Re: iOS loses WiFi when sleeping Just out of curiosity how do you know it's dropping Wi-Fi? Is it not updating? What are the symptoms? Does it show a cellular data connection every time you wake it? Are you not seeing it in iTunes?

It doesn't appear in iTunes (iTunes only recognizes iDevices in WiFi).
When you touch the device to wake it, it shows 3G. Only when you slide the bar and start to unlock it will it toggle to WiFi.
It shows 3G >90% of the time on wake up...maybe more. |

I don't agree, it shouldn't drop as iCloud automatic backup requires the phone to be plugged in and connected to WiFi to do it's thing. In addition, iTunes WiFi automatic sync requires the phone to be on WiFi. If I'm not mistaken, it slept in WiFi before upgrading. How are you determining that an iCloud backup needs to happen and is not? If an iCloud backup is not needed, why would wifi have to be on/active when the iDevice is otherwise idle?

I have a couple of things that tell me if something is actively connected via WiFi. One is the phone itself will show 4G instead of Wi-Fi momentarily after being woken up. It does not do this when actually plugged in to the mains. When waking up when it's plugged in the Wi-Fi icon is displayed already. Network Magic from Cisco also shows me what is connected on my network and if it's Wi-Fi, wired or inactive. My router also has a DHCP client status page that does the same thing. This is how I can tell what the phone is doing. In my case it's nothing do with iCloud etc as I do not back up to iCloud.
iOS was changed sometime back I believe to make Wi-Fi stay on if plugged in/charging as there is no concern about battery usage. If unplugged then yes, it will drop Wi-Fi until woken up.
It sounds like there are now some Wi-Fi problems/inconsistencies in iOS6x and some hardware.
As for iTunes, my installation can drop the device from the list even when the device is active on Wi-Fi. I do not find the iTunes thing a reliable indicator of whether a device is on Wi-Fi or not.

It shows 3G >90% of the time on wake up...maybe more. Ok I'm sure you know what I'm going to suggest ... but before we go down that road though let's try deleting your Wi-fi account from your iPhone, then reboot both your phone, and your Airport extreme. Re-astablish your Wi-Fi account on your iPhone, again reboot both the phone & the router.
Now once both have finished rebooting open up iTunes plug in your iPhone, make sure the box" sync this iPhone over wi-fi" is checked, and preform a manual sync, when the sync finishes do not eject the iPhone from iTunes just simply unplug it.
If this has not resolved your problem ... Restore As New!

Then they are not functioning as they should. The point being made is the phone should stay connected to Wi-Fi all the time, even when the screen is not on when it is plugged in to the mains. This is by design. My iPhones have done this as long as I can remember. I understand the point. I'm just saying that none of mine, my girlfriends, or several of my friends iPhones stay on WiFi while sleeping. Seems like intended behavior... The intended behavior is to keep connected if it's on AC - otherwise drop.

Both iDevices woke up in wifi this morning!
Of course, the process was not without a few hitches, including losing Internet after rebooting Aorport Extreme router (I made the wife call Comcast so it was pain free to me)...yes, I tried a power cycle.
In addition, for some reason iTunes cable sync failed. I googled it and found I needed to delete (preferences/devices) the backup.
But other than those minor glitches, it worked.
FWIW, on iPhone, I followed your instructions. However, on iPad, all I did was forget the network, reboot iPad and cable sync to iTunes. I didn't want to have router issues again and I assumed that since I already rebooted the router once, what ever magic this step performed was already done.
In any event, thanks for your help! |

up until today when i woke my IP4 (now running 6.0.1) it would show 3g for a second or two and then go go to WI-FI (i thought it was normal). As of this morning it now just stays on WIFI and wakes that way. I did nothing this fixed itself. i woke it about 10 to 12 times and it wakes in WIFI each time. |

Nothing too technical about all the rebooting. All we were doing was deleting the old connection, and letting all of the devices get a fresh new handshake with each other. Glad to hear your iWorld is back in order.

@comcast.net | What you're describing is normal behavior for the device. It's always done this, even under iOS 4 and 5. You might just not have noticed it. Also, keep in mind that if you connect to a new WIFI (or in this case, delete the home WIFI and reconnect it), it'll remain attached to that WIFI for as long as you don't move away from it. Once you get out of reach from it and it no longer becomes the last attached and last connected WIFI hotspot, the device will default back to turning off WIFI when sleeping.
It's a pattern I noticed a long time and and it hasn't changed its behavior in quite a few iOS versions. Also, you don't have to unlock it to bump it back into WIFI mode when it's sleeping. Just wake it... it just takes a few seconds to connect back up, but it'll do it even if it's still locked. |

OK ya you're wrong. When you wake the device and it's displaying a Cellular data symbol it was connected to a cellular data network plain & simple. When on a wi-fi network the iDevice should stay on that network until the signal degrades to the point of dropping the signal and switching to a stronger wi-fi signal or cellular data signal.

I don't believe this is so, since there are functions that are designed to occur only when the phone is locked, powered off and connected to WiFi. |

No I'm not wrong. When the device is in Sleep mode AND NOT PLUGGED IN, it'll drop off WIFI and back to 3G or whatever other cellular signal you're connected to. It's like this by design. |

Like I said above. The requirements for WIFI sync to iTunes, etc. all require that you're plugged into power. When an iPhone is plugged into power, WIFI remains on when the phone gets locked and goes into Sleep. When unplugged from power and locked/Sleep mode, WIFI gets turned off and it's back to cellular only connectivity until you wake it up, at which point it reconnects to known WIFI networks in range that it's been connected to before.
This is how the normal behavior is. The defining variable here is having the phone plugged into a power source. |
