wifi-menu dialog always results in CONNECTION FAILED

Hi guys,

I have a new Arch Linux installation on a HP ProBook 4540s. Upon installation, I have also run the following command:

pacman -S iw wpa_supplicant dialog

and all three packages were successfully installed.

A few days ago, I installed Virtual Box, and, my wifi connection broke. I have since removed Virtual Box in an attempt to restore my machine's ability to connect via wifi but that did not help.

Every time I connect using

wifi-menu

the result is CONNECTION FAILED.

May I please be assisted with this. I have tried

ip link set wlo1 down

and

ip link set wlo1 up

without any luck.

The following was return by iw wlo1 info:

Interface wlo1
    ifindex 3
    wdev 0x1
    addr 9c:d2:1e:1f:1f:27
    type managed
    wiphy 0

The following is returned when I type ip link:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp4s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 1000
    link/ether 9c:b6:54:20:4f:17 brd ff:ff:ff:ff:ff:ff
3: wlo1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000
    link/ether 9c:d2:1e:1f:1f:27 brd ff:ff:ff:ff:ff:ff

Re: wifi-menu dialog always results in CONNECTION FAILED

wifi-menu creates configuration files for netctl, what I am using. I'm not sure if these qualify for wpa_supplicant as well.

Try the following:
1.) switch to root
2.) set your interface up via

ip link set wlo1 up

3.) scan for networks via

iw dev wlo1 scan | grep SSID

and tell us if yours shows up

Re: wifi-menu dialog always results in CONNECTION FAILED

I noticed a change in DHCP behavior in more recent versions of Arch.  I'm not sure if this is related to your problem, but it is worth a shot.

I describe the situation I'm having here.

In the end I get my wifi working by utilizing the dhclient package.  I also required wpa_actiond for auto connection (these are already on the install media so you don't need it during that part):

pacman -S dhclient wpa_actiond

I then attempt a connection with wifi-menu and allow it to create a profile for the network even if it fails.  I can then modify the netctl profile under /etc/netctl by adding two lines:

ForceConnect=yes
DHCPClient="dhclient"

This allows me to connect to wifi via wifi-menu or netctl directly.  To automate the process I found that NetworkManager wouldn't work for me, so I used netctl auto connect instead:

systemctl enable netctl-auto@wlp61s0.service

You can obviously replace the wlp61s0 part with your wireless interface.

I'd be curious if this makes any impact in your situation.

Re: wifi-menu dialog always results in CONNECTION FAILED

As a sanity check, what are the output of:
ip link
uname -a
and
pacman -Qi linux    (Assuming you run the stock kernel.)

This is what shows up:

[goodman@localhost ~]$ su
Password: 
[root@localhost goodman]# ip link set wlo1 up
[root@localhost goodman]# iw dev wlo1 scan | grep SSID
	SSID: Spongebob

Spongebob is the network I am trying to connect to.

Re: wifi-menu dialog always results in CONNECTION FAILED

As a sanity check, what are the output of:
ip link
uname -a
and
pacman -Qi linux    (Assuming you run the stock kernel.)

This is the output of ip link:

[goodman@localhost ~]$ ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp4s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 1000
    link/ether 9c:b6:54:20:4f:17 brd ff:ff:ff:ff:ff:ff
3: wlo1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000
    link/ether 9c:d2:1e:1f:1f:27 brd ff:ff:ff:ff:ff:ff

The uname -a output is:

[goodman@localhost ~]$ uname -a
Linux localhost 4.6.2-1-ARCH #1 SMP PREEMPT Wed Jun 8 08:40:59 CEST 2016 x86_64 GNU/Linux

Re: wifi-menu dialog always results in CONNECTION FAILED

Thank you for your responses, guys. They lead me to this post here that solved my problem.

I disabled DHCPCD and set both enp4s0 (eth0) and wlo1 (wlan0) down, and then enabled and started Network Manager. I can now connect to Wi-Fi using the Network Manager applet.

Re: wifi-menu dialog always results in CONNECTION FAILED

Glad you got it solved.  Thanks for sharing your solution!

I'm pretty sure I ran those same steps and still had issues with NetworkManager, but I may try that out again in the future.  So far that auto connect is a nice light weight alternative for me.
