You may experience connectivity issues or performance issues when you connect a mobile PC that is running Windows to a wireless access point
You may experience random connectivity issues when you connect a Windows-based mobile PC to certain Wi-Fi "hot spots." These connectivity issues include the following:
Modify the default on-battery power setting for the wireless network adapter. Configure the wireless network adapter to use the Maximum Performance setting when Windows is configured to use the Balanced power plan or the Power saver power plan.
Note: See https://support.microsoft.com/en-us/help/928152/you-may-experience-connectivity-issues-or-performance-issues-when-you for operating system specific instructions
Method 3: Use the "High performance" power plan
If the computer is running on a power plan other than the High performance power plan when you connect to a wireless network, manually change the power plan to High performance.
