touch screen doesn't connect to wifi

I picked up a new Gateway box 2 weeks ago. I was able to connect all my devices to the new Wi-Fi except the Home Security Touch Screen. After about 2 hours on the phone with 2 agents, we were able to connect. However, since then I keep losing Wi-Fi connection on the Home Security Touch Screen and have to restart both the Gateway and Touch Screen. No other devices are having connectivity issues. I really think I need a new Touch Screen for my Home Security, but I can't seem to connect to a live Agent to schedule an appointment to replace the Touch Screen as I think it has difficulty connecting to the newer version of the Gateway. Thanks
