Dear All,
Appreciate your helps in advance. Android default email client when connected to office wifi doesn't sync my e-mails while if i configures my exchange account in enhanced email it works absolutely fine and all my emails starts syncing on same office wifi.
I was having an offline chat with my system administrator and he told me that they have blocked something to avoid IP pool full issue ( new users were not able to connect to office wifi as almost everyone was using two IP, one on smartphone and one on laptop).
Question is how enhanced email client is able to sync? Can i make some changes in default android email client to make it sync.?
My Edge connection is too slow to download emails and can't switch to 3g as it is a company provided connection.
Hope i am clear.
Devs please help. I badly need this.

Hi,
Try This.
Go to the global Sync settings in: Settings --> Data Usage --> Menu --> Auto Sync Data
Also about that blocking thing that your system admin is doing.
Instead of blocking devices from connecting through wifi,
Why don't he/she just add some more subnet on the network to cater everyone's devices.
Possible if your company's network devices are capable of certain configurations. (Expanding such network)
Or maybe it's just that your system admin really wants to limit the use of internet connection by allowing just 1 device per employee
Just a thought.
Hope i got you correctly.

It is already enabled. Device can connect to wi-fi for normal browsing but e-mails are not being synced.
Since most of websites are blocked in office , hence generally people don't connect only to surf .
Guys please help.

Did you try to log in to your wifi from your phone when the computer is off. My phone has trouble connecting when my PC is also using the wifi, and this is because of the way the IT Dept has set it up.

The only time I have this issue is if my computer is connected to the wifi first.
I would try a different email client, since you have been able to get this to work with the Exchange Client, maybe the issue is with your default email client. K9 mail is one of the most popular clients and I believe it is free. I have used it before and I was able to use it to connect to my work and home wifi with out problem.

Here is the latest Windows Live CAB that I downloaded from the WM Marketplace today (May 3, 2010). I like it cuz it allows you to sync and push your Hotmail email even if you're already pushing Gmail with ActiveSync. In essence, it's like having 2 Exchange accounts. It also gives you the "conversation" style emails in Outlook.
Windows Live never used exchange to sync email, what you say doesnt make sense as you have always been able to use an exchange account with a windows live account. Plus the version on the MP is currently 11.1, this would be a downgrade.
Any changelog?
Even if it doesn't use Exchange to push the Hotmail, it's basically the same thing, so who cares about semantics.
Please kindly state what the full version number of this *.cab file is... I know that the latest one provided in http://wl.windowsmobile.com/ is version 10.7.0061.0500.2000.

There has been some confusion about which version this is. I'm just going to leave it with the date that i downloaded it from the actual Windows Phone Marketplace. If you find a CAB that was downloaded after that date, then it's probably a later version.
Hmm...
Actually, I also have always been able to use Exchange + Hotmail.
Since I got my Windows Phone back in October 2009, I've always had Gmail on Activesync PLUS Hotmail on Windows Live and both were set to Push-mode (As item arrives). Maybe there's another feature they introduced that we haven't discovered?
Have a version for Windows Mobile 6.1 Standard (Motorola Q11)? Hugs from Brazil!
Some ROMs don't come with Windows Live or possibly with an older version.
This CAB will allow you to push both Gmail and Hotmail at the same time.
I recently got a windows live/messenger account and now I'd like to use it on my i780 via Wifi (not via Gprs, as that is quite expensive). Could you please tell me if this version can do so? The older ones all seem to be unable to do it. (exept if there was a way to use wifi as a modem)
thanks in advance

Are you asking can you use Windows Live over a Wifi connection? The answer to that is yes.
A cool little feature I noticed is that if you are using a ROM that does not have threaded email conversations, installing this CAB will enable that in Outlook. A nice little addition.

Thanks for your reply, but in my case, it doesn't work. Opera mobile, Outlook mobile and any other program that needs an internet connection are able to use wifi, but windows live insists on using gprs. When I try to log in(with wifi enabled and connected of course), it opens the connection bubble saying that a gprs connection is being started. If I click it away a couple of times, a notice appears that gprs doesn't work...
I already made an empty isp in the connection settings to prevent it from using gprs, but it somehow seems to start ActiveSync on the mobile. There I have no option to change the connection type to use wifi, but only wap gprs or mms etc.
Btw. my mobile is running its original windows mobile 6.0 Pro. Could that have something to do with this?
sorry for writing so much, but I want to make it as easy as possible for you to help me.
Thanks again
Using Wifi to get hotmail seems to be a problem. It always wants to use the cell data connection over wifi if both are available. I know that you can get windows live email through wifi if you turn on wifi and completely turn off the phone radio as if you have no service. But if both are on, I don't know how to make wifi take priority.

you could try DataController or Modaco NoData to (temporarily) disable your data connections. That way Windows Live is forced to use wifi
One thread with all official MS apps is not a bad thing, but someone looking specifically for Windows Live will have an easier time finding a thread dedicated to just that.

