However, Guidelines for 802.11 Promiscuous Receive Operations says: Note When the miniport driver is in Native 802.11 modes other than NetMon, and OID_GEN_CURRENT_PACKET_FILTER is set, the driver must not fail the set request if any promiscuous or raw filter settings are enabled in the OID data. To quote the page for the OID_GEN_CURRENT_PACKET_FILTER OID: On Windows, however, it's not clear whether 'promiscuous' mode, as opposed to monitor mode, is supported on 802.11 adapters. The AR 9271 data sheet has a PROMISCUOUS bit in the receive filter register, described as 'Promiscuous receive enable Enable reception of all frames, including errors', which sounds like monitor mode.Īnd, in fact, the Linux ath9k driver turns that bit on for monitor mode. And one more thing.Alfa's page for the AWUS036NHA says the chipset is the Atheros AR9271. I have NPCap installed (equivalent to WinPCap, but for Windows 10 that doesn't support the WinPCap driver), and I know it supports promiscuous mode, but I don't know if it is capable of enabling monitor mode in wifi adapters that support monitor mode, or if I need to install a special hacked driver for that specific wifi adapter to replace its normal driver in order to enable monitor mode. Now here's what I'm not completely sure about, regarding monitor mode in Windows (and yes, I've heard that it is possible). However, I don't think most cards support monitor mode (at least not in Windows, but I heard that it's easier to do in Linux). In this mode, it a network card receives all wi-fi packets, not just those associated with the currently connected network (and I don't even think that a network card can connect to a network the standard way when in monitor mode). But there's another mode also that some cards support, but others don't it seems (and mine might not it seems), and this mode is called monitor mode. In WireShark software there's promiscuous mode, which lets you monitor all packets on the currently connected wireless network (rather than just those intended for your computer).
