Question about Linksys (WRT54GC) Router
What is Management Mode? How do I recover my router if something goes wrong and I cannot access the Setup pages to upgrade firmware?
Posted by Anonymous on
What is Management Mode? If you encounter an irrecoverable condition with the WRT54G v5, you can use Management Mode to recover the router by uploading a new firmware image. In Management Mode, the router will have just enough functionality to load a newer firmware. You should be able to recover the router is most situations. When will the WRT54G v5 enter Management Mode? The WRT54G v5 will enter Management Mode when: * The router's firmware is corrupt (for example, when the router's Power light is blinking), OR * When the router has been reset incorrectly using the following steps: 1. Unplug the power cord. 2. Press and hold the Reset button. 3. Plug power cord back in (Reset button still held in). 4. Wait about 5-10 seconds. How do I get out of Management Mode? * To get out of Management Mode, simply unplug the power cord from the back or router for ten (10) seconds and plug the power cord back in (without using the Reset button). If the router's firmware is complete and without error, the router will start up normally. If the above does not work, try: * Download a local copy of WRT54G Version 5 firmware that you can use for recovery. Visit http://www.linksys.com/download to download the latest firmware. After unzipping and extracting the firmware file, click on the Browse button from the Management Mode page, select the firmware file, and upgrade the firmware. After this, Reset the router normally (by holding in the Reset button for 10 seconds) and the router should exit Management Mode. How do I enter Management Mode manually to recover my router? NOTES: * The PC that will be used for the recovery MUST be connected to the router via a hardwired Ethernet cable and not a wirelessly connected computer. * Be sure that you have a local copy of WRT54G Version 5 firmware that you can use for recovery. Visit http://www.linksys.com/download to download the latest firmware. * In most cases, the router will be able to provide an IP address via DHCP when in Management Mode. If your PC does not automatically receive an IP address from the router, you will have to set up a static IP address for the upgrade. See Answer ID 534 for more information. * When the router is forced into Management Mode, the Power light will blink. 1. Unplug the power cord from the back of the router. 2. Hold down the Reset button. 3. While holding down the Reset button, plug back in the power cord to the router. 4. Continue to hold the Reset button for five (5) seconds. After five (5) seconds, release the button. 5. Wait for about one (1) minute. Then, on a computer connected to the router, launch a web browser (for example, Internet Explorer or Mozilla Firefox). 6. Type in the router's IP address of http://192.168.1.1 into the Address field and press the [Enter] key. 7. The Management Mode - Firmware Upgrade interface should appear. NOTE: If you accidentally enter into Management Mode, you can exit by simply unplugging the power cord from the router and by plugging it back in. 8. Click Browse and locate the firmware file. 9. Click Apply to start the firmware upgrade process. 10.Once the firmware upgrade process has successfully completed, an "Upgrade Success" message will appear to confirm that the upgrade has ended. 11. Unplug the power cord from the back of the router and plug it back in -- this will restart your router using the new firmware.

Access the router's web-based setup page by opening a web browser. On the Address bar, enter your router's local IP address then press [Enter].
NOTE: The default IP Address of Linksys routers is "192.168.1.1". For instructions on accessing the web-based setup page using a Mac computer, click here.
When the login prompt appears, enter your router's Username and Password.
NOTE: The default password is "admin" and
the Username field is left blank. If you have set a password before
but forgot it, you need to reset the device. For instructions on how to
reset a Linksys router, click here.
On the Setup page, click the Wireless > Wireless Security.
NOTE: If some of the tabs are missing in the web-based setup page, upgrade the firmware of your router. For instructions, click here. You can also set the wireless security of your Linksys E-Series routers with Cisco Connect. To learn how, click here.
On the Wireless Security sub-tab, there are various wireless security options that you can choose from.
However, as mentioned earlier, the three most commonly used security modes are WEP, WPA Personal (or WPA Pre-Shared Key), and WPA2 Personal. The instructions below will show you how to set up the following security modes. On the other hand, the WPA2/WPA Enterprise Mixed Mode, WPA Enterprise, WPA2 Enterprise, and RADIUS security modes will only work if the router is connected to a RADIUS server.
Setting-Up the Wireless Security
WEP can be a 64-bit key with 10 hexadecimal digits or a 128-bit key with 26
hexadecimal digits. This encryption will prevent other users from
connecting to your wireless network. It will also protect your wireless
transmissions from being accessed by other users.
NOTE: In case the screen on your router's web-based setup page looks different, click here.
On Security Mode, select WEP.
Under WEP Encryption, select 40 / 64-bit (10 hex digits) and enter a unique word in the Passphrase field.
NOTE: The 128-bit key uses a higher
level of encryption compared to the 64 bit WEP. It uses a 104 bit (26
Click the Generate button and copy the string of letters and numbers displayed in the space provided for Key 1. The Key 1 contains the wireless password.
NOTE: You can also create your own Wireless Password (Key 1) given that it is in hexadecimal format. The hexadecimal system consists of the characters 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E, and F. You can only choose 10 characters (in any given order) from that set.
Wi-Fi Protected Access (WPA) is a
Wi-Fi standard designed to improve the security features of WEP. WPA is
stronger than WEP encryption. PSK and PSK2, the two types of WPA, give
you a choice between two encryption methods: the Temporal Key Integrity Protocol (TKIP), which incorporates Message Integrity Code (MIC) to provide protection against hackers, and Advanced Encryption System (AES), which utilizes a symmetric 128-Bit block data encryption.
NOTE: For older versions of Linksys routers, WPA Personal is also referred to as WPA Pre-Shared Key. Refer to the image below for an example.
To set up WPA Personal on a Linksys router, follow the steps below:
On Security Mode, select WPA Personal.
NOTE: If you are unable to find the WPA Personal or WPA2 Personal in
the list of choices for the Security Mode then you might need to
upgrade the firmware of your router to its latest version. Upgrading
the firmware can fix the bugs of the previous version and update its
Enter your Passphrase.
NOTE: The Passphrase must consist of at least eight characters and is case-sensitive.
