Preparing for a Firmware Upgrade

Checking Current Firmware Version

Before upgrading, it’s essential to know the current firmware version installed on your router. This will help you determine if an upgrade is necessary and ensure compatibility with the new firmware.

1. Accessing the Router’s Web Interface:
   • Connect your computer to the router via Ethernet or Wi-Fi.
   • Open a web browser and enter 192.168.1.1 into the address bar to access the router’s login page.
2. Logging In:
   • Enter the router’s admin credentials. The default username and password are typically both admin, but these may have been changed.
3. Navigating to Firmware Information:
   • Once logged in, go to the Status tab or section where the current firmware version is displayed. Note down this version for reference.

Downloading the Latest Firmware

1. Finding the Latest Firmware:
   • Visit the Cisco Linksys support website. Search for the Cisco Linksys E1200 and navigate to the firmware download section.
2. Downloading the Firmware File:
   • Download the latest firmware version compatible with your Cisco Linksys E1200. Ensure that the firmware file matches your router model to avoid compatibility issues.

Backup Configuration Settings

Before performing a firmware upgrade, it’s crucial to back up your router’s current configuration settings. This ensures that you can restore your settings if anything goes wrong during the upgrade process.

1. Accessing Backup Settings:
   • Log in to the router’s web interface and navigate to the Administration tab.
2. Backing Up Settings:
   • Look for the Backup or Save/Restore Settings option. Follow the prompts to save your current configuration settings to a file on your computer.

Performing the Firmware Upgrade

Step-by-Step Upgrade Process

1. Accessing the Firmware Upgrade Section:
   • Log in to the router’s web interface and go to the Administration tab. Select Firmware Upgrade from the menu.
2. Uploading the New Firmware:
   • Click on the Browse or Choose File button to locate the downloaded firmware file on your computer. Select the file and click Upload.
3. Starting the Upgrade:
   • Confirm that you want to proceed with the firmware upgrade. The router will begin uploading and installing the new firmware. This process may take several minutes.
4. Avoiding Interruptions:
   • Do not turn off the router or disconnect it from the power source during the firmware upgrade process. Interruptions can cause the upgrade to fail and potentially render the router inoperable.
5. Restarting the Router:
   • Once the firmware upgrade is complete, the router will usually reboot automatically. If it does not, manually restart the router to complete the process.

Post-Upgrade Tasks

1. Verifying Firmware Version:
   • After the router has restarted, log back into the web interface and check the Status tab to verify that the new firmware version is installed.
2. Restoring Configuration Settings:

3. Testing the Router:
   • Test the router to ensure that it is functioning correctly. Check both wired and wireless connections, and verify that all network settings are working as expected.

Troubleshooting Common Issues

Firmware Upgrade Fails

1. File Compatibility:
   • Ensure that the firmware file you downloaded is specifically for the Cisco Linksys E1200. Using incorrect firmware can cause the upgrade to fail.
2. Router Reboot Issues:
   • If the router does not reboot after the upgrade, try manually restarting it. If the router fails to start up, you may need to perform a factory reset.
3. Incomplete Upload:
   • If the firmware upload process is interrupted, try uploading the file again. Ensure a stable internet connection and avoid power interruptions during the upgrade.

Connection Problems After Upgrade

1. Network Settings Reset:
   • Some firmware upgrades may reset network settings to default. Reconfigure your network settings, including wireless SSID and security options.
2. Wireless Issues:
   • If wireless connectivity issues arise, check that the wireless settings are correctly configured. Adjust settings such as channel width and security protocols as needed.

Restoring Factory Defaults

1. Performing a Factory Reset:
   • If you encounter persistent issues, consider performing a factory reset. Press and hold the reset button on the router for approximately 10 seconds until the power LED blinks. This will restore the router to its default settings.
2. Reconfiguring the Router:
