Updating your Netgear router’s firmware can fix bugs, add features that are not in the firmware’s current version and increase the general performance of the device. You can check to see if there is a new version of the firmware -- and install it -- through the Firmware Upgrade section of the router’s Web Administration Interface. You need to connect your computer directly to the router with an Ethernet cable to perform the update, because performing a wireless network update may corrupt the new firmware.

Step 1

Connect your computer directly to the Netgear router with an Ethernet cable. Insert one end of the cable into an empty LAN port on the router and the other into the Ethernet port on your computer.

Step 2

Open a Web browser, and then enter the router's IP address in the browser's address bar. The router’s default IP address -- for example, “192.168.1.1” -- is usually printed on a sticker located on the back or bottom of your Netgear router. You can also find the IP address by referring to the router’s documentation or navigating to the Support section of the Netgear website (see link in Resources).

Step 3

Press the "Enter" key. Enter “Admin” in the Username box, and “Password” in the Password box -- which are the default login credentials for most Netgear routers. Again, you can find your router’s default login credentials by referring to the device’s documentation, navigating to the Support section of the Netgear website or checking the sticker on the back or bottom of the device. Click the "OK" button to open the Netgear Genie Web Administration Interface.

Step 4

Select the "Advanced" tab, and then click "Administration."

Step 5

Select "Firmware Upgrade" from the Administration menu to open the Firmware Upgrade page.

Step 6

Click "Check," and then wait for the router to detect the new firmware and display the Firmware Upgrade Assistant.

Step 7

Click "Yes" to update the router's firmware.
