I have Buffalo WZR-HP-G300NH wireless router and I updated the firmware to DD-WRT (the newest build). The rest of my home network is in IP scope of 192.168.0.100-200 and this router has it's own. The default IP of the router is 192.168.1.1. On the setup tab (Basic setup) there is a place where I can change the IP, gateway etc. If I set the correct configuration, press save and apply, nothing happens, or actually something happens... I have to remove the WAN cable and reset the modem to access it again. So it won't change the IP.
