Intel(R) Dual Band Wireless-AC 7260 cannot scan/find any network

Jump to solution

Hello everyone,

I have a NUC (Intel NUC D54250WYK - I5-4250U Intel HD5000) with Windows 8.1 and Intel Dual Band Wireless AC 7260. My problem is that it does not scan/find any networks, neither the 2.4/5 from my router nor my mobil phone hotspot/any of the neighbours. My personal networks works perfectly with any laptop.

Haven't managed to find any threads for this specific issue, most of the ones regarding AC 7260 are about temporary dropout/disconnects.

I have installed the latest drivers, tried uninstalling, disabling/enabling and updated windows with the latest updates aswell. When running the manual diagnostics test, provided by the PROSet Tools, it passes the radio test (with radio on) but fails on the scanning test stating that there are no networks available for connection.

Any thuoghts? I don't have any idea on how to troubleshoot any further.

Below is an outprint from netsh regarding the drivers.

Best regards, Johan

jlinaker, the results from the netsh command are just fine.

I assume that for some reason the antenna cables are disconnected, so I would check on that first.

You may also try repairing the TCP/IP stack.

Is this always or only after resuming from hibernate? I have a separate thread I opened yesterday about the wireless card being shut down by Windows after resuming from hibernate here:

You are correct Joe, had forgotten to attach the antenna cables (Doh!). Thanks for the correction
