Recently, I upgraded to 50/25 fios from 25/25 and installed a new Rev. I router. Since then I have had upload speed problems, and Verizon even sent me a replacement router. All connections are hard wired using Cat 5e or Cat 6 cables.
Today, I tried to upload some large files (2-4 GB) and it was taking anywhere from 3 to 12 hours, indicating a very slow upload speed, probably less than 1 meg. I tried several different file transfer services and FTP servers, and all were glacially slow. However, since my internet speed looks fine when testing using the offical Verizon site (to the closest server), they won't look into the matter any more beyond resetting my ONT, which didn't help.
When I test using any other web site, the upload speed is always very fast (over 50 meg), but upload is always far below what I should be getting (5 meg or lower). If I test using the official Verizon site connecting to one of their servers farther away, the download speed stays the same, but the upload speed drops drastically. Verizon tech support didn't care about this since they only consider the test to their closest server as valid.
Also, Verizon has another speed test web site (link below) that they refuse to acknowledge the existence or the results of that consistently shows that I have low upload speeds. As usual, my download speed is fine.

My upload speeds were never a problem until I "upgraded" to a faster internet speed. I need to move a lot of large files often and need this to work better, but it seems like Verizon techs just want to get rid of me because it checks out on their end and it passes the only speed test that they will consider.
Any ideas what else I can try? I guess I could reinstall my old "slow" Rev. D router, but that seems like a step backward, and I would lose the gigabit LAN and N wireless improvements.