I'm having the same problem of unable to connect messenger on wifi. Even when I disabled the GPRS connection, Messenger will say that problem connecting to the data connection.
hmm I maybe wrong to intervene and say try using Palringo which has all MSN, Yahoo, Gmail etc (perhaps you are using Live messenger for a reason there) -

Thanks for your tip, you're quite right. I'm going to give it a try tomorrow in the morning.
With windows live etc. I haven't been able to even only take one step further. It still always uses the connection that is chosen at "programs - internet access - network connection". If I deactivate this connection(i.e.with NoData), it simply tries another one and if I stop all connections (or simply turn off the phone part of my mobile), it immediately says that there is no connection available. But it does still not use wifi, although it's turned on all the time. It works via GPRS, by the way, but it's much too expensive.
Expect to hear from me soon
EDIT: I have now tested palingo and I have to admit that it works really good! Also, there were no problems with wifi (of course)
I am staying in a hotel abroad and have purchased some logon details for the hotel's wireless internet for my stay. However, whilst I can connect with my laptop, my S3 lists the network as 'disabled'. Wifi is on, and not set to sleep or anything like that. When I click on the network, it (very) briefly says 'saved' and then returns to 'disabled'. I have not even had the chance to enter my logon credentials, so that cannot be the problem. I have also tried to 'forget' the network and re-connect, but there is still no option to enter my credentials and connect on my S3.
Any ideas?
Thanks
Try changing your phone's mac address to your laptop's mac address.

If that doesn't work you could ask them for a new code and see if that will work with your phone. Or ask to see their network support staff (if the network is managed in-house).

Is there a voice / messaging app that will work via a wifi connection WITHOUT the need for an Internet connection? For example, two people with phones connected to the same router over wifi, but NO ACCESS to the Internet. I'm assuming apps like Skype would require both devices to be able to communicate with the Skype server to initiate the call, but might allow peer-to-peer afterwards.
I am not interested in making calls or texts to people outside of the wifi network. Does such an app exist?

without any kind of data connection, you cannot communicate to the other person. unless you are conversating in person or via us mail.

Do you understand the difference between the INTERNET and WIFI? It would work over WiFi, but not need a central server, nor would it need a connection to the Internet. If you knew the IP address for the other phone, for example, you could connect with it directly.
I don’t know if there is any local network messaging app for android, but I think it is definitely possible to write such app.
But even if there is no such application, you can always set up your own local XMPP (or some other IM protocol) server (visible only from local network) and use any messaging app which supports XMPP protocol. There are plenty of them.
I was thinking of something along those lines. I suppose the heavy solution would be to use a separate computer with asterisk, but I was hoping to find something with just the phones as hardware. The Android 4.0 software has wifi p2p built in, but I'd hate to limit the solution to that environment.
I did find something that seems to work, but is buggy and requires root access: Serval Mesh
This looks like an incredible project and I hope it continues to progress.
If anyone knows of something similar, please reply.

Wifi != internet... You can setup a wireless LAN to share files between computers / devices, without it being connected to the internet. WIfi is just wireless networking... external internet isn't required...

Try this as an experiment: cancel your service with your Internet provider, but keep the router with wifi. Why pay money for the Internet when you've already got wifi? It's the same thing, right?

Guys it is so funny to read your arguments about what is Internet and what is WIFI! You are all wrong as you need to read a bit about that!!!
WIFI is the mean of communications to the network no metter if it is Internet or somthing else and Internet is the global network that you use day to day without even thinking about what it is with all it's services and infrastructure!:laugh:
p2p video calling
Looks like the app ain't on play store any more. I found one app which allows only voice calls p2p over the wifi, but doesn't have the video calling option.
Anyone know any such app featuring p2p video calling too?

Hi,
I search over the forum but didn't find the answer to my question.
I'm the happy owner of a GS3 stock rom, not rooted, fresh out of the box.
It works verry well. I'm impressed by the device itself but I struggle with a problem.
My exchange account won't syncronize over 3G. Every few minutes, I get a message saying "unable to connect to [my account]"
gmail client works just fine but I have two email addresses (pro and home).
This is not a connectivity issue as other apps works great aover 3G and this is not a network limitation as I can connect thru other wifi networks.
I can do all necessary test and I had a look in all settings I can find without any succes until now.
I had 3 FW update since I own the device, each time I hope it will solve my probelm...
Thanks for your help.
Best regards from Belgium,
JC

