I'm new to ubuntu. I'm running 18.04.3 from a USB drive on a Lenovo 130S-11GM laptop. It finds the bluetooth adapter ok, but it can't find the wifi adapter.

The adapter is an Intel Dual Band AC3165.

I ran the sudo rfkill list command and it showed the following:

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

BTW, the bluetooth works just fine.

I ran the sudo rfkill unblock all command, but nothing changed.

I ran the command: cat /etc/modprobe.d/blacklist-ideapad.conf And the result was the following: cat: /etc/modprobe.d/blacklist-ideapad.conf: No such file or directory.

I ran the command "uname -r" which returned the result "5.0.0-23-generic".

I ran the command "dmesg | grep iwl" which returned the following:

  [   31.755409] iwlwifi 0000:03:00.0: loaded firmware version 29.1044073957.0 op_mode iwlmvm
  [   31.887621] iwlwifi 0000:03:00.0: Detected Intel® Dual Band Wireless AC 3165, REV=0x210
  [   31.915790] iwlwifi 0000:03:00.0: base HW address: a0:51:0b:11:d7:fd

  [   33.576920] iwlwifi 0000:03:00.0 wlp3s0: renamed from wlan0

Thanks.

**NOTE******* Whereas I never could get it to work with Ubuntu 18.04, it works fine with Ubuntu 19.10 "right out of the box".

  • When I click on the little triangle in the top right corner, the drop-down windows shows "Wi-Fi-Hardware Disabled". Then I click on that and then select Wi-Fi Settings, the resulting window displays a big question mark with the message "No Wi-Fi Adapter Found", "Make sure you have a Wi-Fi adapter plugged and turned on". When I boot to the installed Windows 10, the adapter is "found" and works fine.

  • My apologies for the unformatted edit. I can't seem to figure out why it eliminates all my formatting (indents, spaces, etc).

  • "Hard Blocked" means a hardware switch, and cannot be controlled in software. Look for a keyboard toggle, usually one of the Fn-keys. Good reference: askubuntu.com/a/98719/19626

  • Please check whether the wifi driver is enabled in Software and Updates, under the Additional Drivers tab. That should fix the problem if it falls under that category...

  • I did that. It says "No additional drivers available" in the middle of the window and "No proprietary drivers are in use" on the bottom left. I'm sure I need to install one, but without connectivity I can't figure out how.

Reset to default

Run in a terminal

sudo tee /etc/modprobe.d/blacklist-ideapad.conf <<< "blacklist ideapad_laptop"

and reboot.

That should fix the hard block.

  • @karel It can be marked as a dupe of one of my ansers where I explained that in details, but I can't find it.

Download the driver for your Adapter.

Unzip the files and copy 2 files with .ucode extension to /lib/firmware.

  • There is no "driver" there. The driver and fimware are loaded already.

  • OK, remember, there's no connectivity on this machine. So I downloaded it using another machine onto a separate USB drive. Can't figure out how to install it. Also booted Ubuntu up on my mac (from a USB drive) and downloaded it there. Still can't figure out how to install it.
