Cannot Print To Network Printer

I Have a Lanier business printer connect to a modem/router acting as a bridge point that wirelessly connects back to a Dlink DSL2740B modem/router. My problem is that every time I turn the modem of I have to keep setting this connection up again, this never use to happen till I change my ISP last week. I managed to get connection back to the bridge point but can't print to printer, something wrong with ip address I Think/maybe
