Your images do not show what is under "Other Devices" in device manager, so I can only presume that the missing devices are listed there, but here are some steps I would recommend.
I would start by Installing and running Lenovo Vantage and then from under Health and Support, run a a Hardware Scan.
If the Hardware Scan completes with error(s), please view the log and post the results.
If the Hardware scan reports no problems, next run Windows' Check Disk utility to scan and fix filesystem errors
If the Check Disk scan finds no errors, then open Lenovo Vantage again and run System Update to check for and install the latest drivers.
If that complete nomrally, open Lenovo Vantage again, and run System Update to check for updated device drivers for your system.

I have this same issue - it is intermittent and only began to happen within the last few weeks.. The Yoga 900 turns on without a wifi adapter. I cannot find anyway to activate the adapter. I have to shutdown the computer and power it back on to get the wifi adapter to show up.
I am worried that eventually the wifi adapter will never show up.
What can I do to ensure that the wifi adpter always shows up?

Hi Paultherrien! Welcome to our forums community. Try updating the wireless driver from our website: https://pcsupport.lenovo.com/gr/nl/products/laptops-and-netbooks/yoga-series/yoga-3-pro-1370-laptop-.... It is under Networking: Wireless LAN.

Ok, Installed the new driver.
I was required to remove "INTEL PROSet/Wireless Software" in order to install the new version "INTEL PROSet/Wireless Software
We'll see how this goes.
Thanks very much

Hi paultherrien! In device manager, click View> Show hidden devices. You should see the driver grayed out. That means that the wifi card is not functioning. This is a hardware issue and repair is needed. Please contact your local Lenovo support for service repair.
Please use this Global Contact List to get the contact number: https://pcsupport.lenovo.com/us/en/supportphonelist?CID=ww:lenovosocial:20x9m6

Thanks for the information.
I ended up rebooting my laptop on battery only and now the wireless connection is up.
I don't suppose it has anything to do with my power source at my office? I am plugging into an extension cord that is plugged into a powerstrip. Honestly, the only time I seem to have this issue with the wireless adapter not being available is when I am at the office and plugged into this extension cord.
But when the issue occurs again I will take your advice and try to look at hidden devices to see if the adapter is there or not.

I'm having what would appear the very same issue on a new Lenovo Yoga 310-11IAP. I only got the machine out of the box yesterday and upgraded it from the completely crippled Windows 10 S to Windows 10 Pro.
At some stage post upgrade I noticed that the wireless connection had gone, not only that the complete adapter had disapperaed from Device Manager. So upgraded the BIOS to the latest version and also all the device drivers to run under Windows 10 Pro. Still no wireless adapter!
This morning I switched on he machine from cold and plugged it into a wired ethernet network and ran some Windows updates. Lo and behold the wireless adapter suddenly appears at some point. I join my local WiFi network and run some tests using the Lenovo diagnsotics tool. All seems good.
Then poof 15 minutes later its disappeared again - nothing on the system - like it never existed.
Have I got a duff laptop here or is this some weird power management or driver issue?

I don't have an answer to your issue. Just want to acknowedge your frustration.. Since my post back in December my system has not had any issue with the wireless adapter...and I am not certain what 'fixed' the issue.
