Thought of everything. Got iPhone. Got iPad. Got charger. Got Airport Express for wireless network. Used it. Loved it. Came back to the hotel room, tried to use iPad, got network error. Rebooted router and tried to reconnect. The fucker had forgotten the password!
Using the iPhone to rant, at the moment. Will try to look for the password somewhere online. Stupid me for using a non-trivial password. Stupid Apple for not including a web interface. And no app to do it from the iPhone as far as I know.
Update: Thank you friends who come over and use their laptops at my place. They can send the network password to my iPhone. 😊
