  • 1.  Real world expected wifi connection speed

    Posted 06-06-2022 09:43
    Hi, we have recently installed 305c Ap's and 410 Ap's across our entire estate.  Has anyone got some kind of knowledge about what kinds of connection speeds/ bandwidth clients should expect when connected via modern windows 10 laptop?

    At the moment the bandwidth available compared to a wired connection seems very low. Even when my laptop is the only device on wifi.

    For example on Wired I get this from my laptop to a wired server with gbit ports using iperf.
    iperf>iperf3 -c w.x.y.z
    Connecting to host w.x.y.z, port 5201
    [ 4] local A.B.C.D port 1602 connected to w.x.y.z port 5201
    [ ID] Interval Transfer Bandwidth
    [ 4] 0.00-1.00 sec 78.9 MBytes 661 Mbits/sec
    [ 4] 1.00-2.00 sec 80.5 MBytes 676 Mbits/sec

    On wireless I get this

    C:\iperf>iperf3 -c w.x.y.z
    Connecting to host w.x.y.z, port 5201
    [ 4] local A.B.C.D port 28936 connected to w.x.y.z port 5201
    [ ID] Interval Transfer Bandwidth
    [ 4] 0.00-1.00 sec 11.3 MBytes 94.9 Mbits/sec
    [ 4] 1.00-2.00 sec 10.8 MBytes 90.3 Mbits/sec

    Is this typical ?

    Thanks,
    Ewan

    Hi Ewan, with wireless speeds you're going to have to expect to only get about half of what you get with wired, and that's a best case scenario. After that there are several environmental factors that can have a negative impact on your wireless speeds. In general you'll want to look in to Radio Frequency Interference, and try to avoid any metal, glass, or water in the area you want your wireless signal to be. If you think of wireless signal like a sound wave, any obstacles in between where the signal is coming from and where the signal is going will impede your signal somewhat. Metal, glass, water and by extension large amounts of people (since we're basically water to a wireless signal) will all damage (i.e. reflect, refract, generally fragment) the signal more than other obstructions. Also, the more wireless signal in one area, the worse your signal will be, so limiting the number of overlapping wireless signals in your network space will help with interference as well. Hope this helps!
