I was not able to use WLAN for OVI as it was connecting via o2 active by default.
- I tried deleting the available access points of o2 active from Setting-Connections-Accesspoint.
- The O2 access point were not deleted and moreover now it is showing me as System Error! and not allowing any operation to perform.
I have to take my battery out and replug again.
But if I again try removing the O2 active access point, getting the same E71 error and not allowing to perform any operation.
