Laptop not connecting to home wifi/network disappearing.

Question

Heyo, I've been having issues lately with my lenovo laptop (Windows 10) no longer connecting to my home wifi network.

Whenever I try to sign in to my network it will tell me that I cannot connect to the network, and afterwards the network itself disappears from my list of available networks (This is attempting to connect with both automatic connection and manual connection, neither work).

I have tried multiple online sources and followed many different types of troubleshooting guides, I've tried resetting my modem and multiple restarts of network and device settings and yet all options which are supposed to help resolve the problem are not working. I have gone in device management and gone through all the advice I've found online but nothing has helped solve this.

The driver is up to date and there are no other options I have found to fix this.

It is a slightly older laptop now (approx 2017) so I wouldn't be surprised if it's just on the verge of dying but any information on how to potentially fix this would be appreciated.

Hi there,

Is the Wifi working fine with other devices?

First, try running the troubleshooter

Select the Start button, then type settings. Select Settings > System > Troubleshoot > Other troubleshooters.

Under Other, select Network Adapter > Run.

Try running these network commands to manually reset the TCP/IP stack, release and renew the IP address, and flush and reset the DNS client resolver cache:

Select Search on the taskbar, type Command prompt. The Command Prompt button will appear. To the right of it, select Run as administrator > Yes.

At the command prompt, run the following commands in the listed order, and then check to see if that fixes your connection problem:

Type netsh winsock reset and select Enter.

Type netsh int ip reset and select Enter.

Type ipconfig /release and select Enter.

Type ipconfig /renew and select Enter.

Type ipconfig /flushdns and select Enter.

Restart the PC after this and see if it is helpful, if not try the repair update.

Hi Nott,
Can the laptop connect to other Wi-Fi networks? For example, can it connect to your smartphone's hotspot?
Try these options:
Option 1: Try uninstalling / reinstalling the wi-fi adapter driver by following this procedure:
https://www.drivereasy.com/knowledge/how-to-reinstall-wi-fi-driver-on-windows-10-easily/
NOTE:This is a non Microsoft website. The page appears to provide accurate and secure information. Beware of ads on the site that may advertise products often classified as PUPs (potentially unwanted products).

Option 2: Try to change the driver manually:

1. Go to Device Manager> Network Adapters, right click on your network adapter> Update Driver.
2. Select "Search my computer for drivers"
3. Select "Choose from a list of drivers available on your computer"
4. Windows will propose 2 or more compatible drivers for the network adapter in use, select a driver other than the one currently in use> Next. The driver will be installed automatically. Reboot the pc.
   Otherwise, if it's a laptop, download and reinstall the latest available version of the Wi-Fi driver from the pc manufacturer's website.
