Problems setting up bcm43xx

[Joerg Sommer <joerg@alea.gnuu.de>]

Hi,

next try, one level lower. I try to configure my airport extreme with the
following section in /etc/network/interfaces:
iface wlanhome inet static
	address 192.168.0.5
	netmask 255.255.255.255
	pointopoint 192.168.0.8
	wireless_essid home
	wireless_channel 2
	wireless_mode ad-hoc

After bringing up the interface with ifup I get the status no carrier.

# ip link list dev eth1
5: eth1: <BROADCAST,MULTICAST> mtu 1500 qdisc pfifo_fast qlen 1000
    link/ether 00:11:24:90:ca:3b brd ff:ff:ff:ff:ff:ff
# ifup eth1=wlanhome
# ip link list dev eth1
5: eth1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000
    link/ether 00:11:24:90:ca:3b brd ff:ff:ff:ff:ff:ff
# iwconfig eth1
eth1      IEEE 802.11b/g  ESSID:"home"  Nickname:"Broadcom 4306"
          Mode:Ad-Hoc  Frequency=2.417 GHz  Cell: Invalid   
          Bit Rate:54 Mb/s   Tx-Power=2346 dBm   
          RTS thr:off   Fragment thr:off
          Encryption key:off

What's wrong? I use the current version in Debian of the softmac and the
bcm43xx driver

$ dpkg -l ieee80211softmac-modules-2.6.15.1 bcm43xx-modules-2.6.15.1 |grep ^ii
ii  bcm43xx-modules-2.6.15.1          20060108-5+ibook.33 Broadcom 43xx Wireless LAN driver module for Linux 2.6.15.1
ii  ieee80211softmac-modules-2.6.15.1 20060114-4+ibook.32 IEEE 802.11 SoftMAC kernel module for Linux 2.6.15.1

What should I do?

Good night, Jörg.
