WiFi made life perfect. No wires and Internet every where in the house, but you have to keep it safe. i know a lot about security and i am trying to work in this field. a few days ago i was just war driving in my apartment (shouldn't be called war driving as its not in a car, but its the same thing :) ) and i found unprotected WiFi network and i was like... mhmmmmmmm maybe he got his router set to not accepting new connections. so i tried to connect and it surprised me i connected with no problem.. and i was able to find his phone number and everything that his ADSL provider has. i emailed him and told him about it and how he should protect his WiFi network.
if you are using Ubuntu or any linux os i think you might already know about security and how to keep your WiFi safe, but i will talk about the basics of how to keep your WiFi safe.
there are different types of protections which is WEP, WPA, and WPA2 and WEP is the weakest and WPA2 is the best. however they are all crackable and if someone have the knowledge and softwares, he will be able to crack the network and find out your password. WEP the the easiest to crack so you shouldn't use it and i recommend WPA2. most routers will have a default password.. CHANGE it to something else. Use longer passwords and write it down on a paper. DO NOT use common passwords like Admin, Password, 1234 ..... you get the idea.
over all if you want a safe WiFi there is a lot to do and you router have a lot to set to keep it more secure, but don't play with anything if you are not sure. if you want a protected Internet connection, use wires :)
