Win11 - DNS lookup is slow when connected to AWS VPN
I need to connect to works VPN using AWS VPN Client v3.5.0, but when I do this I get severe lag on DNS lookups for public domains
This does not happen when the VPN is disconnected and it is not an issue for any other team members, however as far as I know they are not on Win11.
I have:
- Checked that there is no other VPN client installed
- Disabled IPV6 on both my wi-fi connection and the vpn connection
- Installed and ran wireshark which apparently fixed a similar issue with win10 for some people
- Ran
Set-NetIPInterface -InterfaceAlias Wi-Fi -InterfaceMetric 4advised by someone with a similar issue - Reinstalled the VPN client
- Updated windows to latest
Windows details:

Version 22H2

I found the following article.
After installing the preview release KB5025305 or later updates for Windows 11 22H2, the communication speed when connecting to a VPN may become abnormally slow in some environments.

This seems consistent with your version.

The article states that uninstalling the update will solve the problem.
So it may be a good idea to uninstall it temporarily.

this may work but my windows install was on 17th may and the update was on the 9th - it looks like it was installed as part of windows and it's not in my list of windows updates to remove it.
Also, my connection speeds are actually unaffected. Speedtest.net reports the same download and upload whether I am connected or not - it's specifically DNS.
