NAP203: Verschiedene Signalstärken bei verschiedenen SSIDs

Hallo
Ich habe ein merkwürdiges Verhalten bei einem Kunden mit 5 NAP203. Der Kunde hat zwei verschiedene SSID: Test1 und Gast. Nun ist es so, dass praktisch immer Test1 die höhere Signalstärke als Gast hat (2.4GHz). Daher haben Clients im Gastnetzwerk oft Mühe, eine stabile Verbindung herzustellen.
Die Einstellungen sind dieselben, bis eben die Isolierung für das Gastnetzwerk.
Was kann die Ursache sein?
Gruss Mascho

    Hi Mascho,

    Thanks for enable the support function. After checking your sites settings, below are some recommendations for you:

    1. Like you've said through the private message, there're lots of neighbor devices using Wi-Fi, also the railway is 20m far from the AP, which will also generate the signal that interfere the wireless traffic, so we recommend you to enable the DCS function on the issuing AP to let it automatically search for the best/least interference channel for data services. (In the Wi-Fi scanner, only Wi-Fi signals can be displayed, but our DCS function can consider both Wi-Fi and Non Wi-Fi interference, so it's still recommended to enable it instead of fixed channel)

    > For the DCS Settings, it's more recommended to set it schedule at the time where less stations are connected (such as 3:00 A.M), and disable the "DCS client aware",  this way AP can research for the most suitable channel to serve wireless clients.

    2. One of the device "2c:ab:33:1f:19:88" is got frequently kicked out by AP due to low signal strength, since the issuing AP is set wall-mount in its antenna pattern, please make sure that this device is in the coverage of AP that facing towards AP's front panel and less walls and obstacles between them.

    Best Regards,
    Richard

    Hi Mascho,

    In my first analysis, I think it's due to the environment interference in 2.4GHz.

    Usually there are much more Non-Wi-Fi applications (such as Bluetooth, mobile cellular network and others) share the radio frequency around 2.4GHz and generates lots of interference to Wi-Fi services. That's why in some places the Wi-Fi performance in 2.4GHz is worse than in 5GHz radio.


    Could you please enable the "support request" of your Nebula Org/site, and provide the Org/Site Information to me (through private message), so that we can further check our customer's Wi-Fi settings and find out if there's any setting we can optimize?


    Simply access the page as the screenshot below, and enable the "Zyxel Support".


    Best Regards,
    Richard
