You can update your NETGEAR Nighthawk M6 (MR6110) with a computer by using its web management page. This is the most common and recommended method, as the hotspot checks directly with your carrier (like AT&T) for the latest firmware.

Here are the step-by-step instructions.

MPU: How to Update Your Hotspot's Firmware

The easiest way to update is by using the built-in "Check for Updates" feature in the router's settings.

 * Connect Your Computer: Connect your computer to the Nighthawk M6's Wi-Fi network.

 * Open a Web Browser: On your connected computer, open a web browser (like Chrome, Firefox, or Safari).

 * Go to the Admin Page: In the browser's address bar, type http://mywebui.net or http://attwifimanager and press Enter.

 * Log In: You will be prompted to enter your administrator password. This is the password you created when you first set up the hotspot. (If you never changed it, the default password might be attadmin).

 * Navigate to Settings: Once logged in, look for a SETTINGS option, usually at the top of the page.

 * Find Firmware Update: In the Settings menu, go to Administration > Firmware Update.

 * Check for Updates: Click the Check for Updates button. The device will then connect to the server to see if a new firmware version is available.

 * Install the Update: If an update is found, the page will show you the new version details. Follow the on-screen prompts to download and install the update.

> Important: Do not turn off, unplug, or disconnect from the hotspot while the update is in progress. Interrupting the update can damage the device. The hotspot will restart automatically once the update is complete.

A Note on "Manual" Updates

While many routers allow you to manually download a firmware file and upload it, this is not common for mobile hotspots like the M6.

 * Carrier-Controlled: Firmware updates for mobile hotspots are typically managed and released by the mobile carrier (e.g., AT&T, T-Mobile).

 * No Public Files: Because of this, NETGEAR does not usually post firmware files for the MR6110 on their public download center.

The "Check for Updates" method described above is the official and, in most cases, the only way to update your device.
