I just noticed that my Mac Mini is only getting around 6-7 Mbps when running a speed test, so I started checking my gear. First, I have Gigabit Fios. I have Cat-6 running to Gigabit switches throughout the house. In the upstairs room where my Mini is, I used to get about 500 Mbps on a speed test (the Mini was never as fast as other computers on the network) and between 800 - 960 Mbps on a Windows 10 desktop that is connected to the same switch. Right now, I am only getting 7-8 Mbps on both the Mini and the Windows desktop on that switch. Downstairs, my iMac is getting around 800-900 Mbps so that is good. My iPhone and iPad, over wireless of course, are getting their average speeds of about 300-400 Mbps and my Macbook Pro is getting its average speeds as well. My Apple TV, which is downstairs on a different switch, is getting around 90 Mbps, but it used to get over 900 Mbps. And my XBox One, which is on the same switch as the Apple TV, is getting close to 600 Mbps, which is where it usually tops out. So I would have thought it was the switch upstairs, but my Apple TV, on a different switch, is also getting much slower speeds than it usually does. I have rebooted the computers, the router and the switches and the speeds are still slow. The only changes I've made to my network recently was to add two HomePods and a Wemo Bridge so that I can control my Wemo Light Switches with the HomePods through Homekit. But my question is, what would cause my speeds to drop so significantly on some devices, but not on others?
