When some other device is connected to the network and is for an example watching Netflix my internet is really slow. I've googled and read something about QoS (Quality of Service) which is suppose to solve that problem, but i can't find such option on my router settings. I have Huawei E5172 which is suppose to support QoS according to store4g.com. OR is there another solution to limiting bandwidth allocation of devices. + Is there a way to monitor how much internet is what device using?
