 |
|
Hi,
I have a laptop with 2 linux installations. Ubuntu and Gentoo. With ubuntu I can make my wireless card work.
With ubuntu the configuration wad reletively easy. That's the file I had in my ubuntu box under /etc/network/interfaces:
| Quote: |
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
iface eth1 inet static
address 192.168.1.3
netmask 255.255.255.0
gateway 192.168.1.1
#wireless
auto eth0
iface eth0 inet dhcp
netmask 255.255.255.0
gateway 192.168.1.1
wpa-driver wext
wpa-conf managed
wpa-ssid MYSSID
wpa-ap-scan 1
wpa-proto WPA
wpa-pairwise TKIP
wpa-group TKIP
wpa-key-mgmt WPA-PSK
wpa-psk thekeygeneratedwith_wpa_passphrase
|
Under ubuntu by issuing /etc/init.d/networking restart I could have wireless and wired working.
I have a Broadcom wireless card. From lspci: | Quote: |
06:05.0 Network controller: Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller (rev 02) |
Now, coming back to Gentoo...
I followed this Gentoo Wireless Networking Howto. I've created a symbolic link called /etc/init.d/net.wlan0; I've installed ndiswrapper.
My /etc/conf.d/net looks like this:
| Quote: |
config_eth0=( "192.168.1.3 netmask 255.255.255.0 brd 192.168.1.255" )
#config_eth0=( "dhcp" )
routes_eth0=( "default gw 192.168.1.1" )
iwconfig_eth0="mode managed"
modules=( "wpa_supplicant" )
#wpa_supplicant_wlan0="-Dndiswrapper"
wpa_supplicant_wlan0="-Dwext"
config_wlan0=( "dhcp" )
#config_wlan0=( "192.168.1.4 netmask 255.255.255.0 brd 192.168.1.255" )
routes_wlan0=( "default gw 192.168.1.1" )
|
My /etc/wpa_supplicant.conf looks like this:
| Quote: |
# The below line not be changed otherwise we refuse to work
ctrl_interface=/var/run/wpa_supplicant
# Ensure that only root can read the WPA configuration
ctrl_interface_group=0
# Let wpa_supplicant take care of scanning and AP selection
ap_scan=1
# poli network
network={
ssid="MYSSID"
key_mgmt=WPA-PSK
proto=WPA
pairwise=TKIP
group=TKIP
psk=hekeygeneratedwith_wpa_passphrase
# The higher the priority the sooner we are matched
priority=5
}
|
If I do /etc/init.d/net.wlan0 restart I get this:
| Quote: |
* Stopping wlan0
* Bringing down wlan0
* Shutting down wlan0 ... [ ok ]
* Stopping wpa_cli on wlan0 ... [ ok ]
* Stopping wpa_supplicant on wlan0 ... [ ok ]
* Starting wlan0
* Starting wpa_supplicant on wlan0 ... [ ok ]
* Starting wpa_cli on wlan0 ... [ ok ]
* Backgrounding ...
|
and finally if I do ifconfig:
| Quote: |
eth0 Link encap:Ethernet HWaddr 00:0A:E4:F4:47:F9

Of course wireless doesn't work, else I wouldn't be here.
What's wrong in my configuration? How can I get it working considering that under Ubuntu it works with the configuration mentioned above?
Thanks to enlighten me |

Maybe wlan0 isn't coming up because eth0 is up.
What happens when you do this:
| Code: | ifconfig eth0 down
ifconfig wlan0 up
dhcpd wlan0 |
(One of the last two commands may be redundant, or they might be better switched)
I don't know how to make this a permanent thing, without disabling eth0, which you don't want, right. Giving eth0 a static address might be the problem, if it were dhcp then it wouldn't come up, so wlan0 would take over.
If that doesn't work, what is the output of
Are you connected? |

Did you mean: iwconfig_wlan0="mode managed"

iwconfig is like ifconfig, but is meant for use with wireless network adapters and gives you more information about wireless connections, specifically it will tell you if a connection has been established with your access point - you can have an established connection without having an IP address assigned.
It seems that iwconfig is in the wireless-tools ebuild. Is this installed?
As you can see from the man page iwconfig on its own will list all adapters and show any wireless attributes, I think this would include a list of available networks, if the adapter did not have an established connection.
Did you try the 'eth0 down, wlan0 up' thing? |

| Maybe I should have mentioned that you will have to run iwconfig as root. It will not be seen by a normal user. |

Thanks for your answers guys.
Chris W: yep I meant iwconfig_wlan0="mode managed"
bernied: dhcpd doesn't work to me, i didnt configure /etc/dhcp/dhcpd.conf ... i use dhclient instead...
i stopped eth0 and did: ifconfig wlan0 up; dhclient wlan0
i get this:

