I recently posted instructions for connecting your iPad to your home network by turning off Wi-Fi security and disabling SSID broadcasting. That will do the trick for your home network, but if you're traveling with your iPad you're still going to run into LOTS of problems.

I'm sitting right now in the Washington Dulles airport lounge, trying to connect my iPad to my Sprint Overdrive Wi-Fi router/access point. My Macbook Pro connects just fine using both WEP and WPA security profiles. My iPhone 3GS connects just fine.

My iPad however will NOT connect to my Sprint Overdrive using any of the wireless security types. Not WEP, not WPA2, none of them. It won't even connect with security turned off!

Apple recently published a 4.0 update for the iPhone, but it's definitely time for an iPad update.

They know this technology too - they've proven that with Macbooks and iPhones. They just need to port that knowledge over to the ipads. And soon.
