Hi @chrisscaefer,
Sorry to hear about your troubles. Indeed, the underlying reason for this disconnection issue has now been resolved in the Tobii 4C Eye Tracker.
Unfortunately, due to the nature of the problem (ie hardware based) there is little one can do on existing EyeX Units to rectify the issue other than using a 5Ghz Wifi router which consistently has shown to be an effective solution.
Apologies there is not further recommendations we can provide.
