The backup communication setup works well when Spider is set up to be the TCP/IP client and the receiver
is set up as the TCP/IP server. Connections to Spider as the TCP/IP server may not work when switching
back from the backup communication to the primary.

How to use residential gateway
Background information
The Residential gateway functionality can be used to connect a device without internet access through the receiver to the internet. It
uses the receiver's internet connection to establish this setup.
The receiver is connected to the internet via the WAN interface (e.g. Mobile internet, Ethernet or WLAN).
The external device is connected to the receiver via the LAN interface (e.g. Ethernet or WLAN). The receiver therefore acts as an
access point. Both, the receiver and the attached device then share the internet connection of the receiver.
The configuration of one possible use case is described in detail below.
Before you begin
Below step-by-step guide will guide you through a setup using mobile internet as the WAN interface to connect to the internet and
Ethernet as the LAN interface that has a laptop connected and allows this laptop to share the internet access.
If the mobile internet device is used as WAN interface, it is highly recommended to use an extension cable
for the GPRS/UMTS antenna. This will ensure that the signal reception of the mobile network is stable and
reliable.
If the residential gateway is in use, it is recommended to monitor the CPU load of the GR receiver as
available in the web interface on page Status > System Status. The CPU load mainly depends on the
general receiver configuration but is also affected by the network traffic. If the CPU load is constantly higher
than 80%, some functionality should be disabled.
