A few people using Windows 10 started getting an error when connecting their PlayBook via WiFi. The error was the SMB1 not enabled. Getting this enabled is quite easy.

Go to your Control Panel on your computer.

Click on Programs. Then under the larger menu of Programs and Features, select Turn Windows features on or off.

Windows Features will now pop up.

Click the checkbox next to SMB 1.0/CIFS File Sharing Support

Then hit OK. You will be prompted to restart your PC.

After restarting your PC you can now connect to your PlayBook via Wifi file sharing.
