Keeping WiFi alive doesn't work anymore!

I set up the WiFi standby rules to "never", so wifi should be always on even when my device is in standby mode.
This worked very good at the beginning, but since some days WiFi is NOT kept alive. As soon as the device is going into sleep mode i will lose WiFi connection. The WiFi standbye rule is still correctly set to "never".
Thats really lame because i use locale to update my RSS Feeds at home over WiFi on certain time slots. But i get no updates since wifi is not active when the device is sleeping.
Anybody an idea what the problem is? As i said it worked for 2 weeks and suddenly its not working anymore.

Won't that drain the battery to Kingdom Come if you do leave it on on standby? I used to do that on the Tytn II I used to have, and the battery died after 2 hours!

well i wouldn't say 2 hours, should be more than that. But i'm only activating wifi at home, and at nights my device is plugged to ac adaptor. So battery is not an issue in my case, and i want to use the better bandwidth at home. I just dont know why is suddenly stopped working...

Settings > Wireless controls > Wi-Fi Settings > Menu > Advanced > Wi-Fi sleep policy. When finished press Menu and then Save. Done.

The "Menu Button to save" Hint did it! thanks!
I always chose the option, but forgot to save via menu button and pressed the back button.
The strange thing here is: when i was coming back to this menu later it would still show the correct setting (WiFi always on), even though i hadn't saved it via menu button. But it wouldn't work, because wifi would be deactivated.
The back button will save your last selection, but won't activate the option!
This is really one of Androids problems: you just don't have one standard way of interacting with the system on many levels. Sometimes "back" button is enough (or the only way) to store your data, other times you have to press hardware buttons to save...

hmm the problem seems to be elsewhere: today in the morning the connection was lost again when i took the phone out of sleep mode. i could see the wifi icon, but the apps couldnt connect to the net (my rss feeds hadn't been updated).
Seems like each time i deactivate wifi manually (when leaving home) the wifi rules settings will be lost, and i have to change the wifi rules again and save the settings. Otherwise wifi won't be kept alive...that's really annoying.
maybe i have to download the "keep wifi alive" app after all from the market...

What make and model is your AP?

it's a netgear router, i will check the exact model today and post it here.

hmm i forgot to check the model, but i changed my router settings yesterday.
the router was set to disconnect after 60 minutes, when the connected device is not using the connection.
i changed that, so the connection is not reset at all, but still as soon as my device goes to sleep mode the wifi connection is basically dead.
After taking the phone out of sleep mode, i can see the "wifi connected" icon still there, but no app has any internet connection.

Wifi wont turn off in sleep mode

Hi Guys,
I got my HD2 today and i have to say i am impressed!
I only have one problem which i am not able to resolve.
When i turn on WiFi, it wont turn off during sleep mode (when i turn off the screen). i need to manually turn it on or off. this is how it came out of the box.
I wonder if other HD2 users are having the same problem / found a solution?
I tried advanced config tool, and i unchecked the "wifi during sleepmode" setting, but after each reboot the settings just come back.
Any help would be appreciated.

Hi mate, you should look this

I thought that guy just want to keep WIFI on but you did.

thanks man but it does not help me with my problem. I cant seem to be able to get WiFi to auto turn off when in standby. the reg tweak will work until you reboot the device. after reboot the WiFi again won't turn off when in sleep mode unless I manually turn it off.

Bump.
Can any other HD2 owner please confirm if this is happening on his device too?

Same problem.
HDtweak and AdvanConfig does not work. After soft reset, wifi-on-standby is back ON (checked).
Been trying to find a Auto-Disconnect for GPRS(HSDPA) but the above 2 apps does not work too.

have you tried to change wifi power settings to high? I think it does work then. I guess the medium setting is something special...it keeps the wifi connection alive in standby, but also doesn't consume much power. I have an exchange connection active, so i always need an internet connection. The moment i turn on wifi at home, it stays on, even in standby, and my data connection over 3G disconnects. My exchange still works perfectly...and no huge power drain! My wifi power setting is on the medium setting...

Yes, I can confirm I'm encountering this issue too - on my HD2.
Strange, 'cos I wasn't at first, I'm sure - I remember the wi-fi notification icon flashing when resuming from sleep.
glenner05, can you confirm that you can get wi-fi to sleep please?

