Change authentication wifi WPA to WEPon Windows 8

Question

I use

netsh wlan set hostednetwork mode=allow ssid=Kites key=phambaoViet

netsh wlan start hostednetwork

To share WiFi from LAN network on laptop (Windows 8) to my other device.

When I show information netsh wlan show hostednetwork the supported authentication is WPA.

My device support authentication WEP only.

How can I change the authentication to WEP?

Answer 1

WEP encryption on hostednetwork is not possible. It will run only with WPA. But you can search for third party software which may provide this feature.
