Constant large download fails

I had a problem one time several months ago. Someone had sent me a couple links to a couple of 5GB folders. I can't remember if they were from Dropbox or box.com or somewhere else. Every time I tried to download either of the entire folders (compressed to a zip file) it would download the full 5GB and then say "lost internet connection". I ended up having to download it in pieces (individual files and subfolders) and that worked. I haven't had an issue since, but I'm not sure if I've downloaded anything that large of late.

Your issue sounds different though as it's cutting out in the middle of the download instead of at the end. I assume you're having issues downloading different files from different locations/servers.

I doubt it's the problem, but the only thing I can think of is that it's a heat issue. Do you have a fan you could try pointing at the gateway? I have the Nokia gateway which some had mentioned had heat problems, so like others, I added a 120mm USB fan to make sure it stays cool. I don't recall anyone mentioning a heat problem with the Arcadyan though.
