Broadcom BCM4312 rev 02 WiFi not recognised by Hardy
I have a Compaq 6715b laptop that I've been looking forward to running Ubuntu on. With the release of Hardy Heron (8.04) I thought I would give it another go. The only issue I have is the wireless card, which is a Broadcom BCM4312 rev 02 PCI device. Output of lspci -v is below:
30:00.0 Network controller: Broadcom Corporation BCM4312 802.11a/b/g (rev 02)
Subsystem: Hewlett-Packard Company Unknown device 1371
Flags: bus master, fast devsel, latency 0, IRQ 18
Memory at c8000000 (64-bit, non-prefetchable) [size=16K]
Capabilities: [40] Power Management version 3
Capabilities: [58] Vendor Specific Information
Capabilities: [e8] Message Signalled Interrupts: Mask- 64bit+ Queue=0/0 Enable-
Capabilities: [d0] Express Endpoint IRQ 0
I've installed the b43-fwcutter package to download and extract the appropriate firmware for my device. However, when I modprobe b43 nothing gets written to either dmesg output or /var/log/syslog. No new Ethernet devices appear and Network Manager cannot see a wireless card.
This appears to be a detection issue with the 2.6.24 kernel which Hardy is running. A patch is available at http://
Thanks in advance,
Ian.
