Connecting DVR to Internet

I wanted to be able to access Video on Demand, so I ordered a CCK.  I received it yesterday and installed it.  I then tried to follow the instructions on the screen to connect the DVR to the Internet.  I found my network name, but when I was prompted to enter my network key using the DirecTV remote, I began to have problems.  My key has a combination of letters, numbers, and punctuation.  I was instructed to use the number keys on my remote and the dash key for the special characters.  However, when I use the number keys, only the first letter displayed on the number key comes up.  For example, if the first character of my key is "9," when I press the 9 key a "W" comes up (since the 9 key also is used for W, X, Y, and Z).  I also have found that when I use the dash key to enter the "=" in my key, the "=" does not come up when I scroll through the list of special characters.

This is a real problem for me.  I called DirecTV support and it was suggested that I call AT&T and change my network key so that I could enter it using the DirecTV remote.  This does not sound right, as I would have to limit the characters in my network key to the first letters on each key on the remote (A, D, G, J, etc.).  I could not use lowercase letters, the other letters of the alphabet, numbers, or special characters not in the list on the dash key.  That does not sound very secure.  Although my network key is somewhat complex, I haven't bothered to change it because it has a difficult-to-guess combination of characters.  I would think that when I needed to enter a network key, a keyboard would appear on screen so that I can enter my exact network key rather than this limited type of entry that seems to be suggested.

Has anyone else had this problem?  I don't want to have to return the CCK if I can get the DVR connected to the Internet.
