Viewing the bandwidth usage of a wireless device connected to my router
I just want to figure out which wireless client is sucking my bandwidth (it's slowing down my Starcraft games :-/).
I have a Linksys WRT54G router (Linux version). For firmware, I'm currently using Tomato but I'm
willing to consider a different firmware. Anyone have recommendations?
PS: I'm aware of Bandwidth graphs in Tomato. However, it is not granular enough to give me an idea of how much bandwidth each device is using

As you look for tools, remember that you're looking for who's using the most airtime, not who has the most throughput. A client getting 500kbps of throughput using the 1mbps data rate is hogging much more airtime than a client getting 5mbps of throughput using the 54mbps data rate.

Only the paid version of DD-WRT has granular bandwidth monitoring. All the free versions just show graphs on current usage for the WAN, LAN, and Wireless network interfaces.

It seem that tomato with iptables can be used as bandwith monitor. detailed instructions

I do not understand why you cannot selectively block clients from the network, until you empirically find the guilty one.
If you are looking for a more high-tech method, you may try using a packet sniffer, also called packet analyzer, to analyze all traffic on the network from your computer instead of from your router.
A packet sniffer can capture packet information within its subnet, even if these packets are not addressed to your computer.
The feasibility of this method depends on the behavior of the router and whether it broadcasts all network packets or not. Wireless networks are of course much easier to snif than wired.
See this article, Free Packet Sniffer Software, for a list of such products (not all are available for Linux). The best known sniffer is Wireshark.
