Set a default SSID for private wired connections

WMM2 Your simple consumer router does only have -one- network.

One network, the normal wireless SSIDs do connect transparently to the very same network, also accessible b the Ethernet LAN ports. Because of the router does enforce two different SSIDs or network names, Windows 10 does identify these as -two- different networks.    

And then again the very same network, also used by the guest SSIDs connecting (to what extent see above), allowing your guests to access the Internet using the network at least as an intermediate network to access the Internet. Windows 10 does identify these as -two- different networks again.

When looking on the Windows 10 system, each of these four connections will be identified as an individual network. On connecting for the first time, each network is designated as a "public" network (and various firewall rules will be set accordingly) - unless the user does (during the first connection, or manually later) each to become a private network.  

This isn't a feature - it's just the way it is, and how wireless routers are made for a decade or more.

michaelkenwardand antinode I'm happy to put up links to the fine documentation. However, I'm with WMM2 as a user, and here is why:

1. We're in the year 2020, or almost in the year 2021. Even if we talk of a 75 USD router here:

• One would expect from a commodity product maker that correct terms are used. 2.4 GHz is not a network, 5 GHz is not a network,  2.4 GHz guest is not a network, and 5 GHz guest is not a network.
• An SSID must identify the network and the network capabilities - and must not be abused identify a radio adapter.
• The user or the guest should not have to care which band or adapter is to be used to access a certain network or it's allowed network capabilities.
• Enforcing different SSIDs for each radio adapter intended for the normal user access network similar for the guest networks is garbage - even if the consumer router "industry" tried to burn this into the consumers and non-tech mined heads for decades.

2. Guest Network(s)

• Neither the AC1200 Smart WiFi Router - Dual Band Gigabit R6230 Data Sheet nor the AC1200 Smart WiFi Router with External Antennas Model R6230 User Manual does explain the difference between the normal/secure and the guest network. "Guest networks allow visitors at your home to use the Internet." is all we can find.
• Based on experience - not on the documentation - some Netgear routers allow the guest SSID(s) LAN and Internet access, other routers are implementing some L2 filtering only allowing to access the Internet but not the local network or other devices (so denying using or accessing devices on the secure network like a printer, a media player/TV in the guest room, ...). No idea what this R6230 does.
