Ethernet not working on Android (my dicoverys)
#1
You probably read about this problem several times. But i wanted to share with you what i could find out.

I got the 2GB Model of the Pine and I am using the Rooted Android 5.1.1 Image Release 20160428 [BETA]
I DON'T have the WiFi/Bluetooth Module.


After several tries of failure i decided to make a new clean installation and proceeded as follows:

- Install the Image
- Boot up the Pine with only the Power and HDMI connected
- Unplug the power after 10 minutes without doing anything else
- Wait another 10 minutes and hook up the Ethernet Cable and the Mouse and Keyboard
- The displayed time at the top right switch from 4 o'clock to the accurate time at that moment like there was a connection to a timeserver
- No Ethernet connection what so ever and the RJ45 Jack was blinking continiously
- The Pine is registered in the DHCP/DNS Services on the router. I knew clearly which IP it was since it was the only Android via LAN not WiFi. Also i checked it cmd ping while it was plugged in and out so i am 100% sure that it was the correct device.
- During the ping i noticed that i had a LOT of packet drops, since it was directly connected to the router where the pinging computer was also connected with a distance of 4 Meter cable. So there shouldnt have been even a single drop and i had about 25%-50%
- This lead me to believe that the Ethernet module might be busy trying to broadcast or something. But Wireshark gave me nothing. The only things i could see where my Pings and the registration when i plugged in the Ethernet Cable


And now comes another interesting observation

- My brother has the exact same Pine with the exact same configuration and the exact same SD card... BUT... he has the WiFi/Bluetooth module. And on his Pine64 the Ethernet connection worked after some time and pluggin it in and out.
- Same thing happened to another user on the Pine64 Chat

My conclusion: Either they downloaded some updates for Android before (unknowlingly) and this got it to work somehow  OR the Pine64 tries to find the not exisiting Wifimodule, even if it's deactivated. Just askin if it's there to go on with the program and use the Ethernet connection and thus getting stuck on that request.

Tomorrow my brother will bring his WiFi module and i am going to check it out and give you my results. I hope to help some people out with a bit deeper insight.

Kind regards
