By rights, just moving the router should not have changed any settings, so it is hard to guess what may have happened. Based on your post, I am guessing that you are not entirely comfortable going in through the router's web page? It may just be easier to re-set this up at this point.
I am going to recommend the easy way to re-set up your router.
1. Reset your router to factory specs by pressing the red reset button in the back for approx 5 seconds.
2. If you have not done so, install Cisco Easy Connect (if you do not have the disk, download it here, make sure you show the right router version) -
3. Set up your router, name or re-name your SSID (easy connect will give it a name, but that is easy to change).
4. Again, sticking with the "easy" theme, take a flash drive and use easy connect to create a key to set up your additional computers/laptops.
There are other ways to go about this, but I am guessing that you have a pretty basic set up (no offense meant by that!), and this will work and should be relatively goof proof.
PS. The button on top of the router is the WPS button...just pushing it will not automatically re-connect everything...frankly, I never boither with WPS.
I hope that this helps.--
