Been there and experienced many show stopping issues.
Is I pointed out - one has to read the mail to see there are few "gotcha" which points to so far unsolved basic problems with latest release of Ubuntu WiFi.

The "problem" is , IMHO, nobody addresses the basic (WiFi) issue and people post hacks to solve THEIR issue only.
"solutions " like "remove battery and reinstall it" , reboot , reinstall etc do not solve this.
I can do

pi@piUnsure | :~ $ ifconfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 10.0.1.38 netmask 255.255.255.0 broadcast 10.0.1.255

RX errors 0 dropped 0 overruns 0 frame 0
TX packets 420 bytes 95606 (93.3 KiB)

My "problem " is - I have TWO wlan interfaces - RPI and Belkin.
So I unplug the belkin and plug it back

Here is ifconfig AFTER

See "the issue " ?

Why did the OS missed the USB Wifi on first ifconfig?
Or did it missed RPi interface?

And this is just one example of how this goofy WiFi behavior is being "troubleshooted " by unsubstantiated suggestions - "try this...".


Sorry for the long vent.


Cheers Vaclav
