Wifi Doesn't Work


#1

Hi Guys,

It’s awesome to be part of this community, and own this cool board.

I haven’t been able to turn on Wifi in Android. It doesn’t scan, I also noticed that the MAC address and such are not listed in options! Do I have a defective board?

Cheers!

I received 2 boards yesterday, wifi on both appears to be working just fine. Can’t comment on MAC addresses, since I didn’t check that. I didn’t have to do anything special to make it work, just turned everything on, system settings --> wifi --> hit the on button, then wait a few seconds for my AP to appear.

What do you mean by “won’t turn on”? The on button doesn’t turn green when you hit it? Failure to detect anything doesn’t necessarily imply that there is a fault. The antennas on these are not especially impressive. I notice fewer scan results than other wifi devices I own.

Hi thanks for your reply! I appreciate your help.

The device powers on perfectly fine. But when I try to enable Wifi (in Android settings) it switches on but doesn’t actually detect any networks, then turns “off” after about 10 seconds. I’ve tried to done a few factory resets, and wiped the cache partition but it hasn’t remedied the issue.

Hi araychau

What release are you using? I just validated successfully 15.06 on my board - maybe you could give it a go:

The Android upgrade instructions are located here

The 15.06 release here:
https://builds.96boards.org/releases/dragonboard410c/qualcomm/android/15.06

Note: corresponds to:

Incidentally please notice that the kernel is failing to read the MAC address from the device and ends up generating one by software.

if you are still having issues with 15.06, please could you share your dmesg?

Hi Idts,

Thanks for the detailed info.

I’ll be honest I’m a noob at this stuff. So I appreciate the help!

I am using Build Number:
msm8916_64-userdebug 5.1.1 LMY47V eng.c_bpatth.20150520.211305 test-keys

Kernel Version:

I tried to take a bug report through the developer options, but it doesn’t seem to generate anything. How do i get a dmesg?
