On a brand new D54250WYK with Windows 7, 32 bits, I installed all drivers from the recent bundle (30 June), then updated the BIOS. Everything works fine.
Then I inserted the 7260HMWBNWB card. When Windows started, it automatically downloaded some drivers, but the top one (network adapter) failed, while the others succeeded (bluetooth, etc.)
I then installed the Intel PROSet/Wireless Bluetooth Software.
The Intel Drivers Update Utility shows that the Wireless Networking Device is unknown or not supported - screenshot below
I then manually downloaded the driver for the 7260, installed, rebooted, but it did not improve the situation.
I then opened the NUC, took the 7260 card out and plugged it back in again.
7260 BEFORE MOUNTING:
7260 MOUNTED:
7260 MOUNTED UNDER THE mSATA:
Anyway, to no avail, the card remains unknown or not supported.
Likewise, nothing shows under Windows adapter settings - screenshot below.
In device manager, there is an exclamation mark next to Network controller with an error "The drivers for this device are not installed." Update driver automatically won't work.
What further troubleshooting steps can I do?
Is this model supported on the D54250WYK: Intel 7260HMWBNWB ??? - I thought so as per my research before purchasing this model.
Is this a hardware failure? Of the 7260 card? Of the NUC?
I have a few days left to return the wireless card or the NUC without penalty, so swift support is appreciated.
