Low connection Speed on NWA50


I recently purchased a NWA50 for testing purposes. I planned to install 3 APs in my house to have wifi all over.
Now I encounter the problem that the NWA50 only assigns my mobile with 96mbps to the 5Ghz WiFi. 
I changed cable. 

I connected an other APs (not zyxel) to the same cable and got assigned 400mbps.

Why is the NWA50 only giving me such a low speed? 
Distance is directly in Front with 1-5 meteres. Value stays the same. 

i set up the ap as low density in nebula. 

Any ideas?

    Hi @Polytox


    Welcome to Zyxel Community!

    There are many factors impact the result such as environment, connection quality …

    Ensure your AP and wireless clients are all upgrade to latest driver version and follow the pdf file in the article to setup/check the environment.



    If the performance still not as expectation, please enable the Zyxel support at Help > Support request > Invite Zyxel support as administrator, save the changes for us to check. And provide the Org and Site name, thank you.

    These APs are designed to be installed on the ceiling, so if you are not using them like that, it might give you a false reading.

    Also a big mistake is to leave the AP radio power on default values.
    What I suggest to do is to start with a relatively low value (eg. 5-6 dBm) for the 2,5GHz band, and set the 5 GHz radio to about 5-6 dBm more, in this case that would mean 11 dBm. If the area covered will be too small, you can gradually go up by 1-1 dBm.
    THis ensures you have a similar, but rather a slightly higher coverage on 5 GHz, so your clients will be more likely to associate to this radio, thus their connection rate will always be better.

    @Peppino it's installed in the ceiling. It Was the AP not using 80MHZ when dfs active. Bella again pushed the settings again and it Was working. For now I disabled dfs usage.
