One of my orange pi zeros eth seems to be only negotiationg down to 10Mb/s full duplex.  Not sure why.

 

Below are examples of a stock nightly build. it only happens on one of the pis.

Manually 

ethtool -s eth0 speed 100 duplex full sometimes work, other times the interface starts moving up and down continually

 

but even if it works its for a short period of time

especially if i put some load on it

Any ideas?

 

 

 

 

Trying different cables?

Does this Orange Pi Zero only get  10MBit where another Orange Pi Zero does get 100MBit - or do you use with this Zero another cable?

I have already tried different cables.  It did not seem to help any.

Also tried those cables on other pis/other devices and they all seem to work fine.

Did you try on the old kernel as well?

then I would suggest to use all components from a working Zero/one:
- Network-Cable

- uSD-Card with OS
and
- Power-Supply

 

on the false-working Zero/one - then you could also eliminate the problem with the kernel/OS which Igor mentioned

 

Also the false-working one should only have devices (like additional USB-devices) connected which had been used on the working one.
