Why does Windows 10 see two wi-fi networks on my router?

Question

network hardware

Actually, everything is visible in the picture. I can connect to both networks without entering a password. They differ only in that the second has the number "2" at the end of the name. The smartphone does not see the second network.

Answer 1

The router supports two standards.
The smartphone most likely does not work in 5G, so it only sees 2.4 mhz wifi.

Answer 2

2.4 and 5 GHz?

Answer 3

Disconnect from the internet. Run command line. In it, execute
Code:
netsh wlan show profile
A list of network profiles will be displayed. Remember the network profile that you want to delete and execute in the command line
Code:
netsh wlan delete profile name="Name of the Profile to be deleted"

Answer 4

But what if this happens with the TD-W8950N router, which only works at 2.4 GHz?
