Overview
If you are having trouble 
accessing the web or establishing a 
VPN connection, your 
network settings might be the culprit. This mostly applies to Wi-Fi and 
LAN (Local Area Network) connections. However, 
corrupted settings can affect Ethernet, Bluetooth, and 
Cellular/LTE networks as well.
Before attempting to reset your network settings, we recommend restarting your router and/or your device. In most cases that will do the trick. If you are still unable to connect, resetting these settings to their default values will likely help you connect again.