Hmm.. thought it might be connected to the htckeepwifionwhenunattended registry value but mine's set already to 0.
There're others trying to do the opposite!

Anyone else found a solution?

I think HTC made this by design. If you turn GPRS data off and leave Wifi on while in standby you will be surprised how low the power utilization is.
I tested and with GPRS data off and Wifi ON, in standby you lose about 2% battery per hour...that's nothing.
It seems that on the HD2 the Wifi power consumption is really optimized so no real need to turn

Mine is on default Wi-Fi settings and when it goes into standby, wi-fi goes off.

Yeah goes of in sleep mode, if you get wifi toggle, you can choose to keep it on or turn it off when you like .
Shame the grps is still a problem....

pgamble and jrvenge: you really mean wifi switches off on the device when it goes to sleep? Ie. you see it disconnect from your router or something?
jrvenge: what did you mean by, "if you get wifi toggle"?
clubtech: when I read your post I agreed with you, maybe. I can't now be certain I remembered correctly that I'd seen wifi reconnect. And yes, the power consumption does seem low

There is a cab floating about here that enables you to force the wifi on always or turn it off.
If you forc on it stays on, if you turn of it goes off.
Return to normal and the hd2 does its power saving thing, so im all sorted there, just need a timeout on the gprs now.
If you cant find it let me know. It works a treat.

can youplease post the cab ? I have been looking for something like this .

Sure pm me your mail and i will send it

GPRS Disconnecting software here fella's, tested and working on my HD2 100%
May also turn off wifi but i've not loked yet, just about to leave for work so will check later!! lol

Ok just tried and it does not do what we want with WiFi

Yes ... if device goes to standby, when it comes out .. you see wi-fi searching to connect again ... so it definitely disconnects and the reconnects when it comes on again.
Paul.

Yup your right!
If it's in balanced or best battery mode then it turns off in standby and reconnects/searches again when you press a button to bring up the lock screen.

Wireless on when standby

Was wondering if its possible to keep the wireless still turned on when the phone goes to standby. As in 3G is always on, thus always giving me new emails

Hmm #33 may be able to help you?

Easy....
Download Shap's Advanced Config Tool. There is an option to keep the Wifi on even when the phone goes on standby.
Once Advanced Config Tool installed, launch it, go to Menu/More settings/connections/Enable Wifi on Standby.
also I would recommand you to download a basic freeware named ScreenOff (by Applied PDA software), and use it to turn off the backlight without turning off the Wifi.

I've always having trouble to maintain the WiFi connection whether it's using battery or AC.
I've installed the Advanced Config Tool, the "Enable WiFi on Standby" indicated already enabled. Then I used the ScreenOff. After about 10 seconds, the WiFi connection was lost as I verified it by pinging the HD2 from a PC. It's plug into AC all the time.
However if leave the HD2 just "dim the screen", that seems to be the only way to maintain the WiFi. Obviously set it not to go into standby after 30mins (the default value).
Are you able to maintain the WiFi on HD2?

Yes. No problem here.

when you go into wifi advanced settings you can select power mode. when you set power mode in the medium setting, wifi keeps connected even in standby! and it also doesn't drain your battery while in standby. just try it. first select high power mode and turn phone in standby. wifi connection is lost. when you turn it back in, you will see wifi connecting.
with power in the middle setting, turning phone in standby keeps wifi alive, with very low power consumption. and when you turn phone back on, you will see that wifi is already connected.
i use wifi all the time when at home. my data connection is turned off. and still my push mails are recei ing through wifi!

Not that easy, I tried all power modes and in all occations it whent of after 1 minute (ping timeout). Weird that all roms behave so differently

Speaking of pinging your HD2... when your wifi is enabled and IDLE, what ping results do you get?
My HD2 acts very strange. when my wifi connectivity is on & IDLE (no data activity, device is not in standby mode), my ping results vary from 50ms in average to 200+ and sometimes I'm experiencing even higher spikes of 500ms+.
I have tried to change the wifi's adapter power scheme to "best performance", but it doesn't seem to change something.
However, as long as there is an activity, my ping replies from the HD2 seem to be fine (less than 15/10ms).

seems like some powersaving feature... when idle, why should the wifi chip work at top speed.. just like cpu scaling....

my power saving slider is in the middle and still when the screen goes off and I switch it back on the wifi is reconnecting.

