While I wait, and wait, and wait for Fios to finally be available at my house (they're installing it in a patchwork fashion in DC), I'm getting more and more frustrated by the limits of my DSL connection. In particular, whenever my kids do something bandwidth-intensive on their computer, my WoW latency spikes to near-unplayability. Does anyone know about options for gaming routers that can prioritize certain traffic? I've poked around a bit online, but since I'm pretty clueless on this technology, I'm very confused.

Oh, and I use a Mac; I've noticed some of the gaming routers have the ability to prioritize, but apparently only on Windows machines.

Game Router 5000 of course!

Any router will work in your situation, it will help direct traffic destined to your computer to only go to your computer. It cuts down on some of the overhead.

The main problem you have is more of a "full pipe" situation. If your kids are streaming something, that is a lot of data being sent back and fourth when in comparison, WoW uses very little (although speed is of importance).

The difference between windows and mac on this level is irrelevant.

I would think this is one situation where QoS packet services would make a difference....

IF the problem is the routing, then I suggest one of these:
NETGEAR WNDR3700 Dual Band Wireless-N Gigabit Router

This is a true dual band router, it has two antennae so you can actually have two separate networks in your home. You can also use the "parental control settings" in the router to dial-back the throughput of one of the networks or the other. Then you connect your machine to the full speed network, and the kids to "limited" network... and viola.

You can either run them both as N, both as G or one on each frequency. I actually got this router because (at the time) it was the only one you could get that actually has two separate antennae, so connecting your phone to the "G" network doesn't affect the overall speed of the "N" network (not that I'm sure that makes any difference for anything I do realistically, but hey whatever...)

I think the problem may persist however if the primary issue is that you are simply too far down your DSL line to get the best signal anyway.

Good luck...

Well, I took Hom's advice and got the WNDR3700. While it is working fine as a router (and I think a little better than the lowend Belkin I was using), it turns out that the Live Parental Control feature, which was the main reason I got it, does not have configuration software that runs on a Mac! Nowhere in any of the packaging or product info online does it mention this fact. I am royally pissed (at netgear, not Hom). It's POSSIBLE that I can configure it one time using a borrowed windows machine, and then make changes with a browser, but I'm not sure. Does anyone know anything about this LPC stuff?
