CNN Notices that WiFi is Insecure

josh3736 writes "From CNN comes an article that makes painstakingly obvious to the public what we already knew: 802.11 security is horrible. The article points out that nearly 40% of wireless network APs haven't even been changed from defaults and as many as 80% of home APs have encryption disabled. The article goes on to say that '[t]o make matters worse, users who don't secure their networks are often the very people who don't keep their computers up to date with the latest security patches and antivirus software.' It also accuses WiFi manufacturers of disabling security measures by default to make wireless easy to the lowest common denominator. My favorite quote? 'Experts say that while Wi-Fi hardware makers have made initial setup easy, the enabling of security is anything but. Meanwhile, average users are no longer tech savvy.' Which is to say that they at one point were?"

    Personally, I would love to see some more options when it comes to turning WEP on. Since my laptop connects in both a wired and wireless manner to my network, it would be great is some software generated a new WEP key to use each time I went wired. I see no reason that the end user would need to be involved, any weakess on the part of the pseudo-random generation of a new WEP key would be less insecure than having the same one for months on end.
