I will try that now 
I have put a netgear unmanaged switch in between and put the POE swapped cable in LAN1 and a normal UTP CAT6 cable in LAN2 on the switch and the WAN port on the Peplink router.
IT WORKS
So a valuable leason learned here, you cannot connect directly to a Peplink device from a POE when you need to swap blue/green cables towards this picture below on the outgoing side of the POE you have to have a POE with a non swapped cable.
nice! so working well now?
FYI probably unrelated but check out 6:10 of this video https://www.youtube.com/watch?v=RlENmAikSQQ&t=0s Where he talks about bad crimps.
Yes it was the port flapping, you put me on the right track with these words. Many thanks as this is a great beginning of 2024
It also explains why it worked perfectly on the old RV router which did not matter the swapped UTP end on the data side of the passive POE.
So the cabling and Chinese POE and Chinese step up inverter worked fine, it was the non supported cabling by Peplink.
I also watch his channel, but that device is too expensive that DC-DC converter and to get it to the Netherlands I would pay around 150 euro excl. vat and custom duty, so it might even be more expensive.
But this 12v-48v 3A inverter I have works fine also it is waterproof which this Canadian product is definitively not.
Regarding the bad crimps in another video of him he has incorrect cable information, I need to inform him about this
Also you can overcome this partly on the cable crimps between the POE en Router by using a cable tester. You can not test this on the propriety Starlink cable to the dish there you have to rely on and use open RJ45 crimping plugs to validate the right connection and make sure you are crimping correctly.
Yup it is expensive, but still pretty slick. Several different ways to accomplish the same thing.
Yeah I would hit him up on the incorrect wiring.
yes you dont swap the cable order on the outgoing side of the poe.
also my comment still stands about getting a better power source. you want clean power closer to 50-56v IIRC. I am using victron 24v to 48v that is adjustable to 56v.
@Jonathan_Pitts & @Chris_Boer : I’ve been following you as you worked through this. Nice job on the troubleshooting. Kudos! Quite a saga. ;<)
Thanks Rick! I enjoy a good wire/voltage/networking hunt.
I don’t have 24V but 12V, also there is no Victron 12V - 56V DC-DC converter but there is nothing wrong with the hardware nor the cabling itself. Also you only need the higher Watt output for the heating of the dish and that is not required over here, also the inverter I have is 48,3V 3A and that is enough.
And you do have to Swap the cable order on the outgoing data side with this passive POE like the one I use if you use yaosheng you overcome the need of swapping as this is done inside of the POE so you overcome the issue with the proprietary Starlink hardware UTP connectors.
The issue is/was that the Peplink does not accept the swapped cable and starts port flapping, while other routers do work Netgear/TP-Link/my cheap RV router.
Thanks Rick ! It was basically the wording of @Jonathan_Pitts in post 14 where he said : Perhaps it’s port flapping ? So that was the trigger for me that this had to be the solution, and it was !
i disagree with you, i have done or helped with several starlink installs, and the top issue seems to come down to power, and people using the power converter like you are. there is another company, mean well, that makes 12v to 48v. you might get by, you might not, but i know folks have had performance and reliability issues using the cheep dc to dc converters like you have. this has nothing to do with snow melt mode. and if you stick with the cheap one, go up at least 1-2 sizes, they dont last.
I just checked Mean Well but they only deliver 0,6A output which is to low. But the yaosheng POE is on its way so then I can remove the switch and swapped cable and replace it with a CAT6 UTP.
