Has anyone successfully used the latest Windows btest software?

Running the PC version - to radio, over ethernet only, I get a max of 20kbps

Running the PC version, to another PC with the same btest s/w on it, gives me 1200bps.

same here...

You have to type in a speed, and it will try to get to that speed.
(You can't leave it at 0)

eg. 1M 10M 100M

AFAIK that's needed when using UDP.
Using TCP it should try for maximum.

EDIT: I stand corrected. Even for TCP you need set the limits.
Odd because it's not like that when using Tools/Bandwidth Test directly from Mikrotik device
