For installations where more devices require an internet connection, as is often the case on a yacht or RV/caravan, or where a reliable failover/backup solution is necessary, please consider installing a mobile router instead.
A mobile router can share cellular data with multiple devices such as smartphones, tablets, laptops and other devices via its Ethernet port or Wi-Fi, and is able to switch to a previously configured Wi-Fi connection in the event of an Ethernet connection failure or vice versa.
