How to update the firmware:

- Connect the AirStation to the same network as your PC. For best results, connect the AirStation directly to your PC with an Ethernet cable.
- Boot your PC.
- Confirm that the PC's and the AirStation's IP addresses are on the same network subnet. Refer to AirStation's user manual to confirm how to change IP address settings.
- Open a browser and enter "192.168.11.1" in the URL field, then press the enter key.
- Enter "admin" for the username and "password" for the password. Note: If you changed the password, enter the password that you configured.
- Click "Update AirStation Firmware" at the left of the screen.
- Click "Browse" to the right of "Firmware File" and navigate to the firmware file.
- When the update starts, the power LED will blink red. It will take about 6 minutes to finish updating. When it finishes, the power LED will blink green or turn off. Do not disconnect power to the unit while the power LED is blinking red or your AirStation may be damaged.
- To confirm that your firmware is successfully updated, check the version number.

About Router Firmware:

Before you consider downloading this firmware, go to the system information page of the router and make sure that the currently installed version isn’t either newer or matching this release.

Due to the large variety of router models and different methods for upgrading the device, it is highly recommended that you read and, above all, understand the installation steps before you apply the new firmware, even if you are a power user.

In theory, these steps shouldn’t be much of a hassle for anyone, because manufacturers try to make them as easy as possible, even if they don’t always succeed. Basically, you must upload the new firmware to the router through its administration page and allow it to upgrade.

If you install a new version, you can expect increased security levels, different vulnerability issues to be resolved, improved overall performance and transfer speeds, enhanced compatibility with other devices, added support for newly developed technologies, as well as several other changes.

If you’re looking for certain safety measures, remember that it would be best if you perform the upload using an Ethernet cable rather than a wireless connection, which can be interrupted easily. Also, make sure you don’t power off the router or use its buttons during the installation, if you wish avoid any malfunctions.

If this firmware meets your current needs, get the desired version and apply it to your router unit; if not, check with our website as often as possible so that you don’t miss the update that will improve your device.
