Hello, I am running ubuntu 18.04, kernel 5.4.0-42-generic. Last week, the internet randomly stopped working. Turns out the network manager somehow disappeared, so I downloaded the debians on another computer, transferred via USB, and then installed. Now my ethernet works, but my wifi is still not working. When I go to settings and click on wifi, it lists "no wifi adapter found". I figure this must be a software issue, because the wifi was working two weeks ago. I have tried updating the computer, both from command line and software center, but this has not solved the problem.
Code:
sudo lshw -C network
produces:

Based on that output, I found this driver here:
https://linux-hardware.org/index.php...24fd-8086-9010 that I think is the right one for my wifi adapter. Unfortunately, I'm not sure how to install it. I downloaded the file, and went into software and updates-->additional drivers. Here, I can see listed:
Code:
Intel Corporation: Wireless 8265/8275
This device is not working.
(option 1) Using iwlwifi driver backport in DKMS format from backport-iwlwifi-dkms (open source)
(option 2) Continue using a manually installed driver
(option 3) Do not use the device
Option 3 is selected, and the other two are greyed out. The "revert" and "apply changes" buttons at the bottom are also greyed out.
Code:
sudo modprobe iwlwifi
produces:
Code:
modprobe: ERROR: could not insert 'iwlwifi': Operation not permitted
I tried running in su prompt as well, with the same result.
produces:
Code:
modinfo iwlwifi | grep filename
produces:
Code:
filename: /lib/modules/5.4.0-42-generic/updates/drivers/net/wireless/intel/iwlwifi/iwlwifi.ko
Finally, I tried booting from the previous kernel, but encountered the same problem there as well--"no wifi adapter found".dr
Any suggestions? Help would be greatly appreciated!
