    I thought I saw a fix for wifi sleeping over on XDA the other day. I'll go look for it and post it up when I find it. brb

    EDIT: Here's the thread I was referring to: http://forum.xda-developers.com/show....php?t=1707651
    Requires root, and read the whole thing before flashing. It's kinda confusing.

    Anyone want to be a guinea pig and try this out?

    i know on my photon it would do that. I had to change the battery setting to not use power save mode so that the wifi would stay connected.

    That is quite possible- a friend at work with a Motorola said the same thing. There is no such option (that I can find) on the HTC phones. But none of the other HTC phones have ever acted like this (well, at least not the other two I have had).

    I am not aware of any such option. There is an option under Display called "Stay awake: screen will never sleep while charging." But that is not the problem reported in this thread, we are talking about WiFi disconnecting during sleep, not during awake. I have no problems with WiFi staying connected when the phone is awake (screen on) or even for short ( minutes to perhaps up to an hour) sleep periods.

    Not sure I believe you... You are saying that you left the phone asleep for hours, and when you turned it on and immediately looked at the top of the screen, you showed a WiFi icon that was on, solid?

    Please go back and reread the first posting. Especially the part that says:

    * The default setting of "Keep W-iFi on during sleep" is active (set to "always") and I have never changed it.
    * All WiFi settings are set to stock/defaults.

    Yep, I see the same behavior. Somehow either that setting is not setting what it is supposed to be or it is being ignored. Either way it is a bug.

    Try factory reset your device maybe and see if it fixes it. I've never had any issues with mine.

    It reconnects so quickly that you might not be able to see it.

    How I found out that mine was doing it was at work; every two hours or when you disconnect from my employers wifi, you need to sign in to reconnect. Every time I woke up my EVO, I was having to sign in again.

    Could that be your employer security settings?

    That could be the security setting of the WiFi I do not have to reconet to my WiFi that is how I know it is not disconnecting

    I was having all the same problems reported in the earlier threads with the Wifi disconnecting when the phone would sleep, but I think I found a solution that works for me, which was to change the wifi band/frequency selection under the Advanced Wifi menu from "Auto" to 2.4 Ghz only. Now my phone never disconnects during sleep, based on downloading podcasts & Play store updates (which would be interrupted before once I put the phone down)

    I currently have a dual-band router at home (airport extreme) with both bands (2.4 & 5 Ghz) running, and my office uses an older single-band G router on 2.4 Ghz. I noticed that the disconnecting would only occur at home, and not at my office, so my guess was that the phone was disconnecting somehow when it switched between frequencies at home.
    A software bug is somehow preventing it from re-establishing the connection properly if it switches frequencies until the phone "wakes" again.

    Not sure if this is the real solution, or just unique to me & my setup, but for those of you with dual-band routers, give it a try. Just pick one of the frequencies after considering all the locations you use wifi, since you will not be able to connect if you pick 5 Ghz and you go someplace that only has an older 2.4 Ghz router.

    I still think this is a bug though, since the phone should be able to automatically switch between frequencies and re-establish connections even during sleep.

    No, as every other phone that I have used at work (as well as fellow employees) does not have this problem. I have used an OG EVO, Epic 4g, Epic Touch. A coworker had a Thunderbolt, and recently upgraded to a Razr Maxx, and doesn't have this issue.

    It does it to me at home too, I just wasn't looking for the signs of it until the issues at work. I don't really do a lot of heavy downloading with my phone; but I know that my battery life, while not horrible, would be quite a bit better if wifi wouldn't disconnect why sleeping since my cell signal isn't that great at home.

    I doubt my radio is bad. When it is on, it works great. Besides, there would be many people with bad radios if this were the case, because lots of people have confirmed this behavior now.

    That could be the security setting of the WiFi I do not have to reconet to my WiFi that is how I know it is not disconnecting
    ? I use security at home (WEP128) and no security at work. It behaves exactly the same on both- it will disconnect after long sleep periods and reconnect in a few to several seconds on either when woken up.

    I don't think this is it either. I have a single band router and work and at home.

    Wow I think you might have just hit something interesting!

    * How the hell did you find this?
    * If this is so well known that there is even an app for it, why did the HTC support staff and "engineering" not say anything?
    * What is so "Smart" about "Smartsync?"
    * What troubles me the most is that the description does NOT match what the phone does. Mine does not disconnect just between 00:00 and 07:00am.

    I will try it and see what happens. Here is an xda link: http://forum.xda-developers.com/show....php?t=1708492
