Hi,
Right now I'm running a AC-RT86U. Enabling VPN Client significantly reduces the speed. Is there (meanwhile) a more powerful Asus Router for VPN?

The ac86, ax88, and ax86 are all close in openvpn performance. They all should be able to achieve around 200 Mbps. If you are way below this with your ac86, it could be that your vpn provider doesn’t have very fast servers or possibly you are using a server very far away, degrading performance.

Try switching server locations to see if that makes any changes.

200 Mbps is the usual speed I can achieve with running the VPN client on my PC (AMD Ryzen 9 3900X). Enabling it on router for the same server it's dropping to 30-60 MBbps.

What settings are you enabling on the router VPN past defaults?

What are your ISP speeds up/down? How consistent are they (Fibre, DSL, cable, satellite, etc.)?

Have you tried using the second or third, or fourth/fifth VPN slot to test with?

1- Nothing I guess, just the settings I got from my VPN Provider
2- 400/400 Mbts, very stable, Fibre
3- Yes, I did. No change.

1- ???

What other changes past defaults have you made on your router? What options/features or scripts are you using?

What firmware are you using? When was that firmware last set to full factory defaults?

If using scripts, was the USB drive inserted 'used', or was it formatted on a PC in NTFS format first before cleanly installing the scripts you use again?

sorry, misunderstood that. As I had to do a factory reset today (384.18) I will check the performance again. No USB Stick.

The RMerlin 386.1_0 release final firmware is suggested (highly). No sense fixing this on such an old firmware today.

Flash to the 386.1 codebase and reset your network and router as suggested in the link below.

I'll do. Upgrade from 384.18 to 386.1 worked this time. I guess I'll do a hard reset again to make sure everything is fine.

Is the VPN client on your PC using openvpn or wireguard?

Which provider do you use?

What are their crypto settings, specifically tls control channel and auth digest. I’m wondering if your provider is using an extra strong encryption which is slowing the router down?
