changing passwords
 

How do I change the passwrds that allows you to use my wifi. I am computer stupid and cant figure it out, I even used google to try and do it and didnt quite understand the instructions. PLEASE HELP! THANKS

Assuming you're talking about the password for your router/hub/ that comes from your ISP and I don't think you can change it. When you signed up for your WIFI service you should have received documentation telling you (among other things) what your password is. My ISP is BT (British Telecom) and the password appears on a plastic card located in a slot behind the hub.

I assume you are not talking about your own password or the administrative (root) password for your machine. You'll have to be a bit clearer if you expect to get any assistance.

Can you describe your WiFi router or upload a photo of it?
