We have a similar problem in our organization as some have written here before.
Unfortunately there is still no solution.
During a VPN connection, the bandwidth when working in a WIFI connection is very low.

Wired file copies are in the 10 MB/s range.
Wireless file copies are in the 1 MB/s range.

This applies to all home users.
This is not an individual situation.
Has anyone already encountered this and perhaps found a solution?

    What will be the difference if you measure your wifi against wired without VPN connection? Any difference do if you use 2,4GHz vs. 5GHz? 5GHz might have some compatible issues with older WLAN adapters.

    By AoVPN, I'm referring to the IKEv2 and certificate auth based always on VPN whose setup is described here https://www.youtube.com/watch?v=aZ-thDAfuBM, referenced here https://learn.microsoft.com/en-us/windows-server/remote/remote-access/vpn/always-on-vpn/deploy/always-on-vpn-deploy, without DirectAccess.

    By "MSVPN" I'm referring to the "on demand" PPTP VPN services from Microsoft, generally available since around 2000. https://en.wikipedia.org/wiki/Point-to-Point_Tunneling_Protocol

    @Thomas Gusset @Gary Nebbett SSTP works. No notable networking issues. I did have to disable revocation check on the client as we are self signed here.
    I'll look into what it takes to have a "Revocation Service".
