Raspberry Pi 3 Wifi Setup

[fruitoftheloom]

Yesterday I had the same problem and I found, that my router was on channel 13. The actual Jessy release seems to support wifi only up to channel 11. I switched to channel 8 and it worked.

If you update Jessie there is a "fix" for this issuse:

Code: Select all

sudo apt-get update
sudo apt-get dist-upgrade
sudo reboot

[TromboneBernie]

actually I did this updat/upgrade procedure but still couldn't see my wifi on channel 13 ...

[DougieLawson]

I think this is a bug in the CRDA data along with a bug in the kernel driver there's another thread where someone with COUNTRY=DE can't see channel12 or 13.

It worked out the box with jessie from noobs but I had to click the icon on the task bar a few times before it showed my router,then enter psk. It needs a strong signal but streams Kodi video as good as ethernet cable.I heard it works in an aluminium Flirc case but I got a plastic Lego block box to be safe.

I liked the comment "It should just work". I would have to agree. But it doesn't for me, and by the look of it, many others.

I downloaded the latest version of NOOBS and copied the files to a new 32Gb SD. The Pi3 did the install thing, but the icon at the top of the screen doesn't show available networks, just a strange IP address.

Pi3 wifi is the first thing that drops out when the psu isnt quite up to it.

I had a few problems today replacing a B+ setup with a pi3 - same PSU leads and sd card.
B+ had edimax usb dongle.

Pi3 would work on boot for a few mins, then lose wifi. Fixed it by swapping out the PSU USB lead for a shorter one
(PSU is an Anker 5 way USB similar to http://www.amazon.co.uk/Anker-PowerPort ... B00PK1IIJY)

Is there an easy way of checking a usb lead's resistance ?

My Pi 2 has not worked on Wifi since the first release of Jessie. I have changed anything and everything to try to get it to work, but the router steadfastly refused to show up on a search.

The router is a BTHomeHub mk2. On the Wifi setup screen of the router, there is a throwaway remark that setting the channel to 12 or 13 may not work with all devices.

It has been set to channel 13 for years with no problem.

I changed it to channel 8, and the BTHomeHub suddenly appeared when the network icon was clicked. I typed in the passphrase and it now works a treat. Marvellous!

It would appear that the Wheezy driver support channels 12/13 but the Jessie version doesn't. If only I had known this six months ago it would have saved a lot of bad temper and language to match!

I found the solution. The files brcmfmac43430-sdio.txt and brcmfmac43430-sdio.bin where missing in /lib/firmware/brcm.

My WIFI worked correctly for a couple of days, then refused to work.
I checked, the brcm folder was missing (and so all of its content).

I recreated it using

Code: Select all

 cd /lib/firmware/
sudo mkdir brcm

then copy/paste the two files in the new folder (using sudo cp)


When I tried :

Code: Select all

sudo iw dev wlan0 set power_save off
command failed: No such device (-19)

Is there a special command to reinstall the pilotes?

I had the same problem (no Wi-Fi on the Pi-3 after migrating a Raspian SD card from a Pi-2)

I tried many of the suggestions above, but what really helped was:

I just got my Pi 3 and can not get either the WiFi or direct connect to work. The WiFi has been associated with wlan0 and configured (according to the icon in the top right). What else do I need to do??

Problem fixed!!
Thx a lot!!

Hello,
i cannot see any wifi networks scanned by my Pi3 under Rapsbian installed with the Noobs.
In this post i see some solutions, but the last one just above, could you explain how to apply it ? I am not used to Linux so i don't know how to apply this.

Regards,
Bernard

[bemo47]

Ooops, fyi, i did change the channel for my Wifi box which was 12, it is now 11 and the Pi3 detect it immediately....

Never used NOOBS, but try this :

I the LX Terminal, copy paste the following lines

sudo mv brcm* /lib/firmware/brcm/

sudo rpi-update

sudo reboot

the directory didn't exist on my RPi, so I created it with the command (in that case you will have to execute this first):

Code: Select all

cd /lib/firmware/
sudo mkdir brcm

[bemo47]

Ok, good, it works fine now, i am on channel 13 and its ok.

