Hi Alan, That is what I wanted to prove to you... that the Simultaneous Dual-Band WiFi Network knows best... It does not need any inference by users!
Both Daniel and I have mentioned so many time on this mailing list... If Apple systems / devices/ apps etc are setup correctly (the way Apple instructs them to be), they will work as they are designed to do. In other words "If it works as it should... DON'T mess with it"! The old saying "If it ain't broke, don't fix it" Cheers, Ronni Sent from Ronni's iPad4 On 25/05/2013, at 3:11 PM, Alan Smith <[email protected]> wrote: > Hi Ronni > > All went OK.
