The office has a Sharp MX-M363N scanner/printer hub. Up until recently you could email scans from this hub. There is no server in the office. The internet comes in through Charter and connects to their SMC device. From there it goes to a wireless router (Used to be Belkin, but recently changed to a Netgear N750). The Sharp hub is connected to the Netgear (used to be connected to the Belkin). So when the router change happened all that changed was the IP address for the hub and the Gateway (went from 192.168.2.1 to 192.168.1.1). When I run a test from the Sharp hub, it says I connect to the SMTP sever successfully. But when I try to send a document to anybody's e-mail address I get an error message "CE-00". I have looked this up and it says something is wrong with the DNS. DNS is being supplied by ISP (Charter). In Netgear router, the DNS says being supplied by ISP. Netgear router is doing DHCP. Any ideas why this is happening?
