Comment 2 for bug 153358

I have the same problem. I tried both amd64 and i386 versions of gutsy and used bcm43xx-fwcutter (through restricted-manager) to get the firmware. My computer is HP notebook (dv6510ew). In fwcutter I used the firmware from internet link that was provided. I also tried several other firmwares (like this: http://downloads.openwrt.org/sources/wl_apsta-3.130.20.0.o from http://linuxwireless.org/en/users/Drivers/b43 and bcm43xx_compwiz18.1-all.deb firmware (got it somewhere on forum)) with the same result. I also tried extracting firmware from windows vista driver (bcmwl6.sys) but fwcutter told me that this file doesn't contain any firmware.

I don't know what the problem may be, because the card is listed as compatibile with the bcm43xx driver. So maybe firmware is incorrect, if so restricted-manager should check it and point proper firmware to me.

With these errors card is listed in iwconfig but can't find any network (and network is present because on windows it gets detected with about 80% strenght).

This is lspci outpu about my card:

03:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11a/b/g [14e4:4312] (rev 02)

 Flags: bus master, fast devsel, latency 0, IRQ 16
 Memory at b0200000 (64-bit, non-prefetchable) [size=16K]

Dmesg output about wifi card is exactly the same as in reporter's attachment.
