No WiFi any more

Mon Feb 29, 2016 1:05 am

Hey all,

I've just received my VoCore recently and started playing around a bit. With the original firmware (Barrier Breaker) everything seemed to work fine. I could access the AP, I even got an 802.11s mesh WiFi working. Since I wanted to add some custom stuff to the firmware I built a new image off current OpenWRT trunk. I installed it using LuCI, everything seemed to work. It booted up fine. But the WiFi never came online.
I suspected it was my firmware, so I tried all of Vonger's firmware images I could find (I tried vocore.bin, vocore16.bin, vocore.v1.0.bin and vocore.dock2.bin), all of them are Chaos Calmer. Still, the issue persists. From the UART console everything looks fine, as if the WiFi would work, but it never shows up on any other devices.

The only thing different is
Code: Select all
iw dev wlan0 scan
not producing any output at all and in many cases actually resulting in a kernel oops:
Code: Select all
root@OpenWrt:/# iw dev wlan0 scan

Any idea what's happening? Can I find the original BB firmware anywhere to test if it's a firmware or hardware issue?

Best,

Looks like the factory setting section is not correct, please check partition "factory"

Somehow my last post was never published, so here it is again:

This is my factory partition:

I guess the latest openwrt wifi driver is broken, this happens before :)
Better to use stable version but not latest version.

As I said, I've already tried all your images that I could find. None of them worked. Do you have the original image that was on the vocore somewhere (the Barrier Breaker image)? Is my recovery partition alright?

The factory setting is correct.
Do you try this one? http://vonger.cn/upload/firmware/vocore.dock2.bin

That's weird, never meet such issue before.

Is it possible the wifi hardware somehow died?

Is there a solution to this problem?
I have exactly the same symptoms after installing Chaos Calmer (Vocore) and resetting to defaults. No more Wifi (visible on a scan networks. Haven't tried going through the serial yet)

Next
Return to VoCore & VoCore+Dock
