Hotspot network does not the same network mask

I have all of my computers wired to a network and they can all ping each other. The router does not have wireless capabilities and I would like my phone to be coected to that network so that I can coect to the computers. I created a hotspot on my computer in hopes that I would be on the same network but the IP address of my phone does not match the ones the network with the computers have. I'd like my phone that can't be wired to be with the wired coection so that it can coect to my computers that on a wired coeciton.
