[AC Question]

Hello.
I have bought in november 2016 in Cambodia a Icall P9 phone. Back in Portugal working very well. I did make a factory reset and than appeared what I have written. The phone is working with everything, but not possible to connect on wifi also not Google etc etc. Another phone is still working on the same router, also my pc. There is nothing changed on the router. Also in the IcallI is nothing changed. Is there somebody who can help me??? I am not a professional, so please keep it easy if you can help me. Thanks very much. Fred.
