Hello everyone. I'm new here on this sub and am desperately in need of help on my laptop. Three days ago after disconnecting to my campus wifi, my laptop suddenly cannot detect any wifi signal. I have a Lenovo Ideapad 300 which I got last year, so I thought it was weird to encounter this problem I've never had before. All my other devices (other laptop, iPhones) can connect and detect without any problem.

I have disabled/updated/enabled/restarted my driver, tried everything on the Lenovo website and it still won't work. I have also reset my operating system but still it won't detect nor connect. Tried resetting my IP but commandprompt says my wireless/bluetooth/ethernet stuff are not connected and not operational. Please help?

UPDATE: This morning while sitting through my Biology class, my laptop suddenly detected faint signal of the campus wifi, even though all my other devices are receiving strong signals. Also tried connecting my laptop via ethernet cable, but still won't connect to the internet.
 
Solution
Try removing battery, and holding power button for 30 seconds and then replace battery and power on and test.

Or other scenario is checking in device manager if windows has power management control over it, disable, reboot and test.

Okay I've unchecked the power management control over it and it still doesn't work. I'll try to remove the battery this afternoon.

My daughter had the same problem. I tried all those suggested remedies posted on google, Microsoft and Asus. NO LUCK. Then I think and focus on the operating system that is Windows 10 and I found out that after the latest update she looses the WiFi. So I looking for the latest update on her computer (On your screen bottom left hand corner next to window symbol - Type here to search- Type there Windows update - select Windows update settings - select Update History - select the latest update then select UNINSTALL.{for my case Security update for Microsoft Windows(KB4074588)}. After you select UNINSTALL the screen will pose for 8 to 10 minutes as nothing happen. Be patience. Then uninstalling screen (small rectangular screen) will appear and gathering information to uninstall the latest update. It will take 45 minutes to an hour. you have to sit beside your computer and do other things while keep an eye on it if it is going to sleep mode just drag the cursor etc. After uninstall the latest update you have to restart your computer. It will take another 25 minutes because it has to rearrange all the software things. Once you log on Type WiFi at Type here to search window at the bottom left corner screen and select Change WiFi settings and you can see your WiFi there type your WiFi password and you are connected. You can't stop updating Windows 10. The uninstall update will automatically update again but this time we hope both the update and WiFi will work without any flaw. Thanks. T. Jeyaseelan.
