I cannot download large files (over 15mb). Not in Firefox or IE. I also cannot upload anything more then a small mp3 file via FTP to my server.
This problem happens on my laptop and my desktop (both have the same os).
The issue happens on wireless or wired connection at home.
Ive tried safemode+networking+wired and the issue happens.
AV and firewall disabled, the problem still happens.
I get a "c:blahbklah_filename.mp3 could not be saved, because the source file could not be read." error from firefox whenever the error occurs.
Ive tested to see if this was caused by my router, so i connected to a different wireless network, and the same problem existed.
