Have just installed a netgear DGN1000 DSL modem/switch. Have assigned it an IP address other that factory original. After initial configuration, I can get on the internet just fine. But during next day start the DHCP assigned an IP address to the computer a gateway different than that of router. I have to go to CMND prompt to release and renew ipconfig to successfully get a correct IP address/Gateway to I can get on the net. how can i fix this?
