RAX40 gets DCHP IP Gateway & DNS but can't ping cable modem
I am replacing a WNDR5400 with a RAX40. Both were connected to a Netgear CM1000 cable modem which is served by Comcast/Xfinity. I did the RAX40 setup with my Mac connected to the RAX40 via Ethern...
While awaiting the return level 2 support call from Netgrear, I solved my problem. I did another hard reset of the router, but this time I configured it using the iPhone app. Previously I had dont the configuration with a web browser connected to the router with an Ethernet cable. This time, it worked. I noticed one change in the configuration: when I had the problem, the Router MAC Address in Internet Settings had defaulted to "Use Computer MAC Address". The Netgear level 1 support tech I had talked with said that was the correct option to use. But when configured using the iPhone app, it is now set to "Use Default Address". I'm not sure if that change is what fixed the problem or not.
I am also happy to report that I did get a call back from a level 2 tech within 2 hours, but I had already solved the problem by then.
It may have been simply a case of resetting and rebooting the whole network in the right order.
You can't just swap out one bit of hardware and expect everything else to cooperate.
Be sure to restart your network in this sequence:
- Turn off and unplug modem.
- Turn off router and computers.
- Plug in and turn on modem. Wait 2 minutes for it to connect.
- Turn on the router and wait 2 minutes for it connect.
- Turn on computers and rest of network.
