After having given up on trying to connect to CX's advertised wireless network several times and having had no success, despite enlisting the help of several employees and passengers, I was diligently re-typing a draft of an e-mail I had composed on my laptop into a CX desktop when a lovely CX agent approached me and asked if it wouldn't be easier if I connected my laptop directly to the wireless network, and proceeded to provide me with the WEP key to the access point.

Eureka!

I have asked if the network was encrypted several times before and I have always been told that it was not. I always thought I had the problem but never had the time to look into it. Suffice it to say I am no network guru but I found it strange that the network here was the one of only a few in the world I had a problem with. If anyone needs the key, let me know.
