Hi David-

Yes- this is the setup. I'm on Primus internet in Canada, and assumed that the TP-Link was functioning as a Wi-Fi access point for the modem, however I see now that it is working as the main router.

Oddly, I found out the RP3 has NO internet access, while the TV does. I can also project to the TV from the Laptop, or phone. I have switched the RP3 to wifi, and it seems fine, but to minimize wifi traffic I may switch to AP mode on the TP-Link and see if the Modem has router capability and DHCP set up that is user configurable.

Thanks,

Brennan
