Windows 10: Testing Wifi speed

    Testing Wifi speed


    How can I test the speed of my laptop's 802.11ac wifi connection?

    I would like to know how fast I can retrieve (but not store) data from my Synology NAS, or maybe send data to the NAS.

    The laptop has (2x2) and connects at 867 mbps. I should be able to transfer data at half this speed say 433Mbps, but when I use Windows 10 to copy a file the speed barely reaches 300Mbps, perhaps because the file is being written to the laptops SSD.

    Is the connection between you and the NAS, wifi?

    Also there are other overheads. TCPIP sends various ack, nak and checksums back and forth so it isn't only your data being sent. That should account for around 10% reduction.

    You could turn on jumbo frames to reduce this.

    It is not particularly easy to test WiFi speed as there is often some other hardware limitation(s), also higher errors with WiFi than Ethernet which means data being resent.

    I have A Synology NAS box, wired 1 Gbs network interfaces hardware, and the limitation is around 300-400 Mbs. That is a limit of hardware probably the HDDs(WD Red) or other NAS box hardware.

    I got marginally more using up to SMB2 & large MTU.

    When I had 100 Mbs network cards/router, same NAS box, I got about 80-100 Mbs wired.

    Basically there is probably nothing wrong with your setup, looks about right to me for Wireless. Obviously try wired 1 Gbs and compare.

    A 1Gbps wired connection from my desktop PC to the NAS via the same router (acting just as a Wifi access point and switch) gives me 888Mbps or so during a file copy. I am just curious as to why the laptop does not get nearer to half the connection speed which this document made me this document https://www.intel.com/content/dam/ww...or-dummies.pdf made me think I should be able to achieve.

    It's about right for Wireless a max real speed of a third or so of the connection speed. You are expecting too much of Wireless.

    A third is the number I use. Going way back to Wireless G it was about 18 Mbs real for 54 Mbs connection speed.

    Yeah - the 50% is rarely ever met in real life (your 1/3rd rule is a pretty good guide).
