Ethernet adapter usb 2.0 by usb OTG
Confirm that "plugable usb to ethrnet 2.0" is working very well on kitkat tested on .757 update. You must set by terminal emulator ifconfig and gateway, here an example:
ifconfig eth0 10.10.0.111 netmask 255.255.255.0
route add default gw 10.10.0.254 dev eth0
It's incredible! Now i can browse by ethernet!
Next i will post the picture, problem uploading..
