In some cases, it helps to delete a wireless profile and create a new connection from scratch.
In Windows 8, this is normally done by right clicking on the network and selecting “Forget this network.”
If this option is not available, a command line terminal can be used to run the following commands.
To open a command line, right click on the Start menu and select “Command Prompt”
In the command prompt, type netsh wlan delete profile name=”miis”
Now you can start over with connecting to the miis wireless network.
