Need help with in home networking

Good morning! I'm a networking novice, so I'm sure there's a simple answer. I'm trying to set up my in-home network that already we newly hardwired cat-6 throughout the home. So to start, I have an Xfinity cable modem, Netgear CM1000. I've hooked that up into my TP-Link SG1016DE which is a 16 port switch. Then inside the home, I've connected on one of the ethernet ports my main Google Wifi puck. That works perfectly, and meshes with the other two pucks and provides great wifi speeds. However, whenever I plug any other device direct into any of my other ethernet ports, there is no internet connection. 

Is it the switch, an internet setting? What am I missing? I've googled and googled but cannot seem to have a good grasp of the technical terms to really find a similar situation and solution. Thanks in advance!

The primary puck acts as a router (NAT, firewall, DHCP). Thus the switch should come after the Nest Wifi primary, not before.

Currently, when plugging another device to the switch, it gets directly exposed to the internet (not good), and probably gets your one and only WAN IP.

Also, Nest Wifi has it's own loop protection mechanism, STP (spanning tree protocol). Make sure you disable any such functionality on the switch.


I don't work for Google.

As mentioned by olavrb, make sure your modem is connected to the wan port of the primary puck, and then connect the other network port on the puck to your switch. 

I had a similar connectivity issue where my devices connected to the switch were not able to be identified by anything over wifi. I changed the cable connecting the primary puck to the switch from a cat6a to cat5e, and all my problems went away. No idea why, but I read something similar in another thread here. It's still 1GbE, so no harm done. Maybe give this a try, since it is a cheap option.

Thank you everyone for your help in clarifying. It’s weird as I’ve plugged the modem to the main google Wi-Fi puck, and then from the puck to the switch. But all Ethernet ports still won’t get internet connection. The connection is detected by both computer and on switch via the green dot, but it still won’t get an IP address to get internet. Arrrghhh

Hey song510,

 

This one remains crazy, I see. I did want to double check something that olavrb mentioned, however. Did you ensure that STP is disabled on the switch so that the Nest router handles that alone?

 

Thanks,

Jeff
