speedtest I got 500mbps. But when I use , or download it dont get 500mbps. Only 200-300mbps
(1) Your local internet exchange is shared between users. The congestion when you speedtest-ed maybe lower than when you are downloading.
(2) The "weather" and network conditions when you speedtest-ed and when you are downloading are not necessarily the same.
(3) The IP network path between your testing device and speedtest server is NOT the same IP network path taken between your downloading device and your download server. You cannot expect the same experience of driving from Johor Bahru to Arau and of driving from Johor Bahru to Kota Bharu, eventhough both passes through Kuala Lumpur.
(4) What you should use speedtest for, is to test what is the maximum capability of network connection between your testing device and your ISP. Can it reach your subscribed speed at all in the first place? For example, assuming you are using ethernet cable, if at any time and against multiple speedtest servers, you can only get maxed 400Mbps of a 500Mbps subscription, then you already determine that either your testing device is crap or router is crap or your fibre line is crap.
But since you already proven that you are able to get 500Mbps, even if only just once, that means there is already no issue between your test device to your router to your ISP and to your speedtest server (unless wear and tear over time).
Apart from the confidence that the path up to ISP is "500Mbps-rated", everything else are variables that impact your download speed.
