Slow WIFI speed GL-MT300N-V2

Hi had anyone experienced slow speed when turning into a repeater and dropped further with VPN on?

My mango dropped 50% speed when I setup as a repeater, and another 50% dropped with enabling VPN that is 25% of the original WIFI speed of my router…anyone got an idea how to tackle the slow speed prob?

Wireless speed in repeater mode will be halved (half the time receiving, half the time transmitting). VPN, particularly OpenVPN will tax the processor and cut the speed further. Try Wireguard if you can.
