The numbers associated with speeds can be confusing. In my case the ISP provides 15 Mbps download speed. When I download a large file, it downloads using the full speed.
You are indicating you have a 110 Mbps download speed. Have you done a Speed Test on your systems to see how they compare? You also have to make sure you are not looking at MBps vs. Mbps since on is 8 times the other.
Your actual configuration is important. Are you using wireless on that one system, and is it connected to some type of Router? If it is wireless, how strong is the signal?
If you are not sure what devices you have onboard, you can check the device manager or use msinfo32.exe to list them.
