Technical: IKEv2 VPN slow on WiFi

[PCGuy7]

Very technical article about how Wifi and Ethernet performance can be drastically different for IKEv2 VPN based on how the network adapter driver handles threads:

http://gary-nebbett.blogspot.com/2021/07/slow-performance-of-ikev2-built-in.html

WiFi Adapter: Intel Wi-Fi 6E AX211 160MHz [driver version 23.40.0.4 and older versions]

Indication of incoming packet method: system worker thread

IKEv2 VPN performance: Very Slow [about 6% of expected speed]

Ethernet Adapter: Intel Ethernet Controller I225-LMvP [driver version 1.1.4.38]

Indication of incoming packet method: DPC

IKEv2 VPN performance: Fast

How do I provide feedback or open a ticket with Intel regarding IKEv2 VPN performance being very slow when used with certain network adapter drivers that are designed differently?

Hello PCGuy7,

Thank you for posting in our communities.


To help me further identify the problem and offer you a solution, kindly provide the following details:

• Does the slow connection only happen when connecting to an IKEv2 VPN? 
• What troubleshooting steps have you already performed? This is to avoid repeating them.
• What is the complete model of your computer? So we can further investigate if this issue might be a known issue with the system.

We look forward to your response! 


Thank you, and have a great day ahead!
