Download with Wifi and upload with Ethernet?

Ok, so this is going to be a weird question that I'm asking, if you can't tell already. To start off, I'm in college right now, so I cannot go into the switch room and start fixing the problem myself, and the tech team they have here is about as helpful as bunch a bubbles right now.

When on wifi I get decent speeds of about 150Mb/s down and 20Mb/s up. Not shabby, and I tested it out at 4AM on a weekday, so most people were probably asleep and not taking any bandwidth. But when I connect via ethernet, I only get 3Mb/s down and 500Mb/s up, but it's far more stable, as would be expected in a dorm.

Now, I would like it connected to the ethernet for multiple reasons. Firstly, I upload a lot of large files to a game dev team I work with, so being sure that that isn't capped is a core thing so they get my updates asap. Secondly, I don't want to fight the rest of the campus for upload or download speed when we're all gaming, sending in homework, etc... And thirdly, my "smart" TV wants me to cast most of the stuff I watch like YouTube, HBO, etc... but because of how campus has things setup, I can only do that when they are both connected to ethernet, and with a 3Mb/s download speed, those higher resolutions are taking forever to buffer.

With the campus tech team saying "there's nothing we can do", and me not having access I need to asses the situation myself, I have thought up a solution that might be helpful to my cause. My idea is "what if I could use the wifi for downloading and the ethernet for uploading? This would allow me the upload speeds I need and the ability to connect to my TV for casting, as well as get the extra bandwidth the campus is competing for.

Does anyone have any ideas on how to do this or any better ideas I can do from my situation? I run on Windows 10

It is not something is normally supported.. The wifi and ethernet have different mac addresses so they appear as different devices to the network.

Even if you had full control of the router you would have trouble doing this. You would need to write custom firmware for the router.

You might be able to run both the wifi and the ethernet but they would have to be assigned IP addresses in completely different subnets and then you would have to run some kinds of traffic on 1 and others traffic on the other. It is messy to set up even if you can. If the subnets are the same then there you can only use 1 interface at a time not both.
