Laptop can see but not connect to wifi [including hotpot]
I have a Lenovo Legion laptop running Windows 11 that yesterday inexplicably stopped connecting to wifi.
It can SEE all the wifi networks, available, but when you try to connect, it simply says it can't connect to the network. When attempting to connect to networks it's been on before, it asks for passwords, even though there have been no network changes. Then it fails to connect, even with correct passwords.
I tried using my phone (iPhone 17, up-to-date, have used as hotspot dozens of times before with no issues) as a hotspot, and when enabled the laptop sees the hotspot pop up, but when it tries to connect, it causes my phone to restart. This has never happened before, and now ONLY happens when my laptop now is trying to connect. It can hotspot another laptop in the home perfectly fine right now, I checked.
I have tested the wifi with other devices, including another laptop. They are all fine; the problem is definitely with this laptop. It worked one day, I put it to sleep overnight, and the next it did this. No changes, no damage.
Connecting to my router with an ethernet cable DOES work for now.
What I have tried
- Restarting
- Shutting down and waiting hours before starting
- Resetting network settings
- Running Windows network and internet troubleshooter; restarting the wifi network adapter (from Windows network troubleshooter); resetting the wifi network adapter; restarting computer after each of the previous
- Turning off and on wifi
- Making sure Windows Update is up-to-date
- Checking if there was a recent Windows update (not in the 18 hours between "wifi works" and "wifi doesn't")
- Running Lenovo Vantage scan of components
- Disabling wifi adapter/card in Device Manager then shutting down and restarting
- Uninstalling wifi adapter/card in Device Manager and restarting
- Installing drivers from Lenovo (link)
