Why is the signal strength that a STA receives from an AP weak
The possible causes are: - The transmit power of the AP is low. In this case, increase the transmit power. - The antenna system of the AP (indoor DAS AP) is not properly deployed. 1. The output power on antenna interfaces is low because the AP connects to excess antennas. Or the feeder lines are too long. 2. The passive devices (combiner, splitter, and coupler) do not comply with design principles or specifications or are not properly connected. 3. The passive devices have unloaded interfaces. - The STA is far away from the AP's antennas, so the signal loss is large. - Signals are blocked by a beam, post, concrete wall, metal door, or other obstacles between the STA and antennas. In this case, change the antenna installation positions.

How to configure the STA blacklist on WLAN devices
A STA blacklist contains MAC addresses of STAs that are not allowed to connect to the WLAN. To forbid some STAs from connecting to the WLAN, you can configure a STA blacklist. You can configure a global STA blacklist for APs, and the blacklist takes effect on all VAPs. You can also configure a STA blacklist for specified VAPs. If an AP and a VAP are configured with the blacklist or whitelist function, a STA can connect to the WLAN only when it is permitted by both the configuration on the AP and VAP. - For V200R003 and V200R005, you can perform the following steps to configure a STA blacklist for specified APs on an AC or a Fat AP: 1. Run the sta-blacklist mac-address command in the WLAN view to add specified MAC addresses to the STA blacklist. The variable mac-address specifies the MAC addresses in the STA blacklist. 2. For ACs: run the sta-access-mode ap { { start-id [ to end-id ] } &<1-10> | all } blacklist command in the WLAN view to set the access control mode to the STA blacklist for a specified AP. The variable start-id and end-id specify the AP ID range. For Fat APs: Run the sta-access-mode blacklist command in the WLAN view to set the access control mode to the STA blacklist. 3. Run the commit { all | ap ap-id } command in the WLAN view to deliver configurations to the APs (applicable only to the AC). The variable ap-id specifies the AP ID. - For V200R003 and V200R005, you can perform the following steps to configure a STA blacklist for specified VAPs on an AC or a Fat AP: 1. Run the sta-blacklist-profile { name list-name | id list-id } command in the WLAN view to create a STA blacklist profile and display the STA blacklist profile view. The variable list-name specifies the STA blacklist profile name, and list-id specifies the STA blacklist profile ID. 2. Run the sta-mac mac-address command in the STA blacklist profile view to add the MAC address of a STA to the STA blacklist profile. The variable mac-address specifies the MAC addresses in the STA blacklist. 3. Run the service-set { id profile-id | name profile-name } * command in the WLAN view to display the service set view. The variable profile-id specifies the service set ID, and profile-name specifies the service set name. 4. Run the sta-access-mode blacklist command in the service set view to set the access control mode for VAPs to the STA blacklist. 5. Run the set view sta-blacklist-profile { name list-name | id list-id } command in the service set view to bind a STA blacklist profile for the service set. The variable list-name specifies the STA blacklist profile name, and list-id specifies the STA blacklist profile ID. 6. Run the commit { all | ap ap-id } command in the WLAN view to deliver configurations to the APs (applicable only to the AC). The variable ap-id specifies the AP ID.

How to disable wireless signals of a WLAN device
To save energy or ensure security, run the following commands to disable AP radios or WLAN services: 1. Disable a specified radio. - For AC+Fit AP networking V200R005: [AC6605] wlan [AC6605-wlan-view] ap 0 radio 0 [AC6605-wlan-radio-0/0] undo radio enable For V200R006: [AC6605] wlan [AC6605-wlan-view] ap-id 1 [AC6605-wlan-ap-1] radio 0 [AC6605-wlan-radio-1/0] radio disable Warning: This action may cause service interruption. Continue?[Y/N]y - For Fat APs V200R005: [Huawei] interface wlan-radio 0/0/0 [Huawei-Wlan-Radio0/0/0] undo radio enable For V200R006: [Huawei] interface wlan-radio 0/0/0 [Huawei-Wlan-Radio0/0/0] radio disable Warning: This action may cause service interruption. Continue?[Y/N]y 2. Prevent users from accessing the WLAN in the specified time range. For V200R005: [AC6605] wlan [AC6605-wlan-view] auto-off service ess service-set id 0 start-time 01:00:00 end-time 07:00:00 //Disable the service set with ID 0 from 1:00:00 to 7:00:00. For V200R006: [HUAWEI]wlan [HUAWEI-wlan-view]vap-profile name vap1 [HUAWEI-wlan-vap-prof-vap1]auto-off service start-time 1:00:00 end-time 7:00:00 //Disable a VAP from 1:00:00 to 7:00:00. 3. Disable an AP radio in a scheduled time using the auto-off service radio command (V200R005). For AC+Fit AP networking: [AC6605] wlan [AC6605-wlan-view] auto-off service radio ap-id 0 radio-id 0 start-time 1:00:00 end-time 7:00:00 //Disable radios 0 of AP 0 from 1:00:00 to 7:00:00. For Fat APs: [Huawei] wlan [Huawei-wlan-view] auto-off service radio interface wlan-radio0/0/0 start-time 1:00:00 end-time 7:00:00 //Disable AP interface wlan-radio0/0/0 from 1:00:00 to 7:00:00.
