Can I Upgrade My Wireless Routers Firmware From a Wireless Computer?

Wireless routers utilize firmware to provide functionality.

The firmware on a wireless router is somewhat like its operating system. Without this firmware, the router is not able to function as needed. Firmware is actually software stored electronically in ROM (read only memory), similar to the BIOS on a computer. Firmware upgrades usually enhance the pre-existing features of a wireless router and often times improve performance issues such as dropped connections.

Function

The firmware on a wireless router handles the flow of data and allows the router to maintain its functionality such as sending and receiving data. On most routers, entering in the IP address of the router (often times the default gateway, found in Windows by using the "ipconfig" command) into a web browser will allow the router's built in configuration utility to be accessed. This utility is provided by the routers firmware.

Method

Updating the firmware on a wireless router is usually accomplished by downloading a binary package (such as a .exe file on Windows). Running the binary package allows you to set up the firmware upgrade. Most manufacturers provide free updates to their firmware at their official website.

Considerations

Because firmware is a hybrid of software and hardware, stored on ROM in most cases, taking time to prepare for the upgrade is essential. If the firmware update does not complete, the router will no longer function. It is best to always perform firmware upgrades using an Ethernet Cable rather than via a wireless connection. Because the router needs to be able to communicate with the computer during the upgrade process, if the wireless connection is dropped the lack of an Ethernet connection could result in a non-working router.
