I heard that WiFi signals are not encrypted and can be read. Is there possibility to encrypt signal with software or hardware? I mean if WiFi card could encrypt outgoing signal and decrypt incoming signal it would work? Does that mean router also must do same thing to talk and understand WiFi card?
P.S. I am not talking about protecting access points/hot spots, i am talking about protecting data which travels through Wi-Fi signal against packet sniffing.

There are ways to encrypt the router, go to router and go to wireless security, and look at wireless encryption. Set to to use WPA (preferably WPA2) (do not use WEP unless needed cause it is crackable).

As long as your WiFi router is password protected then the transmission is encrypted. If you did not set a password or had to enter a password to connect to your WiFi then it is not encrypted.
WPA2 is the most secure. WPA is the second best option. And WEP is the least secure.
