is the power supply correct 5V 3A (this source)?

have you tried checking/swapping the cables (It's always right to ask.)?

can you install "ethtool" and check what the command(s) says:

ethtool eth0; ethtool eth1

Have you tried disabling "Energy Efficient Ethernet"?

ethtool --set-eee eth1 eee off

---

the documentation says 5V 2A though!

Thanks! was an ethernet cable quality issue. Changed ethernet cable, now all ok.
