We are having issues with an X1 Carbon USB to Ethernet Adapter.
We have logged multiple support calls with Lenovo, and all they do is send out new adapters. I now have 3 adapters..!!
The issue are having is that we connect the USB to ethernet adapter to the machine, and everythings works smoothly for 3-5 minutes. It then drops the network connection and stops working.
We have updated to the latest drivers for Windows 8, changed power management settings, tested on a Windows 7 Machine, tested on 2 different networks, and different cables and we all get the same issues.
Lenovo is hopeless in supporting this, so i am looking for other ideas from the community no how we could fix this. We have another called logged, but guess what, they are sending me another adapter.. Ill have enough spare parts for life at this rate.
Any thing you guys suggest that we can try, or is anyone else expericencing the same issue?
If their is any Lenovo Representitives on here, i would love a call from you to help us out. We are a large business with over 150 laptops from lenovo, and right now, im ready to stop buying lenovo aftert all the issues we have with support on this case.

Hi, try disabling all USB ports power saver (4 of them) in device manager.

I've not heard of this issue, and I searched our Tier2/3 defect tracking system and can't find any reports of this problem there either. What exactly happens after "drops the network connection and stops working"?
- does the adapter still have IP address?
- does "ipconfig /release" and "ipconfig /renew" help?
- does Device Manager show any issue?
- is there any error in Event Viewer?

We have had many problems trying to get this to work:
in relation to your questions:
- does the adapter still have IP address? - yes it does
- does "ipconfig /release" and "ipconfig /renew" help? No, it released and renews, but we still cannot communicate
- does Device Manager show any issue? - Device shows as working ok.
- is there any error in Event Viewer? - No errors
What we have found is that we must set the port on our switch (Brocade FX1600) to 1000mb, and the adapter then works but is stuck at only 100mb.
We have now bought a $20 adapter and it runs perfectly at 1gb..
i have 5 lenovo adapters if any one wants one!!

I am having the same problem.
Spent many hours on first X1 Carbon and was eventually sent a second. Just open it - updated it and it lost ethernet connection in about 5 to 10 minutes.
What was the adaptor you purchased which worked for you? Thank you
