Raspberry Pi 3 no wifi

Sat Mar 12, 2016 7:34 pm

I just installed a fresh install of Raspbian and I clicked the wifi icon but it said that there are no wireless devices. I'm using a wifi adapter as a temporary solution. I typed ifconfig and the ifconfig -a but only eth0 and lo came up.

Does "fresh install" mean a recently downloaded image? Have you done an update?

Code: Select all

sudo apt-get update
sudo apt-get upgrade
Go here for my RPi writeup. Basic config, Serial Port add-on etc:

I have this same issue, downloaded and installed raspbian from the image named 2016-02-26-raspbian-jessie.img Install went just fine, I set the wifi region using raspi-config, but clicking the networking icon shows "No wireless interfaces found" Dmesg doesn't report any wlan interfaces, no messages about brcm firmware are printed, though the firmware seems to be present in /lib/firmware/brcm. Here's the output from lsmod:

Run rpi-update to get the latest firmware version 4.1.19. It will disable the WiFi power management automatically.

I ran rpi-update last night, no changes. I also manually disabled wifi power management, still not even appearing.

I'm not entirely sure what the symptoms of the power management bug are. The symptoms I'm experiencing look like the device isn't even present, no kernel modules are loaded, and none of the iw/ifconfig style commands even show it.

To be clear, my issue isn't that I can't get the wifi to join a network, or that it drops connections periodically. Raspbian isn't even reporting that the physical device exists.

I also have a similar problem in my new Raspberry Pi 3 which I bought 3 days ago. Bluetooth is working using Bluetooth blueman manager. I can't view wifi networks in range. I have Wicd and network manger. There are 2 computers connected to each other on top, when I click it, it shows "No Wireless Interfaces Found". It only works through Bluetooth teacher from android and Ethernet Cable. My raspbian version is Raspbian Jessie. I have updated and upgraded it also. Still I can't find a solution and also no wifi icon is there in top right-corner and no wifi config icon on Desktop.there is only WasteBin icon on desktop and nothing else.


Please tell Me. Your help will be appreciated. :?: :?:

Regards,
DcRPi3

Get NOOBS 1.9 or Raspbian Jessie 2016-03-18 and either of those should fix your WiFi problems (assuming the hardware is working).

I also had the problem "no wifi at all" i.e. 'ifconfig -a' didn't even show 'wlan0'.

What helped me was to simply install 'firmware-brcm80211'.

Works great now :-)

Try this

sudo touch /etc/network/if-up.d/wlan0
sudo chmod +x /etc/network/if-up.d/wlan0
sudo echo -e '#!/bin/bash\niwconfig wlan0 power off' > /etc/network/if-up.d/wlan0

FWIW, I had also "lost" the Wi-Fi adapter in my Pi 3. Bluetooth was still working... kernel modules and firmware were fine... I banged my head on the wall for a couple of hours!

The problem was with the dtoverlay=sdhost,overclock_50=100 line I had added to my config.txt to (supposedly) overclock the microSD card slot. After removing it, wlan0 is there again. If I add it back, no more wlan0.

So my suggestion to anyone with a missing Wi-Fi adapter on a Pi 3 : Double check and disable any config.txt tweaks! :-)

Hello Everyone

As I am also new to raspberry pi, and I have purchased a raspberry pi 3B.

I want to connect my board to WiFi router in STA mode, but it is always showing "No Wireless Interfaces Found". I have also already done as per mentioned in the thread above and have tried dozens of ways mentioned on web but they are of no use till yet.

If someone finds a solution to this problem. Please help.

It is easier to use an external USB adapter, since the antenna on the board is not that great.

Use "lshw | more" to list all hardware. The | more allows you to use the space bar to go to the next page. hwinfo will also show it.

If the Wifi driver was not blocked from running. Iwconfig should show it.

Keep this as a quick reference. http://www.binarytides.com/linux-comman ... ware-info/

I'm seeing this issue as well. No bluetooth, no wifi on my raspberry pi 3. I tried installing rasbian latest build available on downloads from May, I've tried using NOOBS, and I did the rpi-upgrade as well as using apt-get update / upgrade.

I do see this in systemctl list-units
hciuart.service loaded failed failed Configure Bluetooth Modems

I've got nothing plugged into this thing right now, and it's a vanilla install. I have just an ethernet cable plugged in and a monitor.

What are you using for a power supply? If you are using a phone charger, or anything with less than a 2A rating, get a better PSU. The recommended power supply unit for the Pi3 is 5.1V, 2.5A.

Hi, just in case it might help.
I was following this tutorial https://www.sunfounder.com/wiki/index.p ... spberry_Pi

Basically, after editing the sudo nano /boot/config.txt file and setting
device_tree=on

broke my wireless on the next reboot. Deleting that line solved the issue.

Im having the same issue, however I have a stock install of retropie 3.8.1. I did perform the updates through the system but I have not manually changed anything at command line. I also tried NOOBS raspbarian, and it is doing the same thing there so I believe it transcends operating systems.

Hi, I just got my raspberry pi 3 from my FYP supervisor. I have not much knowledge of it yet. Just downloaded NOOBS v1.9 on my com and transferred to the SD card. However my raspberry pi can't connect to the wifi . During recovery mode I can't click the wifi network and when it start, there is no wireless interfaces found.
PS: I already did sudo apt-get update/upgrade

I had this same issue before. I suggest you instal a package called
wpa-gui. It should be able to help scan for networks and helped in my situation

Just to note (and bump this thread) that the 'can't find interface' issue remains for me with the latest Raspbian (September 2016 / Pixel). Circumstances:
  • Clean install of Raspbian (or NOOBS) to a Pi3.
  • Wifi interface found and functions correctly.
  • [time passes. Could be a month, could be a few hours.]
  • Wifi icon in menu bar reverts to broken network image; mouseover text reads "No wireless interface found".
  • OS updates don't appear to solve the problem, but:
  • Wipe and clean install of card (usually) does. Repeat from first step.
We've seen this behaviour on I think all the Pi3s we have to hand (about 5?), none of which has had any SD card overclocks. In all cases we've had to revert to USB wifi dongles.

I think I've read all the threads on this, but the majority of messages are about failure to find or join a network. This is a failure to find the interface, and while it doesn't seem to be widespread generally, it's completely endemic for us.

What is the output of dmesg after the wifi device disappears?
