Reddit mentions of Dualcomm Ethernet Over Coax (EoC) Adapters (DECA-100) - Twin Pack

Are you asking, in part, if you can run data over coax? No, don't do that. You won't find switches or NIC's that will support it and you will have to buy adapters like this one https://www.amazon.com/Dualcomm-Ethernet-over-Adapters-DECA-100/dp/B009AGCLVG but why bother?

Use your CAT6 cabling for data and your coax for TV.

I can't answer your antenna question.

I've had incredible results using these https://www.amazon.com/Dualcomm-Ethernet-over-Adapters-DECA-100/dp/B009AGCLVG

Only 100mbit though, but they come in a pair. I used them to run ethernet further than 100m on a farm I was living offgrid at for a while.

Ultimately your choices boil down to telling your cousins or circumventing their wishes in their own home. If you're not paying anywhere near market rate on rent, then "cancer gives you wifi" might just be a passive-aggressive move to make you want to move out because they don't want to say no to you or your mom or something.

It's entirely possible that they really do believe wifi gives you cancer, but if they really believed that, then why have wifi at all? What about the neighbor's wifi? Do they have cellphones?

If they might be reasoned with, then running ethernet or powerline everywhere in the house is one possibility since that avoids wifi, but if you ask them and they say no (possibly because wifi + cancer isn't the real reason) and they don't believe that you're really okay with that, then they're going to be more on the lookout for rogue network devices. Of course, you've already talked with them enough for them to say 'cancer gives you wifi', so they're probably already thinking that you'll try something.

Depending on your usage and coverage at your location, you might look at the cost of getting a USB 4G LTE cell modem, either for your laptop or for a wifi router that supports that cell modem if you have more than one device. Bonus is it's not reliant on their wifi; any other solution is going to stop working when they turn off their wifi at night.

If you can't afford to do that, then any other solution is going to involve stealth, ie buying the smallest wifi router you can find, hooking it up and hiding it someway/how and then you just have to hoping they don't notice it, not to mention it'll stop working when they turn everything off at night. Depending on how messy they are you might be able to get away with it, but the longer you're there, the higher the chances they'll accidentially discover your rogue network device while doing something completely unrelated.

For this, there are a couple choices. You might look at small and USB powered like the TL-WR703N. Get a USB battery, configure the router to be a repeater, put it at the bottom of a moving box, put a pile of books on top, and put the whole box in the hallway and claim you're "cleaning your room" or some BS. Most likely if they even bother to open the box they'll just see books/whatever and ignore it. It'll get you wifi to your room, but it's not really a long-term solution.

If you have access to the coax box for the place, and there are separate runs to your room vs the rest of the house, might be able to use a combination of things to use the coax to get wifi to your room. In a room that has wifi and coax, you configure a router to be a wireless bridge, hook the output of the router to something like http://www.amazon.com/Dualcomm-Ethernet-over-Adapters-DECA-100/dp/B009AGCLVG and connect the other end of the coax to the coax in your room. Then you can hook that up to a WAP in your room.

There are other small router/wifi type devices, eg https://www.ubnt.com/unifi/unifi-ap-wall/ but the end result is still some box that they could easily find if they knew what they were looking for, so even if you manage to find a wireless repeater small enough to fit inside an electrical socket, that's still a device for them to find.

This should probably work, but I do not have personal experience.

Cannot run TV and internet over the same cable at the same time. You would have to switch both ends of the coax cable to accomplish this.

So long as you don't use a coax splitter between them. Here is just an idea of what you are looking for, there are many other solutions, and this is not a suggestion to get, just and idea.

Damn that sucks. This might be a good alternative.

Is it a bare trench? Cause you could pull Ethernet (Cat5/Cat6) though if it is a conduit.

You can totally send Ethernet over Coax, but it is less common for consumer products.

Here is a product:

http://www.amazon.com/Actiontec-Ethernet-Adapter-without-Routers/dp/B008EQ4BQG/ref=pd_cp_pc_0

The second has a higher throughput (270 Mbps claimed) and claims compatibility with normal cable TV signals (e.g. <1000 MHz I'm guessing).

Yes, there are technologies that will let you run ethernet over coax.

(A) It's not cheap: https://www.amazon.com/Dualcomm-Ethernet-over-Adapters-DECA-100/dp/B009AGCLVG

(B) It may not be fast enough for you.

As for finding the missing coax? If you are lucky, then they are hidden within a wall. You might find them by drilling a very small hole in the sheetrock and using a USB camera:
