Slow back haul links speed

I have 3xMKRB433 1st starting at my house > 2.repeater > 3.tower.

The links is ± 800m from one another CCQ 100%, I use IP>Routes and has default routes back to my house so I assume it is static routes.

When I copy data from my house to the other end the speed between these MK RB is never greater than 30kb :frowning: ,What can I do to get a better back haul? hoes does the wisp do it for 50 clients?

I’m still a new to this. Can any one please advice me on this.
