netcfg fails on boot, but works if restarted

https://bbs.archlinux.org – netcfg used to work fine, but now I have to reconnect after a fresh boot.$ netcfg -r wlan0 > Profile not connected :: wlan0 up [BUSY] ctrl_iface exists and seems to be in use - cannot override it Delete '/run/wpa_supplicant/wlan0' manually if it is not used anymore Failed to initialize control interface '/run/wpa_supplicant'. You may have another wpa_supplicant process already running or the file was left by an unclean termination of wpa_supplicant in which case you will need to manually rem (HowTos)

Stories similar to netcfg fails on boot, but works if restarted

I'm having a recurrent issue with my Arch Linux installation: wireless will work for a few minutes and then randomly die.

Hi there,I'm trying to start wpa_supplicant automatically when starting multi-user.target without going through something fancy like netcfg or NetworkManager. So I have done systemctl enable wpa_supplicant@wlan0Unforutnately, this doesn't work.

Hi,I read the sources of netcfg, and there’s something I didn’t get. Why wpa_supplicant is always used even to join wep network? Isn’t it confusing?EDIT: here’s a line to prove my sayinghttps://projects.archlinux.org/netcfg.g … reless#n19

I've been using a minimal setup a friend handed to me:~/bin/wifi#! /bin/bash

if [[ -n $(ls /var/run/wpa_supplicant 2>/dev/null) ]]; then echo "Already connected" else sudo wpa_supplicant -B -Dwext -c /etc/wpa_supplicant/wpa_supplicant.conf -i wlan0 sudo wpa_cli -B -a /home/maca/bin/wpa_cli-action fi ~/bin/wpa_cli-action#!

Hi all

If i associate to an Access Point with

Code: wpa_supplicant -B -Dwext -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf What's the opposite command to cleanly disassociate?

Thanks.

I am running Ubuntu Server 12.04. I have a wireless USB card. When I begin the boot process I see:

Waiting for network configuration

It turns out that the network never comes up. But once I get to the command line, if I type: ifup wlan0, then I have network access.

Every so often when I boot my notebook, and initiate the network connection like so:sudo ip link set wlan0 up sudo wpa_supplicant -B -i wlan0 -Dwext -c /etc/wpa_supplicant.confwait for ten secondssudo dhcpcd wlan0dhcpcd polls, then connects fine.  But, after about 10-20 seconds, the connection drops.  10-20 seconds later, it's back up.  This becomes apparent when I ping a site,

You could try the following, which solved a possibly similar problem with a JME card:ip link set dev wlan0 down ip link set dev wlan0 promisc on macchanger -a wlan0 ip link set dev wlan0 upThen reconnect with wpa_supplicant or whatever you use.

This question will probably be moot, since I'll only be here one more day.
