Driver error -wifi

Technical Support
#1

Hello community :D

I’ve added a wifi driver to my source code, and it was successful… Now I can scan and connect to wifi.

The problem is that I can not do tethering ( ethernet to wifi AP), noting that Ap works fine without ethernet

Attached in my logcat : dogbin - grunamynaf

The problem should be that there is something wrong with your added wifi driver

this wifi module seems does not support Android system according to the webpage

Well, I managed to make it work. I can scan and connect to wifi. the only problem I have that i can not do the tethering (from ethernet to wifi). it seems that there is some missing configuration. (one of the usb vendors, official vendor, says in his website that this usb support Android)
