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).
Important: Make sure you’ve got a hardwired connection to the router before attempting to upgrade the firmware. If there is a new version, download it to a convenient location on your system. Browse to the location of the latest drive you just downloaded.
Open your browser and type in the router’s IP Address – typically 192.168.1.1 into the address bar.
Most routers have a built-in update checker, which may or may not perform the entire process automatically.
If you're using an Apple Air Port router, you can use the Air Port Utility program to check for updates.
Some routers may require that you first save the file to your computer and then select the firmware file via the administration console.
Remember each router is different, but upgrading the firmware is essentially the same process. Now that you’re logged into the router, view the firmware version currently on the router. Visit the Cisco Linksys support site and select you router’s model to see if there is an updated version. Make sure not to do anything else on your computer while the process is active. You won’t be able to access the Internet or network while it’s rebooting. Updating the router’s firmware on your home network is often overlooked.Upgrading the firmware improves performance, stability and wireless range. Every Linksys router I’ve seen in my career upgrades the same way.Cisco, the manufacturer of Linksys routers, provides periodic firmware updates for all products covered under the terms of support.Check for updates regularly to ensure optimum functionality of a Linksys router and avoid certain bugs, intermittent wireless connections or other issues related to network connections.Router manufacturers may also issue a firmware update to upgrade features such as outdated encryption modules or they might add entirely new security mechanisms that weren’t in previous versions of the firmware.
