Firmware updates are regularly posted on the Cisco website. These updates may include bug fixes and functionality
enhancements to the router. If you are experiencing problems with your router, you may upgrade or re-flash the
firmware to fix them.

strongly recommended that you use a wired computer when upgrading the router’s firmware.
It is also important for you to determine the model number of your router to identify which set of instructions will be

Checking the firmware version of your router
Step 1:
Access the router’s web-based setup page. To do this, launch a web browser such as Internet Explorer or
Safari. Enter your router’s IP Address on the address bar, then press [Enter]. When the login prompt
appears, enter your router’s User name and Password.
NOTE: The default IP Address of Linksys routers is “192.168.1.1”. For instructions on how to check the IP
address of your router, click here.
IMPORTANT: The default User name and Password is “admin” but if you have used Cisco Connect to set
up your router, you may have to open the software to retrieve them. To retrieve your router User name and
Password through Cisco Connect, go to Router Settings > Advanced Settings.
Step 2:
On the router’s Setup page, check the upper right corner of the screen for the firmware version.
Downloading the firmware
Step 1:
Go to the Cisco HomeSupport page.
Step 2:
In the Search Support box, enter the model number of your router then press [Enter]. For instructions on
getting your router’s model number, click here.
NOTE: In this example, we used the E4200.
Step 3:
Once the page opens, click the Downloads tab.
Step 4:
Click the drop-down arrow and select the correct version of your router. To learn how to check the hardware
version, click here.
Step 5:
Click Download under Firmware to download the latest firmware of your router.
NOTE: If the current firmware version of your router matches the one found online, upgrading is not
necessary.
Step 6:
Click Save in the File Download dialog box that appears, choose an accessible directory such as the
Desktop and click Save. Once the download is complete, click Close, if prompted.
NOTE: Image may vary depending on the operating system of your computer.
If you're using a Mac computer, click Download in the dialogue box that appears. When the download has
been completed, click the red button to close the window.
The name of the file may vary depending on the firmware file of your router.
Taking note of your current settings
After upgrading the router’s firmware, a reset needs to be done which will require you to reconfigure your settings
from scratch. Be sure to note down important settings before resetting the router and use it as basis for reconfiguring
the router later.
NOTE: You can use the back-up and restore configuration feature of your router before resetting so as not to go
through the whole process of reconfiguration. However, firmware upgrades sometimes include added functionalities
which might mess up the settings once restored from a backup. In case this happens, you might have to manually
reconfigure the router.
Performing the Upgrade
Step 1:
Access the router’s web-based setup page.
Step 2:
Click the Administration tab.
