iPad Wireless Connection Issue

I received my iPad which I ordered two weeks ago. It seems that I may be one of those small number of iPad users who are experience wireless connection issues. The wireless signal fluctuated from strong to weak, while my other laptops and iPhone showed a consistent signal at the same location. In addition, I was asked to re-type the password in order to connect to the wireless network from time to time. I found the Apple knowledge note and changed my WiFi router setting to use WPA/WPA2 security. Hopefully the rest of the connection issue can be addressed in the upcoming iOS release.
