Can't find my Network Controller

Hi everyone,

yesterday I installed archlinux on my dell Venue 8 pro, this morning I want to install the wifi driver using ath6kl as recommend in this guide.

The strange thing is lspci -k doesn't find my network controller:

00:00.0 Host bridge: Intel Corporation Atom Processor Z36xxx/Z37xxx Series SoC Transaction Register (rev 0d)
	Subsystem: Dell Atom Processor Z36xxx/Z37xxx Series SoC Transaction Register
	Kernel driver in use: iosf_mbi_pci
00:02.0 VGA compatible controller: Intel Corporation Atom Processor Z36xxx/Z37xxx Series Graphics & Display (rev 0d)
	DeviceName:  Onboard IGD
	Subsystem: Dell Atom Processor Z36xxx/Z37xxx Series Graphics & Display
	Kernel driver in use: i915
	Kernel modules: i915
00:14.0 USB controller: Intel Corporation Atom Processor Z36xxx/Z37xxx, Celeron N2000 Series USB xHCI (rev 0d)
	Subsystem: Dell Atom Processor Z36xxx/Z37xxx, Celeron N2000 Series USB xHCI
	Kernel driver in use: xhci_hcd
	Kernel modules: xhci_pci
00:1a.0 Encryption controller: Intel Corporation Atom Processor Z36xxx/Z37xxx Series Trusted Execution Engine (rev 0d)
	Subsystem: Dell Atom Processor Z36xxx/Z37xxx Series Trusted Execution Engine
	Kernel driver in use: mei_txe
	Kernel modules: mei_txe
00:1f.0 ISA bridge: Intel Corporation Atom Processor Z36xxx/Z37xxx Series Power Control Unit (rev 0d)
	Subsystem: Dell Atom Processor Z36xxx/Z37xxx Series Power Control Unit
	Kernel driver in use: lpc_ich
	Kernel modules: lpc_ich

But ip a find a network interface:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc fq_codel state DOWN group default qlen 1000
    link/ether 88:12:4e:10:08:97 brd ff:ff:ff:ff:ff:ff

If I try to set wlan0 up with

ip link set wlan0 up

returns me a void line without working...

This is my dmesg. Ideas to solve this problem?

Re: Can't find my Network Controller

It is possible that the network adapter is not connected via PCI but e.g. via USB. Check the output of lsusb.
Furthermore, your WIFI adapter is already UP as indicated by ip.

Edit: I just realized that you are following a third party guide. These are not supported here. Use the official Wiki as reference. Otherwise your support requests will most likely be dust-binned by the staff.

Re: Can't find my Network Controller

The lsusb output is received by just keyboard

Re: Can't find my Network Controller

What? I do not understand what you are trying to say. Post the actual output of the command.
Also you don't need this information for your network setup, since the WIFI adapter seems to be working fine. You just need to configure it. Read the official Wiki for instructions on that.

Re: Can't find my Network Controller

Sorry, but I'm not really good in english.

This is the output:

Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 002: ID 0e8f:0040 GreenAsia Inc. USB Keyboard

Re: Can't find my Network Controller

So it's not connected via USB either. Doesn't matter. Just configure your WiFi as you please following the wiki.

Re: Can't find my Network Controller

I followed the guide but it still disconnected.

I tried to use wpa_supplicant configuration but when I've done save_config it returns me FAIL,
if I check with ip a the wlan0 interface remain DOWN, I found on AUR this package but unfortunately it doesn't work

Re: Can't find my Network Controller

Post your actual configuration, the exact commands you enter and the console output.
Also please provide the output of

systemctl --state=active --no-pager

and

ip addr

after the network configuration.

Re: Can't find my Network Controller

The interface is up, the value inside the "< >" matters.
wpa_supplicant and networkmanager are running, do you have a conflict here?

systemctl list-unit-files --state=enabled

If you stop both, can you connect w/ wifi-menu?

Also, what exactly does "I tried to use wpa_supplicant configuration" mean?

Please post your complete system journal…

Re: Can't find my Network Controller

Third party guides are not supported, follow the installation guide: https://wiki.archlinux.org/index.php/Installation_guide

Closing. -- For deletion.

It has been brought to my attention that this seems to be very specific hardware and that the general installation seems to have been done using the installation guide with a few necessary specifics to the HW extracted from the linked guide, I'll reopen this based on that assumption.

Moving to Kernel & Hardware.

Re: Can't find my Network Controller

I'm going to re-open this on request due to the unique nature of OP's hardware.

Re: Can't find my Network Controller

Thanks the reopening,

I've solved the problem to the connection by using nmtui, but my arch continuously doesn't recognize my Network Controller...

Furthermore I've noticed that my wlan0 randomly disconnect.

The interface is up, the value inside the "< >" matters.
wpa_supplicant and networkmanager are running, do you have a conflict here?

systemctl list-unit-files --state=enabled

If you stop both, can you connect w/ wifi-menu?

Also, what exactly does "I tried to use wpa_supplicant configuration" mean?

Please post your complete system journal…

Re: Can't find my Network Controller

If it's completely absent from lspci from time to time then that sounds like an issue with firmware initialization, try to get a UEFI/BIOS update if possible.

Re: Can't find my Network Controller

You have one of those logitech unifying receivers w/ two devices (mouse + keyboard) attached to it, right?
What if you remove that? Does the wifi become more stable?

Re: Can't find my Network Controller

Without keyboard and mouse I can't use the terminal so I must need them.
Anyway, today I used the tablet for 4 hours and my wifi was disconnected just one time.

Re: Can't find my Network Controller

Plug a wired keyboard?

If this is a unifying receiver dongle, it operates on the same frequency band as bluetooth and 2.4GHz wifi, so there's a good chance it causes interference leading to connection drops.
The devices can probably (?) also operate via bluetooth which should™ be less harmfull since the chip can then manage the conflicting radios.

Re: Can't find my Network Controller

Before using a bluetooth keyboard I was using a wired one.

I tried to disable the MAC randomization but it doesn't work

Re: Can't find my Network Controller

And did you have the same issues w/o the logitech unifying receiver?

Re: Can't find my Network Controller

I assume the journal you previously posted is not supposed to cover such random connection loss, is it?
Please post one that does.

Re: Can't find my Network Controller

This error hasn't been appearing since yesterday,
when it happen again, I'll post the journalctl logs.

Re: Can't find my Network Controller

The journal should keep the last couple of boots, is "sudo journalctl -b -1" is from the last boot, "… -b -2" from the second last etcetc.

Re: Can't find my Network Controller

$ journalctl -b -1
Specifying boot ID or boot offset has no effect, no persistent journal was found.

For something strange reason I've missed the /var/log/journal, so I've lost all of my journal logs.
