Troubleshooting WLAN Password Issues

Introduction

This document describes the default user names and passwords of WLAN devices and provides the detailed password recovery method for different passwords. If you forget the login password, refer to this document to recover your password.

Prerequisites

You need to know how to log in to a device through the console port.

Logging In to a Device Through the Console Port

  1. Prepare a console cable.
  2. Install the terminal emulation software on your PC.

    NOTE:

    You can use the terminal emulation software of the operating system (such as the HyperTerminal of Windows 2000/XP) on the PC. If the operating system does not provide terminal emulation software, install third-party terminal emulation software according to user guide or online help of the software.

  3. Use a console cable to connect your PC to the console port of the device. Connect the DB9 female connector of the console cable to the 9-pin serial port on the PC, and connect the RJ45 connector to the console port on the device.
  4. Start the terminal emulation software on the PC, create a connection, select a serial port, and set communication parameters.

    The parameter settings are as follows:

    • Bits per second: 9600
    • Data bits: 8
    • Parity: None
    • Stop bits: 1
    • Flow control: None

    Table 1-1 lists the default settings of a console port.

Logging In to a Device Using Telnet or STelnet and Changing the Console Password

If you have a Telnet or STelnet account with a privilege level of 15 for a device, you can change the console password after logging in to the device using Telnet or STelnet. Then save the configuration of the new password. The following procedure uses Telnet login as an example.

NOTE:

In V200R002 and earlier versions, a user with a privilege level of 3 or higher can change the console password after logging in.

  1. Use a Telnet account with a privilege level of 15 to log in to the device.
  2. Change the console password. The following example changes the authentication mode to password authentication and the password to huawei@123.

    <Huawei> system-view 
    [Huawei] user-interface console 0 
    [Huawei-ui-console0] authentication-mode password 
    [Huawei-ui-console0] set authentication password cipher 
    Enter Password(<6-16>):    //The actual display may be different. 
    Confirm Password: 
    [Huawei-ui-console0] return

  3. Run the save command to save the configuration so that the new password will not be lost after a system restart.

Clearing the Console Password in the BIOS Menu and Changing the Console Password

You can clear the console password in the BIOS menu (if the device provides this function). Then the system can start and load all configurations normally, except that it does not prompt you to enter the console password. After the device starts, change the console password and save the configuration.

  • Clearing the console password brings security risks. Keep the BootROM password safe to ensure system security.
  • You must restart the device to display the BIOS menu, which results in service interruption. Back up service configuration and perform this operation in off-peak hours.
  • If you clear the console password, configure a new password immediately after you log in to the device. Otherwise, you must clear the console password again to log in if the login timeout timer expires or the device restarts.
  • Do not power off the device during the operation.
  1. Use a serial cable to connect a PC to the device and restart the device. When the message "Press CTRL+B to enter BIOS menu" is displayed, press Ctrl+B and enter the password (admin@huawei.com by default) to display the BIOS main menu.

    For details on how to connect a PC to the device with a serial cable, see Logging In to a Device Through the Console Port.

    The BootROM password may vary in different software versions. For details, see Understanding the List of Default User Names and Passwords.

  2. Clear the console password.

    1. Enter the number of the Clear password for console user option in the BIOS menu to clear the console password.
    2. Enter the number of the Boot with default mode option to start the system with the default mode.

  3. Log in to the system through the console port without entering the password. Change the console password. The following example changes the authentication mode to password authentication and the password to huawei@123.

    Different software versions provide different commands for changing the authentication password:

    • V200R002 and earlier versions: set authentication password [ cipher password ]
    • V200R003 and later versions: set authentication password cipher
    <Huawei> system-view 
    [Huawei] user-interface console 0 
    [Huawei-ui-console0] authentication-mode password 
    [Huawei-ui-console0] set authentication password cipher 
    Enter Password(<6-16>):    //The actual display may be different. 
    Confirm Password: 
    [Huawei-ui-console0] return

  4. Run the save command to save the configuration so that the new password will not be lost after a system restart.

Changing the Password of a Fit AP on an AC

V200R005C10 and Earlier Versions

A Fit AP supports only one local user account, which can be a console, Telnet, or SSH account.

If the password of a Fit AP is lost but the AP has connected to an AC successfully, change the password or restore the default password:

  • Run the wlan ap username command on the AC to configure a new user name and password, and deliver the configuration to the Fit AP.
  • Run the undo wlan ap username command on the AC to restore the default user name and password, and deliver the configuration to the Fit AP.
NOTE:

The preceding operations may affect other APs connected to the AC. For example, if configuration needs to be delivered to other APs or new APs connect to the AC, the password configuration delivered from the AC will change the user name and password on these APs.

Configuring a Password for a WS6603

A super administrator or administrator can change the password of itself or a user with a lower level. When changing the password of a user with a lower level, the super administrator or administrator does not need to enter the old password of this user.

A common user or operator can only change its own password and must enter the old password before setting a new password.

  • Create a user account operator and set the user level to operator, number of login attempts to 2, and appended information to operator.
    WS6603>enable
    WS6603#terminal user name
      User Name(length<6,15>):operator
      User Password(length<6,15>): 
      Confirm Password(length<6,15>): 
      User profile name(<=15 chars)[root]: 
      User's Level: 
         1. Common User  2. Operator  3. Administrator:2
      Permitted Reenter Number(0--4):2
      User's Appended Info(<=30 chars):operator
      Adding user succeeds
  • Use an administrator account to log in to the system, and set the password for the operator user to huawei@123.
    WS6603>enable
    WS6603#terminal user password
      User Name(length<6,15>):operator
      New Password(length<6,15>): 
      Confirm Password(length<6,15>):
