What version of NOOBS Installer /Chooser was on the SD Card ?

Did you install Raspbian from NOOBS ?

I got it from pi hut.
Openelec does not work it just sits there with black screen.

Noobs v1.7 - Built Feb 9 2016

It does say that the oses are not compatible with the version of pi that i have.

Not sure what version of Raspbian is though as i havent found a version detail for that.

There is a newer NOOBS release:

Ok the latest noobs enabled the wifi.
I use channel 13 but the rpi does not see the higher channels.

I found this page where people have the same fault but running updates fixed the issue.

I tried this and it makes the rpi hang on boot

This does not work. if my wifi is on channel 13 the rpi locks out and wont do anything. If i change my wifi to channel 8 it works fine and connects fine but i use channel 13 for everything else on 2G

I am unsure if this relevant but from the Raspbian release notes:

2016-02-26:
* Support added for Pi 3, including Wifi and Bluetooth
* Option to set wifi country code added to raspi-config

I downloaded the latest version.
They mention doing the rpi-update but that causes mine to hang on boot

rpi-update should never be undertaken, unless advised to do so to fix a specific issue ;)

With latest Raspbian Jessie installed, all that is needed is update and dist-upgrade...

If installed without using NOBS installer then the first task is expand file system and reboot ;)

Obviously something is pear shaped.

I got my RPi 3B Wednesday, created a SD Card with the latest Standalone Raspbian Jessie, the WiFi scanned without user intervention, found my Router SSID, put in WPA code etcetera no issues what so ever.

Though I have to admit have little experience of NOOBS Installer...... ;)

It is possible that the rpi-update doesn't play nicely with NOOBS, either because of the way it does the update or because of the content of the update. If you wait a while I think the changes should make their way out to the OS images and upgrades. (dist-upgrade possibly.)

Note that to get the extra channels you also need to configure the WiFi internationalisation in raspi-config. But if your Pi is hanging on boot, that's of little immediate help. The reason is that some countries, USA being the main one, don't permit those extra channels to be used. So the initial configuration, with no country defined, doesn't allow them.

Of course, because you have to tell all your equipment to use them and lots of people don't bother, they tend to be good to use because they are nice and quiet.

If you have an Android phone, install "Wifi Analyser". It draws a nice graph of all the WiFi signals around you and lets you pick the channel with the least contention. IIRC, there is no iPhone version because Apple stopped allowing the apps to access the signal strength of other networks.

Yes rpi-update breaks latest Jessie on 3B - any news on this ?? I'm sure there's work going on to fix this , maybe just advise 'players' to avoid RIP- update for now :lol:

as stated everywhere, rpi-update has not been recommended update/upgrade path since the RP1 1B+, so I am at a loss why that is being pushed, I only recommend rpi-update when I know it is required as is the case for Raspbian Wheezy Standalone. I have no experience what funky stuff happens with NOOBS and frankly not really interested.

rpi-update is required to get the optional WiFi channels working . Not only that, but what I assume is the bleeding edge development build you get by setting BRANCH to "next". Unless you need to use the extra channels and are willing to put up with development-grade software (ie pre-alpha) then using rpi-update is best avoided.

@ JarJarGeek, are you sure it is Jessie that breaks, or are you using NOOBS? It works fine for me using the 2016-02-26 Jessie (Full version.)

Yes rpi-update is being recommended by someone who knows, but it is quite often being used unnecessarily by the uninformed :o

Yes I am using standalone Jessie downloaded yesterday - tried twice rpi-update - NOGO !! 3B freezes hallway through boot -so just stuck with dist-upgrade for now with Wifi UK settings. Wifi is flaky as hell with frequent dropouts - not to keen on trying another rpi-update ; wasting time on burning SD cards !! Also where are the Bluetooth settings / panel hidden ?? Thanks for your help folks

Have you tried switching off power management? That improves throughput on all Pi 3s and is reported as solving the flakiness issues some people have.

Bluetooth is discussed in TWO recent threads:

viewtopic.php?f=28&t=138307

...though using the CLi bluetoothctl seems to be the best solution ;)

think I've cracked it - fingers crossed - do sudo nano /etc/network/interfaces
change ANYTHING saying 'manual' to 'dhcp' like below:


# interfaces(5) file used by ifup(8) and ifdown(8)

# Please note that this file is written to be used with dhcpcd
# For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf'

# Include files from /etc/network/interfaces.d:
source-directory /etc/network/interfaces.d

auto lo
iface lo inet loopback
iface eth0 inet dhcp

allow-hotplug wlan0
iface wlan0 inet dhcp
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
