I've got a 250mb down/20mb up fiber connection at home.
Few days ago I've noticed that my wifi slowed down a bit after upgrading from 17.1 to 17.2 and installing all updates.
I haven't had much time to investigate it so far, but today I found a moment, and I don't know what's the issue.
All internet speed tests show me that the maximum I can squeeze out of this connections is 111mb.
I tried it on the same laptop but on Windows 8.1 and I can get up to 212mb, same thing on a macbook pro 2014.
Another problem is that when I download something on that laptop at the 3/4 MB/s then it affects other devices in the home network quite badly. Connections are either very slow or they are even dropped.
My laptop is Lenovo W530
