Those people run for example wireless routers at factory defaults because they don´t know better, they think the device is safe the way it´s preconfigured.

My personal advice would be to avoid using something that you don´t know enough about. You should read at least the instructions which should help you setup a relative secure system but that´s of course not sufficient. You should do some research on the internet and articles like the one mentioned above help you understand the concepts and secure your wireless connection.

You could hope of course that nothing will go bad, that no one will get access to your computer, find out about your private files, share child pornography with it, download music from it aso. But I would not take any chances.

Back to the article: It lists Vulnerabilities and Attack Methods (Human Error, Rogue Access Points, Warchalking, MAC Address Spoofing, Noisy Neighbors, Improper Design and Man-In-The-Middle Attacks). You get a good basic understanding of those vulnerabilities and attack methods. This is of course no in depth knowledge but solid beginners knowledge. As always, if you want to know more you have to research.

After explaining the attack methods the article lists defense measures starting with basic defense methods. (WEP, MAC Address Blocking, Ditch the Defaults, Beacon Intervals, Access Lists, Controlling Reset and Disable DHCP)

The article gives a basic overview, you will have to find out how to setup your wireless router properly, that´s something the article won´t mention. Mainly because there are hundreds of different routers out there and it would be impossible to give configuration advices for all of them. Read the manual of your router and I suggest you visit the manufacturer homepage and see if there are updates for it available (firmware for instance). Maybe the manufacturer has a forum where users post their experience, this are always valuable sources for information.
