It's either deal with the distance with a wireless network (which can't even reach my current bedroom in my house) or deal with concrete walls that also cuts down the Wi-Fi signal in my new bedroom.

Then again, my home's network is due for an upgrade because it's 17 years old, so I just need to convince my family to upgrade to CAT6 cabling and a faster Wi-Fi router.

Do people not know power line ethernet adapters are a thing? Look if up on Amazon, you just plug one into the wall by your router and one next to your PC. Clean and strong connections.

Ok serious question I just picked up this Ethernet splitter and I was hoping to split pre router in an effort to bypass the router and bump speeds slightly. Is that actually going to work or am I just dreaming?

They let me go in the attic and run the internet line into my room (it was a 75ft cable). Now we use 5G, but are planning direct fiber once our city halves cost for service.

In college our apartment had one long hallway with all the rooms coming off of it. The connection for the router was on the opposite end from my room. So me and another guy had a horrible connection. We macgyvered a bunch of Ethernet cords using cheap couplers from Amazon and just laid them down in the hallway and into my room. We used an old router as an wireless access point. It may not have looked nice, but it worked!

run the cable to a switch make it so 1/2 the house depends on it, after enough time youll justify doing it better

I did the same. In fact, the PC I built doesn't even have wifi.

Mine runs from the top floor all the way into the basement!
