Hi @ipsych, The Tobii T120 is part of the Tobii Pro business department.
This forum is intended for support with the Tobii EyeX and C4 Eye Tracker and associated SDK’s.
Please get in touch with Tobii Pro Support department directly @ http://www.tobiipro.com/contact/contact-support/ for an
answer to your query.
That being said, my first instinct with relation to your problem is to flash the firmware using the latest version which you can obtain through Tobii Pro support (the files are no longer online I’m afraid as T120 is deprecated hardware) .. Might also be a good idea to check your firewall and/or antivirus settings. Try disabling these applications temporarily to test if it may be responsible. Try also switching the network cable and if you are using the USB2LAN adapter, ensure latest drivers for this device are installed.
