I have found this possible solution, it worked for me!
Sorry for my english!!
I was having the same issue.
Below is something that I found on the internet which helped me out




It turns out that Windows 8.1 doesn't show ad-hoc networks and it's by design, and the hotspot created by Joikuspot is an ad-hoc network.

There is a way to manually connect to that network, however. Note, this is NOT about how to create an ad-hoc network to share your Internet connection with another device! It's about how to connect your Windows 8.1 PC to an existing ad-hoc network created on another device.

How to connect to an ad-hoc WiFi network in Windows 8.1.

Because the wireless network picker in Windows 8.1 doesn't show ad-hoc networks, connecting must be done by hand.

To see all networks in range, including ad-hoc, run this command in command shell (cmd.exe):
> netsh wlan show networks

SETUP

This must be done only once per network.
• go to "Network and Sharing Center"
• click "Set up a new connection or network"
• double click "Manually connect to a wireless network"
• enter the SSID of the ad-hoc network (as shown by "netsh wlan show networks") into the "Network name" field
• configure security settings accordingly
• uncheck "Start this connection automatically" (important)
• click "Next", then "Close"

Run this command (important):
> netsh wlan set profileparameter <ssid> connectiontype=ibss

Replace <ssid> with the SSID of your network.

CONNECT

After setting up, run this command whenever you want to connect:
> netsh wlan connect <ssid>

Replace <ssid> with the SSID of your network.

Hovering over WiFi icon in system tray will show the name of the network that you are currently connected to, even if it's an ad-hoc network (the network picker will not show it if it's ad-hoc). The name is also visible in "Network and Sharing Center" window.

DISCONNECT

To disconnect from the ad-hoc network: connect to a different network, turn off wifi, or run this command:
> netsh wlan disconnect

CLEANUP

To remove the network profile from Windows, run this command:
> netsh wlan delete profile <ssid>

Replace <ssid> with the SSID of your network.
