|When did you get the message, that ehe passkey is incorrect, when trying to connect to your router wirelessly?|
I guess you do.
Have you changed the SSID from the factory settings to your own network name?
Otherwise, there might be another router in your environment, that uses the same SSID (Service Set Identifier, wireless network name), so that you might connect to the wrong wireless network.
