I’m running Wireshark on a Mac (M2 Mini). I have an AV Receiver with a wifi interface, and an iPhone 14. I’m trying to capture the traffic (I understand it is UDP) between an app on the iphone and the receiver, but not getting anything. I assume it is something basic that I don’t understand about how to set up wireshark, or something about my network setup. As far as i know, the traffic is not encrypted.

  • I have a TP-Link wifi mesh network with 3 nodes.
  • The Mac is connected to the same wifi network as the iphone and receiver.
  • The iphone and Mac are on the same node of the mesh network, the receiver is on a different node
  • The Mac also has an ethernet connection to the TP-Link router.
  • I have the IP addresses of the receiver (10.0.1.19) and iPhone (10.0.1.12).
  • i can successfully ping the receiver from the Mac

I selected both the wifi and ethernet interface on the mac and tried the following filter: host 10.0.1.19 && host 10.0.1.12 && udp

However nothing is captured as i use the iPhone app to make changes on the receiver. I tried removing “udp” from the filter, same thing.

Would appreciate any suggestions as to why this is not working…

thanks!

Can you make a packet capture on the router?

No, it is TPlink Deco router, i don’t see any way to capture traffic from the Deco app, assuming that is what you mean.

Yep. Capture there probably would have been easier.
Wireless capture (and on a Mac to boot) not my strength.
Add those to the question title and lets see if someone stronger in wireless helps.
