WIFI not working -- kernel module problem [Solved]

celacantus · 2017-08-05 21:34:22

Hey guys.

I'm having a difficult time configuring my wireless interface. I think the problem is associated with the kernel modules that are loaded.

rfkill list

gives:

0: ideapad_wlan: Wireless LAN
	Soft blocked: no
	Hard blocked: yes
1: ideapad_bluetooth: Bluetooth
	Soft blocked: yes
	Hard blocked: yes
3: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: no
6: hci0: Bluetooth
	Soft blocked: yes
	Hard blocked: no

and the output of

lspci -k

for the wireless adapter is:

03:00.0 Network controller: Qualcomm Atheros QCA9377 802.11ac Wireless Network Adapter (rev 30)
	Subsystem: Lenovo Device 4035
	Kernel modules: ath10k_pci

I've seen in other Topics people talking about adding to

/etc/modprobe.d/blacklist.conf

a line with

blacklist ath10k_pci

But it excluded the interface that was working from rfkill

0: ideapad_wlan: Wireless LAN
	Soft blocked: no
	Hard blocked: yes
1: ideapad_bluetooth: Bluetooth
	Soft blocked: no
	Hard blocked: yes
2: hci0: Bluetooth
	Soft blocked: no
	Hard blocked: no

Thanks in advance

What does that mean? What have you tried, and what are the specific messages you have received?

rfkill list

gives:

0: ideapad_wlan: Wireless LAN
	Soft blocked: no
	Hard blocked: yes
1: ideapad_bluetooth: Bluetooth
	Soft blocked: yes
	Hard blocked: yes
3: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: no
6: hci0: Bluetooth
	Soft blocked: yes
	Hard blocked: no

That indicates there is a hard block on the interface. It could be due to missing firmware, but it could also be that your machine has a mechanism for disabling wifi -- a switch, a function key combination, etc... Can we assume you have checked this?

Yes, I've checked bios/UEFI and wireless is enabled. An whenever the airplane key on my keyboard is pressed the rfkill output turns into

0: ideapad_wlan: Wireless LAN
	Soft blocked: yes
	Hard blocked: yes
1: ideapad_bluetooth: Bluetooth
	Soft blocked: yes
	Hard blocked: yes
3: phy0: Wireless LAN
	Soft blocked: yes
	Hard blocked: no
6: hci0: Bluetooth
	Soft blocked: yes
	Hard blocked: no

I've been reading on the wiki about wifi and searching for answers on forums but no result yet.

With the ath10k_pci loaded and rfkill showing no softblock or hardblock for phy0 what commands are you running to establish a network connection and what are their outputs?

celacantus · 2017-08-05 22:13:49

I'm tying to use the gnome GUI for NetworkManager. When I turn on the WIFI nothing show up.

seth · 2017-08-05 22:18:02

stop the networkmanager service and follow https://wiki.archlinux.org/index.php/Wi … nual_setup to figure whether there's a problem w/ the device or with networkmanager.
Ensure the device is not blocked in rfkill.

celacantus · 2017-08-05 23:15:23

thanks seth. Just followed the manual setup guide and discover that it might be a driver problem

Successfully initialized wpa_supplicant
nl80211: deinit ifname=wlp3s0 disabled_11b_rates=0
wlp3s0: Failed to initialize driver interface

I'll have a look and try to find something about driver support for Qualcomm Atheros QCA9377.

Post complete logs/output/versions/error messages

seth · 2017-08-06 06:45:24

As well as

systemctl list-units | grep -iE '(net|wicd|dhcp|conn)'

The message usually means either sth. else is still operating the device or it's hard/soft blocked.

celacantus · 2017-08-06 19:05:50

Thanks for the attention Seth. I tried 2 different drivers on the internet but both didn't work.

I found a workaround. Just disbled NetworkManager and started using netctl + wifi-menu to generate the profiles and it's working 100%.

For those who faced the same problem, disable your NetworkManager:

 sudo systemctl disable NetworkManager.service

And have a look on netctl:

Please remember to mark your thread as [Solved] by editing your first post and prepending it to the title.

Did you understand that the cause is often that you're running several network managing services at the same time? (eg. networkmanager and dhcpcd or so)
netctl might turn out being a bit more robust, but if the above is the case, you'll at some point face problems again.

celacantus · 2017-08-06 19:43:40

Well the thing was that I wasn't running them at the same time. I had NetworkManager first of all and then I disabled it and downloaded netctl to see if it would work. After all, it worked.
