Like the title says, I'm experiencing very slow speeds when using my VPN router with ExpressVPN's own firmware even when using an ethernet cable, the speed I get when I connect to the secondary router and disable the VPN is around 250Mbps but as soon as I enable the VPN that drops to around 25-30Mbps, I have tried all the different protocols and I've talked with their support for hours and nothing helps. The router I'm using is the Asus RT-AC56U. Any help is greatly appreciated. Thank you.
