I have a Lenovo Thinkpad X240 that I've used for years, but after doing a factory reset to prepare it for sale, I've realized that the WiFi capability has disappeared. Now, the only internet connectivity options available are Ethernet or mobile data. I've tried several troubleshooting steps:
- Checked both Lenovo's and Intel's websites to see if I could find a missing driver, but installing what I could find didn't help.
- Made sure Airplane mode isn't enabled.
- Did a network reset through the settings and rebooted the laptop.
- Updated Windows.
I'm starting to wonder if this device ever had WiFi capability or if I'm just overthinking the need for a driver. I don't recall ever having to use dongles for this thing, except for my wireless mouse.

First, check your Device Manager for any driver issues. It’s a good idea to look for any devices with warning signs next to them. If you find any, right-click them, go to properties, and then check the details tab. You'll want to copy the hardware IDs and Google them to find the right WiFi driver.
If that doesn't work, it might mean your WiFi board is faulty or possibly even missing from the laptop entirely.
If all else fails, you could always get a USB WiFi adapter. They’re pretty cheap—around $13—so that's an easy fix if you're not able to get the internal WiFi working.
