All of my downloads over ~200MB either fail or end up corrupt

Posted

Whenever I try to download something that's sized ~200 Megabytes or higher, it will take multiple (5-10+) tries to download it with success. The download will either fail somewhere in the middle of the process, or it will "finish" faster than it should, and when I try to open it, it ends up corrupt. I've tried restarting/resetting firefox in the past, but the larger downloads still will almost always fail in some way.

One other issue that is somewhat related to this, is that my internet speed always seems to fall. It's supposedly 6 Mbps, but once it reaches ~500KBps, it slowly drops until it is around 156-180KBps. Sometimes, it will return to the higher speed, but only momentarily. I've had this downloading issue with things other than firefox, such as Steam. I power cycle my router on a regular basis, since the speeds often will reach a ludicrous level, so restarting it hasn't really solved this issue.

P.S. I know the difference between a Megabit (Mb) and a Megabyte (MB) and so forth, so I'm not making any typing errors in the speeds, just in case anyone is wondering.

I don't think a recent update would've caused this download problem, as it's gone on for longer than a month, but I am using version 37.0. I have plenty of hard drive space (1.3 TB), and I'm about to try safe mode.

I cleared my cache and ran it in safe mode, and it worked very well for a while, but my computer crashed in the middle of the download (not related to firefox in any way), so I couldn't download the large file, but atleast I know what was causing the problem.

It is possible that anti-virus software is corrupting downloaded files or is interfering otherwise.

Try to disable the real-time (live) scanning of files in your anti-virus software temporarily to see if that makes downloading work.

See:


Boot the computer in Windows Safe mode with network support (press F8 on the boot screen) as a test to see if that helps.
