Once you have downloaded your new driver, you'll need to install it. In Windows, use a built-in utility called Device Manager, which allows you to see all of the devices recognized by your system, and the drivers associated with them.

The second manufacturer is who makes the wireless chipset within the card. This is the most important company to know. Unfortunately, it is sometimes the hardest to determine. This is because card manufacturers generally don't want to reveal what they use inside their card. However, for our purposes, it is critical to know the wireless chipset manufacturer. Knowing the wireless chipset manufacturer allows you to determine which operating systems are supported, software drivers you need and what limitations are associated with them. The compatibility section describes the operating systems supported and limitations by chipset.

Once you have determined the chipset, check the driver section for which software driver you need. Software drivers connect the operating system to the hardware. The drivers are different for each operating system. There are also notes regarding limitations.

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, but it is recommended, because its one of the cheapest chips (about 5, 6$ on eBay) supported by aircrack-ng and offers reliable and stable operation for wireless connectivity. Starting with 2.6.24, AR5007UG(zd1211/zd1211b) can be used with zd1211rw. Madwifi-ng is deprecated and now most supported cards by madwifi-ng should be supported by ath5k or ath9k.

Another USB chipset, AR9170, which covers Atheros and Zydas chipsets (zd1221) also provides aircrack-ng support with a mac80211 driver called carl9170. So does the ath9_htc for USB chips: AR9271 and AR7010.

As of kernel 2.6.26 and later, a new driver has been incorporated named as ath5k. This driver, unlike the madwifi-ng driver which requires HAL and was previously proprietary is a HAL-free based driver. Most popular linux distributions would already have this driver included which should provide support for those using such chipsets and preferrably to try injection patches on this driver before reverting back to the madwifi-ng.

Like Madwifi, b43 offers no support for Broadcom-based USB devices. For those, a separate driver called rndis_wlan exists, which doesn't support monitor mode (and will never do so, as the chipset has no raw mode). Draft-N devices are also not yet supported.

Users whom use broadcom linux_sta driver (otherwise known as wl) should note that there are no monitor/injection modes with such driver. Broadcom deliberately removed the functionality out of their proprietary binary blob. Read here for more info: Also b43 supports less than a handful of chipsets, take note on which ones are unsupported and see if yours fall into that category: b43

Intel wireless cards are common devices found inside most laptops apart from Broadcom, Atheros, Ralink and Realtek. These devices has native linux support and generally do work well for most parts except for Intel's older chipsets such as ipw2200. 3945 owners are recommended to use iwl3945 as the older driver ipw3945 does not have monitor or injection capability and requires ipwraw-ng and is often not easy to work with ipwraw-ng. Owners of 4965 and later has support with iwlagn.

The legacy chipsets, namely Intersil Prism 2, Prism 2.5 and Prism 3 struggle in terms of support as the owners are slowly fading away. The drivers were split between the connecting interfaces on linux platform. Pre prismGT models had the hostap driver for most PCI/PCMCIA cards and wlan-ng for USB devices. These drivers are based on legacy stack and has two main drawbacks:

1) They are buggy in which they would operate, for example wlan-ng does not obey iwconfig commands and requires its tool in order to change the modes, even to turn the device on so that iwconfig will start displaying information from the driver.

2) The injection patches only work on older kernels, so for kernels beyond 2.6.20 will not inject properly. So if one were to continue using legacy chipsets, they must use older kernel, old drivers and firmware or they will not gain the extra features.

As for Intersil/Conexant PrismGT chipsets, the support for these on linux has been making a comeback. Initially the prism54 driver is only able to support fullMAC cards, the support for softMAC cards were all over the place such as the use of islsm. As of kernel 2.6.26, a new driver p54 has been incorporated with plans to merge both fullMAC and softMAC support of Intersil/Conexant PrismGT product range. The initial code was buggy but users with >=2.6.28 kernel will benefit regardless of which PrismGT they own.

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.

As of kernels >= 2.6.26 there are mac80211 based drivers which should give better support for almost all Ralink chipsets. As for Ralink 802.11n capable devices, they are slowly gaining support, read here.

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 with this chipset and it performs well the aircrack-ng suite. This chipset is not to be confused with the RTL8187B, which is nowhere near as tested as RTL8187L.

FreeBSD will take advantage of Physical Address Extensions (PAE)support on CPUs that support this feature. A kernel with thePAE feature enabled will detect memory above 4gigabytes and allow it to be used by the system. This featureplaces constraints on the device drivers and other features ofFreeBSD which may be used; consult the pae(4) manual page for more details.

Most modern laptops (as well as many desktops) use the AdvancedConfiguration and Power Management (ACPI) standard. FreeBSDsupports ACPI via the ACPI Component Architecture referenceimplementation from Intel, as described in the acpi(4) manual page. The use of ACPI causes instabilities onsome machines and it may be necessary to disable the ACPI driver,which is normally loaded via a kernel module. This may beaccomplished by adding the following line to/boot/device.hints:

Where possible, the drivers applicable to each device or classof devices is listed. If the driver in question has a manual pagein the FreeBSD base distribution (most should), it is referencedhere. Information on specific models of supported devices,controllers, etc. can be found in the manual pages. 2ff7e9595c
