Best wi-fi performance?! - HD Mini General

I discovered this option within the Menu Connection Settings - it seems you can boost the wifi. Could someone explain why you would really need to do this?
My Wifi seems to connect fine to all access points.

The phone needs to communicate with the access-point (AP). If the AP has enough power to communicate with the phone, sometimes the phone needs to increase the power (signal) for keeping alive communication with AP. The communication is bidirectional: AP send packets to phone and phone send packets to AP.
It depends on environmental conditions (walls, distance to AP, ...)

Magic! Thanks for explaining ci6i!

Any reason why some phones don't have that option (GALAXY S for instance).
And the question of course: is there a way to enable that option if you don't have it?

Galaxy S is an android phone and Samsung!
This is a HTC HDmini section...!!!

Just out of curiosity does this in any effect tethering? I'm assuming it's an HTC option (I have a Inspire/Desire didn't find this on our thread) to increase performance but is the option more tailored for receiving data from the AP only or if the phone is AP would I get a performance gain (range, speed)?

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!

Seamless Handoffs between GPRS and Wifi Possible?

Are there any networking applications that would allow seamless switches between Wifi and GPRS/Edge?
It would be nice to be able to have a GPRS connection on the way into work, perahps streaming internet radio and then to have the network connection detect the Wifi and then switch. I suppose you would have to preconfigure your device with a list of access points, but considering that most of us use our devices at work and home, that should be easy to setup.
Or am I asking for something technically difficult to do?
YEs, Yes you can, but it maybe more trouble than its worth..
Its possible, Im not sure how "seemless" the transistion is going to be. First, you need to turn your Wifi slider to Performance so wifi radio stays on and scans while the PDA is sleeping. Then you need to add the SSID's (and WEP keys if applicable) of all the access points you intend to switch between. Having done this, you're going to need a huge battery, because leaving wifi on on this mode usually only yields about 3 - 3.5 hours of battery life. In addition, your GPRS radio is running so your battery life will be consumed slighly faster. With this configuration I have my work private network access points (3 for the different departments). My home wifi AP, and a few hotspots that I frequent in the evenings. When wifi is on, I can walk between any of these locations and the pda will automatically connect me to the present network. The downside to this is that every time I pass another visisble hotspot, the Universal chimes and wakes up to alert me to the new connection options. I also recommend doing the 802.11G hack for more compatibility (no speed improvement). Hope this helps.
Really seamless handover between GPRS and WIFI is not really possible without some firmware/radio stack changes. As long as you can put up with a second or two of data interruption there might be an 'seamless enough' solution in software (i haven't found one though).
There are some new phones which can do this handover for the voice channel (so called 'UMA' phones) but even then I have only seen the handover work seamlessly one way (wifi-to-gsm) in practice.
I can't see MS adding UMA support for some time (Motorola and Nokia have some phones that do this already). It nay be that a 3rd party adds UMA support but it won't be great as it needs to be embedded in the OS for best usability.
Google "UMA mobile phones" for more info.
It is possible to have seamless handover between GPRS and WIFI without firmware/radio stack changes ! The technigue is Mobile IP. But the provider would support/provide it or you have your own Home Agent server ( like proxy server)
You have only one IP address and your connection session is never abrupt during WIFI <-> UMTS Handover.
The other problem is GPRS/UMTS connection-hooking on MS Windows CE !

why live messenger not using the WiFi connection????please help

i am using the live messenger and connected to the internet through WiFi but it refused to use this connection and connect through the gprs.....please help
did M$ do a favour for the operators? I've experienced this, too...
If phone is switched off in the conn manager, then it's able to use the WiFi connection.
It favours the GPRS connection because the Windows Live services are designed to stay connected while you are signed in. Something that would not happen with WiFi as you can turn your device off, or lose the WiFi signal if you moved out of range and so on.
I am under the impression that it will use WiFi if available, but it will always use GPRS to maintain the connection. Not sure how true this is though as I haven't looked at it with a data analyser.

not working with me too through ActiveSync connection
Not a cure for the problem. But this allows you to disable your GPRS while you are on WiFi
http://www.modaco.com/New-FREE-Utility-t246171.html
On mine I just press cancel when the gprs connection pops up and it uses wifi after that.
They talked about it on one of the WM blogs. I can't find the link at the moment, but they said it was because the WiFi chipsets used too much power for always on connection so they forced it to use the phone. Apparently the phone chipset can be in low power mode but only power up when it receives data but the wifi chipset couldn't.
I found that even clicking cancel connection, it would keep trying to connect until it got through, then it would always send data over the phone.
On the other hand.... the reasons they gave for not allowing activesync over wifi were that it would be "insecure".
so there you have it... it's not allowed either because they are trying to save your precious battery... or they are keeping you safe and protected from the nasty people out there.
or it's a big conspiracy.

Turning off wifi after inactivity

Hello,
Is there some program for windows mobile 6 standard that will let me turn on wifi automatically when it is needed (by an application) and switch it off after its been inactive for a little bit?
ivan
When the machine is suspended - either by pressing the power button or after a timeout, the wifi will be off automatically.
Unless you want to have power on full-time....
I meant that I wanted to have wifi turn on automatically if an app needs network access, otherwise no. The fact that the phone turns on wifi even if you are just checking the clock makes it a bit annoying to leave it on. Nokia phones, for example, ask you when an application needs network access if you'd like to connect. After you close the application, the connection is closed as well.
What you described is dial on demand. But Wifi in WM nor Windows PCs as a matter of fact, is a LAN device that just doesn't "dial". It just connects as-is, like a physical ethernet adapter. In other words, you can't even do it in Windows PCs.
However, you may be able to use some profile based solutions to switch on/off your wifi base on time, location, etc. But that may not be what you want.

I guess nokia figured it out first then
or actually symbian?

WiFi not swapping between Access points

Hi Guys,
I am working on boat and we have multiple Access points setup around vessel.
My phone connects fine to any of them but when I move location it just stays on the original AP it joined and doesn't roam between them and stops working - If I disconnect and reconnect it works fine again...
Is there anyway of making the Wifi more aggressive so it will join the strongest signal AP?
Thanks,
Andy
Are all the APs setup with the same SSID/WPA? That's how roaming would work but if they are:
Boat1/WPA1
Boat2/WPA2
The phone sees them as separate networks and will hold onto the one you first connected to then it will "let go" once it's no longer available. So if it's setup as my example, tell your IT guy to quit being a retard and do as I command him to. -
If it is setup "properly" then i'm not so sure whats the issue. I would assume it's set up with all the same stuff to help make it easier for customers/clients to access the network with the same password all the time.
Or is it an OPEN network which directs you to a website to log in?
In your advanced wifi setting try checking "avoid poor connections". See if that helps it to switch.

Hey, all the AP are setup the same the phone just isn't swapping between them, it just stays on the one it originally connects to. I have no issues with my laptop or old desire they both work fine on board.

I tried that, no luck
I am running Matr1x kernel, could that have anything to do with it?
There's an app called 'Best Wifi' that I've been using. It will switch APs if the signal drops below a certain level.
Hope that helps!

Thanks Johnny, that app is working
I'll give best wifi a shot, I've been having the same problem since I got the phone and my solution is just to toggle wifi.
If you're AP's are WPA 2 Enterprise with authorization, Android devices have problems switching between them.
I just want to report back that Best WiFi has been working for me.
2 APs WPA2 Personal
WiFi doesn't have seemless AP pass-off like cell tech, even with Best Wifi, if you're on a VOIP voice call and you're moving between APs, you'll lose your call when it switches between the AP. It's a limitation of the technology.
