I want to monitor packet in my network. It said that ARP packet request broadcasted all over network. But why i only see my arp request packet and reply packet to the gateway?

    What are you using to monitor? You need to configure your wireless device to run in “monitor “ mode. It’s equivalent to promiscuous mode for an Ethernet sniffer. – Ron Trunk Oct 2 '18 at 13:00

I don't know how do you monitor ARP packet but I think what you see is correct. Here are the reasons:

First, you ARQ request packet will be broadcast to LAN by switches. Your computer only needs to send one ARQ request packet and the broadcast is done by switches. So the monitor shows your ARQ request packet as an indication for this step.

Second, the gateway router sent the ARQ reply packet to you (unicast because the switch is self-learning) by the switches. So the monitor only shows ARQ reply packet from the gateway router as the indication for this step.


You can add a TAP between your access point and the switch. Of course you can set a monitor session on all wifi interfaces. I think it’s the simple way to monitor packets transfered by your network. You will be able to see ARP because you AP by default just passthrough all packets except bacons.
