TheGus54,

The update you downloaded is the most current (19.0.1), and should help to resolve the issue. The Broadcom diagnostics is perfectly safe to run, but I don't think the issue is the hardware itself,but lets test it regardless. 

Let me know what you see from the diagnostics, as well as the update. 

Yes the broadcom diagnostics only appears to run a pingtest.

Unfortunately that driver installed qlogic instead of broadcom drivers and rendered all four adaptors unusable.

I am in the process of trying to install version 16.  What I don't understand is why all the tcp/ip settings went back to default.

A simple driver upgrade has turned into a nightmare

Update;

re-ran NIC_DRVR_WIN_R306484 and rebooted, reset static ip and rebooted and it started to work.

The scary bits were:

• the way it hung when clicking 'uninstall' on the adaptors in device manager
• the time taken to reboot

Fortunately the driver has installed ok
