Raspberry Pi ZERO W no wifi interface found...

[dverleysen]

Hi,


I bought this week a Raspberry Pi ZERO W and it's a struggle to config that thing! Tried to setup as a headless device but I had to much problems so I bought some adapters to connect screen and keyboard.
But I cannot find any wifi icon or connection, when I run raspi-config I get the message that there's no wireless interface found... WHAT?

Hereby some screenshots and a shot of the back of the device

Are you sure it's a ZeroW a cat /sys/firmware/devicetree/base/model;echo command will tell you.

Code: Select all

pi@mercury:~ $ cat /sys/firmware/devicetree/base/model;echo
Raspberry Pi Zero W Rev 1.1
pi@mercury:~ $

@dougielawson that is what I see on the back --> https://photos.app.goo.gl/3UKAkJiHcweo8bLd7

And when I run "cat /sys/firmware/devicetree/base/model;echo"

I get = Raspberry Pi model B Rev 2 ????????????????

Then your SDCard is full of junk.

Get latest 2018-04-18 Raspbian and Etcher. Use Etcher to write Raspbian to your SDCard.
https://downloads.raspberrypi.org/raspbian_latest
https://etcher.io

@DougieLawson it's this version created with Etcher.

Similar issue like this? viewtopic.php?t=178362


I just downloaded the image again, and use etcher to flash the card. = Same issue

Then you need to return your Pi0W for an exchange. It's defective (SoC was not properly programmed).

I am having a similar problem with my Pi Zero W which I have been trying, frustratingly for 3 months, to get wifi to work headlessly.

I was not getting it to connect headlessly to my network so I spent extra money to get HDMI cables etc to see what was going on. I found that no wifi interface found. So I sent it back and got a replacement.

So this weekend I have installed 2018-04-18-raspbian-stretch.img on the new pi. Plugged it all in and seen it come up on the monitor with the wifi interface working. However, I do not have a keyboard to plug into the pi and enter the wifi password(and I don't want to spend any more money on this project). So I removed the card, added a wpa_supplicant.conf file with the necessary information. inserted back into the pi and restarted.

It booted successfully however the wifi now says no wifi interface found. I tried this twice with a newly imaged os and the same thing happens. So it appears the wpa_supplicant.conf file is causing some major issue with the wifi interface.

Surely, this can't be just a few of us this is affecting? I am about to send all of the pi stuff back to get a refund. I have wasted too much time on this project already. Unless someone has a simple fix.

Please help

What is in your wpa_supplicant file?
What is the network security type?
Does the network hide its SSID?
