Problem with Pi Zero W and wireless/bluetooth

That’s mighty strange, could you whack a photo of them up on here?

The very occasional one having hardware issues is likely, but the chances of you coming across two are slim.

This is with a brand new Jessie/Jessie Lite image from https://www.raspberrypi.org/downloads ?

And no rpi-update (curse its very existence!) tomfoolery?

If you run sudo dmesg | grep 80211 on either, do you see anything?

I’m at work at the moment. But yes. Done all that. I’ve got a bad 2. Typical. Luck of the draw. Had to happen to someone. And they Are both v1.1 W’s

I have reloaded them both with each of the last 3 releases.
Same issues. Boot up fine. Just no wifi. Ssh’d in no problem. Just no wifi.

I am confused, how are you getting in via ssh? perhaps if you have an ethernet adapter it is somehow messing things up… or have you configured them for otg?

Hi there,

Hate to add to your woes, but same thing. Here’s what I’ve done:

  1. Downloaded latest Raspbian Jessie (after Lite gave same bad result as this),
  2. Done apt-get update/upgrade
  3. Done rpi-update
  4. Configured with a static address on wlan0 (other methods produced IPV6 address?)
  5. Configured wpa_supplicant.conf

Currently:

  1. dmesg with 80211 or Bluetooth shows nothing
  2. GUI shows ‘no interfaces found’
  3. ifconfig shows the static address I configured
  4. ping etc. shows no network

So I’m now stuck. One thing I didn’t try from elsewhere is moving the ssid and password into interfaces file.

Shall I return it? Best regards Hugh

Can you run vcgencmd otp_dump and post the output?

Cheers!

Looks like the revision ID is correct, I suspect there might be a board-level (hardware) fault with your Pi at play here.

You should never use rpi-update by the way, it’s not an update tool, but instead installs pre-release kernel, modules and firmware on your Pi.

It’s possible, also, that there’s something up with your wpa_supplicant.con but I’m not quite sure how to test for that. What happens if you do:

sudo wpa_supplicant -iwlan0 -c/etc/wpa_supplicant/wpa_supplicant.conf

That gives me:
Successfully initialized wpa_supplicant
and then it blocks until I control-C

Thanks for the tip about rpi-update, that should be a little more prominent.

Aha (for others too), just found:
sudo iwlist wlan0 scan | grep <part of my ssid>

This turns up my complete ssid, so you are right there’s probably something else wrong with wpa_supplicant.conf or the config somewhere else.

So, thanks, I’ll carry on for a bit, but it looks as though this is not hardware.

Thar’s interesting. I wonder if it’s a rogue character or something making its way into wpa_supplicant.conf. Did you create the wpa_suppliant.conf on a Windows PC and drop it into /boot?

Ok, nearly there, I removed the proto and pairwise entries in my wpa_supplicant.conf to make the whole thing more liberal and now:

brings the network up, then blocks. I can ping, be ping-ed etc. So, a few things to clear up, such as network doesn’t seem to come up automatically on boot, but, if necessary I can work around that. Next stop ssh, but that should be simple?! Thanks again for your help.

With the right wpa_supplicant.conf in place, network should come up automagically on boot. You could try sudo ifdown wlan0 and then sudo ifup wlan0 to give it a kick.

All good now, thanks, ssh and (because I’m lazy) sshfs too. Last problem was interfaces file, now reverted to default and collect IP address from dhcp on the router. Not quite what I want but it’ll do for the moment.
