We TOLD you not to use WPS on your Wi-Fi router! We TOLD you not to knit your own crypto! by Paul Ducklin.
Paul writes a very amusing account of router insecurity that involves crypto tricks that I suspect you can find elsewhere as well.
Like reading critically, security is your responsibility.
If you have the issues Paul describes and you follow his advice you will be less insecure than before you read his post.
Not secure, just less insecure.
PS: Do you know if government offices use Belkin routers? 😉
