Some Windows users in Europe have reported that Windows 10 update 1607 caused difficulty in connecting to the Internet. The cure is to restart the computer (not shutdown). If that does not work, use ipconfig in the command line to release and renew your IP address to the router. In some cases, flushdns is helpful.
Microsoft has acknowledged the issue and released KB3206632 overnight that apparently has fixed the issue. On checking today both the writer's WIndows 10 devices had both updates installed and no Internet connectivity issues.
The exact cause of the issue is unknown, but basically, some Windows devices cannot get a new IP address from their Wi-Fi router. It is not known if this is a design fault of the brand of a specific network chip in the computer or the router.
