It could be a site issue or something like a security suite stepping in the way.
I've seen such with security suites as they expire.
Recently my computer stopped downloading anything that wasn’t a really small file. Once it gets close to the end, it pauses, and fails. If I restart my machine, I have three minutes (or so) to download something normally before the problem starts again. This happens across all browsers. Other computers in the house seem to be downloading things fine.
I’ve tried restoring my machine, but it’s still happening. I have to download things like updates and firmware on a different computer in the house. I tried downloading the latest firmware for the Ethernet Connector, but it’s still happening.
Does anyone have any suggestions?
