Untag VLAN
Looking for some guidance on "untag VLAN" as suggested by Google. I have an ISP router from Movistar with a Fiber Optic connection and they have suggested I do not use Bridge mode on their router...

Ok - the reason for the untag VLAN was a google solution. I have a Movistar fibre optic router with a 1gb connection. The house is pretty big. I liked the idea of Google Mesh network with points that act like Alexa. So I got two google Home Nest mesh routers and three points. However the performance ,checking with speedtest is not great. Google support suggested Bridge Mode for the router but Movistar say that is not a good move as their router only acts in like half bridge mode and still uses VLAN's . So Google suggested getting a managed switch, which is where Netgear come in, to untag the VLAN and installing it between the Movistar router and the Google Nest router. So is the untagging useful and will it give better performance on the network. I should also say their is no fixed telephone requirement nor any Movistar TV. There are Android based IPTV boxes and a couple of Macs and phones. These devices are spread around the house and basement.

Strongly doubt they have an idea what is going on in front (WAN: Internet, Phone, Movistar TV) and then on the LAN side of these routers.

So only one Google Mesh Router direct connected by Gigabit Ethernet, while everything else is supposed to be magically wireless or mesh. And everything in a bigger house. Must be fun. Reads good from the marketing prospective, however I have my doubts.

The only point you will get good performance are the LAN port(s) on the Movistar CPE. Run your speed test on that LAN port using e.g. a PC or a MAC with an Ethernet adapter connected.

So these Google supporters seriously think there re tagged frames on what makes up your home LAN serving Internet - but you don't have to configure anything on the connecting computers (Mac or PC)? The answer is: There is no VLAN tagging for what makes up the Internet access. What is coming in on the fiber for the Internet data on VLAN 6 is made available conveniently in IPv4 NAT and a IPv6 net for all your Internet access devices.
Anything that is flowing over this magic Mesh, a little bit faster between the Nest router and the second Nest router configured as a point will flow over a AC 4x4 2200 connection. Anything that is flowing to the Nest Points and your wireless clients will go twice over a AC 2x2 1200 WiFi mesh link. In case there are walls, multiple walls, the performance will be reduced massively. You seriously expect performance near to the Gigabit Ethernet link speed? Keep on dreaming.

So you believe think there are tagged frames for the Internet part on your LAN? The config you are behind is this: Configure an trunk port for VLAN 6 Tagged, and no other VLAN memberships to connect one of the Movistar LAN port, and one access port on the switch to VLAN 6, untagged, PVID 6. to connect one of your test Mac or PC, and later to connect the Nest router WAN/Internet port. I would bet there won't be any Internet traffic available. Yalla yalla.

More dreaming. Any tech references on such a config please? Granted, you can forget about the two VLAN 2 IPTV for the Movistar TV and the VLAN 3 for VOIP if these paid Movistar services are note used.
