QoS Vs Bandwidth Limiter

[Catalonia]

Hi there.

 

I've just purchased the router Asus RT-AC88U as we have several devices using internet at home, and I was having tremendous lag when playing ping/critical games and my old router had no QoS of any sort. Since here we have a very bad VDSL ISP, (28Mbps Down 1Mbps up) I wanted to solve the problem, being able to play games while other members of the family can use internet too.

 

Thing is, this router with it's latest firmware: 3.0.0.4.380_7743 is quite a complete package. I know is dual band, but it offers great WiFi coverage,QoS, traffic meter, etc. Ting is, I had my device priorities set up correctly (my RIG is on high priority, and everybody else is low priority) :trollface and I had my router set to Adaptive QoS, prioritizing games.

 

Thing is. Even if a low priority device is playing a Youtube video I get a very noticeably lag, (over 120)... So, I had a look at the traffic meter of that particular device (iPad) and when playing a video it have constant peaks of download (when buffering) so during that specific time my computer can't keep up with the game.

 

So, my guess is that QoS isn't very effective, or for such slow internet I QoS isn't the real solution for me.

 

I tried changing Adaptive QoS to Bandwidth Limiter, limiting the bandwidth of that device to 6mbps down, and a mere 0.2mbps up. Now I can play and I never have lag, not even when Youtube is buffering. The bad news is, this iPad will always be limited to  6mbps down, even when I'm not playing which is a pity.

 

Should I expect this behavior for such a slow internet? (28Mbps down 1Mbps up) or is my router that doesn't apply correctly the QoS settings?

 

Buying a superior router with a faster processor, like the Netgear R9000 would give me a better QoS?

 

Thank you guys!
