How to view all WiFi networks around me

Question

How can I view all the available wifi networks around me?

Answer 1

At top right corner of your system you can see a signal symbol. Click on that and tick the Enable Wi-Fi.It will show all available Wi-Fi networks.

Answer 2

I've seen many occasions where, for some reason, NetworkManager's GUI doesn't show all the available networks. In fact at times it doesn't even list Wireless as a choice. On those occasions I use the cli option to scan:

$ nmcli -f in-use,ssid,bssid,signal,bars  dev wifi

*  SSID               BSSID              SIGNAL  BARS 
   Apollo III (TWC)   xx:xx:xx:xx:xx:xx  100     ▂▄▆█ 
   Chromecast8481     xx:xx:xx:xx:xx:xx  100     ▂▄▆█ 
   TWCWiFi-Passpoint  xx:xx:xx:xx:xx:xx  90      ▂▄▆█ 
   Apollo III (1)     xx:xx:xx:xx:xx:xx  90      ▂▄▆█ 
   CableWiFi          xx:xx:xx:xx:xx:xx  87      ▂▄▆█ 
   TWCWiFi            xx:xx:xx:xx:xx:xx  87      ▂▄▆█ 
*  Apollo III (1)     xx:xx:xx:xx:xx:xx  70      ▂▄▆_ 
   ZJG8Q              xx:xx:xx:xx:xx:xx  47      ▂▄__ 

For security reason I X'ed out the mac addresses.

If I have connected to the network before I can use this cli to connect again:

$ nmcli c up "Apollo III (1)"

If I'm connecting for the first time I'll use this command:

$ nmcli d wifi connect "Apollo III (1)"

A GUI prompt will come up with the option to type in the code works the terminal screen will respond with successful activation and I'll be connected.

I also tested to verified that the elevated sudo command isn't required for any of the commands above.
