HP6720s Broadcom 4312


I'm trying to configure wireless on the setup above.

Lspci reports the following:

10:00.0 Network controller: Broadcom Corporation BCM4312 802.11a/b/g (rev 02)
10:00.0 0280: 14e4:4312 (rev 02)

I'm running Slackware current kernel version 12.1 2.6.24.4-smp i686

I've followed the instructions on http://linuxwireless.org/ and used b43 cutter to install firnware for the card. I'm currently trying to get a connection without security before I try and implement security. I can't get a response from http://linuxwireless.org/ at the minute, but I vaguely recall seeing that the 4312 wasn't supported, but I've had some limited success so it may be. I know it can be done with ndiswrapper too, and that may be my next step.

Anyway, as I've mentioned, I think I have some limited success.

If bring up wlan0, ifconfig reports this:

lo Link encap:Local Loopback

and iwlist scan reports this:

which correctly reports my wireless access point as Cell01, and I guess a neighbour's as cell2. I've removed anything that can used to identify. This seems to show it's working to an extent and from this point I don't know whether it's a networking or wireless issue.

I've edited rc.inet1.conf

Example config information for wlan0. Uncomment the lines you need and fill
## in your info. (You may not need all of these for your wireless network)
IFNAME[4]="wlan0"
IPADDR[4]=""
#NETMASK[4]=""
USE_DHCP[4]="yes"
DHCP_HOSTNAME[4]="Pscylo"
#DHCP_KEEPRESOLV[4]="yes"
#DHCP_KEEPNTP[4]="yes"
#DHCP_KEEPGW[4]="yes"
#DHCP_IPADDR[4]=""
WLAN_ESSID[4]=******
WLAN_MODE[4]=Managed
##WLAN_RATE[4]="54M auto"
WLAN_CHANNEL[4]="5"
##WLAN_KEY[4]="D5AD1F04ACF048EC2D0B1C80C7"
##WLAN_IWPRIV[4]="AuthMode=WPAPSK EncrypType=TKIP WPAPSK=7B1ABEEB5D197741923ED26727569C365E31212096A0EAFAD563B268BAD01CAF TxRate=0"
#WLAN_WPA[4]="wpa_supplicant"
#WLAN_WPADRIVER[4]="ndiswrapper"

and on startup, it says something about polling for an IP address at which point it says no carrier detected and consequently no connection is made.

I don't know whether I've set the network up wrong, or if it is the card.

If anyone can point me in the right direction even to the point that you can tell me what files I need to look in to troubleshoot I will be extremely grateful. I would post the messages I get on startup, but I don't know where I would find the output. I'm not quite a newby, but I'm still finding my feet a bit.
