Dropbox web keeps dropping uploads after a few minutes saying I have no internet

Ok...so I decided to go another route and break up my files into a few zips so my ISP won't complain about size...but as I was doing that, I saw a pop up from drop box saying upload is complete with a share link available.
However, the same error messages are still displayed saying the upload is currently paused.
So something is buggy about all of this.
I'm using the latest FireFox version but also because as I was searching I saw someone say to try using the desktop app.
So I did and I don't see the point in that since all it does is add a few options when right clicking a file - In the end, still using the browser to upload anyway.

Since I haven't seen a resolution in this discussion, I'll post and say I have the same problem with synching from a Windows 10 machine (not a Mac!) on both the desktop app and through the website via the browser (I've tried Chrome, Firefox, and Opera). I've had problems with files of all sizes--nothing bigger than a couple hundred MB--but currently, I'm running into the "Uploads paused" brown banner with a message near the filename "Paused - no internet" for 469K or 1015K PDFs!

I don't have any VPNs or firewalls that traffic is going through at home. We had to switch to cable internet (Xfinity Comcast) which shouldn't be restricting traffic to Dropbox domains. It has slower upload speeds, but testing shows it's typically ~20-30 Mbits/sec so a megabyte-sized file should not be an issue.

In these situations when the upload has "paused", I'll cancel and retry. Sometimes I'll walk away from the computer and eventually the file gets synch'ed up perhaps hours later. But it's pretty frustrating to see that 20% of a 1 MB file has uploaded after 1 min, but then the browser is stuck on the rest of the minuscule file before Dropbox gives up with the brown banner of death:

I regularly upload gigabyte-sized videos to YouTube without an issue with my current network configuration. Is there something fundamentally wrong with how Dropbox is talking to its servers from my computer?

Hi Nancy ,
I get the same problem when I switch to Incognito mode on Chrome. Here it is stuck trying to upload a 1.1 Mb file:

I get a different problem when I use the Dropbox app on Windows. I can open up my Dropbox folders in the Windows Explorer, and copy files from another Windows Explorer folder. This can often work, but I also get problems where I tell Dropbox to "Sync now" with the servers via a drop-down menu link:

In this case the syncing can also take extremely long. At least it runs in the background when I do this, so that eventually it gets uploaded. But sometimes it's taking too long for my immediate nneds, so I switch to the browser version ... and then I switch again if what I'm using starts to slow down ...

Hi Megan ,

I'm not able to switch to another network right now, but may be able to later tonight.

But to do further testing, I just copied a 15 MB PDF into a Dropbox folder through the app on my laptop about 25 minutes ago, and it's still syncing. (Speedtest.net does show a significant  slowdown in my upload rate currently to about 0.5 Mbits/sec.) I have Dropbox open on both Chrome and Firefox and am periodically reloading the folder I copied the file to, to confirm that it has not shown up on the server yet. Putting my mouse over the Dropbox icon also shows the sync is still ongoing (along with the Dropbox version):

I can't remember exactly when these problems with Dropbox first started to appear, but it could be as much as 9-12 months ago.
