If your Windows 10 PC or laptop has suddenly started losing WiFi connection, you are not alone. Last week Microsoft rolled out out a new update KB 3201845 for Windows 10 Version 1607 designed to fix minor bugs and glitches.
Among the fixes were improvements to ongoing battery drain and some minor compatibility issues with Internet Explorer Following the update, users reported that they started losing connection to Wi-Fi, with others saying they had began receiving a “No Internet Connection” error message.
The issue was first believed to have only affected users in the UK but now appears to be more widespread, according to a report in The Register. Microsoft later confirmed the issue on its official support forum.
Luckily there seems to be a couple of fixes. Option 1: Microsoft says the problem could be fixed by simply performing a clean restart. You can do this by holding down the Shift key then clicking on Start > power icon > shut down. Make sure you don’t let go of the Shift key until your PC has completely shut down.
Option 2: Is to perform a roll back to the previous version of Windows 10. You can do this by clicking on Start > Settings > Update & security > Recovery > Get Started > Go back to an earlier build. This will uninstall your current version of Windows 10 and go back to the build you were previously using.
Option 3: As reported in The Register, is maybe a little more complicated, but is likely to fix the problem without having to roll back to an older build of Windows 10. In the Task Bar type “Command prompt” and enter the following commands in the order below:
netsh winsock reset catalog
netsh int ipv4 reset reset.log
If this fix doesn’t work then Microsoft also has an official help guide which offers a range of solutions to standard connection issues. Option 4: Microsoft has said it is aware of the problem and is working on a fix so you could just wait until that is available. Source: Thaivisa
