Creators Update Problem

[rccatnap]

I was invited by Microsoft to install the Creators Update this August, which indicated they were satisfied my computer was 'up to it'.
Update went okay, but now my computer does not see any wireless networks.
The wireless adapter is present in my Device Manager (it says 'working properly') and the drivers are up to date. I've checked with Intel using their own diagnostic tool, plus with Toshiba.
The computer is a three year old Toshiba Qosmio X70-A with Windows 10 64 bit (upgraded on-line from Windows 8.1).
There is a Windows 7 computer on the same network operating fine and the router has been rebooted and is working well. I can get on line using an Ethernet cable, but obviously cannot operate the printer wirelessly in another room.
I've flushed the DNS and run sfc /scannow. No indications of any problems.
I have asked also on the Microsoft Windows 10 forum and found that I'd already carried out the 'fixes' suggested. No further response from them.
The latest security update was KB4034674.
Any suggestions other than reinstalling Windows would be gratefully received.

Forgot to mention, I can now also use my printer again wirelessly.

Thanks for the feedback. I'm pleased that you've (more or less) got the problem sorted.

To Buenchico & Togo; after the last big Windows update, I hesitantly removed the USB wireless dongle and tried using the internal one again. Lo and behold, it worked...... and still does. It seems that the problem has been addressed, by either Toshiba or Microsoft, but I suspect the latter. I've got my USB 3 port back at last.
