Recent versions of Windows (7 and newer, i think) seem to be able to identify the network, that they are connected to via Ethernet automatically.
The name "tbspace Networks" is the WiFi-SSID of the CPE this machine is connected to. But this machine is connected via Ethernet, not via WiFi.
When connecting to a network with a custom DHCP/DNS server this does still work, also configuring a static IPv4/IPv6 address still doesn't change the autodetection.
How does Windows identify the network name?
Can I propagate my own network name with a Linux host?
you should probalby start here with a description of Network Locations. http://www.digitalcitizen.life/network-locations-explained . It is likely that it was discovered by SSDP or Homegroup features. you can confirm this by turning the network type to Public and rebooting. SSDP and homegroup functions are disabled on Public networks by default.

How does Homegroup work network-wise? Isn't that handled via SMB? I couldn't see any such traffic -- altough it could be encrypted. – Tobias Mädel – 2017-04-28T14:54:46.940
With a sniffer you can see Text data, but many network services use binary data layouts. while it is possible to sniff them, it will take a protocol intelligent decoder to make sense of the content. – Frank Thomas – 2017-04-28T15:09:28.030
1Try this: Find in the registry key
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkList\Profiles
, among the subkeys identify the Ethernet adapter by the item namedProfileName
and change the name, you might also changeDescription
. Note carefully the old values, or better - export the entire subkey as backup. Reboot might be required. I don't have wifi so cannot test this. – harrymc – 2017-04-28T16:25:43.503Have you connected to that network before through Wi-Fi?. Not really sure of the following, but maybe Windows cached the SSID and is displaying it now for the Ethernet connection as they both share the same gateway address or MAC?. – Jaime Hablutzel – 2019-04-28T14:31:36.953
@Jaime Hablutzel: No, the PC has no wifi card. – Tobias Mädel – 2019-04-29T06:01:25.757
