[问题]求助 8.04LTS 无线问题

[Atherod]

本本 DELL D630 ，有线是eth0，无线是wlan0，硬件DELL 1390（就是BCM的43XX？），无线配置无法保存，驱动用自带的，每次重新启动以后进入系统都要重新来一遍
sudo iwconfig wlan0 essid SSID
sudo iwconfig wlan0 key "s=PASSWD"
sudo /etc/init.d/networking restart
才能联上我的AP。。。
郁闷的很各位大大帮帮忙哇～～～
谢谢拉～

发现一个问题，芯片bcm4311,我不知道怎么搞的装了2个驱动！？
lspci列出：
*-network
description: Network controller
product: BCM94311MCG wlan mini-PCI
vendor: Broadcom Corporation
physical id: 0
bus info: pci@0000:0c:00.0
version: 01
width: 32 bits
clock: 33MHz
capabilities: bus_master cap_list
configuration: driver=b43-pci-bridge latency=0 module=ssb
*-network
description: Wireless interface
physical id: 1
logical name: wlan0
serial: 00:1d:d9:6c:e8:af
capabilities: ethernet physical wireless
configuration: broadcast=yes ip=192.168.0.4 multicast=yes wireless=IEEE 8
看的出下面这个是实际在用的，请问如何删除？
network-manager控制自带的受限驱动，应该是上面那个，用network-manager配置不成功
有人可以帮忙么?感激！
