The answer to your question depends on a few factors. First, what password is it you are looking for, is it the password to connect to the internet or the wireless password. Second, if it is the wireless password Kenneth is correct. The wireless ID and password can be found on the side of the 2wire or Pace box if they have MTS Ultimate TV equipment. For either of the other options (internet access password or wireless info for Actiontec or Speedstream modem) you would be better off contacting our technical support group as they can help you find and setup this information.
