RasPi 3b+ no wifi

Post by thisisstupid » Mon Apr 09, 2018 12:26 pm

Order ID: 226591
Product Name: Raspberry Pi 3 Model B+ & 16GB MicroSD Bundle - Includes Raspberry Pi: Raspberry Pi 3 B+ **MMP-1153** - Micro SD Card: 16GB Sandisk w/ Official Adaptor (Class 10) **SAM-0002**
Model: TRPLUSKIT-A

I bought 4 on one the wifi doesn't work.
shutdown restored original image, no wifi
shutdown tried different power supply, no wifi
shutdown tried different sd card, that boots and connects to wifi on one of the other pi's, no wifi
shutdown tried different usb lead, no wifi
shutdown plugged in usb wifi adaptor, connected directly to wifi.

I'm pretty sure the wifi chip on one pi is dead.

thankyou for forcing me to sign up to a forum

I'm really sorry about that!

Thank you for the detailed troubleshooting you have performed, this greatly speeds up the replacement process.

It does indeed sound like the Pi is faulty.

I will have a return for replacement arranged for you now.

I've received an email from Hermes asking me to print the attached label for return, but there is no attached label :?

How strange? An email has been sent to from our sales team with the shipping label attached. Hopefully that one will come through!

Hi,

No way! I'm really sorry for that, I can confirm it's definitely a different unit, we've actually got your original one here as we use the "broken WiFi" Pi's for various testing bits and pieces.

But, the replacement would not have been tested as the assumption is that stuff should work straight out of the factory. . . :roll:

I have just grabbed another unit off the shelf and tested the WiFi is working, so I'll get that shipped out today, and have another return raised for the replacement.

Really sorry for this. It's most unusual.

OK so the new pi arrived, micro sd in boot no wifi, reset memory card with fresh os and copied my wpa_supplicant.conf & ssh files to boot as normal powered up the pi and no wifi.
I know you tested it so tried using the full raspian image instead of the lite version copied wpa_supplicant.conf & ssh files to boot started the pi and it connected directly to wifi.
I removed the sd card and wrote the lite image to it again and theres no wifi, connected it via ethernet lead and did apt-get update, upgrade etc rebooted no wifi then tried rpi-update rebooted no wifi
found this page: https://www.raspberrypi.org/forums/view ... p?t=138137
I followed the suggestions, The files brcmfmac43430-sdio.txt and brcmfmac43430-sdio.bin are present and powersave is set to off rebooted still no wifi. used rpi-config to manually set the wifi settings and rebooted no success.
I'm at a complete loss now the really confusing thing is 3 of the original 3b's that arrived are all running the same version of raspian stretch lite I've even gone back to the raspberry pi website and re-downloaded the image incase it somehow became corrupt but thats made no difference.

I'm off to the shop in a minute so will pop the other one back in the post

This is very strange indeed! The fact the WiFi works with the full version of Rasbian would indicate that its a software issue in Rasbian Lite.

Have you taken the SD card out of a Pi3B+ that has working WiFi and tried it?
