How to debug network data on Nexus 5/7

Hi Guys,

I am having an issue on my devices where certain apps won't refresh/sync when I'm on wifi after getting a new router. I have no idea what's causing it. Is there any way to see a debug log of what the network connection is trying to do when apps are trying to refresh? Hoping it might provide me with some clues as to what's going wrong.

There's one tool for that, and always has been - Wireshark.

Thanks :)

Hopefully I can get to the bottom of this....
