Note: Please note you can locate the existing router firmware version at the upper right location of router management page.
So you have a wireless router that has been quietly serving Wi-Fi to your household for many years? Chances are, if you answered yes to either question, you may not have upgraded your router’s firmware in quite some time.
Your router’s firmware is basically the operating system that is specifically designed to run on your specific make and model of router (unless you are using a multi-router compatible open source firmware such as DD-WRT).
If you have a different router, find your solution here to replace the factory default firmware with DD-WRT.
Leave your router's installation CD in the box, you won't need it. Connect your PC to the LAN of your hotspot router (do not connect it to the internet port, because you have to connect your existing netowork to the internet port). Browse to the MINI firware which you have previously downloaded, then press UPGRADE.
Be sure your computer obtains IP addresses automatically from your existing router or network via DHCP. Open a browser and type (login: admin, passwd: admin) 3. (In case of upgrading the original Linksys firmware, you MUST upgrade to the mini version of DD-WRT first). After the successful firmware upgrade, reset your router by pressing the reset button for at least 5 sec.
UPGRADE MUST NOT BE INTERRUPTED so please don't turn off the power or press the reset button. on the back of your router (little button on the back of the router).
Security Features and Fixes One good reason why your router manufacturer may put out a firmware update is because they are trying to fix a vulnerability that was detected in the current firmware, updated firmware is similar to system updates (as in Microsoft’s Windows Update).
