I recently upgraded by VOX2 Sentinel from SDK 1.0.X to 1.3.3. Prior to this upgrade, I had no issue configuring and connecting to its wifi. Now, after the upgrade, voxl-wifi (run from adb shell) displays "Error: wlan0: error fetching interface information: Device not found." Indeed, ifconfig does not show wlan0. Additionally, the wifi dongle used to flash or showed blue after powering up, but now it does not show anything. Power cycling does not help. Also, nothing about the wiring to the wifi dongle has changed prior to upgrade. How do I fix this?

@ craigphoenix I had this issue as well. One of the devs said the connectors can come loose sometimes. Try pushing both ends tight through the heatshrink

@craigphoenix , I think the SDK install is failing somewhere in the middle (but goes unnoticed) and the ESC update and wifi issue is a result of that. We have not see this behavior before, so it is best to send the board back for inspection.

Thanks!

Alex
