If no LAN or WLAN is available at your location, you can establish a UMTS connection with the Huawei E3531 HSPA+ surf stick.

Ensure that data traffic is adequately secured. You can do this in the following ways:
  • Use a private APN.
  • Use OpenVPN and block traffic that would circumvent VPN with firewall rules.

If the surf stick is already inserted and has been configured, the network connection will be established within approx. 35 seconds after the thin client boots. The network connection will remain in place until the surf stick is removed or the thin client is put on standby or shut down.

Symbols in the system tray indicate the status of the network connection:

  • The network connection is established; the thin client is online
  • The network connection was interrupted; the thin client is offline
