    Default Latitude e5570 with Intel 8260 - No WiFi

    Hi, all -
    I've been playing around with this all day, and I've had no luck getting the wifi on my laptop to work. It's a brand new install of Leap 15.2 on a Dell Latitude e5570 with an Intel 8260 WiFi adapter.
    I'm using Network Manager, not wicked. Wired internet works just fine, but I can't even enable wireless. Whenever I open the Network Manager applet and click the checkbox for wifi, nothing happens.
    Any suggestions would be much appreciated.
    I've put the outputs of a few commands that other forums addressing similar issues ask for, hope that helps. Let me know if any more info is needed!
    Thanks a million for your help!

    Here's a few more. After running nmcli g the first time, I saw that it was telling me that WiFi was disabled... I haven't yet figured out how to enable it. I did change the STARTMODE in /etc/sysconfig/network/ifcfg-wlan1 to auto after that, and rebooted, but that didn't fix it. And as shown below, nmcli g still shows WiFi disabled after that.

    Check rfkill status
    Code:
    rfkill list
    If 'soft-blocked' you can unblock wifi with
    Code:
    sudo rfkill unblock wifi
    Then try to connect via NetworkManager.

    More info

    man rfkill

    Thanks, Deano_ferrari!

    I ran rfkill list, and this is what I got:

    Code:
    0: dell-wifi: Wireless LAN
            Soft blocked: no
            Hard blocked: yes
    1: dell-bluetooth: Bluetooth
            Soft blocked: no
            Hard blocked: yes
    2: phy0: Wireless LAN
            Soft blocked: no
            Hard blocked: no
    So both wlan and bt are hard blocked...

    Ok...

    Embarrassing, but true.

    New laptop, I didn't see the WiFi enable button on the keyboard. It was as simple as that. I suppose that's what "hard block" means...
    Classic case of "check the easy fixes first..."

    Sorry it was something that stupid!
    Thanks for the help!

    Yes, that is exactly what it means - hardware disabled.

    All good. It's all part of the learning, and this thread might be useful to others who come searching.
