How to disconnect GPRS?

How do I disconnect a GPRS session if I want the phone to use a wifi signal instead? Is there any way of telling the phone to always use wifi in preference to GPRS if possible?
The shiny new phone has just arrived, so lots of questions!
TIA

Hmm well I'm not sure if this works on Rhodium, but on many HTCs keeping the 'hangup' button pressed for a few seconds will disconnect cellular data connection.
If not, go to "Comm Manager", this should also have a button to disconnect it.
If that doesn't work, there's always datadisconnect.exe in \Windows (though that would be a silly thing to do every time )
Anyways, if you have a Wi-Fi connection, all connections made after that point should go through Wi-Fi automatically. Existing connections will keep using cellular data, until they are de/re-connected, unless the program asking for the connection specifically requests to use the cellular connection.

No luck holding down the Hangup button - I tried holding it for 10 seconds and the GPRS session stayed open.
I'm concerned about the situations where I think I'm connected to wifi but there's been a DHCP problem or something, and the phone quietly goes and uses GPRS instead (so the wifi icon is shown at the top, but there's actually no network connectivity via wifi).
Does anyone have a good solution to this?

There is an app available called "NoData" that lets you switch GPRS/3G/HSPA off. But you have to switch it back on to use it again...

I just found an option to configure the Hangup button so that it turns off GPRS, so problem solved! (by default it locks the handset)

You need to do some "RegEdits" to obtain this.. go here...
HKEY_LOCAL_MACHINE\Comm\ConnMgr\Planner\Settings\
add a DWORD called "CacheTime" with value of "60"
then add "SuspendResume" as a string with "GPRS_bye_if_device_off"
obviously minus the ""'s

beware that tweak breaks simultaneous voice and data

I've never had any problems with it, when I have a 3g connection active I can make/receive phonecalls and keep the data connection live. I reguarly download files while on calls and they have finished by the time I hang up...?

What exactly does this tweak do?
I actually managed to configure the Hangup button to close the GPRS connection using the standard Button Settings menu, but I'm curious to know what your registry settings will do.

This will automatically disconnect the GPRS after xxx seconds (60 in the above) if GPRS is not used.

ARgghh! Damn internet connection!

Hi guys, I'm so pissed of!
My phone is online via wlan, but while I say check for updates it used my sim card to go online! This'll cost me aalot of money
How can I force my phone to go online ONLY if it's connected via wifi? Is there a way to disable the connection via the simcard?

Yes, there's a program called "NoData" which allows you to do just that.

Maybe you could change your Network Management settings.
Open "All settings", select the third tab (connections) and tap Connections. Select the second tab (advanced) and tap "Select Networks". There you can select how programs connect to the internet. Choose a profile that uses no modem and it should work.
The only program that refuses to stay disconnected while not on Wifi is the Youtube “program” when I accidentally start it again .
Hope it helps.

Thanks guys! I tried nodata and it works. I tried to select another profile but I thinkt that I f*cked that one up aswell Nodata is ok atm
Only downside I can't see if I am in my homezone or not :/

Data connection problem when coming back from Airplan mode...

I've stumbled on a strange issue.
If I switch the Desire to the Airplan mode when the Data connection is off (I use the appropriate HTC Data connection widget to do this), when I switch back to Airplan mode off, the phone is no more able to restore the data connection.
The only workaround found is to restart the phone.
Has anyone got the same experience?

Two questions.
1. When you say you switched off data connection, are you talking about syncing, wifi, mobile network, ... etc?
2. Why do you want to switch off data connection and turn on Airplane Mode? Doesn't Airplane Mode cater for shutting down all wireless?

1. I'm talking only about the "Data connection" option on "Wireless and networks" menu, that is switchable via a special HTC widget. Switching this option off, the phone is no more able to access to the GPRS provider. I often keep this option off to save battery life. I turn Data connection on, if I need to sync and access to Internet.
2. This is not the matter, just it happens. Eg. When I go to sleep, I turn the Airplane mode on, doesn't matter if the Data connection is on or off (it is possible that it is on) in order to avoid any disturbs (calls, sms, etc.).
I just wonder if this issue is a true bug of the phone:
1. Switch off Data connection
2. Switch on Airplane mode
3. Switch off Airlplane mode
4. Try to activate Data connection (for me it seems it's not possible without a reboot)

Had a similar problem which I wrote to HTC about: after the phone has been data connected via wifi and I leave the wifi network it often will not connect to data via mobile network (GPRS/3G), giving the message "connection failed" if I try to manually connect in the "mobile networks" section of the "wireless & networks" settings page.
It seems to have fixed itself now, and I think it's because I've since ticked the option to "enable always-on mobile data", which I had turned off to save battery. Give it a try.

