Upgraded my Asus notebook with 8260 WiFi card to v20 driver from Intel (Asus has still not released) on Win 10 (Windows update updates to v19) to deal with KRACK vulnerability. It all seems to work (back online, everything running) but now the network icon in the system tray shows a red asterisk, no connection, and the tooltip says "Not Connected - No Connections Are Available". It's lying to me, I'm connected over WiFi, just the icon that seems to indicate otherwise.
We understand that your network icon in the system shows a red asterisk after upgrading to latest Intel(R) PROSet/Wireless software.
We would like to let you know that this is expected after updating the driver. Could you please confirm if the same situation happens after restarting the system?
We look forward to hearing back from you.
