Why Upload Slower Than Download
Three weeks ago, I had Gigabit FIOS installed, but I have never been able to get gigabit speeds going both ways. I always get 900+ Mbps UPLOAD but never more than 300 Mbps DOWNLOAD.
But, I get 900/900+ Mbps between the Router and the Server every time, *AND*, here's the real kicker: I get 900/900 Mbps from the desktop if I run in Safe Mode. So, I've concluded that it's not a downstream hardware or a FiOS server issue, but rather something to do with my onboard LAN setup.
I have tried the obvious things: (1) Different Ethernet drivers from Microsoft, Realtek, and ASRock; (2) Different cables (CAT5e); (3) Played around with Adapter settings such as 'Receive Buffers' (512) and 'Speed & Duplex' (1.0 Gbps Full-Duplex). None of this has helped. I am running Win 10 Pro 64-bit.
So I guess what I am asking is: What do you think it means that I can make Gigabit FIOS work in Safe Mode but not from the normal desktop? Hoping you could give me some guidance on where to look for the culprit.
Genuinely, thank you for your help!
