Prioritize Your Packets
Then, choose High, Medium, Normal, or Low priority, and click the 'Add' button. You may want to set a low priority to things like BitTorrent and other download services, and give your VoIP service a high priority, for example. Note that the Linksys utility also lets you set the priority for specific voice devices, such as VoIP phones that connect directly to your network. Not all routers can prioritize particular applications or devices, but at the very least, turn QoS or WMM on, which automatically attempts to optimize media traffic; this setting is off by default on many routers.
