Powersave & Wifi

Dear all,
I'm wondering about Wifi telephony on the QTEK 9100.
It works fairly well with various software soutions. However, the phone has to stay "fully on" (except backlight) in order for th Wifi connection to remain up. This alters battery life severely.
I'm wondering if it is possible to have the Wifi connection stay up during power save mode, with some kind of "Wake on WLAN" event that would wake up the phone so that IP phone software can process incoming data.
Some of it already happens for GSM. I'm wondering whether the GSM part is "fully independant" (like on a different processor), or if it's handled by the main processor. In the later case, it may be possible to achieve something similar with Wifi telephony.
Thanks in advance for any hint.

so there is no way having WIFI enabled and lettign the pda go to sleep mode / power save mode ??
is there an APP that leaves power save mode off if the WIFI is enabled, so only the screen goes of light, and the pda stays on ?
P.

It's fully independent. It's very cleverly written; this is why, for example, listening to incoming IMAP IDLE or Push Mail callbacks don't require the CPU at all.

yes i got that part on my own, thats why the GPRS connection stays on... but still there should be a registry somewhere to prevent device to go to sleep if WIFI conneciton is made..
tried all the powermode stuff in regisrty, nothn worked... out of clue...

I don't think you can do this - the WI-Fi module is completely independent of the radio module. Furthermore, you'll constantly need a LOT of power to keep the Wi-Fi connection up, as opposed to GSM/GPRS, where handshaking is only done during roaming to another cell and/or every (AFAIK) 10-20 minutes. Otherwise, the PDA doesn't trasmit anything, a sopposed to the Wi-Fi case.
That is, it seem sit's impossible to do any long-term Wi-Fi "listening" in the current Wi-Fi / PPC architecture.

all i need is a tool that disables POWERSAVE mode if WIFI connections is made, or even if WIFI is enabled...
that would do all the work....
anyone ?

i think the closest thing is in phm powertoys (http://www.phm.lu/products/PocketPC/PowerToys/)
the screensaver option... what it does is turn off your touchscreen like in "sleep" mode but if u use this you might want to disable the power save option cause while u have screensaver on its still gonna count down n shut off ur ppc hope this helps!

Disable Wireless Going to Sleep

Hi All,
I have carried out a search but not managed to turn anything up :-(
I am trying to stop the wireless from going to sleep after whats seems about 5 minutes.
Can anybody help?
I user the KaiserTweak function on my TyTn II and that works great
Thanks, Andy

Try Settings>Connections>WLAN>Power Mode tab
Uncheck "Auto turn off WLAN if not connected"

Hi Techntrek,
I have already tried that.
The application that I use polls a web server ever one minute so the Wireless is being used, it is just disconnecting because the device is not being touched key/screen wise.

you are probably talking about the screen/sleep settng, different setting. settings>system>backlight>both power tabs

Connect to WiFi network timeout?

Hello. I'm sure that this must have been discussed but I cannot find the answer using search. As is surely normal, I use WiFi within the home and GPRS when there is no WiFi available. If WiFi is connected and I go out for a short while, then when I get back in a WiFi area, the WiFi is still connected. However, if I go away for a long time, and GPRS is used for perhaps a regular weather update, then the WiFi disconnects and has to be manually reconnected upon return to home. This leads to GPRS being used in a WiFi area unnecessarily if you forget to re-connect WiFi. Is there a WiFi connection timeout value or any other setting that can be changed? My old TyTN II did not have this problem. Thanks.

Try this CAB
It disable disconnecting WiFi when phone is in sleep mode and with this phone automaticly connects to WiFi when Leo will be in range.

Thanks Franq_23_pl. I think that the CAB just stops WiFi disconnecting when the device is in sleep mode. That will just drain the battery, surely? My old TyTN used to disable WiFi when in sleep mode, but as soon as you switched it on again, WiFi would be enabled and it would connect if in range. The problem with my HD2/Leo is that if I am away from my WiFi for some considerable time (ie, most of the day), then when I get back home and switch the device on, WiFi is disabled, and I have to manually toggle in on. So my question is..... What are the circumstances that cause WiFi to disable itself, and Is there some way of stopping it happening?

OIC now. I think you having some battery saving app and this app turning off WiFi when iz not used. What apps or registry mods you have installed on Leo?
You have the same behavior after hard reset?
My Leo don't disable WiFi. When i go outside (for ex to work) and back after few hours my Leo connecting to my home wireless network automaticly.
I remember, that i had the same problem like you and it was caused by app, which had duty to save battery.

Smart mode for Wi-Fi broken or dumb?

Does anyone know the specifics as to how "Smart mode" for Wi-Fi works? by default it's turned on and I remember when I first got my device that Wi-Fi would turn on on its own when I was home. It would also turn on at work and despite turning Wi-Fi off at work it would turn itself on again. Does "Smart mode" require GPS and/or Location reporting to function properly? Are there any alternatives?

from my understanding (which maybe off) the smart mode will remember and recognize any previous wifi's that you have on your list and then when in range it will attempt to turn on wifi and connect to them.. what this leads me to believe is that it will be scanning ALL THE TIME for them in an attempt to turn on and connect, (because I had my location off so I don't think it uses GPS).
I had that "problem" where it would keep turning itself on and I didn't want that or want it killing my battery for a weak wifi connection, so I just turned off the smart mode to "fix" it.

so in other words Location reporting is necessary for thisbto work? while I have Smart mode on, I do have Location reporting off and for the most part it hasn't been turning on wi-fi scans anymore. wondering if turning Location reporting off when the screen is off makes Smart mode less effective...

sorry for the delay..
i'm not sure its needed.. I don't have mine turned on, I just had the smart mode on and it would turn the wifi on as I came into range. Which leads me to believe its constantly scanning. I could be wrong but that's the only conclusion I can draw unless I'm missing something.
are you saying that your wifi will not turn on if your location is off?

For the most part I've always had Smart mode on since it was on by default, however it's only recently that I've used Tasker to disable the Location Reporting when the screen is off... it's been a while since my wi-fi has turned on by itself and for the most part it's the only thing I can think of that I changed in relation to locations and wi-fi. I know there was an app on the BlackBerry that would turn on Wi-Fi based on location using cell tower locations and claimed that it didn't use any battery since it wasn't firing up the GPS or constantly scanning for Wi-Fi. This may be how Smart mode works except that it's reliant on Location Reporting. I suppose at this point in time my guess is as good as yours as to what/how Smart mode actually works.

WiFi won't connect to know Networks when screen is off

As the title suggests, my phone will not connect to known WiFi networks if I do not wake the phone myself.
Image being away from home, having both mobile data and WiFi enabled. The screen is off throughout the whole time and when I reach home it is supposed to connect to my WiFi. Instead, it connects to my WiFi only if I wake the phone. If I leave the phone sleeping (standby) it will stay on mobile data, unless I wake the phone myself.
Is this regular behaviour?
PS. The phone has not problem retaining connection to WiFi networks when sleeping. It just won't make a new connection even to know networks.

There is a setting in wifi settings under advanced where you can change how and when the wifi must be on/off.

If you mean "Keep WiFi on during sleep", I have it enabled already!

Have you played around with power saving settings?
