Every time I try to download files from my browser, it doesn't work. For smaller files, the progress bar gets about halfway before it says the download was unsuccessful, and for larger files the progress bar just jumps to 100% and days the download was completed, but the file is an unknown format or is corrupt (observed mostly with zip and rar files). I've looked around but haven't come up with a solution or even a reason why this is happening. Help would be appreciated.
