Then how do push notifications work just fine on WiFi-only iOS devices like iPads and iPod Touches? They seem to come through in a timely manner whenever they are triggered, not just whenever you wake/unlock the device yourself (or stop streaming something, like YouTube or music).
Got a tip for us?

Wifi disconnects when locked

Not necessarily. I've read it here and experienced it with my parents' iPad mini Wifi: iMessages will not go thru unless they are using the iPad and for a very short time after locking the screen. Very annoying if I'm trying to get in touch with them.
Yeah, this is a bummer for my work WiFi which requires you to re-sign in every time you disconnect. At home it's no big deal since it reconnects instantly when I wake my phone. Push notifications still seem to come through on time for me even with cellular data off.

I stream music to Airplay speakers all the time, and even when the screen is locked, music still plays, so that means mine doesn't disconnect from Wifi when locked if music is streaming.
I don't notice any problem with Wifi disconnection when the screen is locked. I guess if no data is needed, disconnecting from Wifi network when idle is a good thing.

Well, I don't have a cellular data plan but the push notifications always show up when the phone is locked
Although I have no idea of how this works in iOS, there could be a clock-triggered interupt mechanism that connects to the network periodically.
Similary, a phone cannot keep its connection to the base station all the time. It does so periodically to save battery.

Haven't come across that using a couple of different versions/generations of WiFi-only iPads over the last few years.
Sorry to bump this year old thread but I found this thread searching for an solution to keep wifi connected after the lockscreen has gone black and didn't see it answered here. After pouring through many Cydia entries, I found a tweak called "Insomnia" that keeps wifi connected regardless of the state of the device. It also apparently doesn't let iOS auto-close apps, but I've yet to confirm that behavior.
So, that does mean that the only solution I'm aware of requires the user to be jailbroken.
BTW, I will post back here if I notice that keeping the wifi connected constantly has a significant negative impact on my battery life.

Update the firmware on your WiFi base station.
I know at least two people who had this issue, and it was fixed with a firmware update.

No, iOS is programmed to disconnect from wifi when the screen has been off for "x" amount of time. A lot of people don't like that functionality because when the screen is off and notifications and data coming in and out from various apps occurs, it uses your cellular data, which eats away at your cap. For people with a 500+ MB/month data cap, that's not a problem, but I have a 250 MB/month cap (because I'm painfully cheap), so it sucks to waste precious data when I don't have to.
How does that work with WiFi-only iOS devices like some iPod Touches and some iPads?
I would venture to guess that the firmware is specific to the device and if it doesn't have a cellular radio than iOS probably doesn't turn off the wifi radio, or it turns it on in the background every so often in order to receive push notifications. I've definitely awaken my wifi-only iPad after a long sleep before and noticed a split second before the wifi icon appeared, whereas when I wake it after just a short sleep, the wifi icon is already there as soon as the screen turns on.
It should hold on to your wifi for a few minutes, if there is nothing going on, it will disconnect.. If any message like in whatsapp pops up, it will reconnect ..
In my experience with my iPhone 5 running iOS 6.1, it holds the wifi signal for about 1 minute, then disconnects. In my experience, even if data is going in and out in the background, it will not cause the wifi to reconnect, and therefore even if I'm at home or at work, I am burning up my data allotment needlessly.
Maybe this is fixed in iOS 7, but there's no way I'm willing to upgrade in order to find out. I'm perfectly happy using Insomnia and it doesn't seem to be having a significantly negative effect on my battery life.
Well tried it out myself... On ios7.1.1... When cellular is on.. Wifi stops when're phone is idle after 1 or 2 min and doesn't switch back... But when cellular is off, wifi doesn't go out till the next 6-8 min(didn't try more).. Well that's on iphone .. I think it works diff on iPod touch...
