I had symptoms of what may be the same bug on a different machine, an Ergo
Vista 621 https://forums.pcbsd.org/thread-20235.html and in this case, the GUI
to the Wi-Fi adapter was: 

* present with 11.0-CURRENTOCT2015 updated from an earlier version of the OS

* not present with a clean installation of 11.0-CURRENTOCT2015

Following advice from LooX in irc://chat.freenode.net/#pcbsd I added a line to 
/etc/rc.conf

wlans_wpi0="wlan0"

– then a restart of the OS, and then Wi-Fi was configurable. 

Now:

Apologies: I no longer work in the area where the Toshiba notebooks were
stored, and I suspect that other users' requirements would have led to writing
over the installations of PC-BSD.

If I do find myself with an affected notebook, again, I'll add another comment.

Hi Graham,
Have you had a chance to look into this yet to see if your wireless devices are
correctly shown in "sysctl net.wlan.devices"?
Thanks,
Ben

I am not convinced that is actually a regression in current. I believe it could
be the result of a recent change in current to make it such that wireless
"parent interfaces" are no longer listed in the output of ifconfig(8), but
instead they are listed in the output of "sysctl net.wlan.devices". Other than
that there is no change to the configuration required to bring up wireless
devices. We are waiting on the bug reporter to confirm this is the case, and
that there is no regression.

The change that brought this difference in behaviour was committed to current
on 20150827 in r287197:
https://svnweb.freebsd.org/base?view=revision&revision=287197

It may be that the PC-BSD tools have not yet been updated to reflect this
change in current when running the PC-BSD EDGE branch.

Copying in Kris Moore from PC-BSD in case he has any comment on the PC-BSD
tools.(In reply to Ben Lavery from comment #5)

To add…

I’m running 11.0-CURRENTSEPT2015 (PC-BSD) on a Lenovo ThinkPad T440 with an
Intel 7260ac.

Here is some sample output:
# sysctl net.wlan.devices
net.wlan.devices:
# cd /boot/kernel
# kldload iwm7260fw.ko
# kldload if_iwm.ko
# sysctl net.wlan.devices
net.wlan.devices: iwm0

Only my ethernet (em0) is present in “PC-BSD Network Manager”.  The only
devices shown with `ifconfig -a` are em0 and lo0.
This thread shows more of my setup and is what lead me to this bug report:

Thanks for the hint. I'm away from the Toshiba computers for a few days, out of
town. Aiming to review this report in around a week.

Do you see your lost device in the output of sysctl net.wlan.devices?

No kernel panic. 

The OS simply behaves as if there's no Wi-Fi hardware. 

It'll be a few hours before I can regain access to any of the affected Toshiba
notebooks and then change branch up to 11.0-CURRENTSEPT2015. 

Will it be useful to get PC-BSD diagnostic files before and after the change of
branch? 

Any other hints for before and after the change?

Hi,

I need more information than this. Can you post more of the kernel panic? Can
you get a kernel corefile or the dumpfile in /var/crash/XXX.core.txt (the text
file!) with all the relevant information?

Thanks!

[bugzilla-noreply]

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=203271

Bug ID: 203271
   Summary: Wi-Fi no longer driven on some hardware with
11.0-CURRENT
   Product: Base System
   Version: 11.0-CURRENT
  Hardware: Any
OS: Any
Status: New
  Severity: Affects Some People
  Priority: ---
 Component: wireless
  Assignee: freebsd-wireless@FreeBSD.org
  Reporter: grahamper...@gmail.com

Originally reported as https://bugs.pcbsd.org/issues/11598 then I was advised
that the problem is not specific to PC-BSD. 

Affected hardware includes Toshiba Satellite Pro C50-A-1E6 (part
PSCG7E-02D042EN).
https://forums.pcbsd.org/thread-20234-post-111879.html#pid111879 notes that a
change of branch, down to 10.2-RELEASE, allowed all affected computers to
recognise the Wi-Fi hardware.
