hi guys
here is the speed graph taken from my 4km link with no nstreme enabled…
not sure why nstreme doesn’t work on my link.
anyhow the speed is going up and down and is not what I’m expecting for -75dbm…

any idea how to fix it will help me alot

Have you tryed to upgrade to 2.9.12?

Regards

3

already tried but it didn’t help any and it was abit slow on my pc (don’t know why)

4

Slow?? :S, try only B or only G… and set basic rates at lowest you can

Regards

5

Do you suggest that lowering basic rates improves constant performance?

6

yes

We are going to have to remove the basic-rate setting as it is making allot of headaches for us and others. The only time you can enable higher basic rates is when you have a perfect connection and it won’t speed things up so much that you can see a difference.
