Wi-Fi disconnected unexpectendly - can't use one netctl profile anymor

balance · 2017-11-01 15:02:45

Hi,

so I have several netctl profiles and I also used the netctl-auto service. Everything was fine. Today, at home, I was working when suddendly I lost the wireless connection. I rebooted and nothign worked. So I disabled netctl-auto service and everything and tried to manually start it up... Didn't work. But the hotspot from my mobiel phone worked.

So, here's what I'm doing right now:

1. start up my notebook
2. "netctl start alv-w" [note: there's actually a hyphon in the name, tried it without it though]
3. Get the errors:

Nov 01 15:53:29 pdm network[465]: WPA association/authentication failed for interface 'wlp4s0'
Nov 01 15:53:29 pdm network[465]: Failed to bring the network up for profile 'alv-w'

Nov 01 15:53:29 pdm systemd[1]: Failed to start Networking for netctl profile alv-w.

and

   Loaded: loaded (/usr/lib/systemd/system/netctl@.service; static; vendor preset: disabled)
   Active: inactive (dead)

The profile which doesn't work:

Interface=wlp4s0
Connection=wireless
Security=wpa-configsection
IP=dhcp
WPAConfigSection=(
    'ssid="thecorrectssid"'
    'key_mgmt=WPA-EAP'
    'identity="someid"'
    'password="somepw"'
)

The profile which works:

Interface=wlp4s0
Connection=wireless
Security=wpa
ESSID=Honeypot
IP=dhcp
Key=mypw

and I have absolutely no idea what's going on.

That's the same profileas "alv-w". I copied it and just renamed it so it hasn't a hypon in the name. Should I "netctl disable foo" it?

ewaller · 2017-11-01 15:14:36

Yeah, try that. Then see if you can get it to work by hand.

balance · 2017-11-01 15:27:08

Nope, i diabled it, rebooted, checked if its gone (which it is) but I still get the same errors.

cfr · 2017-11-02 03:54:56

But can you connect manually i.e. without netctl?

balance · 2017-11-03 12:10:33

I actually only know netctl, I downloaded a few of the gui applications but I didn't mange to connect. There are all channels used with the same ssid. Also, I booted up win10 and tried it there and it works just fine. All other wifi networks I usually use are just working fine.

IIRC the connection crashed when I tried to mount -cifs a web server. I'm using i3 if that has any relevance. It's probably something stupid/simple.

Search the Wiki on the networking topic and follow the instructions for setting up a network connection manually to see if you can get it connected. After that you can move on to configuring netctl, etc.

I can't establish a manual connection, that's why I tried it with the GUI applications and such.

e.g. I tried it with wpa_supplicant:

my wpa config file is:

network={
	ssid="myssid"
	key_mgmt=WPA-EAP
	identity="myid"
	password="mypw"
}

getting (I termianted it at some point)

Please show what you do from the beginning of the process? Do all the commands prior to use of wpa_supplicant work? You should have got information about the key management etc. as part of the output from those earlier steps. What did that say? That configuration looks incomplete to me, but I'm not sure. See the manual page for examples.

See the manual page for examples.

I looked at examples, so I'm sure my wpa config file is fine.

1. iw dev - ok
2. iw dev wlp4s0 link - no connection
3. ip link set wlp4s0 up - ok
4. iw dev interface scan | grep -i myssid - ok, shows several such networks
5. wpa_supplicant -i wlp4s0 -c wpa.conf (getting the errors above)

I'll recheck my config but the netctl profile is 1000% accurate since it worked and I never touched it and all m yother interface are still working too.

I noticed that if I start up and connect (auto) to my hotspot and then set the interface down (because netctl start myprofile says "interface already up"), I can see the following error in journalctl:

wlp4s0: failed to remove key (1, ff:ff:ff:ff:ff:ff) from hardware (-22)

seth · 2017-11-05 15:40:55

Today, at home, I was working when suddendly I lost the wireless connection.

Sure it's WPA-EAP and not WPA-PSK?

I doubt that's related. We're all getting that. It's a bug, but it just slows down shutdown a little, I think. At any rate, it certainly doesn't stop things working.

Re. config: All the examples I found with WPA-EAP had further configuration details, so if this really is right, then I'd suspect more stuff needs to be in the file. This is not the same as WPA-PSK, as seth points out above.

Hi,

I'm sure because it worked for months with this config. Maybe they changed something but I'm still waiting for an answer and I doubt they would do maintenance in the middle of the day and just dc you.

WHat I did now:

1. tried it with EAP-PSK - didn't work with netctl. When I changed it in the wpa.conf and did wpa_supplicant -B -i wlp4s0 -c wpa.conf it just outputted "Successflly initalized wpa_supplicant but no connection.
2. I downlaoded arch again and put it on a stick, booted it, mounted my linux fielsystem, copied both configs "on to the live system" and tried netctl and wpa_supplicant. same result. (Wanted to isolate the problem from my system configs but I'm not sure if that really did a lot)

I'll for sure redo all the steps and check if I have some errors in my config files etc. When I got the dc I did a mount -t cifs as I said above - if that's somehow relevant.

tried it with EAP-PSK

Errr....???

I thought it was your home network where you couldn't connect. So isn't 'they' you or your house mates/family? If 'they' is your ISP, this sounds like just the kind of thing they do all the time.

It's my "home" network - I live in a house full of students, something like a dorm maybe? So basically you have a ethernet and wlan, ethernet works fine and wlan works fine for everyone else too. There's a guy who manages all the network related stuff. I meant him and his partner with "they".

I'll have a talk with him next time I see him (which is mostly random) and I'll redo everything stated in this thread during the weekend, when I have time. I know that he uses linux too, ubuntu or debian, so I guess he might be able to extract a profile for me. (but maybe he won't, he's usually a bit awkward and not always very supportive )

thanks for the input so far

Ah now I see, must be a typo since I looked at a example which used WPA-PSK. But I'm gonna retry it today evening when I'm at home, maybe I was actually that stupid.

cfr · 2017-11-08 18:23:49

A dorm maybe using WPA-EAP. It would be unusual on a home network for a household, but a dorm or hall of residence is a bit different and may well use enterprise configuration.

balance · 2017-11-09 10:02:05

so I finally rached that guy and they apparently changed the security protocol they r using and somehow didn't properly publish the news... So I have EAP-TTLS/PAP now... Thanks a lot for all the help in here and all the input! They changed it since MSCHAPv2 is unsecure (probably bacuse of that handshake bug in wpa2?) anyway, I bet it should work once I'm back home...
