GX20 not connecting to modem

My problem with my first GX20 is that with a direct connection to my spectrum modem it will not operate or connect to the cloud. If I connect it to my existing router switch port it WILL connect to the cloud? I have tried all the resets and reboots and even delete from account and re add. It will never operate or connect to the cloud when wire directly to modem. The lights change colors then go to solid red forever. Any ideas?

Re: GR10 not connecting to modem

John,

 

I'd recommend contacting support, but in my experience cable modems can hold onto DHCP leases of the previously connected device and refuse to issue an IP address to the next device that is connected. Try rebooting the modem with the new device connected if you haven't already. I'd also recommend setting up your first SSID when connected to the existing router and making sure it's set to auto NAT. https://documentation.meraki.com/Go/Meraki_Go_-_When_Bridge_Mode_is_not_Available_(Auto_NAT). The public IP you'll be issued from the modem when connected directly requires you to be in NAT mode, not bridge mode for the SSID.

Re: GR10 not connecting to modem

Got it. I'd suggest setting up through the app with the GX20 connected to your existing router if you haven't already. Connect to the cable modem, then reboot the cable modem. Hopefully that forces the cable modem to release the old IP address allocated to the existing router.

Yep Lee did that many times to no avail. I even left off for 24 hours no resolve.

Re: GR10 not connecting to modem

As a troubleshooting step, what happens if you connect your laptop directly to the cable modem?

John,

 

I see you've opened a support ticket. The support team have access to more tools and information than I do, so they'll follow up with you.
