I have a Dlink Dsl-2680 from TalkTalk and I need help with all the settings, I need my computer to have the priority over all the other devices that are being used in my house. Can anybody help?
I don't think that router has QoS. Do not mess with the ATM features that are called traffic shaping this is something only the ISP can actually do. You will likely just disconnect yourself from the internet.
get a real router that has QoS, and with the help of your ISP setup your the DLink into bridge mode (modem only) and the router to do the authentication.
