i have comcast cable internet. i want to install another mac 200ft away in another building. i need a wired router/gateway…(so i was told). i’m a complete novice in these matters. i bought 200 feet of cat5 cable to see if the internet stream would travel 200ft to my destination and it worked. now i need to have the precise names of companies and or precise names of what gear i need ie….router/gateway, and in what order to use them. any help would be great and i thank you in advance. frank
