I use both OneDrive and Citrix Files to backup various documents. My broadband/wifi is normally pretty stable; however, when either of these programs start to upload files to the cloud, my connection drops out pretty much immediately. This usually impacts all devices connected to the WiFi, not just the device doing the uploading. Usually when this happens, the WiFi remains connected, but I get a "no internet" error. As soon as I turn off the cloud synching for these programs, the internet connection becomes stable again.
