[Solved]Can't find/connect to network with wifi-menu or another method

Lotoras · 2016-02-11 12:15:12

Hello everyone,

I've searched a couple of other forum entries regarding my issue, but no one else seems to have exactly the same problem as I do.

The problem is that I cannot connect to the Internet with my freshly installed Arch Linux using wifi-menu (I installed dialog), but any other method doesn't work either.
The weird thing is that I have another OS installed (Win 8.1) on the same computer and there's no such issue. I don't have the problem with a Live USB (Kali Linux) either - it finds the network and can connect to it. Additionally it worked with Arch Linux before I reinstalled it.
Further more there wasn't any problem connecting to the Internet in the "base install" of Arch. Only the real OS doesn't get it.
But the actual thing is that wifi-menu doesn't find my network. It can find any other network - from neighbours, networks in my surroudning. Everything except mine.
My networks name is "FRITZ!Box Fon WLAN 7270" but wifi-menu can find networks with a similar name.
So I don't think this is a hardware problem or that my network can not be found at all.
I would really appreciate your help.

For one, it does not appear that you actually started wpa_supplicant. I could be wrong. How do you start it? by hand? As a service? Using NetworkManager, netctl or wicd?

Also, the network shows as down. As a sanity check, let's try a site survey to see if the radio works.

Look at the output of sudo iw wlp0s10f1u2 scan
It should be rather verbose, Check to see if the access point you are trying to attach and all of its attributes are found in the output.

Oh I forgot to mention those 2 things.

I started wpa_supplicant with the command

wpa_supplicant -B -i wlp0s10f1u2 -c /etc/wpa_supplicant/wpa_supplicant.conf

And I already scanned my system with the command you proposed and that's the problem. It doesn't find my network either (but it finds other networks).

ewaller · 2016-02-12 15:28:06

I missed that point. I'm not sure how I missed that point, you were quite clear

Two things to check. First, is the AP to which you want to connect on the same band as the ones you can detect? (2.5 GHz vs 5.0GHz)
Is your regulatory domain set correctly? If not, your computer may not be searching all of the channels available in your area. The router may be on a channel you cannot see if they are set for different countries.

Lotoras · 2016-02-14 18:07:14

Oh I think that's the issue.

I checked the regulatory domain

sudo iw reg get
global
country 00: DFS-UNSET
...

But it should be "DE"
Unfortunately I can't change that. I used the command

sudo iw reg set DE

But it doesn't change anything. But I don't know why.

But I'm pretty sure that you're right because I checked the frequencies with

sudo iw list

and the frequencies 2472 Mhz (Channel 13) - this is the one my network works on - and another one are disabled.

I'll update if I figured out how to change that and when I'm sure that this was the problem.
Thanks a lot for your help

I'm not sure why that command did not seem to work. What happens is you edit /etc/conf.d/wireless-regdom and uncomment the the line for Germany, then reboot?

When you say it did not work, did you try to read it back after setting it?

Lotoras · 2016-02-15 07:05:57

I don't even have a "conf.d" folder in "/etc"??

But if it helps, I have a file called "ieee80211_regdom"

cat /sys/module/cfg80211/parameters/ieee80211_regdom
00

But I can't change that file, even as sudo?

What do you mean by reading back? I tried to set it and then I checked with the "get" command and it's the same as before.

I solved this little issue
I just forgot to install the crda package, my bad.
It's working now.

Thanks for your help
