We are a family of 4 and sometimes we download windows updates in the background on our PCs, stream a YouTube video, or download a game. How do I make sure this does not effect the streaming tv without interruption or lowering the quality of the stream please ? Of course we all have more than one device so yeah. We already have a good router. ASUS RT-AC5300 Tri-Band Wireless AC5300 Gigabit Router. This router is good enough right? Our internet tier we pay for is 50 Mbps download and 5 Mbps upload but it is more like 60 Mbps download and 5 Mbps upload. Is this enough for 4 people with multiple devices with streaming tv exclusively or do we need to go up a tier ?
