If you want to use QOS tagging, you need to make sure that you 'somehow' get all the packets tagged in your network. It is harder to do than it sounds. DD-WRT routers seem to do it 'ok' but I have yet to solve it perfectly. In my situation, my remote base is at a cottage and it works perfectly unless there is a gaggle of family each with at least 3 wireless devices connected. I has given me lots of real world practice in trying to tune a network in such a way that my RemoteRig is not impacted.
There is another issue that routers today have a problem dealing with, and that is buffer bloat. In a real time application like VoIP, you do NOT want large buffers in your routers as that will actually cause you more problems. Last I check, and it has been some time now, there were no routers that handled buffer bloat correctly. I do believe Meru Wireless (an expensive corporate solution) and Astaro routers manage buffer bloat reasonably well. The moral of the story is to stay wired unless you have to go wireless. A single box of 1000ft of Cat 5 isn't very expensive and provides a much better connection in such a solution. Again, this is from real world experience.
