I have a BCM4309 14e4:4324 (rev 02) chipset and it drops connection from time to time with this driver.
It connects fine at 1Mbps, really quick link establishment, but maybe half an hour later it drops and reconnects again. There are lots of messages in the kernel log, I'm including here what I think is useful: this is what I get when it first initialises: b43-phy1: Broadcom 4306 WLAN found b43-phy1 debug: Found PHY: Analog 1, Type 2, Revision 1 b43-phy1 debug: Found Radio: Manuf 0x17F, Version 0x2050, Revision 2 b43-phy1 debug: Radio turned off wmaster0: Selected rate control algorithm 'simple' b43-phy1 debug: Ignoring unconnected 802.11 core b43-phy1 debug: Adding Interface type 2 b43-phy1 debug: Loading firmware version 351.126 (2006-07-29 05:54:02) b43-phy1 debug: Radio turned on b43-phy1 debug: Radio enabled by hardware b43-phy1 ERROR: bbatt(11) >= size of LO array b43-phy1 debug: Chip initialized b43-phy1 debug: 30-bit DMA initialized b43-wlan: TODO: Incomplete code in keymac_write() at drivers/net/wireless/b43/main .c:753 *<---- repeated several times* b43-phy1 debug: Wireless interface started ADDRCONF(NETDEV_UP): wlan0: link is not ready wlan0: Initial auth_alg=0 wlan0: authenticate with AP 00:30:bd:fe:23:83 wlan0: RX authentication from 00:30:bd:fe:23:83 (alg=0 transaction=2 status=0) wlan0: authenticated wlan0: associate with AP 00:30:bd:fe:23:83 wlan0: RX AssocResp from 00:30:bd:fe:23:83 (capab=0x411 status=0 aid=10) wlan0: associated wlan0: switched to short barker preamble (BSSID=00:30:bd:fe:23:83) ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready when it drops connection I get the following messages in dmesg: wlan0: No ProbeResp from current AP 00:30:bd:fe:23:83 - assume out of range b43-phy1 debug: Using software based encryption for keyidx: 0, mac: 00:30:bd:fe:23 :83 wlan0: No STA entry for own AP 00:30:bd:fe:23:83 wlan0: No STA entry for own AP 00:30:bd:fe:23:83 wlan0: No STA entry for own AP 00:30:bd:fe:23:83 ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready b43-phy1 debug: Removing Interface type 2 b43-phy1 ERROR: MAC suspend failed b43-phy1 debug: Wireless interface stopped b43-phy1 debug: DMA-32 0x0260 (RX) max used slots: 1/64 b43-phy1 debug: DMA-32 0x0200 (RX) max used slots: 2/64 b43-phy1 debug: DMA-32 0x02A0 (TX) max used slots: 0/128 b43-phy1 debug: DMA-32 0x0280 (TX) max used slots: 0/128 b43-phy1 debug: DMA-32 0x0260 (TX) max used slots: 0/128 b43-phy1 debug: DMA-32 0x0240 (TX) max used slots: 0/128 b43-phy1 debug: DMA-32 0x0220 (TX) max used slots: 92/128 b43-phy1 debug: DMA-32 0x0200 (TX) max used slots: 0/128 b43-phy1 debug: Radio turned off b43-phy1 debug: Radio turned off b43-phy1 debug: Adding Interface type 2 this is the link quality info: Bit Rate=1 Mb/s Retry min limit:7 RTS thr:off Fragment thr=2346 B Link Quality=73/100 Signal level=-56 dBm Noise level=-41 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 is the SNR low? Is that why it drops the connection ?
