NetworkManager do not work with iwlwifi / Intel Wireless 8265 / 8275

English Network/Internet
1

Hello,

I cannot use wifi on my Lenovo Miix 720 Laptop. After boot wifi is disabled and if I enable wifi it scan inside yast but not in NetworkManager-Applet. Outside of yast I can not use wifi. I have the suspicion that it is maybe a root/user-problem (permission). But /usr/sbin/iwlist scan works great without root-access.

Here any terminal stuff:

For a better handle on this report back with the output of the following…

nmcli d

nmcli g

nmcli dev wifi list

Check that the wpa_suuplicant service is active (no errors?)

systemctl status wpa_supplicant

Here ths outputs:

Do you have a button to enable Wlan?

7

On the keyboard, I have a Airplane button.

I push the button and after that:


➜  ~ sudo rfkill list all
0: ideapad_wlan: Wireless LAN
    Soft blocked: yes
    Hard blocked: yes
1: ideapad_bluetooth: Bluetooth
    Soft blocked: yes

2: phy0: Wireless LAN

    Hard blocked: no
6: hci0: Bluetooth

    Hard blocked: no

I push the button again:


➜  ~ sudo rfkill list all
0: ideapad_wlan: Wireless LAN
    Soft blocked: no
    Hard blocked: yes
1: ideapad_bluetooth: Bluetooth
    Soft blocked: no
    Hard blocked: yes
2: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no
6: hci0: Bluetooth
    Soft blocked: no
    Hard blocked: no

Another hardware button is not available.

Reboot, goto Bios, reset the Bios to default, save and exit.

9

Not successful. Same output from rfkill.

Look in /etc/modprobe.d/

I assume this is using the iwlwifi module. If not, modify as needed.

There should be a file ending in iwlwifi.conf. Please post that.

Also, try pressing the airplane button as the laptop boots, but before opensuse starts to load. May have to try the reboot twice if the first press turns wireless off.

You can also try:


sudo rmmod -f iwlwifi
sudo rfkill unblock all
sudo modprobe iwlwifi

If none of that works post:


modinfo iwlwifi

I have blacklisted the module ideapad_laptop. Now wifi and bluetooth works. I don’t know for what is the usage for this module. In the description contains this: IdeaPad ACPI Extras

echo "blacklist ideapad-laptop" | sudo tee /etc/modprobe.d/ideapad-laptop.conf

Thanks at all

No, this module will be loaded at boot regardless of whether such a file exists. Configurations files in the /etc/modprobe.d/ directory are used to pass module particular module options when necessary to udev, (which uses modprobe to manage the loading of the modules at boot).

BTW, the rfkill utility can only control soft-blocking not hard-blocking. The latter implies that the hardware has been switched off or disabled a a system level (eg via a hardware switch or BIOS).

Good find. That module is to handle hotkeys for some Lenovo Ideapad laptops…

Thanks. Hotkeys works fine without this module, too.
