Resetting to the Default Configuration
If you forget the password that allows you to configure the access point, you may need to completely reset the configuration. On 1100 and 1200 series access points, you can use the MODE button on the access point or the web-browser interface. On 350 series access points, you can use the web-browser or CLI interfaces.

Note The following steps reset all configuration settings to factory defaults, including passwords, WEP keys, the IP address, and the SSID. The default username and password are both Cisco, which is case-sensitive. Using the MODE Button
Follow these steps to delete the current configuration and return all access point settings to the factory defaults using the MODE button.

Note You cannot use the mode button to reset the configuration to defaults on 350 series access points. To reset the configuration on 350 series access points, follow the instructions in the "Using the Web Browser Interface" section, or in the "Using the CLI" section.

Step 1 Disconnect power (the power jack for external power or the Ethernet cable for in-line power) from the access point.
Step 2 Press and hold the MODE button while you reconnect power to the access point.
Step 3 Hold the MODE button until the Status LED turns amber (approximately 1 to 2 seconds), and release the button.
Step 4 After the access point reboots, you must reconfigure the access point by using the Web-browser interface or the CLI.

Note The access point is configured with the factory default values including the IP address (set to receive an IP address using DHCP). The default username and password are Cisco, which is case-sensitive. Using the Web Browser Interface
Follow these steps to delete the current configuration and return all access point settings to the factory defaults using the web browser interface:

Step 1 Open your Internet browser. You must use Microsoft Internet Explorer (version 5.x or later) or Netscape Navigator (version 4.x).
Step 2 Enter the access point's IP address in the browser address line and press Enter. An Enter Network Password screen appears.
Step 3 Enter your username in the User Name field.
Step 4 Enter the access point password in the Password field and press Enter. The Summary Status page appears.
Step 5 Click System Software and the System Software screen appears.
Step 6 Click System Configuration and the System Configuration screen appears.
Step 7 Click the Reset to Defaults button.

Note If the access point is configured with a static IP address, the IP address does not change.
Step 8 After the access point reboots, you must reconfigure the access point by using the Web-browser interface or the CLI. The default username and password are Cisco, which is case-sensitive. Using the CLI

Follow the steps below to delete the current configuration and return all access point settings to the factory defaults using the CLI.
Step 1 Open the CLI using a Telnet session or a connection to the access point console port.
Step 2 Reboot the access point by removing power and reapplying power.
Step 3 Let the access point boot until the command prompt appears and the access point begins to inflate the image. When you see these lines on the CLI, press Esc: Loading "flash:/c350-k9w7-mx.v122_13_ja.20031010/c350-k9w7-mx.v122_13_ja.20031010" ...########################################################################### ################################################################################ ################################################################################ ####################

Step 4 At the ap: prompt, enter the flash_init command to initialize the Flash. ap: flash_init Initializing Flash... flashfs[0]: 142 files, 6 directories flashfs[0]: 0 orphaned files, 0 orphaned directories flashfs[0]: Total bytes: 7612416 flashfs[0]: Bytes used: 3407360 flashfs[0]: Bytes available: 4205056 flashfs[0]: flashfs fsck took 0 seconds. ...done initializing Flash.

Step 5 Use the dir flash: command to display the contents of Flash and find the config.txt configuration file. ap: dir flash: Directory of flash:/ 3 .rwx 223 <date> env_vars 4 .rwx 2190 <date> config.txt 5 .rwx 27 <date> private.config 150 drwx 320 <date> c350.k9w7.mx.122.13.JA 4207616 bytes available (3404800 bytes used)

Step 6 Use the rename command to change the name of the config.txt file to config.old. ap: rename flash:config.txt flash:config.old

Step 7 Use the reset command to reboot the access point. ap: reset Are you sure you want to reset the system (y/n)?y System resetting..Xmodem file system is available. flashfs[0]: 142 files, 6 directories flashfs[0]: 0 orphaned files, 0 orphaned directories flashfs[0]: Total bytes: 7612416 flashfs[0]: Bytes used: 3407360 flashfs[0]: Bytes available: 4205056 flashfs[0]: flashfs fsck took 0 seconds.

Note The access point is configured with factory default values, including the IP address (set to receive an IP address using DHCP) and the default username and password (Cisco).
Step 8 When IOS software is loaded, you can use the del privileged EXEC command to delete the config.old file from Flash. ap# del flash:config.old Delete filename [config.old] Delete flash:config.old [confirm] ap#
