This is our old Q&A Site. Please post any new questions and answers at ask.wireshark.org.

I'm using Wireshark to monitor network traffinc to test a new software installed on a router. The router itself lets other networks (4g, mobile devices through usb etc) connect to it and enhance the speed on that router.

What I'm trying to do is to disconnect the connected devices and discover if there are any packet losses while doing this. I know I can simply use a filter stating "tcp.analysis.lost_segment" to track down lost packets, but how can I eventually isolate the specific device that causes the packet loss? Or even know if the reason was because of a disconnected device when there is a loss?

Also, what is the most stable method to test this with? To download a big file? To stream a video? Etc etc

All input is greatly appreciated

without being able to predict the future, I can predict that there will be packet loss if you do that.

BTW: You told us nothing about the following things, which makes it hard/impossible to give any good answer!!

  • how are the devices connected to the router? wlan/wifi, ethernet, 4G?
  • what kind of devices are these?
  • how do you plan to 'disconnect' the devices?
  • do you expect to get no packet loss at all?
  • what exactly is the router doing, while it is 'enhancing the speed'?
  • what kind of router / router software is this?
  • there will be packet loss, so what kind of insight do you hope to get by looking at the 'line' (air, etherhnet, etc.) while you disconnect the devices?
