@jasoneer check the pins inside the RJ45 port, one of mine wasn't working because the pin was too flattened, I bent it up with a toothpick and that fixed the issue.

Was really in a crunch on this one and needed to get it working, so I ditched OnionOS all together in favor of vanilla OpenWRT 18.06.5 I followed the first two steps here https://yoursunny.com/t/2019/omega2pro-openwrt/ I removed the -F from the command as it is not needed in my situation. I then had to locate and specify the correct file path. Within minutes, OpenWRT was running flawlessly on the Omega2+ I connected to my home network Wifi AP and disabled the Omega2+'s access point by selecting "replace current wireless etc etc" I then followed instructions here https://www.circuidipity.com/openwrt-bridged-repeater/ for bridging the wifi through ethernet which worked flawlessly upon the reboot. I now have the BeagleBone Black (powered via 5v adapter) connected to a USB hub, which powers the Omega2+ as well as connects the Beaglebone to the webcam and 3D printer. Test print is running now to see if the timelapse renders, which was the issue with running Octoprint on the Omega2+ directly; the timelapse would be captured and visible in unrendered timelapses but would crash the Octoprint server at any attempt to render. The other motivation for switching was to get away from the baud rate limit on the Omega2+ which required me to run custom firmware on my TAZ6 as default firmware all runs 250k baudrate due to performance issues with 115.2k. Hopefully this helps someone else in a similar scenario. tl;dr for Onion developers: Your documentation is inaccurate and/or out of date. Had I been able to use the Onion Omega2+ as a Wifi to Ethernet bridge as described by your documentation I would not have had to ditch OnionOS/firmware entirely. Please update your documentation so that a person could, if desired, use the Onion Omega2+ as described, out of box. After working around the shortcomings of the device & documentation, I am pleased with the performance of the hardware using plain OpenWRT 18.06.5 Cheers!

@jokre take a look at udhcpc this is dhcp client tool under BusyBox.

same problems but after the last firmware update... i never had a board with so many issues....

I guess this is no easy task with the omega2, perhaps impossible?

@Filipe-Madureira Yes, as expected. Onion's Ethernet Expansion provides only wired 10/100 network connectivity via a standard Ethernet cable. Power over Ethernet Power over Ethernet or PoE describes any of several standard or ad-hoc systems which pass electric power along with data on twisted pair Ethernet cabling. This allows a single cable to provide both data connection and electric power to devices... Here you are an example Omega PoE Dock I think this dock is too compact, too complicated, too expensive. If I remember well @luz has made a nice custom dock with (P)PoE capabilities - with an appropriate Ethernet jack and some ~5 .. 39V to 3.3V (or 5V) voltage converter. Unfortunetely I can't find this post.

I know this topic is quite old, but did anyone succeed in making eth0-4 work on the Omega2S in the meantime? I am just wondering, bc all documentation on the Omega2S i found so far only mentions 1 ethernet port - if it supported 5, why not say so in the docs? Of course the datasheet of the MT7688 clearly specifies 5 ethernet ports in IoT gateway mode, so why not in the Omega2S documentation?

I was having similar issue, then I tried to use omega as a router from below link: https://docs.onion.io/omega2-docs/omega-router.html It is now working fine for me, and ethernet is getting IP by dhcp. But I also need a static ip on ethernet, so if in any case, dhcp is not working, it should be having the static ip. I tried to create one more connection name as 'eth1' with interface as 'wan' as below: config interface 'wan' option ifname 'eth1' option proto 'static' option ipaddr '192.168.0.233' option netmask '255.255.255.0' option ip6assign '60' But it is not working and one more interface 'eth1' is not being created. I tried with using interface as 'lan', it is also not working. Can anybody tell me how it can be done. Again, my requirement is to have a static ip on ethernet, in case dhcp is not working.

@Shashi-Alabur Since you can connect via SSH, if you are working in Windows then take a look at WinSCP, Onion has good instructions here. WinSCP enables you to use your familiar Windows editor with the Omega's files. Re the Onion Console not connecting - try using another browser - Chrome or Firefox or try clearing the cache in your browser. If these fail, maybe time to factory-reset or update firmware.

@Guest Hi, Thanks for explaining in detail. Is your tutorial will work for: Changing network priority between Ethernet and WIFI. Ethernet need to be at 1st priority. WIFI needed just as fallback network, If ethernet not working then search for WIFI connectivity
