I have BSNL wi fi BB connection with Dlink ADSL 2730 U wi fi modem with WPA2 Encryption.MY lenovo andriod mobile connects to it with the encryption password. But my cousin's LUmia Windows mobile didnt connect to the Wi fi router despite entering the correct password.It goes upto "authenticating" and stops.a message is displayed " no response from wi fi" !Is the password just not enough to connect to a "secured" wi fi router? in another "case" my lenovo mobile couldnt connect to the BSNL wi fi modem at my relative's house in Chennai!there also it had WPA2 encryption! If anyone on this forum had a similar experience please clarify on this! Thanks in advance.
