Raspberry Pi 3, WiFi gone with the wind (but now back).

I dunno… Is it just me, or did the wireless just go away with the latest build of Rasbpian (as of today 2016-08, build from before summer).
Tried it out on two different 3´s – with both the full blown version and the lite one. Did not matter. There’s bluetooth, but no wifi.
The module(s) is loaded – but to no avail.

Been using both ones with the official Pi Screen. Been pondering if there is a bad glitch with not powering stuff separately ( power connected over GPIO ).

I’ll try it out without the interconnect and power them separately…

The whole of the interwebs seems to know nothing about it. What have I done that no one else seems to have noticed?

EDIT/UPDATE:
So … Just reconnected the lab-machine again after having it connected over ethernet, and guess what – the drivers seems to be back, for some odd reason. Odd… Odd.. Odd..

EDIT2/UPDATE2:

Seems to be related to power consumtion.. It’s a bit weird.

Presenting the PiWall and the PiES.

It has been a bumpy ride for the PiWall setup.
Memory-cards dying all over the place kinda killed the first PiWall and a few of the PiES.
The first incarnation of the PiWall held a bridge feature with wireless included with WPA2. Sadly due to stability issues with previous power supply I had to ditch it before – I might rebuild it again now that I have a new fancy supply attached.
I did also loose my nifty compiled squid proxy that made updating less costing bandwith wise (it has to be slim in space, power and bandwith – it´s raspberry pi´s! ).
However, now they are finally in order, and ready to perform all the fun stuff I want.

The main layout goes as follows;
All PiES uses rasbian as base – some the full featured version, and some the lite release. Hardware wise they are Raspberry Pi B, B+ and raspberry pi 2´s.

Top – PiWall – simple firewall gateway with NAT. Uses NTOP for enjoyment over the webs. Featureset includes Gateway (NAT), DHCP,DNS. Will include Squid against attached usb stick on Pi-Blue.
Pi-Blue – the blue cable – for the Pi with the touchscreen that is attatched to the side. Graphs realtime with iftop. Will serve usb stick over NFS for additional r/w features (ie, squid).
Pi-Orange – Master node and will be used as controller for all. Any actions onwards will be directed from this baby.
Pi-Purple – Slave node.
Pi-Yellow – Slave node.
Pi-Green – slave node.
pies-switch – a “smart” netgear switch with a webinterface
On the side – One to many USB “psu”. Makes it easier..

Next step will be to re-compile glusterFS – I had it partially working until two SD-cards died…

I will try to in the future add Partial PXE-boot-like enviroment. Meaning that only data on the SD-card locally will be the needed boot-part – the rest will not reside on it, making the setup more durable and totally minimizing writes to the SD-cards.
