Re: WiFi issues after upgrade on Sid, wlan0 ; No such device
My problem was resolved with an `aptitude dist-upgrade` which removed
some obsolete packages and allowed new things to get upgraded,
including a new kernel. I was being cautious with `aptitude upgrade`
and `aptitude safe-upgrade`, but now I see the value of dist-upgrade.

Thanks for the tip. Not sure what this would've looked like before the
dist-upgrade state...but now it's like so:
% lsmod | grep iwlagn
% modinfo iwlagn | grep depends
depends: mac80211,cfg80211
% modinfo iwlagn | grep -A 1 filename
filename: /lib/modules/3.2.0-2-686-pae/kernel/drivers/net/wireless/iwlwifi/iwlwifi.ko
alias: iwlagn
... looks like iwlagn is now an alias to the iwlwifi module, which has
replaced iwlagn as of Linux 3.2. In any case, WiFi is working fine now.

As mentioned above, I'd been neglecting to do a dist-upgrade, so some
old obsolete packages were preventing the install of a new kernel,
only allowing it if 440 packages could be removed. After doing a
`dist-upgrade` i was able to install 3.2.0-2-686-pae with no fuss,
and things are working fine now.

John
