I tried several programs that were supposed to help but nothing worked until I changed ISP's. On AOL I got bumped almost every 10 minutes and it sometimes took hours to get back on just to be booted again. Now with my new ISP I have only lost my connection twice in over a year and it only took a second to reconnect!
windsurfer... I used one of those 'ping' programs several years ago when I had AOL and a dial-up modem. It was made for the Mac, so it's not among those in your link. I don't remember the name, but it worked quite well.
For all AOL users, they now have a program that you can install that will stop you from getting bumped. All you have to do is call them, tell them the problem and they will send you a disc, or you can download it from the web site at least that's what they told me when I cancled my service with them.
