My internal ip address keeps changing from 192.168.1.100 to 192.168.1.101. This is really annoying since I run a MC server and I have to port-forward my ports each time and sometimes I can't even access my own server! I have a cheap Callisto821+ modem I got from my ISP and a crap D-Link DIR-300 WiFi router I got from the internets. I've got a DSi, Iphone, laptop and a notebook connected to this thing. Can anyone help?
