Hi! I wanted to ask if there is a way to send most of the connection from my modem directly to my computer, and then send any excess to a wifi router? The only part of my network I need to ever be fast is my home computer, as when I am using it to download files, I basically want to know for sure the whole connection is allocated to the computer. At times when the computer is off or otherwise not downloading, it would be nice to make use of my router, but I want to be certain that my desktops connection is untouched, and it seems like they don't make devices for this purpose... (ie: high quality ethernet, low quality wifi)

Any advice would be absolutely lovely, as I am at somewhat of a loss, this seems to be a feature so called "gaming" routers provide, but I'm not sure if ping reduction is really the same thing as what I am imagining.

Thank you

That’s not how any of this works. Any somewhat modern router/modem combo will not be a bottleneck as far as speed is concerned. Switching and NAT happens in-hardware at speeds that are negligible to your internet speed. There’s no such thing as sending the “excess” internet to another device.

If your router performance is struggling you can get an aftermarket router but you’ll always be limited by whatever speeds your ISP provides.

Do not attempt to plug your computer straight into the modem. It’s obvious you aren’t familiar with exactly how a router works and you’ll be leaving all your computer’s ports exposed to the internet without your router acting as a firewall.
