I notice I was having the problem of no connection on one of my laptops even though it asked for the key to connect, it would not connect with my3GS using MyWi. I found it may not necessarily be MyWi's fault because my Macbook Pro would connect while my older Powerbook would not even though it accepted the WEP security key. When I took off the key both laptops worked. Perhaps someone can explain, but again, you might consider removing the key if you are having problems just to see if that is the cause of your problem.
