(I'm not looking for any help with this, Just accepting my fate and moving on.)
Today, I noticed my desktop was loading web pages very sluggish, so I did a speedtest; I only got a little over 1.74 Mb/s down, when I pay for 150+Mb/s down. So I looked at the task tray, and it's saying there's nothing connected to LAN, defaulting to my crappy Wi-Fi. But my Ethernet cable is (and has been) perfectly good. Rebooted the router, switched router ports, and I even recapped the cable with new caps on each end (it's 30 feet), but nothing helped. So I booted Linux Mint 18, and the problem persists... (It appears to load drivers fine and acts normal, but no cable connected.) So it's confirmed to be a hardware problem, not a Windows-specific issue. The router port's LED just flashes an orange light instead of green, and I get no LED activity on the PC side's LAN port at all.

I've taken to using my Wii U's USB-to-Ethernet adapter to bring my speeds back up into the 90Mb/s range for now, but it looks like I just need to spend like $10 on a PCI Gigabit Ethernet card.

Hoped you enjoyed the read.

Orange LED = 100MBit, while you want Green LED = 1GBit. That's your issue right there.

It's probably a router issue. It's not negotiating 1GBit correctly and the NIC falls back to 100MBit because of that. I've rarely seen NICs fail, while it sometimes happen that routers go crazy.

The fact that your WiiU controller works is puzzling though. Maybe it's really the NIC? Weird.

couldn't be caused by the type of cable? in the old days there were 2 types of cable, you needed one type to connect 2 computers and the other for normal routers\switches

Yeah, you're thinking of crossover and straight-thru cables. Nowadays both routers and NICs support Auto MDI-X which means that you can use them just fine.

Actually I was thinking that I might've mixed up Orange and Green LEDs - better check the router's manual...
