Upgrading the Linksys router’s firmware using the classic web-based setup page

Upgrading the Linksys router’s firmware using the classic web-based setup page is necessary if you want to improve the current performance of your device and fix the issues that the previous firmware version may have.  While you have the option to let your router automatically update its firmware, manual upgrade lets you manage the updates you want to load on your device.

NOTE:  The latest version of your device’s firmware is posted on its product page in the Linksys Support Site.  Check your device’s current firmware version to see if you need to upgrade it to the latest version posted in the support site.  You can see this information at the uppermost right portion of the router’s web-based setup page.

The steps below will guide you on how to properly perform manual firmware upgrade on your Linksys router.  If you want to watch the video, click here.
 
QUICK TIP:  If you have a Linksys Smart Wi-Fi Router, update its firmware through your Linksys Smart Wi-Fi Account.  For instructions on how to do this, click here.
 
IMPORTANT:  To prevent upgrade failures, the following items must be checked before proceeding with the upgrade process.
  • The computer you will use to do the upgrade should be connected to the router using an Ethernet cable for stable connectivity.  It is NOT recommended to update the firmware wirelessly as it may cause permanent damage to the router.
  • Use another browser if your default browser doesn’t work.  Alternatively, you can use another computer to perform the upgrade.
  • Download the correct firmware and version for your device.
  • If your router has a storage link and your storage device is connected to it, make sure to remove the storage device before upgrading the router’s firmware to prevent data loss.
  • Make sure that you have created a back-up configuration before removing the storage device.  For instructions on how to create a back up, click here.
To manually upgrade the firmware of your router, you need to complete the following steps:
 
i.  Checking the model and version of your router
ii.  Downloading the firmware
iii.  Performing the upgrade

 
Checking the model and version of your router

Flip the device over.  You should find the model number and the serial number on the sticker underneath the device.
  To learn how to find the model and serial number of your device, click here.

 
Downloading the firmware
 
Download and save the updated firmware file from the Linksys Support Site to your computer.  You can save it to your preferred destination folder (i.e. desktop, My Documents).  If you need more help in downloading the firmware, click here.
 
NOTE:   The firmware format is .bin, however, there are instances where the file may have a different extension such as .img and .bix.
 
Performing the upgrade
 
Step 1:
Access the router’s web-based setup page.  To learn how, click here.
 
IMPORTANT:  Make sure to enter the correct router IP address in accessing the router’s web-based setup page.  The default router IP address is 192.168.1.1.  If this address does not work, it might have been changed when the router was set up so you need to check the new IP address.  To learn how, click here.  If you still can't access the web-based setup page, try resetting the device.
 This will restore your router to factory defaults. For instructions, click here.


NOTE:  If you encounter a "502 Error" or Bad Gateway Error​, you can perform a manual firmware upgrade by bypassing Smart Setup to solve the issue. For instructions, click here.

Step 2:  
Click on Administration > Firmware Upgrade.

 
 

Step 3:
Click on the Browse… button.

 
 

Step 4:
Locate and select the file that you have downloaded then click Open.

 
 

NOTE:  If you are using Mac OS X®, click the Choose button.

Step 5:
Click the Start Upgrade button.

 
 

A warning prompt stating not to interrupt the upgrade will appear.
 
 

However, if you selected the incorrect file a prompt similar to the image below will appear.  If this happens, click the OK button and repeat Steps 2 to 4 and select the correct file.
 

Step 6:
Click Continue when it prompts you that the upgrade has been successful.

Step 7:
Powercycle the router by unplugging it from the power outlet for 10 seconds, then re-plug it.

Resetting and reconfiguring the router
 
Resetting and reconfiguring the router maybe required if you have lost your Internet connection after upgrading the firmware or if the connectivity issues you encountered prior to the update still exist.  This is when the backup file you saved earlier comes handy.

After resetting, click on any of the links below to learn how to set up your router according to the Internet connection type that you are using:

Cable Internet service
DSL Internet service
Static IP account
