The issue you are experiencing with your Surface Hub 2S failing to reconnect to Wi-Fi after standby or screen-off cycles may be related to power management settings of the Wi-Fi adapter or the behavior of the modern standby feature in Windows 11 IoT.
Here are some troubleshooting steps and considerations:
- Wi-Fi Power Management: Ensure that the Wi-Fi adapter's power management settings are configured to allow it to wake up and reconnect automatically. You can check this in the Device Manager:
- Open Device Manager.
- Expand Network adapters.
- Right-click on your Wi-Fi adapter (Intel Wireless-AC 9260) and select Properties.
- Go to the Power Management tab and ensure that "Allow the computer to turn off this device to save power" is unchecked.
- Modern Standby Behavior: Windows 11 IoT supports modern standby, which allows devices to maintain network connectivity while in a low-power state. If the Wi-Fi connection is lost during standby, it may be due to the device not properly transitioning to the low-power state. You might want to verify if the device firmware is up to date and if there are any known issues with the current version.
- Driver Updates: Ensure that the Wi-Fi driver is the latest version. Sometimes, updating to the latest driver can resolve connectivity issues.
- Network Settings: Check if there are any specific network settings or configurations that might be causing the issue. For example, adjusting roaming aggressiveness or ensuring that the device is not set to connect only to a specific band (2.4 GHz or 5 GHz) can help.
- Environmental Factors: Consider the environment where the Surface Hub is located. Interference from other devices or physical obstructions can affect connectivity. Ensure that the device is in an area with good Wi-Fi coverage.
If these steps do not resolve the issue, you may want to consult with Microsoft support for more tailored assistance regarding your specific setup and firmware version.
