With all of them, I don't see all packets and it looks they fail to enter promiscuous mode: once I see the very first ARP-RQ, I don't see anything else between the two devices. I tried: Intel Link 5100 AGN Linksys Wireless-G Qualcomm Atheros AR928X Can you confirm promiscuous mode is NOT what I need? Yes, I red carefully (I hope) "WLAN (IEEE 802.11) capture setup" paragrph, but I am confused: I don't need to capture radio-level, I don't need to capture all SSID's but I need to see packets not directed to me. I do't need to trace at radio level, but I just need (want!) to see from Ethernet level, so I guess I simply need a WiFi card/adapter/dongle able to accept "promiscuous" mode. To set an interface to promiscuous mode you can use either of these commands, using the ‘ip’ command is the most current way.Hello, I need to trace between two WiFi devices, connected to the same A.P. How to Manually set a NIC in Promiscuous Mode?

In bridge network, the NIC is mostly required to operate in promiscuous mode.

If a Network monitor tool is used, like tcpdump etc.

If it was manually configured in that mode using ifconfig command.

A network card usually is in promiscuous mode when: Suppose for eth1, promiscuous mode is basically used to pass all traffic that ‘eth1’ receives rather than just frames addressed to it. When a network card is in promiscuous mode, it can read all traffic it received rather than just packages addressed to it. Otherwise, deep investigation on that system will be required due to a security issue. If there was such program intentionally running or bridged networking for hardware virtualization, the “promiscuous mode” message might be simply ignored. It is usually used by a packet sniffing program like Wireshark, and tcpdump. Promiscuous mode or promisc mode is a feature that makes the ethernet card pass all traffic it received to the kernel.
