I've been having internet problems so my ISP sent over a new router for me to set up. My set up is that I have one computer in my bedroom and one computer in my living room, connected to my TV. I like to share files between them and I used to be able to just go to "Network" and have my two PCs both show up there and I could share my files back and forth with ease. Well when I switched the router, I immediately went into the router, changed all the names and passwords back to the same as the original one to allow all my computers and devices to connect to it as normal. While my phones, Ipads and even two seperate computers have been managed to access the router, and connect to the internet just fine, my two computers cannot find eachother on the network. This means I cannot share files. No matter what I do to try and fix the issue, nothing works, and I'm at my wit's end. Any help would be greatly appreciated. Note: Nothing on the computers themselves changed between routers, and they arbitrarily were unable to find eachother on the Network.
