54Mb connection(tested at 27Mb) Is there a way to go faster?

I need 45Mb(real speed)
We are using two rb433ah, each with a single anttenna. Without changing hardware is there a way to go faster?
Nstream?
Turbo?
I searched the forum and heard a lot about 60Mb and 70 Mb. How?

It is possible to reach 45Mbps in turbo (40Mhz channel), but you need good SNR, good ccq (>80%), no interference… I recomend using XR5 or UB5

5Ghz turbo testing at 41.2-44.5Mb. Thank you

Anything else?

(perfect line-of-sight, very little interference)

CCQ 100% ,disable CSMA, enable nstreme, fix rate at 54mbps in turbo…this settings gave me 75mbps TCP traffic

Use three cards and ospf (or maybe this new meshing I am hearing about) , skip the turbo. You should get 20m on each card and be less prone to outages/ interference.
