no wireless interfaces found raspberry pi 3 как исправить
Хорошо, я не смог найти решение этой проблемы где-либо еще в Интернете, поэтому, пожалуйста, потерпите меня:
У меня есть новый Raspberry Pi Model 2B, который поставляется с ключом Wi-Fi (Ralink RT5370), и когда я запустил его с предварительно установленным Raspbian, Wi-Fi работал правильно. Я также купил экран mini HDMI для pi, который не работал бы без установки драйвера с DVD-диска, поставляемого с экраном. После установки драйвера экран работает хорошо, но теперь мой wifi перестал работать. Индикатор на ключе больше не включается, и я не могу найти беспроводные сети.
И когда я запускаю, sudo ifdown wlan0 && sudo ifup wlan0 чтобы увидеть, достижима ли сеть, я получаю следующий вывод:
Я пытался редактировать оба /etc/network/interfaces и в /etc/wpa_supplicant/wpa_supplicant.conf соответствии с различными примерами онлайн безрезультатно. Вот мои текущие версии:
В качестве примечания, я трижды проверил, что информация о моей сети верна и что сеть Wi-Fi обнаруживается с других компьютеров, поэтому я сомневаюсь, что проблема на этом конце. Я нахожусь в точке, где я действительно не знаю, где и в чем может быть моя проблема. Я пытался скачать менеджеры Wi-Fi, это не сработало. Я неоднократно перезагружал, обновлял и обновлял свои версии программного обеспечения, но это не помогло. Я попытался изменить и / или удалить строки из вышеуказанных файлов, которые не сработали. Я постоянно не могу сканировать беспроводные сети (Примечание: Ethernet работает нормально), несмотря на успешное подключение к сетям перед установкой этого драйвера экрана! Если кто-нибудь знает, что может быть моей проблемой и как ее исправить, я был бы очень признателен. Благодарность!
No wireless interfaces found raspberry pi 3 как исправить
Hello everyone!
I’m having a problem with my raspberry pi 3 model B.
When hitting on network settings button on home screen I’m getting «no wireless interfaces found» error.
When entering network settings with the right click I’m getting Config Error:
Error saving /etc/dhcpcd.confi
The dhcpcd config file is not writable.
I have changed wpa_supplicant.conf and network/interfaces as provided on raspberry website.
Non of this worked. I neither have Ethernet cable nor PC next to me now to reinstall the OS.
Please help me if possible. I’ve been surfing through the old posts but nothing really solved my problem.
Cheers!

I have also hit the same problem and have yet to find a solution: viewtopic.php?f=28&t=189889&p=1194238#p1194238
Good luck with your problem, if I find something I’ll let you know, and if you find something out, I’d appreciate some information, too.
Most of the replies I’ve received have been from people who have not read or understood the problem («Your wifi is turned off!» «Are you sure you have a wireless network?») and yours is the first one I’ve seen matching my problem (the interface on the Pi itself seems to be down).
Re: No wireless interfaces found
Re: No wireless interfaces found
I ran across a similar problem today. In my case, the reason was that I was logged in as a new user, which I added after installing the pi os. By default, the ‘pi’ user belongs to most groups that can control interfaces etc. but my new user was not in those groups.
So I edited the /etc/group file to add my new user to the same groups as the pi user.
(or just follow the guide here)
These group ‘pi’ belonged to were:
pi adm dialout cdrom sudo audio video plugdev games users input netdev gpio i2c spi
As others have pointed out this is most likely a permissions issue.. If the above is not the issue then check which user/group can read/write to /etc/dhcpcd.config by executing the following command in a termal:
The returned output will be in the following format:
rwxr-xr-x 2 owner group 4096 Aug 12 19:12 dhcpcd.config

Re: No wireless interfaces found
So I have just powered up my PI3 and according to the network ICON on the task bar «no wireless interfaces found», the ICON is just showing two vertical errors.
Yet, when I tap in ifconfig under wlan0 I have a valid IP address and can connect via the wireless to the internet.
Worrying because I was helping a friend setup their PI3 using the following method :
1) use etcher to burn latest jessie to sd card
2) on the root create a file called ssh
3) on the root create a wpa_supplicant.conf file with wifi details
the task bar displayed the same status, i.e. no wireless networks found.
Because the above steps with the same wpa_supplicant file had worked the day before (on same network) we concluded that there is a problem with the wifi on the PI3.
this may not have been the case.
has anyone experienced the same problem and sorted out what is happening?
Re: No wireless interfaces found
I have the very same problem on my Pi Zero W. Jessie shows no network interfaces, yet wireless Internet works just fine and I SSH into it with no problems.
What file(s) does Jessie look at to see if there are any network interfaces? Perhaps Jessie is not running with the correct perms and is unable to read that file(s)?
Re: No wireless interfaces found
I solved the issue by deleting /etc/network/interfaces.
On a fresh install the file does not exist. I created it a configured the eth0 interface because I was taking the py on the go, with no wi-fi.
I figured that was the ONLY change I had done in networking, so it oughta be the reason.
Deleted it, rebooted, and there it is. wifi is working again.
No wireless interfaces found raspberry pi 3 как исправить
When I boot to desktop I see error that «No wireless interfaces found» on a RPI 3 B+, and of course there’s no network connection.
The same SD card works flawlessly when inserted to older RPI 3 B (without plus). What’s wrong? How to fix this problem?
I tried rpi-update, upgrade, dist-upgrade. No luck. any ideas how to fix this problem?
Re: RPI 3 B+ No wireless interfaces found
then select localisation options
then change wifi country.
you may also need to unblock the wifi using this command
Re: RPI 3 B+ No wireless interfaces found
Thank you for quick answer. I did this already.
Am I missing something? The same SD card when I put to old Raspberry Pi 3 B v1.2 (not B+) works perfectly fine and wifi is started.
I think it is worth noting that the system is via NOOBs and it was upgraded from older version to the B+.