Thanks yurikg, but on my phone the "enable always-on mobile data" option is checked, anche there is no mobile network connection problem coming back from a Wifi connection.
The problem I shown is probably caused coming back from Airplane mode.

The other possibility is Juicedefender which apparently is known to cause problems recovering a mobile data connection (recent update may have fixed this):

I've not juicedefender on my Desire...
I've in plan to do some other tests...

I have a problem with my Desire reconnecting to a mobile data connection too, but not when I come out of 'plane mode, its when I leave a Wifi covered area. It could be the same problem, triggered by anything that disables and then reactivates the data connection?
I have no solution yet, and I have contacted HTC support about it (still no reply). There is some discussion here:

I seem to be having this problem too when coming off WiFi connection, unfortunately restarting the phone has not righted the issue...

I'm also having this problem with the connections. Fine on the wifi at work and at home but not switching over to the mobile network. Apart from that the phone seems awesome! Soooooo much better and more fun than the HD2.

OK, my phone appears to have no network connection whatsoever in fact...

Have the same problem as well. Coming from Wifi and to mobile network only - I do not get any data coverage. This is for the Desire and I had the same problem with Legend.
I hope this will be worked out ASAP.

Well, my problems all sorted. Turns out I had to manually input the APN for internet, took me by surprise since no phone I've owned since 2006 has needed that...

Just had to put in the settings manually too. Seems there is an issue with some of them. Would put a link here but as i'm a newbie not allowed Just google vodafone apn settings for htc desire and hey presto

Same problem here, my Hero had it too. I found it did work when you switch to gsm only and back to 3g/gsm... Would love to hear good solutions.

Im also having the same problem.
If i try switching my connection from wifi to mobile data, my mobile data connection fails to work. A power cycle fixes the issue but if i try switching connections again, the problem returns.

Can I suggest to anyone still having problems getting their phone to switch to mobile data when leaving Wifi to view the following bug report on Google Code and to star it to help raise the priority with Google:

[Q] New ROM Data Connection keeps turning off/on ramdomly

I have an ATT Tilt2 with an unlimited data plan.
Since I installed the new ROM the data connection keeps turning off and on without warning. It is interfering with various programs that use that connection and I never know when it is going to happen.
For example: When I get up in the morning, most of the time, there is an error message on screen telling me that the system failed to dial out to make a connection.
When it is off and try to turn it on manual it doesn't work. I go to the "Wireless Manager" page and turn the "Data Connection" on. It acts like it is trying to activate then after a second or two it turns off while I am watching the switch. The only way then to turn it back on is power down the phone and restart.
I don't use WiFi very much and most of the time it is turned off. Normally, when everything is working okay the only items on are the: Phone and Data Connection.
Does anyone know how to fix this problem and keep the Data Connection "ON?"
Thank you,
Richard..

Here is the error message that pops up when the data connection fails:
Dialed:
Cannot connect for an unknown reason. To check your connection settings and change them if needed, tap Setting. If the problem contineues reset your mobile device accroding to the manufacture's documenteation and try again.
I have reset my device and this problem continues to occur. The only way to reset it is to restart the phone.

Sprint Samsung Tab 3 Wifi Issues

Hi. Not sure if anyone here can help, but I've been having serious wifi issues with my Sprint version Galaxy Tab 3 for almost a week now. The wifi signal shows that it's strong, but the network is "Turned off." I can connect back to the wifi network manually, but it just turns itself off again after another minute or two.
I deleted all the apps on it in recovery mode, and it did stay connected once everything was gone, but when going back into regular mode, the problem returned. So I factory reset the device, but the wifi "Turned off" nonsense continues.
This is not a rooted device. I've noticed that Sprint network crap comes up, but there's no way to access them outside of their popping up. One Sprint Connection app pops up but goes away almost immediately, and when I try to select it in the "open apps" list, it disappears. It also has been asking me to configure a hotspot. I select my home network and it connects for a little while, but again, just a minute or two.
Any ideas how to solve this problem? Thanks.
