I'm having slow speeds

[rabbitrider1]

Hello, I currently live with a couple buddies and whenever my friend I play any sort of game online while another person is watching Netflix we get serious ping spikes and lag. We currently Pay for 50 mbps but we normally get 20-30 mbps while connected with an ethernet cable and sometimes it will down to 15 mbps. Would using a router that can switch between 2.4ghz bandwidth and 5 ghz make a difference? Right now for router and we have a modem that works as a router also. The only other thing I can think to do is upgrade our internet to 100 mbps but I'm not to educated on networking. So basically what I'm asking is how can i get it so we can play online and watch netfliz with no lag?

The ethernet cable should be able to handle 50mbps. That's about 6.4MB/s I think.

That's creepy. What kind of cable do you have plugged in? I have a 100 mbps line and there's never >10 mbps difference when I test the output.

I assume you're all connected through cables so a router which allows both 2.4 and 5 ghz bands will not make a difference since it's wi-fi. But if you're on the hunt for a new router then I would highly suggest getting a router which offer dual band capability.

50 mbps should be enough for both playing online games while streaming Netflix at the same time so I'd wait with changing to a 100 mbps line.

Its really weird because at my parents house I get 20 mbps and can play games and stream a video just fine. Im thinking that our modem/router combo is our problem.

Are you all connected through wi-fi or cable, or both?

[rabbitrider1]

The modem that we currently have is the Arris DG860 (wireless)

We're connected with an ethernet cable  if thats what you're asking.

Do you have any other router at your disposal which you can test the connection with?