I checked and I can find any exceptions (I can't find the options, to be clear). Under the Data Usage, I have mobile data and Wifi pages but I don't find any way to manage exceptions.
There is a similar issue with the hotmail app - SSL auth error on 3G - Fine on Wi-Fi
The way to resolve that issue is to uninstall the app - remove any accounts associated to it (the hotmail sync account removed authomatically) reboot the phone - then set everything back up BUT DO SO ON 3G and not Wi-Fi!!! For some strange reason this sorts out the issue and can then connect on both 3G and Wi-Fi.
This is obviously specific to the hotmail app - but as this is also email it may also resolve your issue - Worth a shot at least. .Good Luck

How can I uninstall the stock email app? I will try to clear my account but not uninstall the app and see if it solves my problem. I will try it tonight when I will be back in my country and not in roamuing anymore.
Thanks
I don't use the stock app at all - I guess you can remove the associated accounts under settings/accounts then go to app manager and clear cache and data.
My issue was due to a self signing certificate or something - guess that a hidden setting somewhere changes when you accept but wasn't working correctly when setting up accounts over Wi-Fi.
Hope it works for you. You not the option to get a specific mail provide app from the playstore? - Could be another option
I will let you know
I'm quite happy with the stock mail app for now. If I can solve my problem by reseting my account over 3G, I will keep it.

I resolved this issue by:
- deleting the Exchange Active Sync eMail Account I set up over WiFi (Email->Settings->Delete Account);
- created an EAS Account over 3G, selected "Accept every SSL Certificate" (Email->Settings->Add Account).
It seems that creating an EAS Account over WiFi prevents the same account to access the server over 3G/EDGE/... connection.
Tried on Sony Xperia Tablet Z SGP321, default mail app, with Android 4.2.2.

Hi,
I have also an Galaxy S5 Android and sinds we have Exchange 2010, it does not synchronize any more. If I put my phone on SAVE MODE, it doesn't work. If I DISABLE the SAVE MODE it works.
Go to Setting => Power saving => put Power saving mode OFF

Hi Guys,
I have 3 android devices (xperia s, htc one x and a galaxy s3) connected to a wifi network. This is kind of a protected network and there is a firewall involved. Also the devices are getting IP via DHCP. The problem is that i am able to access web site via browser but when i try from the application, its showing i don't have internet connection. There is no proxy configured in this network. There is an IP filtering in the router which filters the IPs starting with a particular series. But the web site and the application which i am trying to use are supposed to use this IP series.
I've come across issues with internet connections on mobile devices. This might not work for you, but it has worked for me in the past.
I assume your devices detect all of the settings you need automatically?
If so, you may need to manually change some things.
1) Check your IP and make sure it's set right for your network
2) Check your DNS settings. Sometimes the default ones don't work properly.
Try:
8.8.8.8
8.8.4.4
These are from Google's OpenDNS and have served me well in the past.
If all else fails, check the network itself.
Hope this helps

Thanks for the reply.. but as i mentioned earlier, the device is getting IP and other stuffs via DHCP. I am not allowed to configure something statically. It has to come via DHCP. But the interesting fact is that an iPAD in the same network is able to get internet in both browser as well as applications.
Hey, if you need to get settings via DHCP then you should talk to your network admin for the settings

I am getting all the settings perfectly.. hope haven't read my first post.. i am able to browse via browser.. the problem is with the apps.. that y am confused about.. i know this kind of a problem may arise when we have a proxy configured in the network.. but we dont have a proxy in the network.. in fact an ipad hooked up to the same network works totally fine..
Did you get your apps working?
Nope..still facing the same issue.. internet is available in browser. but not in the apps..
There is no problem with your phone. I am sure that changing your router will fix this problem. Try another router with your internet connection and tell me if that worked.
Press thanks if I helped you!
We have tried that as well.. The situation got little worse with the new router. Now Internet is not working with ipad as well. But it's working in browser for both ipad and android. Another thing I have observed is that the Web pages load blazing fast in a windows and blackberry but the same site loads very slow in android and ios. As I mentioned earlier, the network is having a high security with firewall and encryption. Is there any limitations for android and ios to work with these kind of highly secure network??

I think that the firewall is the main culprit. Try disabling the firewall if you can.

Hi - I was experiencing this on a Galaxy Nexus with no SIM card only connected to WiFi - on a WiFi router that used to work.
The solution was to
1. Open up DHCP settings on the phone (Settings -> WiFi -> My Network -> Advanced)
2. Manually set them to something that's wrong.
3. Save.
4. Set DHCP back to what it was.
5. Save.
May not work for you, but for me, after about 30 seconds the app store and other apps started working again without having to do a factory reset or doing anything to my router/network.
Let me know if this helped!
