How do I upgrade a Firmware?

Wireless routers contain built-in programmable logic called firmware. The firmware is embedded software that implements network and security protocols for that specific model of hardware device.Every wireless router ships with a tested version of firmware provided by the manufacturer. However, most routers are also designed to support a firmware upgrade process. This allows the manufacturer to provide enhancements to routers already sold. Manufacturers generally provide firmware upgrades as free downloads from their Web site.

Additionally, a few manufacturers (like Linksys) provide their firmware as open source code on the Internet. Programmers worldwide are free to modify and extend the code with new features for their routers. Several versions of this hacked firmware can be found on the Web, but the average homeowner should avoid these types of firmware.
The Firmware Update Process
You begin a firmware upgrade by downloading a binary file package from the manufacturer's Web site. After the package is set up properly on a PC, an administrator can launch the actual upgrade from the wireless router's administrative console. The router will stop functioning if the upgrade fails to complete. For this reason, manufacturers generally recommend an Ethernet cable be run from the router to the PC to ensure maximum stability during the update. Consult the router's product documentation for details.
Immediately after purchasing a router, check the firmware version to ensure it is the latest version. Firmware can be installed on a router at the factory several months before the router is sold.
Then, check the manufacturer's Web site occasionally over time for any new firmware upgrade postings. Each time a firmware upgrade is posted, the manufacturer will provide notes detailing the enhancements it provides. Feel free to skip an upgrade if the new version does not offer any interesting features. However, if a router is performing sluggishly, freezing unexpectedly or experiencing dropped connections, firmware upgrade often supplies a quick fix.

Firmware upgrade is a simple but a delicate procedure. Make sure you are loading the correct firmware. You should get your firmware from the website of your router. Installing a THIRD PARTY firmware to your router voids the warranty of your router. Here is a tip for a successful firmware upgrade. BEFORE FIRMWARE UPGRADE(push the reset button of the router for 30 seconds then unplug the power of the router for 10 seconds). Upgrade the firmware. After the upgrade push the reset button again for 30seconds, unplug power for 10 seconds.

Firmware Upgrade Instructions:
Please download and unzip the firmware file to computer's local hard drive and then follow the instructions in the "readme.txt" file to upgrade the firmware.

Warning : -
Firmware upgrade failure may permanently damage the unit and causing it not to function. If the issues in the "Release Note" do not address the problem you are experiencing, please do not upgrade the firmware. Never upgrade the firmware using a wireless connection. Firmware upgrade will reset the Router to factory default state (all current settings will be replaced by default settings). When necessary, please write down the Router's current settings before performing the firmware upgrade. Please do not load the previously saved Router "configuration file" to the new firmware.
