I am posting a follow up question to the below linked question:

Lenovo 18.04 No Wi-Fi Adapter Found

After reading the comments it seems that the advice works...for someone who has a wifi connection, which I cannot establish. So I was wondering if I could perhaps get chili555 or a similarly kind and knowledgeable soul to continue writing the advice for how to get the missing files when no wifi or hard wired connection can be established?

For reference, I'm running a fresh Ubuntu 18.04 LTS on a brand new Lenovo Yoga C930, dual booted system. I ran

lspci -nnk | grep 0280 -A3

And received the output

6b:00.0 Network controller [0280]: Intel Corporation Wireless-AC 9260 [8086:2526] (rev 29)
Subsystem: Intel Corporation Device [8086:0014]
Kernel driver in use: iwlwifi
Kernel modules: iwlwifi

Some of the tools that I have access to: I have access to a separate machine with interwebs and I can transfer files via usb. I also have access to the internet via Windows 10, and I have heard that Ubuntu can read data files on an NTFS partition on Windows 10, but I have not been successful at figuring how to set this up or verify it.

I'm a similar level ubuntu practitioner to the question I am referencing, so please be gentle with me (and feel free to direct me to resources that can improve my literacy!)

Thank you all so much for your help!

    You should check results for rfkill list and see if anything is blocked – Jeremy31 Aug 23 '19 at 21:27
  • There are no missing files that need to be downloaded. You already have a driver, namely iwlwifi and if it is not working as expected, it is almost certainly, as @Jeremy31 says, due to rfkill; that is, the wireless switch or key combination is set to disable (kill) the wireless radio. – chili555 Aug 23 '19 at 23:50
  • Results for rfkill list:

  • so, after the comments above, I did some searching for Wireless Hard Blocked on Lenovo machines... entered BIOS through windows and the wireless is enabled there...still searching for solutions. – Pinkie B Aug 24 '19 at 01:47
  • does echo "blacklist ideapad-laptop" | sudo tee /etc/modprobe.d/ideapad-laptop.conf make any change after a reboot – Jeremy31 Aug 24 '19 at 09:51
  • well, now my results for rfkill list are 0: phy0: Wireless LAN Soft blocked: no Hard blocked: no – Pinkie B Aug 26 '19 at 14:47
  • also: yes, it works! Thanks! – Pinkie B Aug 26 '19 at 14:54

Solution: 

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

and then reboot.

Results:

rfkill list

0: phy0: Wireless LAN
      Soft blocked: no
      Hard blocked: no
1: hci0: Bluetooth
      Soft blocked: no
      Hard blocked: no

Also, wireless now works. Very simple solution not requiring web access. Yay.
