Furry, I think those are good suggestions, since that type of QoS will work better for him, but I don't think any of those will really do exactly what he is looking for. Since the router would have to monitor bandwidth before it could manager it, probably start there. Does anyone know of any Dlink router with Bandwidth monitoring? I suspect the new DGL-5500 will have it, but that doesn't come out for several months.
Another option is to go DD-WRT, but only if you think your Tech swavy enough. That certainly has what your looking for,
seen here. As for what Dlink routers are compatible, look
here. Of those router, I think the
DIR-825 is your best bet, and is about 74$ on Newegg. There is a thread on these forums
here, and a thread on dd-wrt forums
here and Wiki can be found
here. Keep in mind, this is not supported by Dlink support. It will void your warrenty when using 3rd party firmware, but ALOT of people do it, and its safe if you know what your doing and take your time.
Now if your looking for something with it out of the Box, then PM me and we can talk? Such discussion is not prudent for these boards. Heh. :-)
