Cards containing the Realtek RTL8187L chipset work quite well and is recommended. The driver patch for this chipset has been continuously improved and quite good at this point in time. The Alfa AWUS036H is a very popular card for use with the aircrack-ng suite.

Ralink makes some nice b/g chipsets, and has been very cooperative with the open-source community to release GPL drivers. Packet injection is now fully supported under Linux on PCI/CardBus RT2500 cards, and also works on USB RT2570 devices. However, these cards are very temperamental, hard to get working, and have a tendency to work for a while then stop working for no reason. Furthermore, the RT2570 driver (such as that for the chipset inside the Linksys WUSB54Gv4) is currently unusable on big endian systems, such as the PowerPC. Cards with Ralink chipsets should not be your first choice. There is one exception with regards to the Ralink chipsets. This is the RT73 chipset. There are excellent drivers with high injection rates for the RT73 chipset. Devices with the RT73 chipsets are recommended.

The best chipset nowadays is Atheros. It is very well supported under Linux, and also under Windows. Neither support any USB wireless devices. The latest madwifi-ng patch makes it possible to inject raw 802.11 packets in either in Managed and Monitor mode at arbitrary b/g speeds. The madwifi-ng compatability list is an excellent way to determine if a card is compatible with the aircrack-ng suite. Atheros, the chipset manufacturer, also has a web page that enables you to lookup chipsets for products incorporating their designs. The madwifi-ng driver is used for the atheros chipsets. This driver does not support any USB atheros devices. However, Atheros acquired Zydas which makes USB chipsets (zd1211 and zd1211b). Atheros has renamed this chipset to AR5007UG. The AR5007UG chipset is NOT supported by the madwifi-ng driver and is not a recommended chipset.

A virtual machine is available here . See this page for more information. A second, very light VMWare (15Mb required on disk) machine is available here . This machine currently only works with RT73. See this thread on the forum for more information. I know that a lot of people are clamoring over Windows packet injection, since it's a nice thing to have if you don't want to run Linux. The only issue is that if you've got a PCI based card, and there are no Windows drivers, then there is no way to run such a device without rebooting into Linux.There are several reasons why this came about:- I don't want to mess with my host WLAN drivers. I also don't want to hack an RP-SMA connector into a $$$$ UMPC.- I needed something that would not require me to reboot in order to reset it- I didn't want to fool around with Commview (evaluation software) and or DLL's and stuff- I had a nice RT73 device with a RP-SMA connector on it from the factorySo, I set out to create a...

Debian and Nokia LD-3W GPS Dongle It is a while now I bought a Nokia LD-3W, my dream was a connection between my notebook and this little GPS receiver.How-To Connecting the LD-3W is quite simple, if you know how to do it. The only prerequisite is that you have already bluetooth kernel support.PreparationsPackages Install following package: apt-get install bluez-utils gpsd gpsd-clients Use of Bluez-Utils (Find LD-3W) At first you need to find your LD-3W.

This post will list my adventures with my newly acquired Nokia E51 on Linux ( Ubuntu 7.04 )Interfacing the Nokia E51 with the computer can be done by: USB Data cable Bluetooth Infrared #1. Talking to the Phone via USB data cable:The phone comes with a mini USB 2.0 port which can be connected to the USB port of my computer.Plug-in the USB data cable to the computer and then to the phone.You get a pop-up on your phone, asking for the transfer mode: PC-Suite Data Transfer My understanding is that the PC-Suite mode is for communicating with the "whole" phone using the Nokia PC Suite Software. This mode enables you to talk with all the features of your phone. We shall be using this mode for many of our tasks here on Linux, but without using Nokia PC Suite.The Data Transfer mode is for interacting only with the Memory Card that comes with the phone. Once you select this mode, the memory card is available for access from your computer and is inaccessible from your phone.Listed belo...
