The AT&T network is simply rigged so that users cannot download large files directly. We tested this multiple times, and it is 100% reproducible. But then, if I stop the browser-based download, within minutes my broadband WAN connection speed goes right back up to ~18Mbps. At one point, my broadband connection actually went down (the broadband light on the modem went red and I got an error showing 'Broadband connection not available'). If I tried to visit other sites, the connection was terrible. The download would suddenly become impossible (appearing to require 10+ hours to complete). Within a minute of initiating the download, my overall broadband WAN connection speed would throttle down to <1Mbps. Then, I would attempt to download a large file from. I could visit sites, watch videos, run, etc. The speeds were fine, in-line with the plan I have. How did we deduce this? David created a new network SSID on my router and had me only connect one device to it (so that no other devices would interfere with the test).

Here's what we finally deduced: Attempting to download a large (2GB) file via a web browser from results in my broadband WAN internet connection being throttled down to less than 1Mbps (with an effective download rate of <200Kbps.) A few minutes after the download is cancelled, the broadband WAN speed goes back up to normal. I spent about an hour tonight troubleshooting an issue with AT&T technician David who works via phone from Wisconsin. Two basic methods can help you overcome the problem.I have a Pace 5268AC router connected via the 18Mbps plan. To solve the issue, you need to erase the system cache file. Many times the error occurs due to the system cache file. Method 3: Clear the System Cache FileĪ lot of reasons can be behind your Dropbox Error 500. If not, head over to the following potential method to solve the problem. Open your Dropbox Cloud Storage and check whether the issue is resolved or not.

One of the common mistakes that people make while surfing over the internet is they do not clear cache and keep on changing from one website to another.
