Windows 10: Suddenly unable to enable wifi

Recently, there was a moment where I was connected to a Wi-Fi network and suddenly lost my connection. When trying to get to the Wi-Fi menu, the option had disappeared, and I no longer have the option to enable Wi-Fi.I've tried a number of suggestions, including performing a network reset. I've even downloaded a wlan driver from Lenovo on another computer, moving it to mine, and running the installer, but the driver still doesn't show up in device manager. I'm unsure what to do next. This is occurring on a Lenovo Ideapad Flex 5 14ALC05

Win10 computer suddenly unable to access printer on home wifi

For some reason, the printer lasted less than 24 hours printing correctly, and now I again can't fix it, even by doing what "worked" before (Comment #6 upthread).

Regarding the static IP suggestion:

1. The printer is connected via USB to a Windows 7 computer on the home network. It's not on the network by IP address. Here is a screenshot of the printer port properties.
   
   
2. Although there ARE "headaches" as is said above, the vast majority of the other computers on the home wifi network, NEVER have had a problem printing to it. And this applies to computers that have run XP, Win7, Win10, and MacOS. For the most part until now, it's included the particular Win10 computer in question.
3. If I still might be able to give it a static IP address, will this affect the other computers that have been able to print to it fine using printer name?

 

Wifi suddenly turns off then back on but unable to reconnect again

Hi Julian,

One of the usual reasons why a specific device suddenly unable to connect to a network is due to outdated/incompatible drivers. We would like to know if you've performed any changes before you encounter the issue.

As an initial troubleshooting, we suggest using the Network troubleshooter as it can identify and provide fixes for it. Kindly follow the steps below:

• Open Settings.
• Choose Network & Internet.
• Click Status, then look for the Network troubleshooter and
  click it.
• Wait for the process to finish and check if the issue still persist.

Furthermore, if the issue still persists, we suggest that you roll back to an older version of your driver as the cause may be due to compatibility issue. Kindly follow the steps below:

• Open Cortana and type in Device Manager.
• Choose Network Adapters, locate and right-click the driver for you Wi-Fi, then select
  Properties.
• Select the Driver tab, and then select Roll Back Driver.

Update us with the outcome so we can provide further assistance.
