Hi!
I’m using hAP AC with latest stable firmware. I have a 100Mbit link on ether1 with ISP by direct cable. My setup is a plain default “Quick set”.
The problem is that when somebody at my home runs torrent and the speed reaches 100Mbit all other devices are losing connection to the internet.
I tried to google but… Is there a simple solution or I should dive into queues and p2p traffic marking?
Thank you.
Queues are simple solution 
I’m not an expert, just want to share my mangle & queue according to http://forum.mikrotik.com/t/using-routeros-to-qos-your-network-2020-edition/66683/1 and with a little experiment
My connection UP 1.3Mbps, DOWN 10Mbps, WAN ether1 and LAN ether2-master, RouterOS v6.38.7
Just simple explanation:
- Mark traffic (VOIP, DNS, ACK, HTTP, UDP etc). we need for assign priority for each traffic
- First 1MB will get full speed burst 1s (with this I can get 14MBps) - if HTTP, my assumption as BROWSING - using SFQ for this so no one feel connection down
- After 1MB, if still using full speed (or anything that using very much bandwidth) , mark as DOWNLOAD - using PCQ for this, so everybody get equal bandwidth if they are downloading
- At Queue for each traffix set limit-at according max client, max limit to set how much bandwidth for this traffic, example for HEAVY traffic you can set max-limit 80M so you have spare 20M
I thing these code for you with connection 100M. You can modify like what you need
