Recently, my computer has decided to use less network. previously, it used about 70mps and suddenly wont use more than 15mps. I run a server on the machine so I need good internet. my internet plan is 80mps and we own a century link router. my computer uses WIFI, but its in the same spot as it was when it worked well and when I use my laptop in the same place, it uses 70 mps. how can I get my computer to use more network when it needs it?
