It is a DSL modem/wireless router and I want to secure the wireless connection so others can't piggyback.
OK, that's what I suspected. Are you able to log into the router? Normally this is done from your browser - put http://192.168.1.1 in your address line (I'm assimunign that is the address of the router, although it may also be 192.168.0.1). Once in you will need a username and password XXXXX do you have these or are they the default? Default is usually one of the following:
Username: admin or blank
Password: admin or blank
Once in there may be a setup wizard that will take you through the steps, otherwise you will set up WEP security where you will provide an encryption key - make sure you records that because you will need to enter the same one in your computer. I suggest 128 bit encryption, which will require a 13-character key, like "see spot run." without he quotes.
I couldn't find a setup wizard but I did find the area where I could set up the wireless security. Knowing that it dealt with WEP was the key. Also had to make sure I selected 'shared' connection on both the router and the computer.
Thanks again and Happy New Year,
