 Posted: Fri Feb 12, 2010 11:24 pm Post subject: [solved]Networkmanager ruined my wireless config |
 |
|
Hi
I had a working Wireless configuration based on wpa_supplicant.
Then i wanted to try out NetworkManager. I followed the instructions in
the NetworkManager HowTo http://www.gentoo-wiki.info/HOWTO_NetworkManager
After this i was still able to use the wired connection, but NetworkManager-applet
didn't see any wireless connections.
So i unmerged NetworkManager again and reinstated net.eth0, but now i can't get
the wireless running any more, even though i didn't touch any of the configuration files
(with the exception of /etc/conf.d/net, which i restored to its original contents).
The wireless networks are detected but wlan0 claims not having a key set | Code: | * Starting wlan0
* Configuring wireless network for wlan0
* WEP key is not set for "idastrasse" - not connecting
* WEP key is not set for "ykr-43539" - not connecting
* WEP key is not set for "strada lunga" - not connecting
* Couldn't associate with any access points on wlan0
* Failed to configure wireless for wlan0 [ !! ]
wlan0: dhcpcd not running
wlan0: dhcpcd 4.0.15 starting
wlan0: waiting for carrier
wlan0: timed out
|
But in my /etc/wpasupplicant/wpasupplicant.conf i have this info | Code: | ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
ap_scan=1
network={
ssid="idastrasse"
psk="my_key"
priority=5
} |
A further annoyment is that when i try to start the wlan, my resolv.conf
gets overwritten like this | Code: | # Generated by resolvconf
search magnus
|
I have put a USE flag 'resolvconf' into my make.conf when emerging NetworkManager,
so i suspect this resolvconf has been installed together with NetworkManager.
So i unmerged NetworkManager and reemerged 'world' with --deep --newuse after this.
But somehow there still seems to be a resolvconf around:
I am dependent on having particular nameservers in there,
which should not be overwritten, or else firefox can't resolve names (cf. https://forums.gentoo.org/viewtopic-t-811912.html)
To ensure that dhcp does not overwrite this, i have made 'nodns'-entries in my /etc/conf.d/net: | Code: | config_eth0=( "dhcp" )
wpa_supplicant_eth0="-Dwext"
# blacklist 'bad' adresses
dhcpcd_wlan0="-X 192.168.77.1 -X 192.168.0.1"
dns_domain_lo="magnus"
dhcp_eth0="nodns"
dhcp_wlan0="nodns"
dhcp_lo="nodns" |
Does anybody have any suggestion how i can get my wireless running again (and perhaps get rid of resolvconf in safe way)?
Thank You
Jody

Hello. Do you have 'modules=( "wpa_supplicant" )' in your /etc/conf.d/net ?
About that file.. you can just run 'equery belongs' from gentoolkit. |

Hi patrikas
Thank You for your reply.
| Quote: | | Do you have 'modules=( "wpa_supplicant" )' in your /etc/conf.d/net ? |
This line was missing (but i don't remember taking it out - and it did work before...)
Anyway, i put it in and wlan0 comes up alright, but now it ignores the "nodns" setting
in my /etc/conf.d/net: | Code: | enki jody # 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 :]!).
config_eth0=( "dhcp" )
modules=( "wpa_supplicant" )
wpa_supplicant_eth0="-Dwext"
dhcpcd_wlan0="-X 192.168.77.1 -X 192.168.0.1"
dns_domain_lo="magnus"
dhcp_eth0="nodns"
dhcp_wlan0="nodns"
dhcp_lo="nodns"
|
Any idea why this might be so?
Thank You
Jody |

Hi,
You might need 'config_wlan0=( "dhcp" )' too. See /etc/conf.d/net.example for more details. Have you deleted resolv.conf ? |
