When trying to connect my MiFi 5510L , I keep receiving the following error message "Windows is unable to connect to the selected network. The network may no longer be in range. Please refresh the list of available networks, and try to connect again". My computer does recognize the wireless network.
You are most likely entering an incorrect password when attempting to connect to your MiFi. Try wiping out the password that is saved on your computer for the MiFi and try again. If you are uncertain what the WiFi password is then reset your MiFi by pressing the pinhole sized reset button underneath the back cover. After a reset is performed you can use the default connection credentials on the back of the device.
