Broadcom wifi chipsets differ mainly by PHY (and radio). You can take a look at: http://wireless.kernel.org/en/users/Drivers/b43#Supported_devices When checking/adding support for some Broadcom WiFi, the most important is to check PHY type. Each PHY type requires separated code in a b43 driver. Example PHY types: A, B, G, LP, N, HT, LCN, LCNXN, LCN40, AC. Having a 802.11bg capable card doesn't determine a PHY that is used. It can be G as well as LP. Having 802.11n card also can mean N, or HT, or some other. BCM4318 is a chipset that AFAIK always has a G-PHY in it. BCM5354 is a chipset that AFAIK always uses LP-PHY. It means that the two chipsets above are handled by a lot of different code in b43 driver. Please note, that some Broadcom based devices are even more /complicated/. Some chipsets don't have a WiFi core at all, I think BCM4706 is a example of such a chipset. BCM4706 by itself doesn't do any WiFi stuff. It has PCIE slots however. This way other Broadcom chipsets can be attached to the wifi-less BCM4706. For example Netgear WND4500 is based on (wifi-less) BCM4706, but it has attached two BCM4331 chipsets. This is the way it handled wifi - by an additional (PCIE) chipsets. >> After seeing log I can tell it's standard BCM5354 with a 80211 core that > has: >> b43-phy0: Found PHY: Analog 6, Type 5 (LP), Revision 0 >> There is no separated chipset with just wireless, it's just a mistake on > wiki page :) >> [0] http://wiki.openwrt.org/toh/huawei/e970 > > I must admit that I haven't done very thorough research when filling in > the hardware table :) merely copied the relevant bits from pages of other > devices with BCM5354.

Well, maybe there are some wifi-less BCM5354 chipsets with an additional (PCIE?) BCM4318 chipset. But E970 is not an example of such a device. > Anyway I just changed the E970 wiki page.
