Issues connecting the DataHub Pro to Starlink. Typically, this is due to Wi-Fi interference and may occur in port.
The best way to connect Starlink to the DataHub Pro is via Ethernet cable, which you can read more about in Connect your Starlink to the DataHub Pro.
In case this is not possible on your boat, please try these other troubleshooting steps which we have found to resolve DataHub Pro 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 Pro 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 Pro 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 Pro to Starlink Wi-Fi. The DataHub Pro 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 Pro 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 Pro or connect your Starlink via Ethernet to the DataHub Pro
In case you are still unable to achieve a reliable connection between the DataHub Pro and Starlink over Wi-Fi:
Try repositioning your DataHub Pro flat-mounted or closer to the Starlink Wi-Fi router. Flat mounting the DataHub Pro will improve the strength and reach of its internal Wi-Fi antenna.
As mentioned above connect your Starlink Router to the DataHub Pro using an Ethernet cable to the DataHub Pro WAN port.
4. Try configuring a Static IP address on the DataHub Pro for connecting to Starlink.
Sometimes, Starlink does not assign an IP address to the DataHub Pro, so it may help to set one manually. For more information, see How to set a fixed DataHub Pro WAN/WWAN IP Address.
5. Try activating the SwapWiFi profile DataHub Pro Profile
If you have tried all of the above and your DataHub Pro still cannot maintain a reliable 2.4 GHz connection to Starlink, an alternative with Starlink split networks is to switch the DataHub Pro 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 Pro how to use Profiles > Swap WiFi.
