Common Causes

This fault is commonly caused by one of the following:

  • The wireless network adapter on the STA is faulty.
  • No antenna is installed on the AP.
  • A channel conflict occurs.
  • A low radio signal power is set for the AP on the AC.
  • Other wireless devices interfere with the radio signals from the AP.

Troubleshooting Procedure

Context

NOTE:

Saving the results of each troubleshooting step is recommended. If your troubleshooting fails to correct the fault, you will have a record of your actions to provide Huawei technical support personnel.

Procedure

  1. Check whether the wireless network adapter of the STA is working properly.

    Use another wireless network adapter to check whether STAs are logged out frequently.

    • If no STAs are logged out unexpectedly, the wireless network adapter of the original STA fails. Replace it with a new wireless network adapter.
    • If STAs are logged out frequently, go to step 2.

  2. Check that an antenna is installed on the AP.

    Check whether an antenna is installed on the AP.

    • If no antenna is installed, install an antenna on the AP.
    • If an antenna has been installed, go to step 3.

  3. Check whether a channel conflict occurs.

    Use NetStumbler to check whether a channel conflict occurs. If many radio signals are transmitted over channel 11 but no radio signal is transmitted over channel 1, run the channel command in the radio view to change the AP radio channel from channel 11 to channel 1. If the fault persists, go to step 4.

  4. Check the radio signal power configured for the AP on the device.

    Run the display actual channel-power command in the radio view on the device to check the channel and power parameters of a specified radio.

    NOTE:

    Level 0 indicates the maximum power. Level 1 is 1 dBm less than level 0; level 2 is 2 dBm less than level 0; and so on. A higher power level indicates a lower power. When the transmit power level is set to 12, 13, 14, or 15, the POWER-LEVEL field is always displayed as 12.

    • If the POWER-LEVEL field is displayed as 12 or a value approximate to 12, the current transmit power of the radio is too low. Consequently, STAs are logged out frequently. Run the power-level command to set a lower transmit power level for the radio.
    • If the POWER-LEVEL field is displayed as 0 or a value approximate to 0, the current transmit power of the radio is within the specified range. Go to step 5.

  5. Check whether there are other wireless devices.

    Check whether there are other wireless devices, for example, a working microwave oven. Other wireless devices will interfere with radio signals from the AP, causing STAs to be logged out frequently.

    • If there are other wireless devices, turn off these devices and connect STAs to the AP again.
    • If there is no other wireless device, go to step 6.

  6. Collect the following information and contact technical support personnel:

    • Result of the preceding procedure
    • Trap, log, and configuration information
