Cisco Linksys Router: How to Upgrade the Firmware

network router

Keeping your router’s firmware up-to-date is important for security and performance. Here’s how to upgrade a Cisco Linksys router.

Updating the router’s firmware on your home network is often overlooked. Upgrading the firmware improves performance, stability, and wireless range.

Because Cisco Linksys is the most common home router, this article shows the process on a Cisco E4200 wireless router. Remember, each router is different, but upgrading the firmware is essentially the same process.

Important: Make sure you’ve got a hardwired connection to the router before attempting to upgrade the firmware.

Update Cisco Linksys Router Firmware

Open your browser and type in the router’s IP Address – typically into the address bar. Hit Enter.
Enter Router IP

Next, type in the router username and password. You do have your router password-protected.


Now that you’re logged into the router view the firmware version currently on the router. In my example, it’s 1.0.02.

Old Version

Visit the Cisco Linksys support site and select your router’s model to see an updated version.

If there is a new version, download it to a convenient location on your system. On your router, go to Administration >> Firmware Upgrade.

Firmware Upgrade

Browse to the location of the latest drive you just downloaded. Click Start Upgrade.

Start Upgrade

Now, wait while the firmware is upgraded. Make sure not to do anything else on your computer while the process is active.

Firmware Progress

Then wait while the router reboots. You won’t be able to access the Internet or network while it’s rebooting. Click Continue.

Router Reboot

Success. The router now has the latest firmware version.

New Firmware Version

Every Linksys router I’ve seen in my career upgrades the same way. Keeping the router up-to-date is just as important as keeping your PC’s hardware and software current.
