Dropbox could well be involved, depending on what you have stored there. Just as an example, Dropbox has the annoying habit of asking you if you want to store your photos there, every time you attach a mobile device or an SD card. A friend of mine brought her work’s network to its knees after unwittingly agreeing to this, at which point Dropbox commenced syncing over 1200 photos to its servers. The activity saturated their little wireless router, rendering the network virtually unusable while her computer was on. I’m not saying this is necessarily the problem in your case, but it would be instructive to have a look at just what you have in your Dropbox folder. Dropbox is certainly a safe, reliable service, but like everything it does need a little care and attention. I make sure I only use it for smallish files. The really important stuff I keep at home.
