Hello Don,
Thank you for reaching out in the Microsoft Community! I can understand how frustrating it must be when your Surface Pro unexpectedly loses both internet and mouse connectivity, requiring a reboot to restore them. This can really interrupt your workflow, especially during important tasks. Could you share what troubleshooting steps you've taken? Also, which model/version of Surface Pro are you using? Such issues are often linked to outdated drivers, power-saving settings, or even device interference. A great first step is to check Device Manager for any alerts and update your Wi-Fi and mouse drivers. Additionally, consider disabling any power-saving features that might be shutting down your network adapter or USB ports to conserve energy.
If you're using a Bluetooth or USB mouse, try changing ports or temporarily using a wired mouse to eliminate hardware conflicts. Running the built-in network troubleshooter and resetting your network settings can also help resolve any underlying issues. And just to be cautious, ensure your Surface has the latest firmware and Windows updates installed.
