Known issues

As with every software, this driver pack also has many known issues. There aren’t that many fixes as there are problems with it. The list below only highlights the one we thought would most affect a user:

  • VXLAN switch creation on Windows Server 2019 Hyper V might fail.
  • There might be connectivity issues with certain modules, cables or switches.
  • In order for an Intel Ethernet 800 Series-based adapter to reach its full potential, users must install it in a PCIe Gen4 x16 slot.
  • Flow control settings have no effect on traffic, and counters do not increment with flow control set to TX=ON and Rx=OFF.
  • When a VM is running heavy traffic loads and is attached to a Virtual Switch with either SR-IOV enabled or VMQ offload enabled, repeatedly enabling and disabling the SR-IOV/VMQ setting on the vNIC in the VM may result in a BSOD.
  • Small performance limitations have been seen for some workloads on Windows when stressing both ports of the E810-2CQDA2 adapter.
  • In order to use guest processor numbers greater than 16 inside a VM, you might need to remove the *RssMaxProcNumber (if present) from the guest registry.
  • The Intel® Ethernet Network Adapter E810 might experience an adapter-wide reset on all ports on Windows RDMA driver.

For the complete list of fixes and known issues, read the release notes.


We always suggest that updating to the latest drivers is always better, as it fixes a bunch of issues the users experience each day while improving network security. However, with Intel Ethernet Adapter Driver Pack 26.6, we are not so sure, since it has a bunch of issues that still need to be addressed.


What is Intel Network Connections software?

The Intel Network Connections software is a tool used to manage your network drivers and keep them up to date. It also intimates you when a new version is available.

Do I need Intel Network Connections?

Intel Network Connections is not mandatory for the operating system, However, it does help in keeping the network drivers up to date. If you do not use an ethernet cable very often, you probably do not need to use the Network Connections software.
