I live in an apartment above a store that provides my internet connection. Downstairs in the store there is a router which I'm fairly sure does not support gigabit internet. The wifi is atrociously slow, however I aim to fix this by connecting a cable to the modem directly to my computer. It should be noted that we receive 100 mbps on speedtest
I've delved a bit into how ethernet cables work and noticed that non-gigabit internet only uses two pairs. This brings me to my first question:
Is there a way to make it use two pairs for the router and the other two pairs to my computer, so that both get their individual 100 mbps?
I was also looking into splitters, but I'm not sure if they work the way I think they do. I've thought about using two tiny cables from the modem downstairs, use a splitter to get a single output, hook that up the existing cable upstairs, then split it off again using one ethernet cable on my PC and the other on the router. I realize that the purpose of a router is routing the internet off so I could just stick my PC's ethernet cable in there instead, but that would mean wifi and cabled internet have to share the 100mbps, (which is something that I'm trying to prevent).
It should be noted that the modem downstairs does not use any of the modem output ports.
Any help is greatly appreciated! If any additional information is needed, please let me know.
