Printer not printing from LAN after Google Nest Pro installation (mostly solved)

[prf_thornton]

I was not able to print from the LAN to the printer after Nest WiFi Pro mesh install since the wireless printer joined the new mesh network, the install had no general issues and the coverage is fantastic but was not able to ping or print to the printer after nest installation (due to IP update and seemingly not able to cross IP through the main LAN / WAN . I saw an old thread that stated to feed the internal LAN through an unmanaged hub off the main Nest unit which solved the printer access and general LAN issues since that put the remaining internal LAN on the Nest IP ranges.  The ISP is a Comcast modem and I can longer get to the modem through the LAN now for admin and support (via browser from the LAN) since the LAN now has IP's from the Nest mesh setup.  All remaining systems seem to be working as expected thus far but just installed the nest a day ago so still testing.  Any suggestion on being able to get to the ISP modem and the original IP?  (not sure that will be solvable)

Hello @prf_thornton,

Thank you for providing detailed information about the network changes and issues you're experiencing after installing the Nest Wifi Pro mesh network. I appreciate your effort. I understand the frustration of losing access to your printer and the ISP modem after the setup. It seems the new IP addresses assigned by the Nest WiFi system are causing conflicts with your existing network infrastructure.

To effectively troubleshoot this issue, please provide the following information:

• Printer Model: Please specify the model of your printer.
• ISP Modem Model: Please provide the model of your Comcast modem.

While I gather more information, you can try the following steps:

1. Check Network Settings: Ensure that the IP address settings on your printer are configured correctly. You might need to manually assign a static IP address to the printer within the same IP range as your Nest WiFi network.
2. Disable DHCP on the Modem: If your modem allows, disabling the DHCP server might prevent IP address conflicts. However, proceed with caution, as this might affect other devices on your network, if you don't know how to do it, contact your internet service provider for further assistance. 
3. Contact ISP Support: Reach out to Comcast to inquire about potential network configuration changes or limitations that might be causing the issue.

Please let me know how it goes. Thank you. 

All the best, 
Jorge
