Hi I own a Linksys WPC54G card with a BCM4306 chipset which requires b43legacy.
The card worked with the bcm43xx driver. I now compiled the latest (march 25) wireless-testing kernel and use now the b43legacy driver. The card seems working, I notice however the same behavior David Ellingsworth in his post described (http://lists.berlios.de/pipermail/bcm43xx-dev/2007-August/005733.html). Only 1 Mbit/s despite good link quality and constant reassociation. I use the card at the university where many access points are installed. Did anybody observe the same behavior or is there already a solution? Here the syslog output: Loading the module (modprobe b43legacy): pccard: CardBus card inserted into slot 1 PCI: Enabling device 0000:06:00.0 (0000 -> 0002) ACPI: PCI Interrupt 0000:06:00.0[A] -> Link [LNKB] -> GSI 4 (level, low) -> IRQ 4 PCI: Setting latency timer of device 0000:06:00.0 to 64 ssb: Core 0 found: ChipCommon (cc 0x800, rev 0x02, vendor 0x4243) ssb: Core 1 found: IEEE 802.11 (cc 0x812, rev 0x04, vendor 0x4243) ssb: Core 2 found: PCMCIA (cc 0x80D, rev 0x01, vendor 0x4243) ssb: Core 3 found: V90 (cc 0x807, rev 0x01, vendor 0x4243) ssb: Core 4 found: PCI (cc 0x804, rev 0x07, vendor 0x4243) ssb: Core 5 found: IEEE 802.11 (cc 0x812, rev 0x04, vendor 0x4243) ssb: Ignoring additional 802.11 core ssb: SPROM revision 1 detected. ssb: Sonics Silicon Backplane found on PCI device 0000:06:00.0 b43legacy-phy0: Broadcom 4306 WLAN found b43legacy-phy0 debug: Found PHY: Analog 1, Type 2, Revision 1 b43legacy-phy0 debug: Found Radio: Manuf 0x17F, Version 0x2050, Revision 2 b43legacy-phy0 debug: Radio initialized phy0: Selected rate control algorithm 'pid' Broadcom 43xx-legacy driver loaded [ Features: PID, Firmware-ID: FW10 ] Bringing the interface up (ifconfig wlan0 up), the firmware gets loaded: b43legacy-phy0: Loading firmware version 0x127, patch level 14 (2005-04-18 02:36:27) b43legacy-phy0 debug: Chip initialized b43legacy-phy0 debug: 30-bit DMA initialized b43legacy-phy0 debug: Wireless interface started b43legacy-phy0 debug: Adding Interface type 2 Configure the essid (iwconfig wlan0 essid yyyy), the device associates wlan0: Initial auth_alg=0 wlan0: authenticate with AP 00:xx:xx:xx:xx:xx wlan0: RX authentication from 00:xx:xx:xx:xx:xx (alg=0 transaction=2 status=0) wlan0: authenticated wlan0: associate with AP 00:xx:xx:xx:xx:xx wlan0: authentication frame received from 00:xx:xx:xx:xx:xx, but not in authenticate state - ignored wlan0: authentication frame received from 00:xx:xx:xx:xx:xx, but not in authenticate state - ignored wlan0: RX AssocResp from 00:xx:xx:xx:xx:xx (capab=0x421 status=0 aid=103) wlan0: associated Now the network connection is up and I can access the internet.
