Cannot Capture WiFi Traffic
Hi,
Sorry for the basic question but I am really out of my league here.
I've read https://wiki.wireshark.org/CaptureSet... and I'm confused as whether I can even do what I want to do.
I have a stand-alone box which talks over WiFi only. My PC running Win10 can connect to my router either over WiFi or wired. (I've tried both.) My box is doing a GET to a site which works only about 20% of the time. The GETs are identical, except for a time stamp so that indicates it isn't an error in the GET command. The other 80% of the GETs appear to contain NULL data as far as the box goes. I can see all of this on a debug port.
What I can't see is the actual packets going to and from the site I'm talking to. I believe if I could see this I might understand why I'm losing 80%.
Is there a way to do this in Windows, or am I chasing a lost cause? If possible, how do I do it?
Thanks for your time.
Computers connected to a basic Wi-Fi or switch port will only be able to see traffic for its MAC address or multicast. Capturing Wi-Fi can be challenging because it is not plug-n-play. The simplest way to capture packets is between the stand-alone box and the router. If there is a switch between them, you can create a mirror port and direct mirror traffic to the laptop. If there isn't a switch, then use a hub or TAP. If the trouble is local, this packet capture will show it.
