The challenge is the IP assigned to the modem/router from Comcast is 10.0.0.1 and I just checked whether changing it I would either cause service disruption or it would be reset automatically.
Two things they did suggest were to connect the Base Station in the modem router and see if the printer will connect. I tried that but the indicator light on the base station never changes to green so I'm doing something wrong or it won't connect. Any thoughts?
The other suggestion is to change the SSID on the Comcast modem/router to what is showing on the printer network configuration report and there's change that as long as the password is the same (which it is) it may connect. Thoughts on that method?
No, the 10.0.0.1 address is the router's IP address - the address that the modem uses to communicate to the router.
Comcast does NOT assign that 10.0.0.1 address. You should be able to change THAT in the router settings.
And, that's in the same range as the DHCP server (10.0.x.x). You want to find out how to change the DHCP server range, which is currently set for 10.0.0.2 to 10.0.0.253
Looks like you have to add a second range (10.0.1.0 to 10.0.1.254)
But, I think that's a lot of needless effort, when you should be able to directly connect to the printer, and change the settings through the printer's configuration page - so the printer has an assigned address within the range of the DHCP server.
And, you shouldn't even need to do that, assuming that the printer has a setting that will allow the router to set an address automatically through the DHCP server, for the printer, and NOT use a static IP address for the printer. And, that would be all you need to do, the router would take care of that for you.
If you can't figure out how to connect directly to the printer, maybe you could contact Comcast. I know that will depend on the local Comcast support, but if you are using Comcast's provided router, maybe they can help you with the configuration of a device that you need to connect to their router. I have sometimes been successful with the local Comcast techs, but I know different Comcast regions don't always help with third party devices. Good luck!
