1. Absolutely sure about the password. Have sat with him and entered it.
2. Yes, have double checked the encryption type against the encryption type for my other two computers. Just to be super safe, I have tried every permutation of security types and encryption keys.
3. I can double check on Mac filtering, but it has never been a problem before.
On occasion in the past, this computer has had difficulty connecting for no apparent reason, though it was intermittent and usually after I had brought it elsewhere and used a different network (though not always). When that happened, I would have to go to Network and Sharing Center and do a diagnostic, usually resulting in a new IP address needing to be randomly assigned. The diagram would show my computer connected to the router and the a red X between the router and the internet.
Now when I go to Network and Sharing Center, the diagram does not show the router, only my computer, a red X and the internet. A diagnostic fails and tells me that a security key is incorrect. The adapter says it is awaiting authorization.
