Have 2 laptops connected to wireless router

Try to go to start -> settings -> network connections -> and see if your connection is working properly if there is a problem it will say it's limited. If limited try right click and repair, if it won't work try right click on connection then properties and in ip/dns section set all on automatic. 

If none of this will work try to disable firewall for few min and see if it works, to do so go to control panel Windows Firewall,

If password would be wrong you wouldn't be able to connect at all, you can always try to go to available wireless networks and try to disconnect your connection and then reconnect again it should prompt for pass.
