WiFi is open to interference. I can't guess if all the devices are clean either. That is I fixed a few last week and one had malware, the other used a proxy (owner didn't know why) and the other had an overreaching antivirus suite.
That and how WiFi is shared.
But let's get something under control today. Windows 10. I always turn the following off.

Hi everyone,
When running a speedtest on my home wifi network - one computer shows 35MB (download) and on two other PCs and Cell Phones - I only get 3MB .... (?!) how come? Could it be a router settings?
* The 2 other computers that show only 3MB download have a network card that supports N and have already shown high-speed abilities in the past.
