Define Internet Connections
If your network service provider charges you on a pay-as-you-use basis, you may want to change the Wi-
Fi and mobile data settings to reduce your data costs. You can use different settings for roaming and at
home.
Important:
Use encryption to increase the security of your Wi-Fi connection. Using encryption reduces the risk of
