I am currently sharing files between two computers through the router wirelessly. On computer 1 I have all of my important videos and pictures for my home videos. I have back-up software copying my files to computer 2 over the network as a back-up. This back-up plan seems to work fine but it is painfully slow. I only get about 8mb/s transfer speeds with takes hours to upload changes. My plan is to run an ethernet cable from both the computers to the router to increase the speed to about a gigabit a second. Will this work to hook both computers up directly to the router to get internet access and file transfer over the same ethernet cable? And is this safe, can others access files through the internet. Do I need to buy an isolated switch for better encryption? Just wondering what the best way to do this is. Thanks.
