Hi
How to connect two computers for tranfer files togther with wireless connection .

Better to use the KISS method.
Grab yourself a flash drive and transfer them that way.
Flash drives are extremely inexpensive and simple to use.

Thanks for answer .
I use this way when transfer small data

But now I want tranfering 15 g.b

Simple enough as Flash drives currently run up to 256 Gb although those cost a bomb.

Well. I'm not going to do all the work for you (since it's pretty easy to find this info on the web... google is your friend), but I will point you in the right direction. What you're trying to do is called Ad-Hoc wireless networking, and it's not too complicated if you don't mind changing network settings. Give it a search, and you should find some decent instructions there.

Thank for all
