I can’t seem to get anywhere with setting up wifi on my BBBW. I installed latest image (Debian 8.7 2017-03-19 4GB SD IoT )

Whenever i try to any wifi related command with connmanctl i get: Error disabling wifi tethering: Method “SetProperty” with signature “sv” on interface “net.connman.Technology” doesn’t exist

Here is what i get from ifconfig:

`

debian@beaglebone:~$ sudo ifconfig -a

Just grab:

Thanks for your reply.

I tried the image you suggested and i’m getting the same result. No wlan0 in ifconfig and all connmanctl commands fail.

Please run: "version.sh" (under /opt/scripts/tools ) and share the output:

There's the problem ^ eeprom was corrupted when wrote..

"if this is a bbbw"

GND TP1 and run:

sudo dd if=/opt/scripts/device/bone/bbbw-eeprom.dump
of=/sys/devices/platform/ocp/44e0b000.i2c/i2c-0/0-0050/eeprom

then run:

sudo ./version.sh | grep eeprom and it "should" show:

A335BNLTBWA50000BBWG0000

then you can safely reboot :wink:

thanks for addressing this. it seems to be the same behavior I’m encountering with the 4.9.25-ti-r32 kernel from May 5 on the BBBW.

FWIW this is my version.sh output:

FWIW this is my version.sh output:

eeprom:[A335BNLTBWA51646BBWG1217]

thats the correct eeprom for the bbbw

No 4.9.x-ti is still just really really buggy on wl1835..
