Frequent disconnects on AIM

I have a problem with disconnecting a lot on AIM. Every now and then (about every hour/half hour-ish?) AIM will randomly disconnect and reconnect. I thought it was my ISP (Comcast), but almost all of my friends use Comcast and no one else has the same problem. The weird thing is that, when I switched to GAIM temporarily, it worked fine. But I don't want to use GAIM for various reasons (mainly because I can't directly connect to anyone on it which is something I do frequently).

tl;dr How do I not disconnected on AIM?

I've seen many quicker. At the height of the Blaster situation (and for months afterwards), you could barely get a cleaned machine back onto the internet to install the patch before it fell over again. I tried the same last month with my old computer (just for kicks), and it was crawling inside of 10.
