Lenovo laptop, wifi not working but Ethernet is working

[CalvinL]

Hi,

Only recently the wifi on my laptop has stopped working.
Whenever I connect to it, it'll give me the yellow triangle in the bottom right. I've tried multiple solutions, including using cmd prompt and entering different prompts. Thing is, when I plug it in with Ethernet its fine and works as usual. I've tested other computers/devices and connecting to wifi works and they have an Internet connection. I've also checked device manager, uninstalled and reinstalled all under networking and it hasn't resolved it.

Any help appreciated, thanks.

Running Windows 10. Yes, I've tried that and it doesn't solve it.

have you tried using command prompt and typing ipconfig /release then after that finishes ipconfig /renew? Or restarting your router?

Yup, I've tried all basic troubleshooting. Tried a few netsh cmd prompts as well, each to no avail.

Do you have any other computers that connect wifi?
You might need to reset your router.
Did you try to reinstall the wifi drivers?

Yes, I have done. And for IPv6 as well. No change.

is your connection saved to where it automatically connects to the wifi? if it does have you tried deleting the saved connection then reconnecting and entering your key again?

Yep. It does that anyways when i uninstall the wireless adapter.
