I'm getting about 40Mbps transfer rater over WiFi (from phone to Linux). Is it that slow because of the SDCard on the phone?



  • I have a WiFi connection which, in the settings, says:

    Transmit link speed
    866Mbps

    Receive link speed
    780Mbps

    I've installed PowerFTP on my phone and transferred a large video file (about 40 min.) from my Android (Pixel 5a) phone to my Linux computer. My network is a 1Gbps all around (switch, NICs, WiFi router) except for the WiFi transmission itself (obviously).

    The transfer rate shown by PowerFTP is around 5Mb/s (or ~40Mbps).

    Why is that transfer rate so low? Is there something else limiting the speed along the way?


    Update:

    My Network looks more or less like this:

    +-------+        +-------------+        +--------+        +------+
    |       |        |             |        |        |        |      |
    | Phone || WiFi Router || Switch ||  PC  |
    |       |  WiFi  |             |  LAN   |        |  LAN   |      |
    +-------+        +-------------+        +--------+        +------+
    ~700mbps         ~700Mbps  1Gbps          1Gbps            1Gbps
    

    The LAN has a switch and that connection is local (as in 192.168.x.x).

    There are other devices on the WiFi (3 phones, a laptop--which was off when I tested the above).

    Of course, I can see some WiFi devices from my neighbors... so I understand there can be interference there.



  • that's limitation from PowerFTP. before buying ask https://powerftp.medialux.app if pro version will increase speed (not sure about this)
