Ok I have three computer all with wireless adapters/cards and can all connect to the internet via my wireless router. Now i wanted to network these computers to be able to share files between them and still be able to get on the internet. I have tried the "Create a new wireless network" and used my USB pen drive to load configuation files on each of the computers. When i do this two of the computers automatically can no longer get on the internet, and I cant find them on the network. My Question is number one, How can i uninstall a wireless network. and Two how can i get these 3 computers networked so that i can transfer files between them?
