I ran update-pciids successfully, now dmesg says: b43-phy0: Broadcom 4311 WLAN found (core revision 13) and lspci: 02:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11a/b/g [14e4:4312] (rev 02) > Also, could you check a few more kernels in-between .29 and .32? > I have checked the following kernels, and found they all work correctly: 2.6.29 2.6.29.6 2.6.30.4 2.6.31.9 Kernels 2.6.32 and 2.6.32.2 experience the disconnection I mentioned in the original post. Before checking 2.6.32, I have removed /lib/firmware/b43 completely and installed the firmware based on the detailed instructions on the web site. I also enabled CONFIG_B43_PHY_LP=y for 2.6.32. all kernels checked are vanilla kernels, from kernel.org. --y > On Sat, Dec 26, 2009 at 8:01 PM, <yha...@yhager.com> wrote: > > Hi, > > > > First, some adminstrativa.. > > > > $ uname -srvmip > > Linux 2.6.29 #4 Fri Aug 28 13:17:05 IDT 2009 i686 VIA C7-M Processor > > 1600MHz CentaurHauls > > > > $ lspci -vnn |grep 14e4 > > 02:00.0 Network controller [0280]: Broadcom Corporation BCM4312 > > 802.11a/b/g [14e4:4312] (rev 02) 07:03.0 Ethernet controller [0200]: > > Broadcom Corporation NetXtreme BCM5788 Gigabit Ethernet [14e4:169c] > > (rev 03) > > > > $ dmesg|grep b43-phy | head -1 > > [ 7.461364] b43-phy0: Broadcom 4311 WLAN found > > > > This same machine works fine when I use the 2.6.29 kernel, but when I > > use 2.6.32, I get "Carrier lost" disconnection after a couple of > > minutes (exact times vary between 30 seconds to about 2-3 minutes). > > > > Before filling everyone's inbox with large kernel logs, here's a > > snippet from dmesg: > > # dmesg | egrep "b43|wlan|AP" > > [ 0.000000] ACPI: APIC 6feb0390 00060 (v02 HP APIC2203 20080820 > > MSFT 00000097) [ 0.000000] #5 [0000008000 -
