Xfinity Flex stuck on Welcome Connecting to your entertainment experience
I recently received a Flex streaming device when I subscribed to Xfinity Internet service. The Flex box worked fine when the installer first configured it to connect via WiFi to the Xfinity-supplied Gateway. I have since purchased a Motorola MB8600 cable modem to replace the Xfinity Gateway. I have the MB8600 feeding a Gigabit Ethernet router, which provides DHCP, NAT, etc. for a wired Ethernet network that runs throughout my house. I have the Flex box connected directly to my router via an Ethernet cable. Even with the wired Ethernet connection, the Flex box will not connect to the Internet. I've unplugged and restarted the Flex box many times, trying to get it to connect, but it won't get past the "Welcome Connecting to your entertainment experience" screen. It eventually lands on a error screen with error code RDK-03117. When I check my local network map, using my router's management GUI, the Flex box MAC address does not appear in the list of connected devices. This leads me to believe the Flex box is not joining my local network to begin with, so I can't even ping it, let alone connect it to the Internet. BTW, I also tried to connect the Flex box via WiFi to my in-home Access Point, but I got no further than I did with the wired Ethernet conection. Any suggestions for troubleshooting would be much appreciated.
