Please do the following:
- You can reconfigure the Wi-Fi connection if you switch back the openSPOT2 to access point mode by pressing the button for 3 seconds.
- Make sure you've entered the Wi-Fi password case sensitive.
- Place the openSPOT2 close to the Wi-Fi router.
- If you have WEP encryption on your router, then make sure the password is ASCII, not hex. The openSPOT2 only supports ASCII WEP passwords. The best is to switch the encryption to WPA2 or WPA because it's much safer.
- Make sure you have enabled 2.4GHz Wi-Fi, not just 5GHz.
- If it still does not work, try switching Wi-Fi channel on your Wi-Fi router. Only channels 1, 6 or 11 should be used (see explanation here:
