Network Application Questions

Hi all,

I have the Network Application installed in a Docker Container on my NAS and have a couple of questions regarding the image below.

1. Can I find the device(s) related to this download? I'm sure you can but I cannot find where.
2. How accurate are the download and upload figures? This download showed 10MB/s in Windows but only 13.2Mbps in the UNA.

TIA

EDIT: Under Unifi Devices the download showed 195Mbps.
