Are existing wifi clients able to continue sending traffic? It's possible your dhcpd is crashing or thinks it ran out of addresses (misconfigured?). Wireshark may help you there.
If they can't associate to the AP, that's a different problem entirely. If they can't even see the AP anymore, it's possible the wireless driver has bugs. Some of the older N routers had wireless chips that ran very hot and would stop working (early Atheros). Also, many of the early wireless chipset drivers were buggy and would stop working over time all by themselves. Is it running linux? Can you get a shell on it to diagnose things? If it is running linux, the kernel won't ever be jammed with too much data. Any of these little router boxes these days is plenty fast enough to saturate its network ports w/o maxing out the cpu. (unless you've got some crazy netfilter stuff going on w/heavy inspection perhaps) /* PLUG: http://plug.org, #utah on irc.freenode.net Unsubscribe: http://plug.org/mailman/options/plug Don't fear the penguin. */
