Hi. So I have recently been bit by the ethernet bug and would like some opinions on how my network should be structured. Our modem and router are on the top floor of our 2 story house. Everything else is in the basement. My objective is to find an alternate solution to running ethernet straight through the living room, which is what I'm doing now. Drilling holes in anything is not doable. When our house was built the electritions wired cat3 for phone and coax for cable tv to basically every room. All the coax and phone lines go down to the basement right above all my servers. I was originally going to disconnect the two cat3 cables in one of the adjacent room on the top floor and use them until I realized they are only capable of 10mb/s :'(. Then I found an ethernet to coax adapter on amazon. My plan is to use a coax jack in a room adjacent to the router to run directly downstairs. Since that room doesn't need cable tv, Ill probably disconnect it from all the splitters so It's a straight line downstairs and has minimal interference. The adapters I looked(Actiontec Ethernet over Coax Adapter Kit for Homes without MoCA Routers) are only capable of 270 mbps. I'm worried that this will cause a bottleneck between phones connected wirelessly to the router and everything connected downstairs, such as my nas and plex clients. I also have my nas connected to the switch using nic teaming so I'm getting 2gbps. I found a startech adapter on amazon that said it was gigabit ethernet capable. But those were double the price.

Sorry for the long post but ultimately here is my question. Should I spend $240 for the startech adapters of get the actiontec for $120. Is there any flaws in my plan. Thanks in advance!

Will post network typology below.

The cat3 idea wouldn't have worked anyway - cat5/6 is twisted much more tightly than cat3.

Still, if you were considering using the cat3, does that mean there's a straight run of cat3 from one room to the basement? Would it be possible to tie cat5/6 to it, and use it to pull the new cable down? Or if some of the coax is a straight run between the two rooms, you can use it to pull new cable down. Other ways to get cable down is along the corner of a laundry chute, or inside HVAC ducting.

If you hire a...
MOCA adapters or powerline adapters may work - it would be better to have an ethernet connection (this is 100% reliable)....and one thing to remember about MOCA and powerline adapters - they don't give you 100% max connectivity they advertise. So if they say 270Mbps, you will get a portion of that - but never 100% of that....and depending upon the quality of the cable and potential interference with the cables, it could be dramatically less.

You can give it a shot...worst thing that happens is that it doesn't work....For $300 you can probably have a professional come in and install an ethernet cable(s) in your home to resolve the problem....

I was thinking of doing that. The only problem is most of the wirless device would be on the middle and top floors. So I would probably end up having to get a ubiquiti access point that supports ac which would be expensive, and I would still have to run some kind of cabling up to it.

I may end up hiring an electrician but I'm not quite sure how he would be able to run a wire upstairs without destroying any walls. I have searched the house up and down for a cranny to fit ethernet through, but to no avail.

If you hire a professional, he should have tools which allow him to drill through the horizontal beams the cable will encounter inside the walls (basically a drill bit on the end of a long wire). The only damage to your walls should be a small hole that you're going to cover up with a wall plate anyway.
