I've hit a breakthrough on this.
Once I removed the proprietary 'Broadcom STA ...' driver this issue was
resolved.
So this isn't about kernels. And I did confirm this by testing some
kernels.
This is about the presence of the proprietary driver that breaks support
for the card.
Once I uninstalled it using the 'Software Sources' I had my interface
back.
So there are two issues here. One is that the proprietary driver doesn't
work. At least not in quantal for this card.
The other issue is that this proprietary driver was installed
automatically in one of the quantal updates at one point. I didn't call
for it, IIRC. And it would make sense that if I would have installed it
by myself I would have remembered that I had and would have reverted
back once I had no WiFi.
Thanks,
Shahar
** Description changed:
Interface is not created.
-
- Tested using Linux from upstream kernel archive:
- linux-image-3.5.0-030500-generic 3.5.0-030500.201207211835
i386
Wifi worked perfectly in precise and also in quantal until some recent
upgrades.
+
+ It was discovered that the proprietary driver was in use. This seems to
+ have nothing to do with kernels. Once the proprietary driver was removed
+ - the Wifi was fine.
Blessings,
Shahar
