Per device connections monitoring
This is already pretty good to monitor current connections happening on the router.

But I am looking for something like CommView where you can select which of your local devices you would like to analyze / monitor.
Is there any luci package or way to connect to the router with wireshark and do a live analyzis for specific clients?

You can connect to Wireshark by running tcpdump (-mini) over SSH. Keyed access makes things simpler.


if you have extroot and skills, ntop is nice for analysis
