Connecting the iPad to a Wi-Fi

I have an iPad and have successfully connected to two other networks but can NOT connect to my network at home. I am using a Belkin F5D8053, 802.11g, n router with WPA personal. The iPad sees the network but when I enter the security password it says the password is invalid. I’ve quadruple checked it and tried numerous times over two days. I’ve had others watch me enter the password and also had them enter the password, always with the same resulting invalid password message.
I even deleted the connection from my laptop and reinstalled it successfully with no problems just to make sure I was using the correct password.
