How to recognise wifi with CrowPi2

Hello, I am very happy to be getting started my CrowPi2!:)

However I am having a problem connecting to the internet. No wifi accounts are visible even though there is definitely wifi available and I am connected with another computer.

When I run 'sudo iwlist wlan0 scan' it comes up with no scan results. I have no idea how to fix this. Any advice you could offer me would be much appreciated. Many thanks.

    Welcome to the forum!

    Since you’re just started on your CrowPi2, I would suggest you run the Raspberry Pi Setup Wizard first, it will guide you through the process.

    1. Open a Terminal window
    2. Type sudo piwiz, then press Enter.
    3. Follow the on-screen instructions to complete the setup process.

    Note: For more details on the Raspberry Pi Setup Wizard, see HERE.

    Thank you very much for this!!:)

    I ran piwiz and my wifi network is now visible but I am still unable to connect to the network. In the piwiz it said failed to connect and when I try from the task bar after putting in my password nothing happens. The network is visible in the wpa_supplicant.conf file.

    Before I knew about piwiz, I tried setting up the network through sudo raspi-config so maybe this interfered with something? I also tried many suggestions I found online.

    Is there any way to restore the system to factory settings?

    I don't think I can have done anything too bad because I tried to connect to a different wifi network and was successful. The only places I previously put in my network were in the raspi-config network settings and the wpa_supplicant.conf although I subsequently deleted it from there and retried with piwiz without success.

    Any more suggestions would be very appreciated!

    Your original issue of 'no scan results' was most likely caused by the WiFi country setting. Now that your WiFi network is visible, but 'failed to connect'. There are 2 possible causes that I can think of,

    1. Incorrect password was entered for your WiFi AP. So, try enter the WiFi password on your other device just to verify. 
    2. The Access Control (a.k.a. MAC Address filtering) feature on your WiFi AP/Router is enabled. Login to your WiFi AP/Router admin page to check.

    Is there any way to restore the system to factory settings?

    To reset the WiFi settings, open the wpa_supplicant.conf file and delete everything except the first 3 lines. Then try to connect to your WiFi network from the top menu/task bar.

    Thank you so much for this!!:)

    I don't think it is the password because I have checked this very carefully lots of times but I will try the second option thanks very much!:)

    To reset the WiFi settings, open the wpa_supplicant.conf file and delete everything except the first 3 lines. Then try to connect to your WiFi network from the top menu/task bar.

    I did already try this actually. At first the changes I made wouldn't get saved until I changed update_config=1 to update_config=0 in the wpa_supplicant.conf file.

    I then turned it back to update_config=1 so everything would be exactly the same and tried to connect to the wifi but it still wouldn't connect to wifi.

    Will let you know how (2) goes :)
