Hi, I'm using notebook Acer Aspire 5022 with builtin WLAN Broadcom 4318.
>>>
[EMAIL PROTECTED] ~]# lspci -v

06:05.0 Network controller: Broadcom Corporation BCM4318 [AirForce One 54g]
802.11g Wireless LAN Controller (rev 02)

My wlan worked well until I upgraded from fedora core 6 to fedora 7. Then
bcm43xx-Driver complaints about old firmware version, so I have to get
newer driver. I downloaded broadcom-wl-4.80.53.0.tar.bz2 from
http://downloads.openwrt.org/sources/ and then use bcm43xx-fwcutter which
has following version:
>>>
[EMAIL PROTECTED] bcm43xx]# rpm -q bcm43xx-fwcutter
bcm43xx-fwcutter-006-1.fc7.x86_64
<<<
Until here it seems to be ok, but the fwcutter warns me, because I use the
new driver (4.xx). I think its ok.
Following command shows you, what dmesg says after booting (the modules
seems to be loaded automatically):
>>>
[EMAIL PROTECTED] ~]# dmesg | grep bcm
bcm43xx_mac80211: Broadcom 4318 WLAN found
bcm43xx_mac80211: Found PHY: Analog 3, Type 2, Revision 7
bcm43xx_mac80211: Found Radio: Manuf 0x17F, Version 0x2050, Revision 8
bcm43xx_mac80211: Radio turned off
[EMAIL PROTECTED] ~]# lsmod | grep bcm

ssb 43589 1 bcm43xx_mac80211
mac80211 164297 2 rc80211_simple,bcm43xx_mac80211
<<<
Now let try to use wlan. First I have to turn on wlan since the wlan-button
isn't working under linux:
>>>
[EMAIL PROTECTED] ~]# modprobe acer_acpi
[EMAIL PROTECTED] ~]# echo "enabled : 1" > /proc/acpi/acer/wireless
[EMAIL PROTECTED] ~]# dmesg
[snip]
acer_acpi: Acer Laptop ACPI Extras version 0.5
acer_acpi: Wireless value 0
acer_acpi: Wireless value 1
<<<
After enabling wlan with the command 'echo > wireless' the last line in
dmesg appears.
First I check if there is a device wlan0:
>>>
[EMAIL PROTECTED] ~]# iwconfig wlan0
wlan0 IEEE 802.11g ESSID:""
Mode:Managed Channel:0 Access Point: Not-Associated
Retry min limit:7 RTS thr:off Fragment thr=2346 B
Encryption key:off
Link Quality:0 Signal level:0 Noise level:0
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0
<<<
Now try to get up wlan0 and try to get ip-through dhcp (I already tried with
fixed IP at home, but no success :( ):
>>>
[EMAIL PROTECTED] ~]# ifup wlan0
Determining IP information for wlan0... failed.
<<<
At least the wlan-LED was blinking slowly. now let look into dmesg again:
>>>
[EMAIL PROTECTED] ~]# dmesg
[snip]

<<<
There is a warning line, which may be the cause of nonworking. :(
If I look into iwconfig it shows Link-Quality, Signal- and Noise-level. Does
it sound good?
>>>
[EMAIL PROTECTED] ~]# iwconfig
lo no wireless extensions.
wmaster0 no wireless extensions.

But wait, what the hell is wmaster0? In FC6 there was no wmaster0! Whatever.
Now look again into ifconfig. You can see that some bytes was sent/received
(I think it's from trying getting IP-Adress from dhcp-server):
>>>
[EMAIL PROTECTED] ~]# ifconfig wlan0
wlan0 Link encap:Ethernet HWaddr XX:XX:XX:XX:XX:XX
UP BROADCAST MULTICAST MTU:1500 Metric:1

collisions:0 txqueuelen:1000
RX bytes:346 (346.0 b) TX bytes:8657 (8.4 KiB)
<<<
If I try with 'iwlist scan' the AccessPoints are shown in wlan0 which looks
very good. So where is a problem? I hope someone of you could help me.
Please!

PS: With the newer version of bcm43xx there is no need to 'modprobe bcm43xx'
(I mean 'bcm43xx' not 'bcm43xx_mac80211'), am I right?
PS2: I've tried with Windows-Vista-driver for broadcom-chip, but
unfortunatelly it's too new for fwcutter. :(
