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). Didn't they crack WPA2 also not to long ago? And what about signal that travels through Wi-Fi? Can't it be sniffed? 2
WPA2 has not been cracked. Only WPA-TKIP was recently cracked. The data can be sniffed, but cannot be decoded without the correct encryption password Hmm them I must have mixed it up. But sooner or later they will crack it also. Hopefully they will have come up with something even more secure by then. Guys but what about public routers for example in hotels on pay-per-hour basis for password? I am talking if 5 people will pay for password to access router and connect to internet. What if one of them is a sniffer? There is still risk in public router even with encryption that my data can be stolen by people who paid for internet. Get a free VPN, encrypt all packets with it There are some providers that have a free VPN option, or you can pay for one. @Boris_yo, if they are using WPA2 you are safe, other wise get a good VPN to save your shuttled data.

WPA2 encrypts all data streams to and from the router to the node. :-) So, you're protecting the hotspot from people getting on it to try to snoop in the first place, and you are stopping those that are already on the network from snooping your packets. WPA2 stops Firesheep in its tracks!