Thks

The two files you mentioned were present in the release, but had different sizes:

• -rw-r--r-- 1 root root 368957 Feb 25 06:47 brcmfmac43430-sdio.bin
  -rw-r--r-- 1 root root 1108 Feb 25 06:47 brcmfmac43430-sdio.txt

Downloading the two from the repository gave me these two:

• -rw-r--r-- 1 root root 32075 Mar 18 15:40 brcmfmac43430-sdio.bin
  -rw-r--r-- 1 root root 45011 Mar 18 15:40 brcmfmac43430-sdio.txt

You downloaded the HTML pages describing the files, not the files themselves! You need the raw versions:

I'm having a similar issue getting WiFi up and running on the Pi 3, but instead of it simply "not working" or just not being able to connect, I'm actually getting kernel panics:

I'm running a headless Jessie Lite (the 2016-03-18 version), connecting over SSH via wired ethernet, and have been following the instructions posted here.

If I reboot after adding my credentials to the `wpa_supplicant.conf` file, I consistently get a panic at around 50 seconds: https://gist.github.com/rknLA/1c700422c ... 9405712848

I also get basically the same thing after editing the file and trying to restart wpa_supplicant: https://gist.github.com/rknLA/50c1d24cb ... c79eee0b32


The wifi router is running 802.11n at 5GHz, on channel 48, and I am also in Germany, so I had changed the "GB" in the conf file to "DE" as well..

Has everyone else here been seeing kernel "Oops"es like this, or is it "just not working" for you?

[dgordon42]

@rkn,
Did you expand the file system using raspi-config after installing Jessie Lite?
It's a necessary step, but I don't see it in the instructions you referenced.

Also, it's usually better to open a new thread for a new problem. If you have already expanded your file system, I would recommend you open a new thread.

Hope this helps,
Dave.

Is there a possibility to add an external - more powerful antenna to the internal wifi on rpi3.
I noticed that the reach of the internal wifi is very sensitive to the powersupply of the rpi and voltage drops cause unpredictable behavior.

It's been done.

Whether it breaches the FCC certification is uncertain.

Hi,

I've some problems with my RPi3.

They can't see my Wifi SSID.

I've found the problem, it was the chanels from my wifi's antenna.

The RPi3 don't support wifi chanel above 11.

The 4 antennas i've at home, only 1 was visible.

Is it a kernel problem, or a limitation on the Pi3?

Thanks

(Sorry, i have a bad english)

[badnexus]

Had the same thing. Hope they will fix this soon. At my university they are using high channels. Also WPA2-Enterprise doesnt work.

[texy]

The Pi 3 does support channels up to 13. On the initial Pi 3 Raspbian OS it did not, but subsequent releases did, or alternatively update the system.

On my raspberry PI 3 I have 2016-05-10 Raspbian Jessie Lite, and trying to start the access point daemon there are error messages:

Code: Select all

pi@raspberrypi:~ $ sudo /usr/sbin/hostapd /etc/hostapd/hostapd.conf 
Configuration file: /etc/hostapd/hostapd.conf
Failed to create interface mon.wlan0: -95 (Operation not supported)
wlan0: Could not connect to kernel driver
Using interface wlan0 with hwaddr b8:27:eb:16:e4:c7 and ssid "RaspberryPiFi"
wlan0: interface state UNINITIALIZED->ENABLED
wlan0: AP-ENABLED

The two messages above "Failed to create..." and "wlan0: Could not connect to kernel driver" are worrying. Did others experience this, and how did you fix it?

RP3. About 3 weeks out of the box, updated last about 2 weeks ago.

Wifi was working fine (apart from not picking up one of the primary networks, but haven't dug into the reasons for that yet so could be a multitude of reasons) up until about a 4 days ago when I couldn't get it to connect to the local network. We have 2 networks close enough for us to see a weak signal from network 1 (N1) when in the region for N2. I was originally using the rp3 in the area for N2, not seeing it, but able to connect to N1. Now I'm actually in the region for N1, apparently connecting (according to the wifi icon & the fact it asks for the password occasionally), but not able to browse the net, update Raspbian or any such thing.

The brcm folder is present and fully stocked (as far as I can tell), have checked networks via terminal and everything seems to be the same as when I started using the rp3. I've been searching through all the forums I can find to work this out, I'm reasonably technically competent (so can follow instructions), but a bit of a noob when it comes to programming, linux, & using terminal (that's why I bought the rp in the first place).

Any help much appreciated.

Cheers
