Why does the SSID of an AP disappear intermittently on a STA when the AP is running normally

10

Possible causes are:

-Automatic channel adjustment is enabled on the AP, so the AP continuously adjust channels to obtain the best radio performance. The radio module of the AP is reset when the channel is changed. You can run the channel-mode fixed command in the radio profile view to solve this problem.

-The STA is far from the AP or is blocked by an obstacle. As a result, the receive signal strength on the STA is weak.

1. Automatic channel adjustment is enabled on the AP, so the AP continuously adjusts channels to obtain the best radio performance. The radio module of the AP is reset when the channel is changed. You can run the channel-mode fixed command in the radio profile view to solve this problem. 2. The STA is far from the AP or is blocked by an obstacle. As a result, the wireless signal received on the STA is weak.

Why does a STA fail to discover the SSID of an AP when the AP software version is correct and has correct WLAN configuration
1. The SSID hiding function is enabled using the ssid-hide command in the service set view. In this case, run the undo ssid-hide command in the service set view to disable the SSID hiding function. 2. When the device functions as an AC, you can run the display ap-run-info command to check whether the AP works properly.

How to isolate STAs associated with the same SSID of an AP
Huawei APs support local Layer 2 isolation. After Layer 2 isolation is enabled, local STAs cannot communicate at Layer 2, and data can only be transmitted between uplink ports and VAP ports. To enable Layer 2 isolation, configure it on an AC.

How can I separate two STAs that connect to the same AP and SSID
Huawei APs support Layer 2 isolation. When Layer 2 isolation is enabled, STAs cannot communicate at Layer 2. Only the upstream interface and virtual access point (VAP) interface can exchange data. You can enable Layer 2 isolation on an AC.

STAs are associated with other APs in multi-AP scenarios
In multi-AP scenarios, STAs may be associated with other APs when a long Beacon frame transmission interval is set. STAs obtain information about peripheral WLANs in either of the following ways: - Passive scan: STAs scan Beacon frames sent by surrounding APs to obtain WLAN information. - Active scan: STAs actively send Probe Request frames and receive Probe Response frames to obtain wireless signals. STA can actively or passively scan surrounding WLANs. When a STA passively scans WLANs and APs are densely deployed, the STA can receive Beacon frames from another AP but not the nearest AP, and perform association.
