So me and my roommate both play the same games together and we were using a 100mbps speed with the basic modem/router combo that came from our ISP. We upgraded to 400mbps and they gave us just a modem so we bought the nighthawk r7000 ac1900 router. So before when we were using the combo unit on the low speed we could play any of our games together without any connection issues but some ping issues from time to time. Now with the new router and speeds we have a lot of connection issues when we try to play the same games. We have tried UPnP and port triggering and stuff like that and it helps for some games but we still have connection issues in a lot of other games and we never had any of these issues when we were using the combo unit. So my question is, is there a setting or new router that allows multiple PCs on the same network to play the same games like our combo unit did, or is there something special about a modem/router combo that allows this to happen? We just want to be able to play games together again without fighting with the network issues.
