Chances are..if your phone lines are DSL compatible (which they are seeing how you are using AOHell DSL)..there are other alternatives. Either thru your local phone company, or another 3rd party (such as earthlink/mindspring, which i have used with 0 problems for the past 5 years).
Also..keep in mind that even if the HARDWARE of the systems are identicle...they arent the same. Different software has been installed on each system, and in different orders etc. THAT makes the difference. I wouldnt go blaming sony, id still go blameing AOL for releasing un-tested software as they normally do. The way AOL loves to think is that you have a computer that runs their software ALONE, and as the brain center of everything....which..in most cases..isnt true.
You think THIS is bad, try removing AOL from your system completly...
