On most Tobii Dynavox products is a software called Update Notifier installed that helps you to keep your system up to date. Should Update Notifier not be able to search for updates but instead show you the error message "Could not connect to the update server. Please check...." then it might be that your computer cannot access the Tobii Dynavox Update Service. Try to open this website http://updateservice.tobii.org with a regular internet browser. If it is loading the page and you can see a table with software products, your internet connection is ok. If you cannot see it, make sure both your computer and network firewall allows traffic to http://updateservice.tobii.org. It is regular http traffic, no ports are required.
