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: 6.30.223.102
- Digital Signer: Microsoft Windows
2Which driver do you have installed? The manufacturer driver or the Windows Update driver? Have you tried removing your driver and installing the one from Windows Update? – Josh – 2013-10-25T18:10:26.597
@Josh R I've reinstalled it using this method, still not working! I've edited my post with driver details – char1es – 2013-10-25T20:21:25.130
1Here: Same Notebook, same Windows Version and same driver version. But .. not the same problem ;) WiFi-Networking sometimes (!) doesn't work, though connected to Router. Helps to disconnect and reconnect. The "only" other problem: Signal strength seems to be a bit lower than before (with 8.0) – igrimpe – 2013-10-28T16:14:49.493
Lenovo P400 here, and I have the same problem. I went directly to Intel's site to update the wireless drivers as Lenovo did not have current drivers for 8.1 for this model. I have installed the Intel drivers and rebooted yet the problem persists with the Wi-Fi connection going "stale" after a while. – jonsca – 2013-10-31T09:26:22.427
