I cannot connect my VLP-16 to LidarView or VeloView using the sensor configure option. I am also not seeing any UDP location in wireshark. I also cannot access the web ui but can ping the lidar.

Please review the following post to find a Velodyne sensor. Based on the view above, if the sensor does not find the host name in its Configuration on the network, it will not begin sending packets:

Can you please help us in this Answer: The following two tools are helpful for resolving this issue: Wireshark: [Wireshark · Download](https://www.wireshark.org/download.html) Veloview: [VeloView: The Velodyne Lidar Viewer based on Paraview Lidar](https://www.paraview.org/veloview) (this version of Paraview has the Velodyne sensor configurations preloaded) Assuming the sensor is powered and operating with…

We believe OP worked with support and was able to resolve it. The Host (Destination) address was set to 192.168.1.77 but the IP Address was set to 10.0.X.X and the gateway was set to 10.0.Y.Y  
If the network configurations are unknown to the user, we advise:

1. Check ethernet port link lights are on to verify a connection has been established

- DHCP configured sensor: run `arp -a`

- Connect the sensor to a directly to a computer and run a packet capture (e.g. wireshark, tcpdump) on the whole NIC/port
