Hello,

I have Airtel 4G modem (hotspot) on my laptop. I don't know to set the password for it. I am afraid that others might use it without my knowledge.

Please tell me how to set the password for my WiFi.

I'm having problems with my Wi-Fi on my laptop. All the blue lights on the top indicates that it is on, but there is an orange light by the picture antenna that turns it on and off. It stays orange and when I need to get on line I can't. My wife's laptop is doing the same thing and we would like to know why this is happening. Is it a Compaq problem? When we first bought the laptops they worked.
