Netgear WNDR4300 – N750 Wireless Dual Band Gigabit Router 사용자 설명서

The router firmware (routing software) is stored in flash memory. You can update the 
firmware from the Administration menu on the Advanced tab. You might see a message at 
the top of the genie screens when new firmware is available for your product.

You can use the Check button on the Router Upgrade screen to check and update to the 
latest firmware for your product if new firmware is available. 



Select Advanced > Administration > Firmware Upgrade to display the following 

screen: 

Click Check.

If new firmware is available, the router finds it.

Click Yes to update and locate the firmware you downloaded (the file ends in .img). 

When uploading firmware to the router, do not interrupt the web 
browser by closing the window, clicking a link, or loading a new 
page. If the browser is interrupted, it could corrupt the firmware.

When the upload is complete, your router restarts. The upgrade process typically takes 
about 1 minute. Read the new firmware release notes to determine whether you need to 
reconfigure the router after upgrading.
