Make sure you use a router that is designed for unattended setups. Do not use low-cost consumer-grade routers intended for
business or leisure travel. A more expensive professional router will quickly pay for itself, and you won't have wasted journeys
simply to perform a reset. Examples of such professional routers are the
range from
Pepwave.

Note that the Cerbo GX does not support USB 3G/4G dongles, other than the
from Victron.
6.5. USB tethering using a mobile phone
This is a useful facility when it works - but don't rely on it because it has not proved very dependable. Consult the internet for
instructions about tethering for your phone and its particular operating system. We have heard of it working on:
• Samsung Galaxy S4
...but not on:
• iPhone 5s with iOS 8.1.1
6.6. Manual IP configuration
Almost no installations will need the IP address configuration to be inserted manually as most systems support automatic IP
configuration (DHCP) - and that is also the Cerbo GX default setting. If you do need to configure the address manually, select the
following template:
Complete details of IP requirements, as well as used port numbers will be found in the
the [131] Cerbo
GX.
6.7. Multiple connections (failover)
It is possible to connect the Cerbo GX to multiple networks simultaneously, Ethernet, WiFi and LTE (via a GX LTE 4G). In this
case, the GX device uses Ethernet or WiFi whenever available and falls back to LTE if the Ethernet connection is lost and WiFi
access isn't available.
The priority of which connection the GX device uses is based on the following order:
1. Ethernet, regardless of whether there is a WiFi or LTE connection.
2. WiFi when there is no Ethernet connection and regardless of whether there is an LTE connection.
3. LTE when there is no Ethernet and WiFi connection.
Please note that the GX device does not check whether any network devices mentioned have an active
internet connection. This mechanism only considers the active network connection.
6.8. Minimise internet traffic
In situations where internet traffic is expensive, for example a satellite uplink or with roaming GSM/cellular charges, you may want
to minimise the internet traffic. The steps to take are:
• Disable
auto firmware updates [62]
• Do not enable
remote support [132]
• Reduce the Log interval (Settings → VRM online portal → Log interval) to a very low frequency. Note that state changes
(charging → inverting, or bulk → float) and also alarms will cause extra messages to be sent
