I've had this phone for 6 months now and struggling to fathom out how to fix the problem on wifi. I can go online and emails are being received. However, I have to turn wifi off and use packet data to send emails. This phone's mac address has been added onto our router, I think the IP address, etc mirrors that of our router. I'm on Orange. I've tried keying a code into the number pad as a test and its not fixed the problem. Can anyone help?
