After Annivesery update all LAN-connections lost

Greetings.
Updated 2 PC's. After update they can't find anything on LAN except the printer.
My LAN is 2 PC's a WD Live TV -box (linux) and a network-printer.

Before the upgrate it worked fine.

Is there a setting, that I need to change to get LAN working again? The fault is on both PC's, so I guess it is some setting that has changed, but I can't find it.
"Network sharing center" settings is the same as before the update on both PC's.

I'm confused why they at least can't find themself, as they has allways showed up in "Network" in Explorer.

First try to uninstall the network adapters in Device manager. Then scan for new hardware. If this does not work go to the manufacturer of your network adapters and download drivers. If manufacturer does not have drivers, also try the PC manufacturer. I hope this helps.

Reinstalled Intel Chipset driver V10.1.1.7_whql. Rebooted, and problem solved.

I still don't get it. I could access Internet, Network-printer and my router, but nothing on LAN. But the driver reinstall helped.
Now everything works fine.
