Hey all, here's a wild one for you, So a relative of mine has a laptop that has a connection speed issue that limits download to roughly 9.7Mb/s. My first thought was to confirm speed and duplex, and the laptop was originally connected to a 10/100 switch, so we tried switching it over to wifi to see if that would work. No dice. About this laptop: Dell Inspiron 5559 i5-6500u 8GB RAM 1TB hard drive Realtek PCIe FE Family Controller (realtek wired and wireless adapter) The laptop itself should have no issues using their full 100/10 speed, so I continued troubleshooting Things I have tried so far: Updating realtek drivers through windows Updating realtek drivers via realtek's website Finding/downloading drivers via Dell's website Changing Speed and Duplex settings This guide to remove windows cap speeds (from googling around) Anyone have ideas? I'm out so far and but will continue my googling.

It seems there might be some confusion between megabits and megabytes. One byte equals eight bits, so a 100 Mbps connection translates to roughly 12 MB/s download. That’s quite close to what you mentioned!

I understand my figures and noted that Fast.com uses MegaBITS each second, not megabytes. That was my initial concern. The graph also becomes more detailed since it's just this machine on the network. When he works, he achieves the ISP speed (100/10 Mbps), but drops to 10mbps at home.
