Public bug reported:
Binary package hint: linux-restricted-modules-2.6-686-smp
I run Dapper (kernel 2.6.15-686-26) on a MacBook laptop with an Atheros-
based wireless NIC for which the madwifi-ng kernel modules show up
properly in lsmod -- all of them, so this is not the same as bug #46639.
Problem is that the ath0 interface (in my case configured with WEP) is
hard to activate. It isn't working after a reboot, even though the
System-Administration-Networking menu says it is active (but no gateway
shown).
I have found the following convoluted way of making this work (works
100% of the time):
1. Still in the menu, first deactivate ath0, then activate it again;
this will take quite a while, but then show ath0 as activated and as
gateway.
Quitting the menu and "ping -c 4 www.yahoo.com" shows that wireless is
NOT in fact working. Now do
2. "sudo ifup ath0", which after the second DHCP request brings up the
interface.
Doing it any other way, such as through repeated ifdown/ifup commands
does not work.
Although I have listed restricted-modules as the affected package, it may be a
gnome-network-manager thing. Note that the "network-manager" package (and its
associated nm-applet) do not work at all: don't even detect any wireless
networks).
I'm attaching the output of dmesg -- there seems to be an IPv6 issue that I
don't understand.
