CM1150V, Xfinity -- Google Wifi Not Working
Very odd thing happening -- and Xfinity has been out. I replaced my xFi router with the 1150V. As of now, I am getting a dial-tone just fine, and able to get a connection when I connect my laptop to the modem.
But, here's the rub...
No one can seem to get my Google Wifi router to connect to the network. Have reset the modem, etc. dozens of times. I do have the Google Wifi main unit attached via a D-Link gigabit switch -- could the switch be the bottleneck or the issue? It's making me crazy trying to sort this out!
Just to be clear:
- Phone works
- Modem is visible and connected to Xfinity (agents can see it in the account, reset it remotely, etc.)
- When I connect a PC directly to the modem, it works
- As soon as I try to connect it to my switch, splat!
The modem is in the basement, so a terrible spot for the hub of a mesh system. That's why I need the switch to run it upstairs.
Any help would be massively appreciated!

many devices are connected to the switch? What, exactly, is connected
to what, exactly? Hint: If a device has different types of Ethernet
ports, then "connected to device" is not enough detail.For typical ISP service (which gives you a single external IP
address), you should have only one device connected to your modem. That
could be a computer or a (NAT) router (WAN/Internet port).
What you _should_ do is run a cable from the modem to the router's
WAN/Internet port. All your client devices (computers, ...), including
those near the modem, _must_ be connected to LAN ports on the _router_.
You _can_ connect a network switch to one of those router _LAN_ ports,
which would give you more (equivalent) LAN ports.Such an arrangement might make your cabling more difficult than
whatever you have been doing, but life is hard.- So I connected Google Wi-Fi right to the modem. Won’t connect. Laptop, perfect. Any other ideas?
Thanks for the help!> [...] Won't connect. [...]
I don't know what that means. "Won't" is not a useful problem
description. It does not say what you did. It does not say what
happened when you did it. As usual, showing actual actions (commands)
with their actual results (error messages, LED indicators, ...) can be
more helpful than vague descriptions or interpretations (of what did
_not_ happen).> [...] Any other ideas?
Visit http://netgear.com/support , put in your model number, and look
for Documentation. Get the User Manual. Look for the LED descriptions
and "Troubleshoot". Look for "reset". Further reading might be
helpful, too.Contact Comcast/Xfinity, and ask them if the problem is the MAC
address of your router. Cable companies tend to worry about multiple
devices being connected to a single customer's line, and switching
between a computer and a router might bother them.
Remove the switch between the CM modem and your router. Thats not normal configuration.
CM modem>Router><then switch after the router.
Be sure your CM modem is correctly associated with the ISP service. Have them help you check this if needed.
