Users of Windows 10 are experiencing a recurrence of WiFi problems, with connections dropping - problems that reports indicate pre-date the recent release of an update (1607) to Microsoft's latest client operating system.
Windows 10 was plagued with such problems at the time of release, but subsequent updates had resolved the connection bugs.
KB3201845 was released on 9 December, but the problems started on 7 December and appear to be affecting some Windows 7 and 8.1 machines as well. There's no pattern in terms of ISPs, routers, and WiFi cards - at the moment, at least, it appears to be random.
The really weird bit is that not only can it not be 1607, but it can't be any patch as none were issued in the days leading up to the outbreak. The Anniversary Update has had its share of problems, but this isn't one of them.
Running the troubleshooter is sod all use as it tells you that "WiFi doesn't have a valid IP configuration", which is a problem, not a solution. But then that's Windows Troubleshooter all over.
Microsoft has had a chequered history with WiFi in Windows 10 and has already put the buffers on its WiFi Sense service which shared passwords with trusted contacts because everyone turned it off anyway.
We've had this exact problem of signal drop in the office and it is an absolute pig to fix.
According to Infoworld, some experts have speculated that the issue is caused by a fast boot which sets the machine to an IP address of 169.x.x.x, but that's not definite.
In a post by Lonnie_L from Microsoft, the company advises: "We are looking into reports that some customers are experiencing difficulty connecting to the Internet.
"We recommend customers restart their PCs, and if needed, visit https://support.microsoft.com/help/10741/windows-10-fix-network-connection-issues. To restart, select the Start button from the taskbar, click the Power button and choose Restart (not Shut down)."
Problem be, the source of the problem is still unknown will continue plaguing users until a patch is released.
