Looking at getting a new router modem and thought of the Asus dsl ac68u. Now we have multiple devices in the house streaming HD content so this would be a good option. Only problem is that my internet speed isn't that great. It's 6.5 to 7 megabits per second. Now of course I know this router handles speeds way way greater then that but would it be a good option to use so that Internet speed doesn't slow down when multiple devices are being used? Also will it maximise Internet speed?
