Procedure

1. Check the number of STAs that have associated with the AP.

   • For V200R005:

     <AC6605> display station assoc-num ap 0
       Number of station: 100  //100 STAs have associated with AP 0.

   • For V200R006 and later versions:

     <AC6605> display station ap-id 0
     Rf/WLAN: Radio ID/WLAN ID
     Rx/Tx: link receive rate/link transmit rate(Mbps)
     ------------------------------------------------------------------------------
     STA MAC          Rf/WLAN  Band  Type  Rx/Tx      RSSI  VLAN  IP address   SSID
     ------------------------------------------------------------------------------
     14cf-9208-9abf   0/2      2.4G  11n   3/8        -70   10    10.10.10.253 tap1
     ...
     ------------------------------------------------------------------------------
     Total: 100 2.4G: 70 5G: 30  //100 STAs have associated with AP 0.

2. Check the maximum number of STAs that can associate with the AP in the product documentation of the corresponding AP model, and compare it with the actual number of STAs associated with the AP. If the number of STAs associated with the AP has reached the maximum, expand the network capacity. If the number of STAs associated with the AP does not reach the maximum, increase the maximum number of STAs that can associate with a VAP.
    NOTE:

   You can log in to Huawei enterprise support website (http://support.huawei.com/enterprise) to obtain the product documentation of the specific AP model.
   Increase the maximum number of STAs that can associate with a VAP.

   • For V200R005:

     <AC6605> display service-set id 0
     ...
       User isolate                     : disable
       Type                             : service
       Maximum number of user           : 64  //A maximum of 64 STAs can associate with a VAP.
       Association timeout(min)         : 5
     ...
     <AC6605> system-view
     [AC6605] wlan
     [AC6605-wlan-view] service-set id 0
     [AC6605-wlan-service-set-ess1] max-user-number 70  //Increase the maximum number of STAs that can associate with a VAP to 70.
     

   • For V200R006 and later versions:

     <AC6605> display ssid-profile name ssid-0
     ...
     SSID hide                   : disable
     Association timeout(min)    : 5
     Max STA number              : 64  //A maximum of 64 STAs can associate with a VAP.
     Reach max STA SSID hide     : enable
     Legacy station              : disable
     ...
     <AC6605> system-view
     [AC6605] wlan
     [AC6605-wlan-view] ssid-profile name ssid-0
     [AC6605-wlan-ssid-prof-ssid-0]max-sta-number 70  //Increase the maximum number of STAs that can associate with a VAP to 70.
     

   Adjust the maximum number of STAs that can associate with an AP. To ensure that services run normally, it is recommended that a maximum of 30 STAs associate with a single-band AP, and a maximum of 50 STAs associate with a dual-band AP.

3. Enable the STA to reconnect to the WLAN. If the STA still fails to connect to the WLAN, run the display station online-fail-record mac mac-address command on the device in V200R005, or the display station online-fail-record sta-mac mac-address command on the device in V200R006 and later versions to check for other STA online failure causes.
