Even though we come to our offices to work, not a single office worker would lose a chance to use social networks at work when possible. So no wonder why some office managers change wifi passwords from time to time to keep their stuff working, not chatting. However, such a simple thing as a new password can easily turn a simple day into a disaster. And the problem is not the permission to use the internet - it's the new password which is impossible to guess... or isn't it? Try to guess the password yourself and use office wifi for free if you succeed!
