I have two WLAN SSIDs. One is operating at 2.4GHz frequency, and the SSID is "stratus24". Other is operating at 5GHz frequency, and the SSID is "stratus50". Both of these WLANs are bridged to the same Ethernet LAN. So, there are three ways to access the same network: via "stratus24" SSID at 2.4GHz, via "stratus50" SSID at 5GHz and via an Ethernet cable.
Now, if I connect my laptop (that has been previously connected to both stratus24 and stratus50 WLANs) via an Ethernet cable to the LAN, Windows 10 decides that the name of the wired network is "stratus24".
How does Windows 10 decide that the network is "stratus24"? Is it using the MAC address of the default router? Or the MAC address of the DHCP server? Both the DHCP server and the default router happen to be one and the same device, but that may not always be true.
