I have spent 7 hours now trying to connect to my Neo3 via my PC using a USB to Ethernet Adapter.

Is this actually possible? Can I plug my Neo into my laptop with a ethernet usb adapter? or does it have to be into a router?


Ive tried changing the nanopi microsd card image to see if it has any effect. from Ubuntu / Armbian / DietPi.
Tried also without the microsd card.


When im powering on my Neo3, with ubuntu only the red led shows, with the other two, the Red LED shows plus the green LED flashes.


The error im getting on my laptop is Connection Failed : Activation of network connection failed.

the network manager shows it forever stuck on Connecting - 1000Mbps


Running cmd nmcli device status returns

Code: Select all

ethernet  disconnected 



cmd dmesg to see if there was any errors, one line read

Code: Select all

firmware: failed to load rtl_nic/rtl8153b-2.fw


this error is for my usb to ethernet adapter, I fixed this by downloading rtl8153b-2.fw into /lib/firmware/rtl_nic/ and running sudo update-initramfs -u



After running dmesg again, another error causing problems could be


Code: Select all

xhci_hcd 0000:00:14.0: WARN Set TR Deq Ptr cmd failed due to incorrect slot or ep state.



im unable to fix this so far, I have tried changing ethernet cables, and also adding kernel parameter intel_iommu=off

The error still shows in dmesg and im unable to connect to my Neo3


Any help?
