Our company just got a bandwidth increase to 500mg. Whenever we run a speed test, we can only get up to 200 mg up or down. Now we are using SG350X - 48 port Managed Cisco switches and a Cisco router, both support up to 1000mg. We put both devices on auto-negotiate and ran a speed test, still got 200 up and down. We set both to manual - 1000mg / full got the same speeds. We plugged a laptop directly into the router and got the same speed. If we plug the laptop directly into the dmarc, put the laptop in safe mode and run the speed test, we get at least 400 up and down, so our ISP says they are good. We can't work like that as a company. Does anyone have any idea, why we are unable to get the speeds. Also we tested the laptop connected to the switch in safe mode with no success.
