Hi,
I have been a Dropbox user since it is lunched. I have never had an issue with upload or download speeds. Recently for the last month I am having trouble uploading my files. It takes 10-20 times more time to upload. Sometimes more.
I check my internet speed and there is no issue with my upload speed. I also know there is no problem because when I use WeTransfer or other file sharing apps it goes up super fast.
I also check the network settings and there is no bandwidth limitations there too.
I have talked with support and they told me to restart my modem and I have done it 3 times and still no improvement.
One thing I notice is when I resume synching and check my speed again it drops significantly. So it does use my bandwidth but it doesn't translate into the speed it suppose to have.

This is a very big issue for me, I use Dropbox for work constantly and this has to be resolved.
Thank you for help!