How can I verify if I'm connected to the wireless router?
I tried to use also a static configuration:
| Quote: |
modules=( "wpa_supplicant" )
wpa_supplicant_wlan0="-Dwext"
#config_wlan0=( "dhcp" )
config_wlan0=( "192.168.1.4 netmask 255.255.255.0 brd 192.168.1.255" )
routes_wlan0=( "default gw 192.168.1.1" )
|
it still doesn't work.
By the way, please note that my wireless access point has this IP: 192.168.1.10
But the default gateway of my network is a wired zyxel router, with IP 192.168.1.1 and DHCP enabled...
I repeat, from ubuntu it works, I will check under ubuntu what I get with iwconfig and which one is the default route...
Thanks for helping, I really want to solve this. |

I don't know why but i have the impression that there is a problem selecting my AP, but I've checked the SSID name is correct.
Under ubuntu this line shows MYSSID instead of "Not-Associated" if I do iwconfig:
| Quote: | | Mode:Managed Frequency:2.462 GHz Access Point: Not-Associated |
I don't know... really, I'm getting crazy because of this. |

You could try manually configuring the interface and then checking that it is working in gross terms: | Code: | ... config interface stuff...
ifconfig wlan0 up
iwlist wlan0 scan
ifconfig wlan0 down |
(you should see your AP) then running wpa_supplicant with debug output: | Code: | | wpa_supplicant -dd -D wext -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf 2>&1 | tee wpa_supplicant.log |
One thing to look out for is how you have entered the key in the config file; quotes around string keys, and no quotes if the key is a hex string.

thanks Chris W... if I do modprobe ndiswrapper, the interface is up (no need to to ifconfig wlan0 up); next step:
| Quote: | iwlist wlan0 scan
wlan0 Scan completed :
Cell 01 - Address: APMACADDRESS
ESSID:"MYSSID"
Protocol:IEEE 802.11g
Mode:Managed
Frequency:2.462 GHz (Channel 11)
Quality:100/100 Signal level:-31 dBm Noise level:-96 dBm
Encryption key:on
Bit Rates:1 Mb/s; 2 Mb/s; 5.5 Mb/s; 11 Mb/s; 6 Mb/s
9 Mb/s; 12 Mb/s; 18 Mb/s; 24 Mb/s; 36 Mb/s
48 Mb/s; 54 Mb/s
Extra:bcn_int=100
Extra:atim=0
IE: WPA Version 1
Group Cipher : WEP-40
Pairwise Ciphers (1) : WEP-40
Authentication Suites (1) : PSK |
in my wpa_supplicant.conf I configured pairwise and group to be TKIP, could this be the problem? With the scanning I see WEP-40... I will try to change these parameters and let you know...
| Quote: | | One thing to look out for is how you have entered the key in the config file; quotes around string keys, and no quotes if the key is a hex string. |
I entered the hex key without doublequotes (")... |

Excellent, the card is working. | firepol wrote: | ...

TKIP is a layer on top of the same encryption system used in WEP (constantly changing the keys). I don't think this is the issue. You could grab a copy of the wpa_supplicant.conf that Ubuntu writes on your behalf, but I'm fairly sure you'll find that it lists TKIP too.
I think the debug output from wpa_supplicant (see my last post) will be more diagnostic.

This might help: I have wpa_supplicant on my wired (eth0) and wireless (eth1) interfaces, and both automatically acquire IP's. Posting configs:
/etc/conf.d/net
| Code: | modules_eth0=( "wpa_supplicant" )
wpa_supplicant_eth0="-D wired"
wpa_timeout_eth0=60
config_eth0=( "dhcp" )
dhcp_eth0="-t 10"
modules_eth1=( "wpa_supplicant" )
wpa_supplicant_eth1="-D wext"
wpa_timeout_eth1=60
config_eth1=( "dhcp" )
dhcp_eth1="-t 10" |
/etc/wpa_supplicant/wpa_supplicant-eth0.conf
| Code: | ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=users
ap_scan=0
# Connect to anything unsecured ... Wired, remember?
network={
ssid=""
scan_ssid=1
key_mgmt=NONE
priority=-999999
} |
/etc/wpa_supplicant/wpa_supplicant-eth1.conf
| Code: | ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=users
ap_scan=1
network={
ssid="ElsayedHome"
scan_ssid=1
key_mgmt=WPA-PSK
pairwise=TKIP
psk="my_secret_psk"
}
network={
ssid="marlinspike"
scan_ssid=1
key_mgmt=WPA-PSK
psk="my_friend's_secret_psk"
} |
Try those settings, from /etc/conf.d/net and eth1, and see if it works.
The only quirk I've had is that if wireless and wired are both started, you're connected to wireless, and you plug in ethernet, the disconnect it you have to stop eth0 before any apps'll use the right interface.
