 Posted: Sun Jul 18, 2010 6:41 pm Post subject: std wireless setup [self solved] |
 |
|
This is my first ever post in this sub forum. I thought my wired network card developed a fault, but it in fact is not.
So I still have eth0 to plug into the network, but I spent half the day trying to get the wireless network card configured.
Having started this, I would rather like the wireless card to work as it did in the gentoo of the past.
I first did this about 2 -3 years ago without a problem. I found a gentoo wiki doc that outlined it using wpa_supplicant, so I did it all again.
It just doesn't work. I followed the wiki instructions.
I happen to have another post in another forum and from that post I got some instructions on hos to get it to connect.
These instructions were intended for the other distro, but the wpa_supplicant package isn't gentoo specific so I ran it in gentoo.
It half works, actually making a connection, but it's in a constant state of flux.
First, the /etc/conf.d/net which is slightly edited but follows the lead from the gentoo wiki.
| Code: |
idella@genny ~ $ cat /etc/conf.d/net
# This blank configuration will automatically use DHCP for any net.*
# scripts in /etc/init.d. To create a more complete configuration,
# please review /etc/conf.d/net.example and save your configuration
# in /etc/conf.d/net (this file :]!).
dns_domain_lo=homenetwork
config_wlan0=( "dhcp" )
bridge_virbr0="eth0"
config_virbr0=("dhcp")
#config_eth0=("null")
##config_eth0=( "dhcp" )
#bridge_br0="eth0"
#config_br0=("dhcp")
#
#config_eth0=("null")
# Prefer wpa_supplicant over wireless-tools
modules=( "wpa_supplicant" )
# It's important that we tell wpa_supplicant which driver we should
# be using as it's not very good at guessing yet
wpa_supplicant_wlan0="-Dmadwifi"
#wpa_supplicant_wlan0="ath_pci"
#iwconfig_wlan0="mode managed"
|
Now the wiki cites wpa_supplicant_wlan0 as wpa_supplicant_eth0, which is odd. eth0 is the interface for a wired network card.
The only other config required is for /etc/wpa_supplicant/wpa_supplicant.conf;
| Code: |
idella@genny ~ $ cat /etc/wpa_supplicant/wpa_supplicant.conf
# 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
# Only WPA-PSK is used. Any valid cipher combination is accepted
network={
ssid="delaney"
scan_ssid=1
proto=WPA
key_mgmt=WPA-PSK
pairwise=CCMP TKIP
# group=CCMP TKIP WEP104 WEP40
psk="e235485512"
priority=5
}
|
If I'm unclear about anything it's WPA bs WEP.
The wireless network card passphrase is in fact a WPA type, so there should not be a problem.
It has major hassles with the scanning. dmesg is really helpful.
| Code: |
idella@genny ~ $ sudo grep wlan0 /var/log/dmesg
Password:
|
Nothing. There is a little gui tool that has turned up called wpa_gui. It's utterly impotent.
It lists nothing present. Tell it to scan and it doesn't. It connects to nothing.
Now, here are the steps I was given that managed to kickstart it once.
| Quote: |
Say my network is called scott and my password is toracat. (It's late, I don't feel creative) 
(This part can be done as normal user)
wpa_passwd scott toracat > wpa.conf
This creates a file called wpa.conf that will look like [Gentoo's wpa_supplicant doesn't have wpa_passwd]
network={
ssid="scott"
#psk="toracat"
psk=69e49214ef4e7e23d0ece077c2faf3c73f7522ad52a26b33527fa78d9033ff35
}
Now, as I'm lazy, and my router came with wireless network hidden by default, I also have to insert a line telling it to scan. So, now it will look like.
network={
scan_ssid=1
ssid="scott"
#psk="toracat"
psk=69e49214ef4e7e23d0ece077c2faf3c73f7522ad52a26b33527fa78d9033ff35
}
Ok, now I bring up the wireless card. It might be up, but this won't affect anything.
The rest of this has to be done as root or with root privilege.
ifconfig wlan0 up
Now I test it
iwlist wlan0 scan
Hopefully, I see a list of networks.
Now, I run wpa_supplicant to see if it will connect
I'm still in the directory containing that wpa.conf file
wpa_supplicant -Dwext -iwlan0 -cwpa.conf
With luck it connects. Then I run
dhclient wlan0
have an address and all is good.
If that all works, now I do
cp wpa.conf /etc/wpa_supplicant/wpa_supplicant.conf
I also edit as described in the link in my earlier post
|
idella@genny ~ $ ls /etc/sysconfig/wpa_supplicant
This is centos specific.
So,
| Code: |
idella@genny ~ $ sudo ifconfig wlan0 up

This time it doesn't help. Fails all round. What is wrong? It looks to me the kernel isn't quite right.
Can't ignore this
ioctl[SIOCSIWENCODEEXT]: No such file or directory
what it it???
ok, an edit. I adjusted /etc/conf.d/net to
| Code: |
dns_domain_lo=homenetwork
config_wlan0=("dhcp")
config_eth0=("dhcp")
bridge_virbr0="eth0"
config_virbr0=("dhcp")
#config_eth0=("null")
##config_eth0=( "dhcp" )
#bridge_br0="eth0"
#config_br0=("dhcp")
#
#config_eth0=("null")
# Prefer wpa_supplicant over wireless-tools
modules=( "wpa_supplicant" )
# It's important that we tell wpa_supplicant which driver we should
# be using as it's not very good at guessing yet
#wpa_supplicant_wlan0="-Dmadwifi"
wpa_supplicant_wlan0="ath5k"
iwconfig_wlan0="mode managed"
|
The madwifi driver is actually ath_pci. The kernel provides an atheros driver ath5k. They both in fact work. the line
wpa_supplicant_wlan0="-Dmadwifi"
puzzles me. -Dmadwifi must be some generis term that refers to atheros drivers,
so I replaced it for row with the actual driver from the kernel ath5k. This ath5k is employed by suse and works properly.

This leaves idella@genny ~ $ sudo wpa_supplicant -Dwext -iwlan0 -c/etc/wpa_supplicant/wpa_supplicant.conf
stuck in an endless loop which is wrong. I would like to be able to exlcude eth0 from boot and have
the gentoo scripts and wpa_supplicant bring up wlan0 in the gentoo way.

normally I edit my post rather than answer it, but this qualifies.
BTW thanks for your help
this google search lead to this post and and this post and this bug which lead to emerging updating openrc.