Have you done the ping test from another PC/laptop on your network? Wait for about 1 minute after the screen is off and if you still can ping your HD2, I think it's probably your push mail somehow manage to maintain the wifi connection. I might try that if that's the case as I've tried absolutely everything else and so far abosolutely nothing can keep the wifi constantly on if the screen goes off.

i can still ping it after a few minutes... what you say about push mail and keeping wifi on makes sense... first thing i do when configuring my phone after fresh install is setting up my push mail... maybe that's why my wifi is always on.
You could set up a free gmail push account?

I'm not sure if my problem is related at all but my wifi only seems to connect to my router when it's diconnected from my PC. I'm sure before I upgraded to 1.48 ROM it stayed connected. Any idea guys?
oh, and I've only ever had it in the middle power saving mode and it looks like it does disconnect when it goes into standy.

I've set up gmail account as well nut as far as I know it's just IMAP or correct meif I'm wrong. if It's not push mail, it'll still kinda polling isn't it? what's your view?

Good news guys, I've finally managed to get the WiFi to stay on even after the screen is off. Yes the trick is the "push mail". I deleted my original gmail imap account and set up a Microsoft Push Mail based Gmail account. Then did the ping test and it's staying on for sure now. But I did notice that it'll have 1 packet drop occasionally.

wifi disconnecting in standby
my hd2 stayed connected to wifi in standby, then i applied a few tweaks and .cabs, i had a few little issues like the screen freexing and not refreshing so i did a hard reset, since then wifi wont stay connacted when the phone is on standby, it is confusing

Hi I found a solution. Just install this cab. No soft reset needed

[Q] Hibernate/Standby Mode

Is it possible to have a Hibernate/Standby mode on the Transformer? Not just a screen off setting. I am used to putting my netbook into standby, hitting a key, and everything ready to use within a few seconds.
With the current screen off setting, the wireless stays on, I stay visible on gTalk and messages end up going to my Transformer instead of my phone. Also, I would think battery life would be increased.

I would check your settings as my wifi disconnects when screen off
settings located
Wireless & Networks
Wifi Settings
Wifi Disconnection policy
mines set to When screen turns off
Not sure about Hibernate state on android at all others may know

Did not know that. I had just been turning wifi off because I noticed that even withe the screen off it was draining the battery faster with with with wifi enabled.

[Q] Bluetooth GPS Disconnecting when screens off

Running a Nook Color with CM7.1 stable. Kind of an odd issue here, I have two different Bluetooth GPS devices, and when they are paired to the Nook and I turn my screen off and then back on, it loses the connection. The only way to reconnect the devices is to restart the Nook, as it fails to connect after the screen is brought back up. I have found that if I have the Nook plugged in for power, this issue does not happen. I have tried multiple GPS apps, reflashed CM7.1 multiple times, but still have no success unless I have the Nook plugged in, or I just ensure the screen doesnt go to sleep.
I really need this to work, as I'm using this as a pilot, and I can't have the screen on the entire flight as it will drain the battery quickly. I swore it used to work before, but I know I had issues with it, and maybe now realize what was causing those issues. On a side note, my friend has also tested everything I have done, but his works consistently and reliably regardless if he leaves the screen off, or turns it on and off repetitively. Hopefully someone may have an idea!!
Thanks in advance.

So noone has any thoughts or ideas at all?

Well seeing as it doesn't happen when your plugged in that would make me think that it has something to do with the fact that WiFi turns off when the screen is turned off. The Bluetooth and WiFi are on the same module i do believe. The default setting for WiFi is to stay on all the time while plugged in and turn off when the screen is turned off while on battery.
My suggestion would be to turn the WiFi to stay on all the time and see if that changes anything. Go to WiFi settings --> menu --> advanced --> WiFi sleep policy -->never. That would be my suggestion, hope that works for ya!

That's what I was thinking too. It seems that when NC goes into deep sleep Bluetooth will lose connection. By removing deep sleep you should be able to stay connected, although your battery will drain faster than with deep sleep on, it should have a better life with screen off than on.

Well I appreciate both of your responses. However, I should have mentioned that I do already have Wi-Fi set to always stay on/never sleep. Any other suggestions?
