 |
|
Hi
I had so much problems with this card on my laptop (HP Pavilion dv5000 with AMD Turion64 (so HowTo is for x86_64 system, I dont try on x86)) and I know, that often many people have this same problem like me, so I wrote this short and simply (I think so) HowTo (It's translate from my oryginal HowTo in polish language).
So, let's start!
Firstly we have to have a kernel from 2.6.18 series, because on 2.6.19* sometimes are problems with ndiswrapper like this what I had - bugs.gentoo.org
We go into /usr/src/kernel_sources and do make menuconfig and we have to disable drivers for broadcom, so go to
| Code: |
Device Drivers -> Network Device Support -> Wireless LAN (non-hamradio) -> < > Broadcom BCM43xx wireless support
|
and turn off drivers.
Recompile and reboot for new kernel without drivers.
Now - ndiswrapper
Now we must download drivers for ndiswrapper:
ftp://ftp.support.acer-euro.com/notebook/aspire_3020_5020/driver/winxp64bit/80211g.zip
or
http://adyton.com.pl/~poe/files/80211g.zip
and unpack it and go to unpacked directory (80211g)
Now we should remove standard drivers form ndiswrapper:
| Code: |
#ndiswrapper -l
driver_name#1
driver_name#2
#ndiswrapper -r driver_name#1
#ndiswrapper -r driver_name#2
|
and install new (these downloaded)
| Code: |
#ndiswrapper -i bcmwl5.inf
|
After correct install we have to edit a file [/i]/etc/modules.autoload.d/kernel-2.6[/i] and add to list ndiswrapper module manualy or
| Code: |
#echo "ndiswrapper" >> /etc/modules.autoload.d/kernel-2.6
|
Now we should reboot a computer for reload a kernel and update a modules (on my machine I had to reboot, because modprobe ndiswrapper + modules-update didnt give me positive results) and after reboot we going to emerge wireless-tools
| Code: |
#emerge wireless-tools
|
and when compile is done then we start iwconfig. We should see wlan0 interface.
Ok. Now we'll be configure WPA encryption.
Firstly we have to compile wpa_supplicant
| Code: |
emerge wpa_supplicant
|
and configure:
1) wpa_passphrase
| Code: |
#wpa_passphrase <SSID> <WPA-KEY>
|
This program will generate long string. Copy it.
Secondly we're editing /etc/wpa_supplicant/wpa_supplicant.conf (IMPORTANT: Sometimes this file should be in /etc, not in /etc/wpa_supplicant)
The simply config should look like this
| Code: |
network={
ssid="OWN_SSID"
key_mgmt=WPA-PSK
psk=THERE_WE_PAST_GENERATED_STRING_BY_WPA_PASSPHRASE
}
|
Sometimes must run command
| Code: |
#wpa_supplicant -Dwext -iwlan0 -c/etc/wpa_supplicant/wpa_supplicant.conf
|
And last - /etc/conf.d/net file:
| Code: |
#wlan0
modules_wlan0=( "wpa_supplicant" )
wpa_supplicant_wlan0="-Dwext"
config_wlan0=( "192.168.x.x netmask 255.255.255.0 brd 192.168.x.x" )
routes_wlan0=( "default gw 192.168.x.x" )
|
If You use dhcp then config_wlan0 and routes_wlan0 should be change to dhcp lines like in wired interfaces (ethX)
We're cerating symlink now in /etc/init.d from net.wlan0 => net.lo
and start!
| Code: |
#/etc/init.d/net.wlan0 start
|
If all was correct, we should see iwconfig similar like this
| Code: |
wlan0 IEEE 802.11g ESSID:"OWN_SSID"
Mode:Managed Frequency:2.422 GHz Access Point: MAC_OR_NAME_OF_AP
Bit Rate=36 Mb/s Tx-Power:24 dBm
RTS thr:2347 B Fragment thr:2346 B
Encryption key:************** Security mode:restricted
Power Management:off
Link Quality:51/100 Signal level:-63 dBm Noise level:-96 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:12810 Invalid misc:42495 Missed beacon:0
|
That's all 
IMPORTANT: Sometimes You could havent a connection, then You have to stop a wired connections (ethX)
| Code: |
#/etc/init.d/net.eth* stop
|
IMPORTANT: HowTo is for x86_64 systems
So, have a great fun without cabels
cheers & sorry for my english
