Ethernet stops working on many Orange Pi 3b units. #139

Please see: https://old.reddit.com/r/OrangePI/comments/1aojmn3/orange_pi_3b_ethernet_doesnt_work/ for the conversation so far.

Something is happening to dozens of people's 3b units, it seems to be related to using the official images.

If it is the firmware being updated to a faulty release, it would make sense that other OSes tried after would continue having this issue, which is the case for many.

Orange pi update vccio5 from 3.3v to 1.8v in device tree for 3b v2.0 , vccio5 is Ethernet power supply. Why voltage is changed in next hardware version, 1.8v better than 3.3v?

i have the same problem :(

it's in a functional state running the command as above. run as root, don't restart or you need to do it again. has worked for everyone else that has this issue.
