I have bsnl's wifi broadband at home, to which I am able to connect our 3 laptops easily. I am able to connect out Lumia 510 phone too, without any difficulty. But I am not able to connect thru my e5. The network authentication I have set is 'mixed wpa2-wpa-psk' and WPA encryption is AES. My e5 phone shows that the wlan is available, but when I try to connect after giving the psk, it gives a message "Wlan not found". It is very frustrating! When I try thru Nokia Asha 305, the system rejects saying: "invalid key", though I enter the correct key. Finally, only Lumia 510 works - not e5, not asha 311! Please help!
