[Question] my phone lost some wifi password

[crusades]

Hi at all,

I have this problem since many months.... sometime when I register a wifi code to take access into a network, the second time, when I will come back.. and password of wifi is not changed, my innos ask to re-put, as first time...

I haven't understand how it is possible.

Now I am with 3.4 rom, but problem is since have 2.7
