http://unix.stackexchange.com – 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 and this router has it's own. The default IP of the router is 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. Solutions? (HowTos)
