 when I
plug it in (rather than having it do it automatically), not a biggie.
It's also now possible to have both wireless and eth0 (and usb0 for that
matter) connected simultaneously, which is very handy in some
circumstances...

I found that during the upgrade, the NM upgrade script commented out my
wlan0 definition in /etc/network/interfaces, e.g.

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
#auto eth0
#iface eth0 inet dhcp

# The primary wireless interface
#auto wlan0
#iface wlan0 inet dhcp

My understanding is that any network devices that you want NM to manage
should be commented out, and then defined within NM's interface.

My wireless has been working very well since the upgrade, and seems to
connect automatically to whatever my preferred wireless device is,
assuming that the credentials are stored (which it seems to do reliably).

Hope that helps a bit...

Dave
