Gigabit CT Desktop Adapter loses connection to local network on daily basis

[KVieb]

We are using an Intel(R) Gigabit CT Desktop Adapter (device id 0x10d3) to connection to our local network on a Windows 10 PC (DELL optiplex 9020), driver version 12.12.50.6, driver date 20/03/2015. 'Update Driver' (online) yields 'The best driver software for your device is already installed'.

This network adapter looses the connection to our local network on a daily basis (sometimes less than once per day, sometimes several times a day).

On some occasions, after the crash we can't even find an event on the Event Viewer. On other occasions we get this event at the time of the crash:

Miniport Intel(R) Gigabit Adapter, {...long string...}, had event Fatal error: The IM miniport has failed to initialize.

On the Device manager, there is a yellow ! next to the device, saying that windows found a problem (code 43).

After restarting the PC, everything works fine every time.

One more peculiarity: after the crash, the 'Power management' tab on the device manager for this device disappears.

We've disabled 'Allow the computer to turn off this device to save power' (while this was possible). Also, we've disable all power saving options on Windows 10 and on the BIOS.

It is crucial for our application that our PC never looses its network connection so this issue is very frustrating.

Many thanks

Hi KV291,

Thank you for posting at Wired Communities. Just to double check if you have tried the following:1) Change the cable to test2) Un-install and re-install the driver3) Install the network adapter in other system to test if will encounter the same issue4) Have you also check with Dell support if CT desktop adapter is a validated network adapter on their system to check for compatibility.Thanks,wb

Dear Sharon and wb,

Thanks for your input.

1) Checked different cable, still keeps happening.

3) We are using another network adapter of the same kind (on a different PC, connected to the same local network) and it has been working for a year without problems. I think this also answers 4)

Regarding 2), un-installing the driver: We have managed to 'Uninstall device' from the device manager but without any effect. However, we suspect that this 'Uninstall device' does not actually remove the driver software: As soon as we select 'Rescan for hardware changes' the network adapter appears instantly with the same driver installed. We spent a couple of hours on google on how to remove drivers but found no easy way of doing so. What would you suggest?

Also, we've purchased another identical network adapter and the problem persists.

Thanks,

Konrad

Hi KV291,

Thank you for the reply. Code 43 error usually can be fixed by un-installing then re-installing the driver. The CT desktop adapter does not have Intel driver in Windows 10, it used the built-in driver from Microsoft*, please refer to this website for reference, the table list CT desktop adapter support inbox driver only which means it used driver from Microsoft. You may check with Microsoft for the driver. http://www.intel.com/support/network/sb/cs-035770.htmAs you mentioned the other CT desktop adapter works well on different PC, can you check with Dell support if there is compatibility issue? Thanks,sharon
