I was running Windows 8 on a Lenovo G780. After updating to Windows 8.1, WiFi does not work anymore - I always receive a "DNS server not responding" error. I have tried using public DNS servers from Google, and also restarting my router, but with no results. All other devices on my network are having no trouble at all.
I've tried updating the wireless driver, but the manufacturer's website claims that the Windows 8.1 driver should be updated with the update from Windows. So I can't find a wireless driver.
Anyone else having this error and does anyone have any ideas on how to fix it?
Here are the driver details:
Broadcom 802.11n Network Adapter
- Provider: Microsoft
- Driver Date: 2013-05-31
- Driver Version: 188.8.131.52
- Digital Signer: Microsoft Windows
