Specific wireless router suggestion needed

as far as the monitoring the IP data usage, I think that would be a software deal. I am wondering if iStat allows that. I know that i can see what i am using.

As far as a router, I bought an Apple Extreme in late December and have been very happy with it!

 

I have probably bought a dozen wireless routers. The best performing and most stable one was a Time Capsule. None of them recorded throughput or allowed me to set speed per ip (or total for that matter).

Look into dd-wrt or tomato firmware. As they are created by computer geeks, they will be more likely to include the functions you require than typical equipment targeted at the home user. Each of those firmwares can be installed on a variety of routers.

If you switch up to a business class managed switch, you may be able to do what you require, but you would be looking at hundreds to thousands of dollars for the switch.
