Hi guys! Just like the topic says, my internet wifi doesn't work in my laptop other than ethernet but it works fine in my phone and other devices. Please help me.
By Operating System I meant which version of Windows.
---Windows XP, 7, 8, 8.1, 10 or whatever.
It is good to know the brand of laptop too. (Which you posted already.)
I have Windows 8.1 Pro which has a Troubleshooter in Control Panel which can be used to check out various problems.
With Windows/10, WiFi issues have typically been found in the chip driver.
Don't rely upon Win Update, you'll end up where you already are; a bad driver.
Find the Make/Model of your WiFi chip in the Device Mgr and then go to the site for that Make, look for the Support/Download/Firmware page and select the driver for Win/10 {32 vs 64}bit. Download and install
