Speed Confusion

I've got an XR450 Gaming Router and a 1Gbps connection through i3 Broadband. 

 

When I run a speedtest through speedtest.com or fast.com, my download speed comes in in the mid 900's. When I run a speedtest through DUMAOS, my download speed comes in at around 500.

 

Can anyone explain the discrepancy and if it's a problem?

 

TIA

  • As above, the in-built test can be inaccurate but as you can see from speedtest.net it isn't limiting you so you can ignore it

    Mostly due to the DUMAOS maybe picking a slower speed server near you and we can't pick it ourselves. I've seen this as well on my XR routers. OS  speed difference. Why I've always preferred using ooklas installable speedtest app on a PC and testing over ethernet. Get more accurate results.
