Had enough with the lag caused by my family. I have prettly limited upload bandwidth (1 Mbps, downwards is 15 Mbps), whenever they use videochat, or chromecast, or instagram uploading, or whatever, I have massive spikes and ping goes to 100-300 (normally I have 40-60). Unplayable. Generally, I think the main problem is their usage of my precious upload bandwidth.

I heard that QoS settings can improve that, I am currently using sky hub and it doesn't have QoS settings. What's the best replacement option? The price difference of QoS available routes is huge, is there any real difference among those routers? Could you give me some advices?
