Normally a computer's location [LAN Local Area Network] has only one Wireless Router and it may be combined with a Modem device provided by the user's ISP subscription for connecting to the Internet. Desktop computers may have a Wireless/Wi-Fi adapter and an Ethernet port for a wired connection to the Router, many Notebooks will also have both. My latest inexpensive Notebook is Wireless/Wi-Fi only, if I need Ethernet connection to the Router I will use a USB Dongle/adapter with the RJ45/Ethernet port on it. A number of Wireless connections may show on a computer but probably will be neighbors' and will be Locked, require a password. I have 16 visible in my area not counting mine and all are locked.
