I'm in the market for a router that can effectively limit bandwidth to certain connections (something like QoS, but more aggressive?). It'll be for home use, so no need for server-grade units, just something reliable. It will have a minimum of 2 and a maximum of 4 computers with active connectivity and bandwidth usage at all times. Preferably nothing that requires flashing to DDR-WT or Tomato, since it isn't for myself and more complications means more follow-up support. Recommendations?
