Wireless Router Issues

I upped it to 250 maximum users, but we started running into issues with the Wi-Fi just dropping out of existence (no one's device could find it). We had a few things hardwired into the router, and they continued to function normally. We had about 70-80 DHCP entries around this time.

Is the issue with the router handling too many DHCP users? Would running the DHCP server on a computer behind the router, thus making the router function only as a access point/switch? Or can a WRT54G absolutely not handle this traffic load?

Is there any wi-fi system that is more powerful?

Generally, more than about 25 associated clients on a single access point will start to lead to problems. This is true for higher-end AP's as well. The number of DHCP entires or MAC entries are unlikely to be limiting factors.

You might see a somewhat greater number of simultaneous users if you run in G only mode.

If you want to increase the number of connected clients, you could run 3 access points on the non-overlapping channels 1, 6, and 11, and route them on the WAN side of the 3 WRT54G's.
