I was doing some cable management on my network setup and accidentally unplugged a few Ethernet cables. Now, I can't seem to get internet access back. I'm looking for guidance on where to connect the Ethernet cables from my PoE injector. I've tried plugging a yellow Ethernet cable into the Data In slot of the injector to the WAN port of my router, and also connected the Data Out slot to my switch and router. The injector model is POE-M911-N, the switch is a NETGEAR GS316 16 Port Switch, and my router is a Tplink Archer Ax 55. I can't even find the modem since it's installed in a wall insert. Any help would be hugely appreciated!

Here’s the picture you asked for! I’ll clean it all up and put a panel on it once I sort out the current wiring issue. https://preview.redd.it/btd16z36btbg1.jpeg?width=3024&format=pjpg&auto=webp&s=04ed00e859b8d4275babc7a8311e5a3d6046b2a4. By the way, the yellow Ethernet cable is a crossover cable, which used to be common for direct connections between devices but is often unnecessary with modern equipment that auto-senses connections.
It might help to have a diagram of your network setup to better visualize where everything connects. Do you have anything like that?
Once you get everything working again, it might be a good idea to label each cable's ends to keep track of where they go. It’ll save you trouble in the future!
