I cant change my password.

I dont know if this is the right place for such a question. If not Im sorry.

So the problem is my neighbours asked for my Wifi password. Eventually I gave the password. I dont want to say ‘’ stop using my wifi ‘’ instead I just want to change the password.

These two devices probably mobile phones are belong to my neighbours. I blocked some mac adresses but somehow people keep using my wifi.

Im not good at ‘’ technology ‘’ So can someone around here help me? It would be really nice.

Go to “Wireless”. Select your wlan interface. Check which Security profile you use. Press again the “Wireless” tab and then press “Security Profiles” tab.
Select the profile you have in wlan interface. Press in left column of tabs the tab “Hide Passwords”
Change the WPA / WPA2 Pre-Shared Key.
Press Apply

This should solve the problem if only you created the key or was it hotspot billing?. Blocking mac will not work cos you never enabled ACL as the security options.
