iPad constantly drops my wifi connection...

My iPad constantly disconnects me from my wifi in my home. I have a windows-based computer that NEVER drops the connection. After several conflicting answers, an Apple support person told me that I need to change my network settings (frok WEP to something else). Not beimg a techie, I called Verizon about it. Verizon told me that I should not do that, because it is obvious that the iPad is the only device on the wifi network that cannot hold the connection and that by changing the settings, I will potentially be opening up a whole new slew of problems. Also, changing the network settings will require me to change the settings on EVERY device I have in my home...something I have never had to do, evevn with Windows-based computers.

What is the real story here?
