Microsoft recently released KB3201845 build 1393.479 to users. But now some users reporting ‘No Internet Connection’ issue after installing update KB3201845. The issue is caused by a problem with DHCP (Dynamic Host Configuration Protocol) on Windows. Microsoft also acknowledges the issue and suggested a fix for this problem.
Users need to run following commands in the Command Prompt(CMD). In the search box on the taskbar, type Command prompt, press and hold (or right-click) Command prompt, and then select Run as administrator > Yes. Once CMD is opened, enter the following commands one after another:
netsh winsock reset catalog
netsh int ipv4 reset reset.log
If you are still facing ‘No Internet Connection’ issue, you need to renew your PC’s IP address. To do so, open up CMD (Win +R, type in “cmd.exe” and hit enter) and type the following command in:
ipconfig /renew
