    Hi everyone. We are facing an issue. Some APs (3/10) in 1 location don't give speed above 100.mbps. wired speed is ok. Clients are connecting at 5ghz. What can be the issue. Cables have been tested, replaced and APs have also been replaced.

    What are you using to test speed?  

    Check the client rx and tx by running "show ap debug client-table ap-name <name of ap>" on the commandline to ensure they are not negotiating lower transmit rates on that AP.

    We are using speedtest.net

    I will check the command today but same client is getting correct speed from other APs in that location.

    You have to find out what is similar between the clients on those three APs.  That command is just another thing to check.

    I checked with my mobile and laptop on all the APs one by one.there is no other user at the moment.

    I would recommend to use iperf in order to test physical network connectivityZ
    There might be limits in the passive part such as, patch cable, patch pannels, etc.

    What are your client capabilities? how many spatial streams does the client have? what SNR does the client have? what channelwidth are u using? what type of AP? what firmware level?

    Respect that your  real throughput will never be higher then approx.. 50% of the modulation speed.
