Packet loss and losing internet connection

Every x minutes I'm losing connection when gaming or streaming a Citrix session (my guess is packet loss). And every x minutes my OS even says i lost connection with the internet. Does wireshark reveals anything why? I want to include logs but need 60 points, what is next?

You don't describe what internet connection you have, but the problem is likely to be between your router and the ISP which isn't easy to capture on. Maybe better taking this up with your ISP.

I have a fiber connection of 50 Mbit. My best guess is my UTP cable but can't replace it easy because it is around 15 meter and goes through a wall upstairs. Is a wireshark log able to identify a cable issue?

I also have a budget ISP at the moment so don't expect much help from them...

UTP cable between what, your Fiber router and your PC? Cable problems don't show up as such in a Wireshark capture, mainly they cause lots of other random traffic errors. Can't you move the PC closer to the router to test with a spare cable?

It is the cable between the router and the PC, yes. In theorie moving my PC is possible but hard to put in practice because that means working in the living room. Can i inlcude logs somewhere so you can see if there are random traffic errors that might suspect the UTP cable issue?

Wireshark can show you what network traffic is flowing as far it passes the network interface you capture on. If this traffic is not passing it, it can't show it. In short it can tell you the what, but not the why. Anything wrong at the physical layer (as cables and stuff are called) can't be seen. That is the domain of network drivers, etc, so totally depends on your operating system, which manages those.

you know a good tool to diagnose at driver level and a community that can help in these cases?
