Setup and Installation

Proper installation of the Intel Dual Band Wireless-AC 8260 adapter is crucial for optimal performance. Follow these steps carefully:

1. Prepare Drivers: Before beginning the physical installation, visit the official Intel website to download the latest Wi-Fi and Bluetooth driver packages for the 8260 adapter. Save these to an accessible location on your computer.
2. Uninstall Old Drivers (if applicable): If you are replacing an existing wireless adapter, go to "Programs and Features" in your Control Panel and uninstall any old wireless or Bluetooth applications (e.g., Broadcom WIDCOMM).
3. Disable Old Adapter: Open Device Manager (right-click on "This PC" or "My Computer" and select "Manage" then "Device Manager"). Locate your old Wi-Fi adapter under "Network adapters" and Bluetooth adapter under "Bluetooth". Right-click and select "Disable device" for both, then "Uninstall device" (do not check the box to delete driver software).
4. Power Off and Disconnect: Shut down your computer completely and disconnect it from all power sources. For laptops, remove the battery if possible.
5. Open Computer Case: Carefully open your computer's case or laptop's back panel to access the M.2 slot where the Wi-Fi adapter will be installed. Refer to your computer's service manual for specific instructions on opening the case.
6. Remove Old Adapter (if applicable): If replacing an old adapter, unscrew the retaining screw, carefully disconnect the antenna wires (usually black and white), and gently pull the old card out of the M.2 slot.
7. Install New Adapter: Insert the Intel Dual Band Wireless-AC 8260 adapter into the M.2 slot at an angle, then press it down and secure it with the retaining screw.
8. Connect Antenna Wires: Carefully reattach the antenna wires to the corresponding connectors on the new adapter. Typically, the black wire connects to the main (1) connector and the white wire to the auxiliary (2) connector, but verify markings on the card. They should snap into place.
9. Close Computer Case: Reassemble your computer, ensuring all panels are securely closed and screws are tightened.
10. Power On and Install Drivers: Power on your computer. Windows 10 should recognize the new hardware. Navigate to the downloaded driver packages and install the Wi-Fi drivers first, followed by the Bluetooth drivers.
11. Reboot: Reboot your computer to finalize the installation.

Troubleshooting

If you encounter issues with your Intel Dual Band Wireless-AC 8260 adapter, try the following solutions:

• No Wi-Fi or Bluetooth after Installation:
  • Verify that the adapter is correctly seated in the M.2 slot and the retaining screw is secure.
  • Ensure antenna wires are properly connected to the adapter.
  • Check Device Manager: Look for "Intel(R) Dual Band Wireless-AC 8260" under "Network adapters" and "Intel(R) Wireless Bluetooth(R)" under "Bluetooth". If there are yellow exclamation marks, reinstall the drivers.
  • Ensure no old drivers are conflicting. Completely uninstall any previous wireless or Bluetooth drivers.
• Intermittent Connection or Slow Speeds:
  • Update your Wi-Fi and Bluetooth drivers to the latest version from Intel's website.
  • Ensure your router firmware is up to date.
  • Try moving closer to your Wi-Fi router or reducing interference from other electronic devices.
  • Check for physical obstructions or damage to the antenna wires.
• Bluetooth Devices Not Pairing:
  • Ensure the Bluetooth device is in pairing mode.
  • Remove and re-add the Bluetooth device in your computer's Bluetooth settings.
  • Restart the Bluetooth service in Windows Services (services.msc).
  • Update Bluetooth drivers.
• "Non-broadcast network" connection issues (especially after switching networks):
