It could still be genuinely anything. I know AT&T is still having some serious outtages in some areas, and after calling up my ISP, they too were having node issues due to either high volume traffic or just general need of maintenance, at least that's the generic response I got.
When I made this thread, I wasn't exactly sure of the cause other than it was causing me to have constant disconnections, and was just trying to make sure it wasn't just me and my router.
