OPi2, where is my WiFi??

quwy

Hi all!

It's time to real use my OPi2 but I surprised by total onboard WiFi adaptor invisibility. Module exists on the PCB, but I can'to to see it from the OS.

This is not depend from the linux distribution. Official Android also does not see any WiFi hardware.

I got a defective board or need to someway enable WiFi?

igorpec

Those recent boards have different / new wifi chipset which is (probably) not supported by any of images from download section ... but it works under Armbian and Openelec.

Thank you for reply, but unfortunately all these copy-paste from latest armbian OS

What you get from:

1. lsmod

Copy code

If you don't see 8189es load it. Enable wlan0 and scan for example:

1. ifconfig wlan0 up
   
2. iw wlan0 scan

Copy code

It should scan for AP in range.
You can't see it with lsusb since it's not connected via USB.

Module is present:

1. root@orangepi2:~# lsmod
   
2. Module                  Size  Used by
   
3. gspca_zc3xx            34888  0

5. 8189es               1076034  0

But device does not exists:

1. root@orangepi2:~# ifconfig wlan0 up
   
2. wlan0: ERROR while getting interface flags: No such device

Copy code

igorpec

ok. Try this, removed this module from /etc/module and replace with:

8189fs

reboot ... and repeat previous commands again.

quwy

Same situation, module 8189fs loaded, but device wlan0 (wlan1, wlan...) does not exists.

WiFi adaptor on the PCB is marked as CREATEK CK-W-R189-SM.

Check power supply.

Check power supply.

Checked. I tried three different power adaptors including laboratory 5V/5A supply. Also external USB-WiFi dongle works fine.

Can provide datasheet of wifi module CK-W-R189? Maybe fail connection/ pcb path. Might be able to trace if datasheet available...
