Airport won't connect--"no dial tone"
I use airport with dialup. My windows laptop can connect, but my airport can't connect "no dial tone" but i checked this line with an adjacent phone and i'm using this line now (for work i use this line without airport to access my work server but must use windows) I reset, reconfigured, check the line and nothing has helped, Is there a way to turn the airport modem sound on so i can tell, or is there something bad going on inside.what should i check next, any diagnositcs
