Routing myself into internet superiority

[Ziek88]

Unlikely you'll be able to find a router that does that for under $50 and the "flip a switch" part is even less so. You can set priorities in high quality routers but you won't be able to change those without logging in to the router and changing those. I suppose you could attempt writing a script but I'd imagine not all routers will be able to take that or at least make the changes fast.

A much easier solution is a better connection. Figure out where your bottleneck is and then upgrade it.

I can run a PS3, Xbox 360, 3 Laptops and a Desktop computer all at a fairly high internet usage without so much as a hiccup. I'm lucky now with a 50-60 mbs download and 10ish up but I've had 20 down 2-3 up in the past and was equally fine. Try going to Speedtest.net by Ookla - The Global Broadband Speed Test and see what your speeds are. If they are decent you may just need a router with higher speed ports and wireless capability rather than messing with priority and that you could do for under $50.
