Try going through the instructions again on https://hub.vive.com/storage/docs/en-us/UnityXR/UnityXRDirectPreview.html 

First thing i found out was to make sure the headset is connected by usb and after changing the wifi address or any other configuration, make sure to "push apk" which also uploads the new configuration. 

Let's make sure that the headset is reachable from the pc that is streaming.

1) Find the IP of the headset, for example might be
     a) - likely on the same network
     b) or something along the lines of or -- if they look this different, the headset may be connected to a different network
2)  Even when connected to the same network, sometimes the network prevents devices from talking to one another.
       So lets make sure that the headset is reachable from the pc by finding the ip of the headset, for this example let's use ""
     a)Open cmd
  b)run ping command against the ip address of the headset (in this example I assume the headset is at "")

If it looks like this, then the two devices cannot talk to one another
c) consult the network administrator or network admin panel if you own this network (for me, it's at ) and consult documents to make sure that there are no firewall rules preventing udp traffic
d) make sure that if your pc that is streaming is on multiple networks, to set the device ip using the dialog shown in your post. otherwise it shouldn't be necessary. this happens if the pc has a wireless adapter and a wired adapter both connected, for instance. 

For my own personal example:
This is something I have to consult occasionally as I have a few home networks. If I find my headset's current ip, i go to settings->general->about and then headset status, and that popup will show the ip address
Open Settings

Open About headset 

In the above picture, I notice that my ip address is "" which I happen to know is on a different network than my pc. 
I can verify this as it's not reachable when I try to ping it

I then go into my network settings and change my connection to my other network
Then verify that I'm on the same network by going back through general->about->headset status again

Here I notice my headset's ip address "" is now reachable from my pc
