Ask him to undo it, and see if you get any complaints from the office staff.
I help with computer questions at my local senior center and we just recently got wireless internet. The company supervisor said that We would have 120 Mbps upload and down. Then when installation is finished the tech. tells me that it will be 14 Mbps wireless and 120 Mbps for the three office ports to reduce the load. The load will be at max about three Chromebooks and five phones. Why throttle?
