20/30 people on a regular router that has an IP range of 255 IPs will quite often fall over, I've seen it happen more than once.

The issue is mainly that domestic routers NAT tables tend to overflow with that many users on them.

Either this causes them to reboot (if they're crappy) or truncate the table, killing the oldest connection.

Also, that's mostly when you don't tell people "hey, can you not put your iPhones and Android mobile phones on the wireless?"

right, I'm not so sure that's because of DHCP, though.

DHCP pool being exhausted or NAT table getting full are the two main problems I've seen at hackdays
