vpn speed

Hi, ASUS RT-AC86U WRT-Merlin 384.7_2 Diversion, Skynet, OpenVPN Server, OpenVPN Client (paid service) I'm using ExpressVPN in one of the 5 OpenVPN Clients. And lately I've noticed that the VPN connections slows right down. The solution I've been using is to restart the client and that fixes it...
