If you replace the computer that is used to run tests, you will need to transfer the Geonet card (PCI or PCI-ex port) from your old computer to the new one for establishing network. Copy all your folders related to Geocomp equipment which includes software and template files.
Please then install the latest drivers on your computer. Please find the link below on how to do that.
Network & Drivers - I: Network Card and Driver Installation
Should you have any issues with the installation of the network card or drivers, please open a ticket by clicking "New Support Ticket".
