I’m trying to determine the maximum data connection speeds of our computers and network. I hope that is worded correctly.
We have Comcast internet with a published 500Mbps service. Out of the Comcast router, our feed goes to an Araknis router, then a switch, and then via ethernet to the computers plus to Ruckus APs for Wifi. I think this old beginner has that described correctly.
I thought we were falling way short of the published service speed since my iMac was showing a little less than 100 Mbps whether using Ethernet or Wifi. Measured speed by Ookla and Comcast speed tests.
But then I checked my wife’s computer on both Ethernet and Wifi. Both were around 550 Mbps on her 2018 iMac. So that would say Comcast is delivery the published speed.
I then tried my 2019 MacBook Air travel computer. It is showing speeds around 135 Mbps over Wifi.
And then my computer which is a 2015 iMac brings up the rear at 90 Mbps on both Ethernet and Wifi.
I now suspect that either each computer has a maximum connection speed or we are losing speed through the network. But I have no clue where to start to educate myself. I assume I should have found a good site with a search but I failed.
Any education or site references will be very much appreciated.
