Problem with some applications

We have a L2L using 5.4 BH and the RSSI, Jitter, spectrum analyzer are in the good parameters.

In the site B we want to enter to the server that its located in the Site A. However we can use the server and use the applications that it has in 5 or 10 minutes.
We must wait for long time to ingress to the server.
We are losing so much time and we need to improve that connections.
I think that the Canopy has the intelligence to prioritize some applications like this.

Maybe with the Diffserv and the configuration of the codepoints we can improve our connection or maybe with another configuration.

In our test we tried with anothers wireless equipment that are not Motorola and we dont have problems but i wanna use Canopy.

What can u suggest to me…
