Thanks a lot ballscrewbob, I´m happy hearing that you comment.
First of my wifi is 2.4 GhZ and the second one is 5 GhZ, so the first should be detected and I don´t know why then.
Any idea? - very debilited wifi signals of my neighbours (e.g. 27% power) are detected wihtout problem.
Checking the properties of my 2.4 GhZ signal it is "WPA2-Personal" - I thougth it was "WPA2-PSK", should it be admitted too?
Thanks again !
