My router has a hidden broadcast. Let's say it's called Eagle. I've set my Vista Enterprise SP1 to detect it.
But after a while, something strange started to happen: on the list of available networks, I started seeing and Eagle, Eagle 1, Eagle 1 2, Eagle 1 2 3, ...
Today, I'm all the way up to 15.
And sometimes, there's an "unidentified network" on the list. If I choose to connect to that, enter the name "Eagle" and enter the correct passphrase, I have a succesfull connection.
Does anybody here have experience with that kind of thing?
