Your Data Center is already running the latest firmware version, so no worries there. Version 1.0.25 is currently the latest available version.
Wi-Fi connection is not supported on the current version of the Data Center, so you can safely ignore that setting for now.
For the weak GPS signal warning, please make sure the Data Center is installed in a location with a clear view of the sky and at least 120° of unobstructed open space. Installing it at the highest practical location is recommended. You may also want to double-check that the RTK antenna is properly connected and installed. If you’ve already verified these points and are still seeing the weak GPS warning, please reach out to our Support Team for further assistance.
