I have a wired device (Samsung Smartthings hub). I want to keep as many devices off of my private network as possible (less likely to have other devices on it hacked). I know this is possible for wireless devices but I am unable to find how to do this for wired devices anywhere.
Your help would be most appreciated
That's not possible with Nest Wifi. In fact it's not common functionality for most home network equipment.
For seperating wired deviced it's most common to use VLAN tagging, but that's advanced networking and out of scope of what this community is about. 🙂
I'm by no means a network engineer, but it seems to me that by selecting the public Wi-Fi network to connect with, it is setting up a vlan (and the reason I ask the question)...
Strikes me that this work is being done by the point acting as the router, so why does it really matter whether a device is connected to the Wi-Fi or ethernet? The Mac address is presented to the router that decides which network to put the device on...
The only ethernet port on the Nest Wifi does not speak VLAN. If it did, you would have to have a managed switch connected to it that could take multiple VLAN tags to it (aka trunking), then it could put devices on different ports on different untagged subnets.
But this will likely never come to Nest Wifi. For such functionality out of the box, check out products like Ubiquiti UniFi or Cisco Meraki Go for instance.
There are other jank workarounds that kind of could give you what you want, like setting up a inner network inside Nest Wifi, double NAT essensially.
As olavrb said, those advanced security and network management features are not likely to become available natively in the Google and Nest WiFi lines. Your best option for advanced security needs are to look into 3rd party software and hardware options. Still, I'm happy to pass your comments along to our internal teams in the form of a feature request.
