We just switched our phone and internet provider from Verizon FIOS to Comcast Business, and Comcast provided us with a Cisco DPC3939 modem/router. We have had an issue connecting our Epson WF 7510 wifi printer to the network. When I go through the printer wifi set up, the printer says its connect to the network but it's not visible on any computers. The printer diagnostics say that it's connected with a IP address starting with 169, a subnet mask address matching the router, and a default gateway address of "none". Epson says that the IP address is incorrect and is being assigned because it cannot establish a connection with the router. They say the IP address should begin with 192 or 10 (the router address begins with 10, so that makes sense). I logged into Comcast's gateway and it shows the printer connected and having an IP address starting with 10. The other odd thing I see on the gateway is that all other devices on the network are connected via DHCP, but the printer has a reserved IP. I've been on the phone with a few people from Comcast and they point fingers at Epson and vice versa from Epson. All of our other wifi devices are working fine. Is there any reason these two are not communicating?

strange that the gateway says that it is connected, but the printer itself has a 169 address, which means it's not (it failed to receive an address from the gateway, is what that means.)
have you tried setting the printer with a static IP? usually this can be done from the printer's menu or potentially via software on a computer. you should make sure that the last number in the address (e.g., 10.0.0.x) is outside of the "range" of numbers listed as being available for DHCP. you would find this information on the gateway's configuration screens. (haven't worked with this gateway, but i believe it has a default address of 10.0.0.1. Or maybe 10.1.10.1)
I know this is a little older thread, but wanted to respond for the benefit of those who may come behind. Many of the consumer grade all in one printers are set in their configuration to "Auto" when choosing connection type. I have found that by simply changing this to DHCP that the printer will grab it's IP address from the gateway and problem solved. I have seen this on Epson and Brother Printers regularly.
