Some customers report issues connecting the DataHub to Starlink. Typically, this is due to Wi-Fi interference and may occur in port.
The best way to connect Starlink to the DataHub is via Ethernet, which you can read more about in Connect your Starlink to the DataHub.
In case this is not possible on your boat, please try these other troubleshooting steps which we have found to resolve DataHub and Starlink Wi-Fi connectivity issues for other customers:
1. Split Starlink Wi-Fi into 2.4 GHz and 5 GHz Networks
If your DataHub has poor Wi-Fi speed (less than 60 - 70 Mbs) while connecting to Starlink or frequently disconnects from Starlink Wi-Fi, you can split the Wi-Fi in the Starlink router so it has 2.4 GHz and 5 GHz Wi-Fi as a separate Wi-Fi name to connect to. This is more robust, and the DataHub will connect to the Starlink 2.4 GHz network.
Please take a look at the article below about selecting to split networks using the Starlink app before you connect the DataHub to Starlink Wi-Fi. The DataHub will only see the 2.4 GHz Wi-Fi of the Starlink router:
Important Note: The Starlink Mini does not have an option in the Starlink app to split Wi-Fi networks.
2. Check for Wi-Fi Interference
Another option to fix DataHub and Starlink Wi-Fi connection issues is to check the Wi-Fi channels for interference:
Please check that all the Networks are NOT on the same Channel.
If multiple Wi-Fi Networks are on the same Channel on your boat or nearby, there will be collisions on the network, and the connection will be unreliable.
If this is the case, you must change the Wi-Fi Channel of the other devices onboard your boat, such as the Iridium GO!, GO exec, Peplink, or Raymarine MFD.
Please have a look at the manuals of your other devices for instructions on changing the channel, or see the articles below:
3. Try repositioning your DataHub or connect your Starlink via Ethernet to the DataHub
In case you are still unable to achieve a reliable connection between the DataHub and Starlink over Wi-Fi:
Try repositioning your DataHub flat-mounted or closer to the Starlink Wi-Fi router. Flat mounting the DataHub will improve the strength and reach of its internal Wi-Fi antenna.
As mentioned above, connect your Starlink Router to the DataHub using an Ethernet cable to the Datahub WAN port.
4. Try configuring a Static IP address on the DataHub for connecting to Starlink.
Sometimes, Starlink does not assign an IP address to the DataHub, so it may help to set one manually. For more information, see How to set a fixed DataHub WAN/WWAN IP Address.
5. Try activating the SwapWiFi profile DataHub Profile
If you have tried all of the above and your DataHub still cannot maintain a reliable 2.4 GHz connection to Starlink, an alternative with Starlink split networks is to switch the DataHub Wi-Fi used for tethering from 2.4 GHz to 5 GHz.
A customer has reported success with this approach, so it is worth a try. For more, see DataHub how to use Profiles > Swap WiFi.
