Or, even better in my opinion, go to Settings, General, Reset and reset the Network. I do this every so often to get rid of the multitude of connections.

Yes, but they are generally very easy to remake and flushing the connection repairs them. I have done this to improve performance on my iPhone.

Is there a reason you need to flush DNS?  Not using a connection may work, but that is not my experience.  What problem do you have?

The other thing you can try is: Connect, and then forget the connection. Remake just that one.

I have seen the Airplane Mode suggestion before, tried it, and it failed. The only way I have been able to reset a connection is to forget it and remake it.

My iPhone has been half way around the world.

it was exchange active synch was move to another exchange server , but the calendar entire did not work so it was moved back to the original server , so I was thinking some DNS issue

Or I was trying to make sure it was not a resolving the wrong Ip to a server name

we are just going to go with resetting up the profile , not to big of a deal


I appreicate the help

If the need is just a DNS flush, Airplane Mode is the best solution and it works just fine

If the troubleshooting requires more than a DNS flush, like reset IP settings or general connection issues then you are correct, a RESET is the perfect solution
