Reddit reviews Holland Electronics 3-Way Splitter MOCA Compliant 5-1675Mhz

Hardwire to an access point will always be better than a mesh system.

I was in a similar predicatment to you...3,500 sqft house on one florr.

Do you have cable TV jacks throughout the house? If you do, check out MoCA devices (I Use These). They have Ethernet on one side, and RF jack on the other side. You may have to change out splitters (I Use These) with ones for increased bandwidth. When you connect MoCA devices, you connect them on the output ports (not the input)...also, you have to make sure that you don't have any RF amplifiers in the data as they will not pass data in both directions.

Thanks. Will these work?

You've identified the fix -- using a 3 way splitter as you've described will work. Just make sure the splitter is MoCA compliant and that the tuner is connected to the Bolt via USB. I have a similar setup to you with cable running to modem, tuner and Bolt in one TV cabinet. Only difference is that I'm in a single family home so I was able to run my signal from the street thru a POE filter and into one of these and it has worked like a charm. Not sure if an amp would be necessary or advisable in an apartment setting -- you may be able to get away with a simple splitter

Do you have any particular splitters you recommend? I'm currently using https://smile.amazon.com/gp/product/B00OTO99VY/ref=oh_aui_detailpage_o09_s00?ie=UTF8&psc=1

I tested by plugging a laptop directly into the moca adapter, and running speedof.me and fast.com. Both showed similar numbers. Running them while directly plugged into then router got my normal speeds of 250.
