LAN connection not working after Windows 10 upgrade

vbrecken · 10-06-2015, 07:33 PM

I have a Toshiba Satellite P50t-B running with Intel i5-4200H CPU. It is connected to a Toshiba Dynadock u3.0 docking station PA3927U-1PRP. I purchased the laptop and the docking station in January of this year and it was running Windows 8.1. At that time everything was working fine. I upgraded to Windows 10 in Aug and now the LAN connection is not working. I have a flashing amber light and a solid green light on the back of the dock but the laptop indicates no network connection.

I have deinstalled the all the drivers, rebooted, and reinstall the 7.9M2 drivers with no success.

Please see the attached log files

I did run the process. I received the following messages...
"The best driver software for your device is already installed"
"Windows has determined the driver software for your device is up to date"
"DisplayLink Network Adapter NCM"

Can you take a look at the attached log file to see what the problem is?

Hello,

There are some incoherence reported, and it makes it more complex to understand.
Your Device Manager view reports that there is a DisplayLink Network Adapter NCM with proper drivers.
However, when you look at all the network cards present with an ipconfig/all, the DisplayLink one is absent and all cards are disconnected.
The reason for that would be if your DL card was deactivated in your Device Manager, but I can see this is not the case.

I can see some issues on your USB communication during the enumeration of the network card. (that's the part where everyone introduces themselves on the USB: "Hello, I'm DL Ethernet and you can fetch my drivers as VID_17E9&PID_4305".

To put aside any installation corruption, I would like you to use our installation cleaner. This will make sure nothing is left behind and you can do a clean reinstall using 7.9M3.
Once you have done this, I would need a new log files to see if there are any more complaints in them.

KB724494 - Cannot upgrade or uninstall DisplayLink software

Would that be possible?

Yes.

I performed the following actions...
1. Ran the EndUserCleaner 7.9.723
2. Rebooted
3. Downloaded DisplayLink7.9M3
4. Disconnected all devices from the Dynadock
5. Disconnected the Dynadock from the USB 3.0 port
6. Ran the DisplayLink7.9M3
7. Connected the Dynadock when requested
8. Rebooted
9. Connected the monitor, USB keyboard, speakers, and ethernet cable to the Dynadock. All work except the ethernet connection.

Rand the DisplayLink Support Tool 1.0.0.25. The files are attached.

After the latest code upgrade provided by Microsoft, this issue is now resolved. Windows 10 issue.
