Thank you for your fast reply (and to have understood what I meant).
It seems that Windows can use 2 different networks so it was probably the first thing I had to do (see support,
in french Sorry:

But you say that it's not really the problem...
So I will have to use "
some clever routing" to do this? I have 2 routers for testing this if you can put me on the right way ( ;-) ). I have no knowledge of routing (really nothing) but maybe you could try to give me a boost. Only if you have some time and patience.
First is a WRT350N withh DD-WRT firmware, that I don't use anymore but.... why not for testing something. Other is a WNR3500L v1 with Tomato firmware from Shibby (
http://tomato.groov.pl/).
It seems that this one (I talk about firmware not router) is better that first.
So ?
Otherwise forget it... it's not very important but if you can.... :-)
Anyway thank you for your job.
King regards.
