Public bug reported:
After the last updates I can't connect anymore to WIFI networks, including:
- office wifi (WPA / WPA2 enterprise + PEAP)
- public wifi from airport lounges, hotels, conferences.
The notebook (dell inspiron) still detects the available newtorks. If
they are protected, then additional data are requested (passwords and
the like). So it seems that the wifi card is working well with the
current driver (see below for further evidence). However, then the
connection times out before getting any IP address.
When I switch to Windows, I immediately get the connection (then the
wifi network and the notebook's hardware are OK). Sometimes, when I
switch back to Ubuntu, the connection starts spontaneously and I can
work normally (as if the problem were in the DHCP protocol execution,
and the Windows connection "did some work" that Ubuntu currently can't
do). (further evidence that the driver is OK).
I'm using the proprietary driver proposed by Ubuntu:
"This package contains Broadcom 802.11 Linux STA wireless driver for use with
Broadcom's BCM4311-, BCM4312-, BCM4313-, BCM4321-, BCM4322-, BCM43224-, and
BCM43225-, BCM43227- and BCM43228-based hardware."
