Many STAs connected to APs have a latency

13

If the connected STAs have a latency, use tool software to collect the environment information and perform comparison tests to troubleshoot the problem. The possible causes of this problem are as follows:
- The user access rate is low.
- The WLAN environment is poor and much interference exists.
- Too many users are connected.
- Too many low access rate users are connected, deteriorating the network performance.
- The cable network is of poor quality.
- The NICs of STAs are of poor performance.

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.

How Many Firewalls Can a User Have?

A user can have a maximum of 200 firewalls. It is recommended that you configure a maximum of 20 inbound or outbound rules for each firewall. If more than 20 inbound or outbound rules are configured, the forwarding performance will deteriorate.
