I was able to connect to Wi-Fi easily at home. However, when I tried to connect over someone else's house, I chose the name of their Wi-Fi router & put in the correct password for their Wi-Fi & nothing happened. It simply would not connect. I tried updating & upgrading the Pi 3 but that did not help. Thank you for your help

  • Unless you tell us about the network we can't help. sudo iwlist wlan0 scan is good advice to find this. Many people still use WEP and this can't be configured by the GUI tool.

My first attempt would be to list all available hotspots. This can be done via

sudo iwlist wlan0 scan

When you can see the hotspot you want to connect check if the provider uses DHCP or static IP addresses and if it matches your configuration.

The last thing I can think of would be the usage of hidden SSIDs. Then you have to include 2 settings.

Just to check - here is the configuration that I use:

auto wlan0
allow-hotplug wlan0
iface wlan0 inet dhcp
wpa-ap-scan 1
wpa-scan-ssid 1
wpa-ssid "name of hotspot"
wpa-psk "password"

One more thing: if the authentication is not WPA or WPA2 you have to specify it as well. I think this case is rather obscure. You can see the authentication in the result of the scan.

  • The "configuration that I use" may work for you (by good luck) BUT is poor practice and not robust. You can continue to use dhcp if you wish but others should follow the recommended Foundation practice.

  • This is what I got when I check for hot spots.
