UPDATE since my kernel and firmware updates weren't saving on reboot I moved the question to here: (Terminal commands not saving on reboot. Lenovo X1 Carbon Gen 7, Ubuntu 18.04)
I am having the same issue as this post (No WiFi Adaptor found in Lenovo X1 Carbon Generation 7), however nothing suggested in the post has worked so far. It looks like the solution is to upgrade my firmware from -43 to -46 but I have no idea how to do that. See the output I have posted below.
I originally installed 18.04 LTS on my brand new Lenovo x1 Carbon Gen 7. My WiFi card is Intel(R) Wireless AC 9650 160MHz. Currently I am not able to connect to WiFi, and my WiFi Panel says "No WiFi Adaptor Found". These are the things I have done so far:
- Disabled Secure Boot
- Followed the instructions in this video (https://www.youtube.com/watch?v=dokG4bCF4GQ)
- Followed the instructions in the top comment of this post (No WiFi Adaptor found in Lenovo X1 Carbon Generation 7)
- Upgraded to Ubuntu 19.10 as the OP did in this post (No WiFi Adaptor found in Lenovo X1 Carbon Generation 7)
- Reinstalled Ubuntu 18.04 (my current version)
- Tried installing the driver for my wifi card in /lib/firmware (https://www.intel.com/content/www/us/en/support/articles/000005511/network-and-i-o/wireless-networking.html)
Please let me know what I can do to fix this. I have spent the last 3 days trying to troubleshoot this issue and nothing seems to work, I am pretty frustrated.

EDIT: to those of you who are suggesting this post (No WiFi Adaptor found in Lenovo X1 Carbon Generation 7), none of the solutions work there. I have tried them all. The problem right now seems to be that nothing in terminal is saving on reboot.