Re: RPI 3 B+ No wireless interfaces found
The Pi 3B+ has been running for awhile now, and has been through several update/upgrade cycles, with the only problem being the shutdown kernel panic due to the recent (and buggy) 20180910 firmware release, which has since been fixed, and did not cause connection issues with my wireless network. The symptom of the bug was that shutdown would fail and end in a kernel panic if Bluetooth was turned off, but there were no problems booting and connecting to WiFi.
What are you using for a power supply?
Re: RPI 3 B+ No wireless interfaces found
Re: RPI 3 B+ No wireless interfaces found
I updated from Jessie to Stretch and I’m bricked out from the Internet too. This is ridiculous.
I can’t even get into the Networking GUI.

It was never recommend to upgrade from Jessie to Stretch because a working system was never guaranteed after the upgrade, people found there was mixed success.
The recommend way to upgrade to Stretch has always been to flash a new image to an SD card.
Re: RPI 3 B+ No wireless interfaces found
I understand that you had trouble with wifi, though one further question about your issues.
Why did you not have network? Wired ethernet should still have worked without problem, what else was wrong?
Re: RPI 3 B+ No wireless interfaces found
I *just* ran to this very same problem myself.
I was fiddling around with connman, which caused some havoc. After 20 mins of crazily whaking my keyboard, I ended up in a situation that wlan0 could not connect to an AP. whoops.
I decided to enter X, only to see that dreaded «No wireless interfaces found» message, and got those same wpa_supplicant error messages while running sudo raspi-config from a terminal.
To fix this, I did the following:
1. I checked my /etc/wpa_supplicant/wpa_supplicant.conf file, and removed all but one wifi network (examples of wpa_supplicant.conf can be found above in this thread).
3. enable service: «sudo systemctl enable wpa_supplicant.service»
5. boom. instant profit.
PS. I also upgraded from Jessie to Stretch without creating a new SD card image. Oh, and connman does not work on Raspbian without first disabling some other services managing the wifi.
No wireless interfaces found Pi 3
I have a Raspberry Pi 3 Model B and was using the inbuilt Wifi interface with no problems. I was using it as a web server which I’d SSH into. However, after being unable to SSH into it, I’ve seen that it’s now showing me the message «No wireless interfaces found» in the Raspbian UI taskbar.
What could cause this to stop working so suddenly without (to my knowledge) any messing around with config settings? How do I fix this? The Pi has just been sitting on my desk so I can’t imagine it’s physical damage.
The output of ifconfig :
Although wlan0 is displayed in this output, the Raspbian UI is not reflecting this.
I should also note, because this is often an issue, that my power supply should be sufficient as I’m using the official 2.5A PSU.

Have you tried setting it up before you even boot it up? I was trying to set up a pi zero w but didn’t have the right adapters. So I found a way to set it up in Windows. This is the easiest way I found to do it and have done several times now.
Instructions from the site.
This is where we enter our WiFi details. Enter the following text into the file, replacing the placeholder text with your own details.
SSID is the name of your WiFi network, and psk is your WiFi password.
By default, the current version of Raspbian has SSH disabled. We’re going to enable it here.
Create an empty file in the boot directory called ssh
Your Pi is now ready for startup. Eject the SD card from your computer and insert it into your Pi. Power up your Pi (we recommend an official power supply) and wait a few moments for the initial boot to complete. On your computer, open up PuTTY.
We know that the default host name (the name of the machine) for a fresh Raspbian install is raspberrypi, so in the Host Name (or IP address) field enter raspberrypi. This searches for machines on that name on the local network. Once a connection is established, you’ll be prompted by PuTTY to accept the connection to the new machine. You should see a black terminal prompting for a login. Enter the default username: pi and the default password: raspberry
If you get an error saying the host does not exist, try the troubleshooting steps.

And yes I have tried, apt-get update/upgrade cycle, reboot.
Re: RPI 3 No wireless interfaces found
Re: RPI 3 No wireless interfaces found
I too have had this affect my rpi3. It was working fine the first day I took it out of the box. Then I shut it down, and a few days later when I powered it back up, I have the «no wireless interfaces found». I have tried every single tip and trick I can find online.
Does anyone have a fix for this?
Re: RPI 3 No wireless interfaces found
I noticed it was down then plugged in the hardwire and then did the update/upgrade reboot.
I should also note I am using a 5V/2.5A power adapter. A lot of post are saying a power issue so I wanted to check that once off.
Re: RPI 3 No wireless interfaces found
I seem to have fixed my issue. I decided to blow away my /etc/network/interface file that I customized to static ip. I did not do this today buy a long time ago. No clue why it happened today. Maybe a reboot? I cleaned up the file to what I thought was pretty close to the default settings. That fixed it. Then I went back into it and updated it again with my static IP updates.
That fixed it for me. If anyone else is setting a static IP I’d like to know if this fixed the issue for you.

If you are using Jessie, read the top lines of the interfaces file before trying to give your RPi a static IP address.
If you have ignored that, any trouble you get is of your own making.
