Hi Top, Anidien beat me to linking the network guide, but you many need to turn on UPnP if you are running 2 systems at once. UPnP stands for Universal Plug and Play. It automatically handles port forwarding and other networking stuff many modern games need to work. Destiny users having problems can often benefit from enabling this if it's not on. Most routers should have it on by default. The exact steps to turn on UPnP vary widely by router. Broadly you should follow these steps. Searching the internet for your exact router model's manual can be helpful. 1. Sign in with a computer to your routers admin page. 2. Look around "settings" and "advanced settings" type pages. 3. Try to locate UPnP. 4. If it's not enabled turn it on. You may have to reset the router. 5. Restart your console
