Well a little info, I've been using my orangepi one with an SDR dongle to track airplanes with flightradar24 for the last few months. My intentions were to use a POE adapter and run the board outside near the antenna at one point. I have now received the final parts and went to move it today. It has been running flawlessly for a month with my POE adapter off of a switch near my PC in my shop. I now plan on connecting it to the main switch on my LAN.
So previously my setup was: Router -> switch -> long ethernet to shop -> swtich -> orangepione
now I want to run it: Router -> switch -> long ethernet to outside -> orangepione
But for some reason this doesn't work, it doesn't connect to the LAN unless it is behind both switches.
After booting it says:
phy: gmac0-0:00 - link is up full/100
phy: gmac0-0:00 - link is down
And repeats this every couple seconds. But if I unplug the ethernet cable and add the second switch between then it connects just fine. My laptop connects fine behind either setups so it cant be the cables.
Any ideas? are there settings in armbian that could be giving me these issues?
