[Lenovo Y480] Wi-Fi no longer working, out of ideas on how to proceed

2016-08-24, 0:01 AM

Lenovo Y480 Ideapad (late 2012), Windows 10


Issue: Attempting to connect to Wi-Fi, status is "No Internet, secured"


Wi-Fi works fine for iPhone and MacBook


Device Manager-->USB-IF xHCI USB Host Controller (Intel WiUSB) "This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)"


The driver was from 2012 and according to Windows there were no updates. Intel Driver Update did not bring up an update either. I removed it completely with the intention of attempting to reinstall it but there does not appear to be any way of doing that. 


The following drivers did not work (after restarting):

Intel PROSet/Wireless Software and Drivers for Windows 10

Intel WiMax Driver for Windows 8.1(32-bit, 64-bit) - IdeaPad Y480,Y580


Where do I proceed from here?


EDIT: MTB file with detailed network info can be found [here](http://www.tenforums.com/network-sharing/61280-wi-fi-no-longer-working-out-ideas-how-proceed.html#post786918)


RESOLUTION: The issue has been resolved thanks to a user on another forum. I had to install this driver, restart, and then I was able to connect to WiFi again. My internet still wasn't working ("dns_probe_finished_bad_config" error message on every website) but was able to get that resolved quickly with this.

Fix Wi-Fi connection problems


Try rebooting the network. Unplug the modem and router, wait a minute, plug them back in, wait two minutes, and try again. If that doesn't help, try connecting the laptop to the router via an Ethernet cable. If still getting the same problem then follow the below given steps:


Step 1: Check settings & restart. Make sure Wi-Fi is on. Then turn it off and on again to reconnect.


Step 2: Find the problem type. Device. Try connecting to the Wi-Fi network with another device, like a laptop computer or friend's phone.


Step 3: Troubleshoot by problem type. Check network password.

Try uninstalling the drivers and reinstall the latest ones.
