Thanks Aaron for your quick reply.
According to what is listed on newbielink:http://www.linux-wlan.org [nonactive]
some USB Wifi dongles are known to be supported in linux while also other ones may be OK but yet to verify, so if you didn't take anything out from Debian distro I expect that some of them may work also for me.
I agree with you that streaming video on a wifi connection may result in poor performances.
The point is that I don't have network plug over the house, and the phone plug (where DSL service is available) is not located in a good position to fit all needs.
Placing new cables inside the wall is not an option (I'm living in a rented apartment, when I'll move to my new house everything will be possible), neither fixing cables on the wall across doors and rooms (my small kids would LOVE to rip everything out ... :roll: ).
So my idea is to find (with some advice and some trial and error ...) a reasonable compromise in order to have everything connected and decently working.
At the moment I have 2 option:
keep a dedicated core close to phone/DSL plug and put a wireless MD close to tv/stereo set
locate an hybrid close to tv set with a wireless connection to DSL router
Either way I have to deal with wifi devices under Debian, and I would prefer USB dongles as they are easily movable to other boxes.
As soon I get all the needed hardware I will try some configuration and will let you know.
Thanks again and regards
