For the past two days or so, whenever I try to download a file over about 30 MB, no matter what web browser I use, the download will start, and then stop at a random amount of MB's downloaded. I've had it stop anywhere between 3.2 and 33.6 MB. For a while, it seemed like each time I tried to download the same file, it would download less and less every time I tried it. But now it seems to be stopping in random places. This happens on both my iBook and eMac. FWIW, It just occurred to me I did just enable file sharing on both of them recently, so I wouldn't have to use a flash drive all the time. It seems unlikely to me, but could this be the problem? Thanks in advance for the help.
