Wireless Card that supports promiscuous mode in Windows 7 Ask Question. The best answers are voted up and rise to the top.
You might check the Linux Wi-Fi driver community to find out which cards use Atheros chips and support the "Madwifi" driver well, and then pick one of those they're more likely to have a Windows driver that supports monitor mode well. Of those, Atheros has long been the best chipset vendor for monitor-mode support, and open source support. The biggest vendors are Broadcom, Atheros, Marvell, and Intel, and there are several smaller lesser-known vendors such as Ralink.
It shows not only the data frames you'd see on wired Ethernet, but also the And it shows them untranslated, with their full Full Many Update: It's also important to note that there are really only a few Wi-Fi chipset vendors out there, and all the card makers use chips from those few vendors. If there are other Wi-Fi networks in range on that channel, it shows you the frames from those other networks as well. In full monitor mode, the card is tuned to a channel and shows all the packets it can receive on that channel, no matter what. Many but not all Wi-Fi cards support promiscuous mode, in a way that looks a lot like Ethernet promiscuous mode it shows only the "data" frames, only on your current network same BSSIDand it shows them after they've been translated into wired-Ethernet-style packets Ethernet-II or The idea is to make it look just like the same traffic you'd see on a wired Ethernet interface in promiscuous mode, for the sake of network engineers that want to look at things at that level. Has anyone had any experience getting this to work? Promiscuous mode is a concept that originated on wired Ethernet, where you have your card show you all the traffic your hub is repeating onto your port, even if it's not addressed to you. I'm trying to use wireshark to learn a bit about networking and capturing packets. Super User is a question and answer site for computer enthusiasts and power users. Often, monitor mode is required to capture certain frames for wireless penetration testing, but it may be unethical or even illegal to capture frames on any network you do not own, manage or have permission to perform penetration testing against.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. Monitor mode is used to capture This can be useful for diagnosing issues on a network or testing the security of your wireless network. It is recommending that you blacklist conflicting modules. To make the module load at boot, refer to Kernel modules.
Install the appropriate driver for your system architecture from Broadcom's website. Then, use another Internet-connected computer to download linux-headers and the driver tarball from the AUR, and install them in that order. If you have neither, you'll need to first install the base-devel group during installation.
The factual accuracy of this article or section is disputed.Īn Internet connection is the ideal way to install the broadcom-wl driver many newer laptops with Broadcom cards forgo Ethernet ports, so a USB Ethernet adapter or Android tethering may be helpful.
Both of these drivers require non-free firmware to function. To avoid erroneous detection of your WiFi card's chipset, blacklist the unused driver. Two reverse-engineered open-source drivers are built-in to the kernel: b43 and b43legacy. They should be automatically loaded when booting. To know what driver s are operable on the computer's Broadcom wireless network device, the device ID and chipset name will need to be detected.Ĭross-reference them with the driver list of supported brcm and b43 devices. In SeptemberBroadcom released a fully open source driver. In AugustBroadcom released the This is a restrictively licensed driver and it does not work with hidden ESSIDs, but Broadcom promised to work towards a more open approach in the future. The reverse-engineered b43 driver was introduced in the 2. The limited set of wireless devices that were supported were done so by a reverse-engineered driver. For a good portion of its initial history, Broadcom devices were either entirely unsupported or required the user to tinker with the firmware.
