Hello, I have a customer PC which behaves in such an incomprehensible way I had to post it here.
Here's the facts: it's a desktop with Windows 10 and a PCI wifi card.
Wifi used to work, now it suddenly has stopped. It will connect and receive ip and dns through dhcp, but won't even ping the router.
And here, the strange stuff begins: I tried in my office and it worked. Cleaned it up, reset winsock and tcpip, brought it back. Doesn't work.
So I tried with a usb wifi adapter. Same behaviour.
I decided to format and reinstall Windows 10. And here's what totally blew my mind. Now it has the same behaviour in my office too, with the usb wifi adapter (still haven't tried with the pci card). It's a frakking fresh install for criminy's sake!
I honestly don't know what to think.
