CM1000 modem connectd to WNDR4500 router
I upgraded cable modem from a Netgear CM400 to a Netgear CM1000. I contacted Comcast to activate the new mode. The instructions were to connect the modem to my desktop computer with an ethernet cable...
#1. power off all the devices.
#2. power on CM1000 and activate it.
#3. Confirm there is INTERNET by hard-wiring desktop and then remove the laptop
#4. Reboot the CM1000 and then connect WNDR4500 and power it on.
#5. Restore factory defaults on WNDR4500 and check again.
at any point, please DO NOT connect multiple devices behind CM1000 without rebooting. it can ONLY provide 1 Public IP.
Success!!! I contacted Comcast today to give this activation a second chance. This time I had a different rep with different setup instructions. He had me connect the modem to the router instead off my desktop computer to activate the modem. The activation worked and I have internet connections on all 4 ports on the router and wireless connections on other devices. I did not do a factory reset on the router, so any configuration changes I made to the router config were the same as yesterday.
