DFF1-UHD no signal

I have a DFF1-UHD hooked to a laptop and TZ Professional program. The unit was installed last summer and worked fine all summer. I recently fired it up and got a no signal received on the laptop, the green LED on the sounder is on full time when the unit is powered up. Any thoughts where I should start, to see if I can get it functioning without sending it to the shop?
 
When the sounder light goes solid after 4 mins of power on; it means it doesn't see a NavNet or TimeZero computer to talk to. I would say you have a network connection issue.
 
Hmm, has this laptop been used for anything else since last summer? :think

The DFF1-UHD lives on a static ip of 172.31.92.2 with a subnet mask of 255.255.0.0

1. You could ping the DFF1-UHD box and see if it's there.

Code:
ping -t 172.31.92.2
in the Command Prompt

2. If using Timezero, use the "navigate mode" over the "home planning" mode
3. Statically assign the PC to an IP of 172.31.3.150 with a subnet mask of 255.255.0.0 and re-evaluate the situation
4. Check your network cables

Likely either one of these solutions should give you a next step to investigate,

Hope this helps, :sail
