Very slow upload speeds

I am experiencing very slow upload speeds (<1.5mbps). I have blast tier service (150mb dl and 10mb ul). It will sometimes take 2-3 minutes to upload a pdf to dropbox. 

 

I have tried speed tests from multiple sites, including Xfinity Speed test, on multiple devices both wired and wireless. All have fine download speeds, but the uploads are as high as 1.7mbps and as low as 0.3mbps. 

 

I have a Motorola 7550 modem/router combo. However, this issue was still present when using a separate modem and router prior to it.
