Yes, okay, I really like to try MinimServer.
How should I try it, can I also use the standard ASUS firmware ?
What is important and what functionality must an alternative firmware have for MinimServer ?

Following the instructions in the Minim link:
As far as I have understood MinimServer is written in Java and therefore an embedded Java installation is needed. ok, following the ORACLE link there are eleven diffferent embedded Java downloads for v7 an v8.
Which one is the correct one for ASUS RT-N65U, is this important ?

Since my ASUS router is not having a ARMv6 or ARMv7 CPU
(I think so, guessing RALINK is not an ARM CPU, right ?)

I am already confused with the first step installing JAVA on my router

Sorry if my questions are too simple or for you... I am not a JAVA or Linux expert at all
