Archer C9 v1
when I create the secondary connection - VPN to my office connection speed was down from the 90mbit to 4.5mbit, strange I do all correct, but nothing helped even I reset all settings and update and downgrade firmware, speed is slow by VPN connection, I also test my connection with another device Tp-Link 841HP with this modem everything was ok and connection that I have 90mbit it's same. So what's the problem ?
can you help me to find the solution for this important issue?
thank you !

Good day,
Actually I already switch off:
like QoS or Bandwidth control? Or firewall
but same problem, and I also have a new version of C9 and VR600 but there is no PPTP VPN included inside of system. Why in new version of firmwares doesn’t have any PPTP connection.
Me:
And how I can solve this problem with PPTP VPN connection in C9(v1)?
About my Network I have a LAN(WAN) ISP connection, so that’s it no any devices between that, I have also Tp-Link 841HP there is ok everything is working perfect !
And also, as I know in new model of C9 there is no VPN PPTP connection it's sad
