Ok, here is the thing..

I install Warcraft 3 RoC
I install Warcraft 3 TFT
I download the 56,1 mb patch (War3TFT_124b_English.exe)
I download the Eurobattle net installer

Then...

I install the 56,1 mb patch and then (lastly) i run the installer.

Why, oh why, i get disconnected out of the blue (no waiting time to drop) just when a game starts or randomly (after 5,10 minutes)?

Note that...
a) my net runs smoothly.
b) i am STILL on Battlenet

I uninstalled and re-installed the game more than 10 times. I re-downloaded the installer and the patch, just in case.

Sometimes when i get disconnected i see a message from the host's bot. It says something about Desync and state#1 (me) and state#2 (the rest of the players).

Please, someone with knowledge of this problem that so many people have answer me and provide to me a solution.
