When I try to download large files, they always stop part way through. It seems like I can't download anything that takes longer than 30 seconds to download. There's no error message - it just appears that it's trying to continue to download but nothing is getting transferred. The other day, I used someone else's network and I was able to download fine. That seems to point to an issue with my network. However, the PCs on my network don't have this downloading issue. Any ideas?
