KInternet problems

First, thanks to all who offered assistance with my logout hell problem! I now have things configured correctly.and log out works as it should. Now for the question/s du jour: How can I get KInternet to stop disconnecting my modem about every five to ten minutes? Also, I've read that wvdial is a better program. YAST shows that I have wvdial installed but I can't find it. It isn't listed under Internet> dial up on my main menu as KInternet is. Where should I look for this program (wvdial)? Any other suggestions are, of course, most welcome. TIA. LTR
