My wifi stop working suddenly on my CTT V3 trying to locate my wifi name stored on CTT. Does any one know raspberry pi command to retrieve wifi name. I have seen it done in past but forgot how. Lots of suggestion on web none work. Wifi transmitter does work. Of course receiver is out side in cold and hard to type on computer with -3 C wind chill.
Hi Glenn, you should be able to locate / edit the current WiFi settings by opening the wpa_supplicant.conf file. The command for doing that in its default location is below.
sudo nano /etc/wpa_supplicant/wpa_supplicant.conf
Though given the location and the temperature it may be easiest for you to overwrite the current configuration with credentials you know are working. If you have a V3 SS you can do this with a USB drive. There are some instructions on the SS manual here: Installation Guide for the CTT SensorStation and CTT Nodes
Not sure if this will be exactly of use, but:
sudo iwlist wlan0 scan
will show you all of the wifi networks detected in range
