Wanted to ask possible to crack it ? How much effort does it take? Maybe quick info on how to do it would be useful.

Quite a lot of work to put it off, you probably want to use Aircrack, if you want to attack for the outside, this article might useful. It would be much easy to social engineering you way into the target (Hello I work for {insert ISP name}, we are running critical tests on the system, should only need a minute with your router to reset everything) and then coping to WiFi password from the router as most people don't change the default router password, even if they did change it, just copy the admin password and the IP address to router control panel or reset the router with a pin.
