Lag spikes in games if someone else is browsing

I've got Zen 80/20 which I thought would be more than enough to never see another spike again yet despite this if I'm playing League of Legends and my wife starts streaming something or even just opening web pages and browsing, I get 400ms+ ping instantly and the game just becomes unplayable.

My setup is BT Openreach modem > Asus RT-N66 > Trendnet unmanaged 24-port switch

One laptop is Win 7 connected via AC wireless, her laptop is a 2013 MacBook pro so I think would be 'N'

I've tried going into the N66 setup and prioritizing League in the QoS menu but it made no difference. I've also tried plugging in via Ethernet and it still made no difference - as soon as she opens a youtube window, streams something or just loads a webpage I get an immediate massive lag spike and the longer she accesses the connection the longer the spike remains

I can't understand why an 80/20 connection would struggle to deal with 1 streaming connection and 1 online game? Am I missing something?
 
Firstly, what's the switch doing?

So both laptops are connected to the Asus WiFi, and you get problems in games over WiFi and ethernet, while the other laptop (macbook) is using the Asus WiFi, correct?

Have you got a different AP you can try instead of the Asus? Or alternatively, try plugging her laptop in.

I'm wondering if high WiFi throughput from the Asus is overwhelming it.

The switch is just providing network access to all the Ethernet ports in the house - currently only living room TV and NUC are making use of this. The rest of the ports are unused.

Yes both laptops are connected to the WiFi, same network etc. Unfortunately we cannot plug the macbook pro in by ethernet as it doesn't appear to have a physical ethernet port

I don't have a different router than the Asus I'm afraid - but not sure I'm following what you mean by high throughput from the Asus.

Well my thinking was
  • it might be the ISP but you have no control over that apart from switching provider
  • you can't easily replace the modem
  • it's probably not the switch
leaving only the Asus as a piece of the puzzle you have some control over. I was wondering if maybe when the macbook is hammering it it can't keep up and introduces a load of latency on your gaming traffic. But if you've not got anything else to test then there's no way of knowing that I can see.

Maybe someone else has more experience with these Asus routers.
 
Stuff like video streaming tends to buffer up segments of video at full speed which will have some impact on the connection - rate management and/or QoS can mitigate that but sometimes it can be complicated to get QoS working correctly.
 
Ok but surely there must be a way to 'share' such a fast connection (both up and down) without having these issues that doesn't require professional QoS management? I

t's like im back on ADSL 1mbps - there's literally no point in such a fast connection if it cant handle even 2 connections at the same time without loss of service to one or both
