I have a software application that runs on a laptop running Windows 7 SP1 which receives data at around 100Mbps via a UDP stream over a 1GbE connection. I've run the software on multiple laptops successfully in the past (older network adapters - e.g. 82577LM) . Recently I installed the software on a newer model laptop which has a 82579LM network adapter. When running the software on the laptop with the 82579LM adapter. With the 82579LM adapter I'm seeing approximately one lost packet every 25K-60K packets.
1. I'm running the version 16.7 (latest) of the Intel Network Drivers
2. Windows 7 - SP1 + latest updates
3. I've observed the same behavior on multiple laptop models by different vendors which contain the 82579LM adapter.
Searching the Internet I've seen some postings of issues under Linux complaining about similar 82579LM adapter issues:

And some more here:

Since this is running under Windows 7 SP1 we obviously have different drivers but I'm wondering if the issue is related. Any ideas for things I could try to fix the issue?
Thanks,
Ryan
