In September 2010, Broadcom released a fully open source driver. The brcm80211 driver was introduced in the 2.6.37 kernel and in the 2.6.39 kernel it was sub-divided into the brcmsmac and brcmfmac drivers.
Two reverse-engineered open-source drivers are built-in to the kernel: b43 and b43legacy. b43 supports most newer Broadcom chipsets, while the b43legacy driver only supports the early BCM4301 and BCM4306 rev.2 chipsets. To avoid erroneous detection of your WiFi cards chipset, blacklist the unused driver.
Bcm4313 Drivers For Mac
Be sure the correct modules are blacklisted and occasionally it may be necessary to blacklist the brcm80211 drivers if accidentally detected before the wl driver is loaded. Furthermore, update the modules dependencies depmod -a, verify the wireless interface with ip addr, kernel upgrades will require an upgrade of the non-DKMS package.
On two of the three have been broadcom bc4312 the other I had to manually install and configure the wireless drivers. Never ran into the problem I'm having with this card, I think it's confusing as its a hybrid bluetooth and wireless card in one.
I know that this may seem like a strange way to solve things, but if you were to go to the LINUX forums you can download the drivers source code and compile it yourself. All it takes is a vertual machine and you can have the latest bleeding edge drivers running your rig. It's what I do.
This is mainly for NDIS5 drivers. The NDIS6 drivers are not supported yet.Link: -wifi-broadcom-bcm4312-on-dell-vostro-1710/ Fetch all the required packages & files and store them in a common directory
My WiFi device is BCM 4313, recognized as pciex14e4,4727. I've tested out Jean-Pierre's works based on older and newer ndis code, however, so far I couldn't forge a driver that would support my card. Apparently, newer BCMWL drivers make calls that are not implemented by the NDIS emulation layer - though there are much less of missing symbols in ndis-1.2.6-based version.
I gave this a shot and it builds on my box with gcc-4.4.4-il now, although with several warnings. Linked with the older bcmwl drivers (which you use for your card) the NDIS driver even loads cleanly, both with your ndisapi and with a freshly-built one. However, as before, this driver version does not support my own card.
Other bcmwl* drivers that I tried to feed it, that are supposed to support my card, did not modload, due to not finding several symbols (below). One driver did not get processed into a driver.s file (though it did before, when I tried with stock gcc-3.4.3). I can't say if it was GCC's fault, or if you changed something in ndiscvt to such effect, but the curious fact is there.
I have uploaded to -andre.pagesperso-orange.fr/ndis.1.3.0.rc2.tar.gza release candidate for an ndis emulator which can emulate the NDIS5 interface in 64-bit mode for Broadcom wireless drivers designed for Windows.
Note that, as the explanative post specifies, the emulator is developed to implement certain Windows API routines as used by particular builds of binary drivers. That is, it is not "granted" that any driver version, older or newer than those tested during development, will work out of the box.
Also, these drivers are not illumos-architected WiFi drivers; the security (WEP/WPA) support for example is part of the Windows API implementation and not really aligned with the OS. This version in particular does not support WPA, and Jean-Pierre did not need that, so it is up to some other developer to add the support if needed.
The contrib/ directory includes my init-script with logic similar to that seen in the Makefile to load, configure or unplumb and unload the interfaces and their drivers. This may be convenient to have the WiFi parts start up later in the system initialization, including manual startup or via /etc/rc3.d for example, so that some waiting for the network to be found and DHCP config to be acquired wouldn't noticeably delay initialization of the rest of your system - especially if you're out of reach for the WiFi radio (fail-timeouts are quite long).
Wireless network cards for computers require control software to make them function (firmware, device drivers). This is a list of the status of some open-source drivers for 802.11 wireless network cards.
I have a similar mac that I run Arch on assuming you have a broadcom card there are three possible drivers that may (or may not) work. (broadcom-wl) works for me. Also check pm-utils for powersaving settings. Further details on both can be found on the Arch wiki here
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 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:
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.
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. 2ff7e9595c
