If you were connected before and recently installed a new network adapter driver, rolling back your driver to a previous version might help.
- In the search box on the taskbar, type Device Manager, and then select Device Manager from the list of results.
- In Device Manager, select Network adapters > the network adapter name.
- Press and hold (or right-click) the network adapter, and then select Properties.
- In Properties, select the Driver tab, select Roll Back Driver, then follow the steps. If the button is unavailable, that means there’s no driver to roll back to.
- After rolling back to the previous version of the driver, select the Start button > Power > Restart if you’re asked to restart, and see if that fixes the connection issue.
If Windows can’t find a new driver for your network adapter, visit the PC manufacturer’s website and download the latest network adapter driver from there. If your PC can’t connect to the Internet, you’ll need to download a driver on a different PC and save it to a USB flash drive, so you can manually install the driver on your PC. You’ll need to know the PC manufacturer and model name or number. To learn how to manually install the driver, see the previous section.
