I have no idea if it involves connectivity. I do know I have gotten disconnected while doing some things, I'll try and recall when but first, I have a dial-up modem. NO DSL.
Now, I have gotten the AOL ERRORs (AC - 3000); (AC - 1502); (AC - 1200). When I first had the computer reformatted, I got the disconnects a few times, reported it to AOL and they advised that perhaps the reformat wasn't proper, so it was re reformatted. But I still got a few disconnects so I switched Access Numbers. Whereupon, I still got disconnected a couple of times. I know I got disconnected twice(in the same session) when I was using the IM, it took me to the BIOS pages; and when I had more than two windows open.
I have been dealing with so many connection and disconnetion lately it's hard to keep them straight.
I haven't heard anyone mention what microsoft suggested might be the problem, so I'll keep waiting rather than make the suggest myself.
