RPi model 3B+ wifi connection issues

Post by otucek » Thu Nov 29, 2018 3:15 pm

Hi,

we ordered (order ID #243615) Raspberry Pi 3 Model B+ Budget Kit & Cables (UK/EU 16GB). Unfortunately we can not establish connection to RPi through wifi. In a listing on the screen we got the message
"IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready".

We've already tried:
- enable wifi by 'raspi-config' => no success
- format the SD card and reinstall rasbian as per these instructions - http://s.modmypi.com/noobs => no success
- format the SD card and install ubuntu-mate-16.04.2-desktop-armhf-raspberry-pi => no boot (it will appear on screen in the top right corner yellow lightning bolt), i.e. no success
"yellow rainbow" screen appears in the top right corner)
- another SD card + 2018-10-09-raspbian-stretch-lite => no success
- we connected RPi by ethernet and updated system => no success

Any suggestions how to fix it? Or is it possible the replacement of RPi (by "weaker" version of RPi 3B)?

Many thanks
O.T.

Sounds like the WiFi may be faulty, I will have sales contact you to arrange a return for a replacement.

Do you want the replacement to be a RPi3 B (instead of the RPi 3B+)? Please confirm.

We've tested both the Pi and SD card but have been unable to identify any problems.

The pi connects happily to our WiFi and is able to browse the internet without any issues.

Could you explain in some detail what you are trying to do?

When you say

Are you using IPv6 and if so has it been enabled by editing the modules file:

Code: Select all

sudo nano /etc/modules
and adding a line

Code: Select all

ipv6

That's weird.

We tried that. Also we had actually the problem with IPv4. RPi didn't find any of these protocols. Wi-fi was still down.

Do you have other devices connected to the WiFi?

Did you set the correct WiFi country when promoted on first boot?

How would you like to proceed? I'm happy to send this unit back to you, or I can send a replacement RPi 3B as originally asked? Up to you :)

Yes, me (Lenovo T420) and colleague of mine (MacBook Air, Early 2015) via notebooks.

Yes.

We would like to prefer the model RPi 3B (not +). So if this isn't problem, please send us RPi 3B. We appreciate it.

Thanks a lot for your helping and willingness.
