About a week ago I began experiencing problems with every sufficiently large download. Web pages and e-mails worked fine, but any download in excess of about 1MB would fail somewhere between 1MB and roughly 5MB. By any download I include:
download of zip files etc. from www
viewing of quicktime files online, e.g. apple trailers e.g. ultivillage.com
download of any file through irc
download of songs through iTunes
ironically, download of a new version of ZoneAlarm, which I had to restart 5 times to complete
I can still download larger files with bittorrent and can stream audio into RealPlayer.
After some days of fiddling with hardware, I discovered that if I simply shut down ZA then all downloads work fine. I checked my settings and they looked fine. I upgraded ZA and had the same problems. I installed ZA Pro and had the same problems. To preclude some suggestions I should note that my DHCP server (router) and DNS servers are all in the Trusted Zone and all privacy controls are off. I see no logged events concurrent with my download problems. But if I have to turn off ZA to use the internet, something is wrong.
Does anyone have an idea what could be causing this behavior and how I can fix it?
