Whats the diff between csd and gprs. Right now I created a new connection by doing start; settings; connections; connections; modify (internet settings). Under "My connection" I have it set for "cellular line (GPRS)". Under baud rate it is 19200 (why so slow?). Clicking next I have "wap.voicestream.com". This works but is really slow. Is this the correct way to use GPRS or is this CSD? If not, what is CSD? Is it better. Sorry for so many questions but I really dont know much about this. I have t-mobile in the US (southern california).
CSD (Circuit-Switched Data)
CSD is similar to your PC dialing up to a ISP / corperate modem pool for a data connection. For XDA or a cell phone in general, it consumes your air time. (If you make the CSD call during nights & weekends with T-Mobile, air time is free.) You get a 7Kbps avg narrow pipe - pulling an Internet page is very slow, but you can turn off the graphics on XDA to speed it up. GPRS is designed for data, giving you 40Kbps avg pipe, comparable to your PC dial-up speed but you have to pay T-Mobile $20/mo for unlimited data service. See thread

for setup. Hope this helps.
Pls help. It drive me nut.
I'm at home connect to (WI-FI) when i connect to internet the GPRS connection was active also. If i disconnect the GPRS the WI-FI still active but when i switch the web site page the GPRS re-connect back again.
How this happen??? only want use connection one of a time. If wifi available then GPRS inactive and otherway around if wifi inactive then GPRS active.
I have no proof of this, so it's just an assumption. I believe that the GPRS connection may be live but not actually in use. Both icons show up when I use WIFI too. I wouldn't pay too much attention to it. If you don't have a data package and want to avoid ever connection to GPRS or even temporarily block it, you can go under connections, connections, advanced, and set both to my work network. If you want to use it again, then set the second one to medianet or whatever your GPRS profile is named.
I configured my private wireless network, and the needed configuration for my cellular carrier web connection.
The issue is that whenever I am trying to surf to any webpage using my wireless LAN, my trinity always trying to connect to the cellular network, without using the available wireless connection. If I'm trying to cancel the conection process, it stopped but I can't surf anywhere.
Any ideas how to force the trinity to use the wireless network when available?
Thanks,
Amir.
In your connections configuration, create a new connection and do not add any entries to the Modem Section. Just configure the Proxy setting according to your ISP requirements. You have to change the connections configuration ach time you want a different connection to the internet. This you can do easily by creating different connctions for different situations.

It sounds as if your connection to the WLAN Router isn't being recognised.
1st thing to try is to go into the WLAn control panel, and in the Power tab, make sure the slider is fully to the left for max performance.
In the Network Cards CP, see if your router is listed, and whether Available or Unavailable.
Recheck the security settings- are you using WEP or WPA? Does your router have any Range Extender features- if so, turn them off.
Once you have a valid WLAN connection, the PPC will use that in preference to the GPRS, as long as you have WLAN conneced before opening PIE, and as long as there is no current GPRS activity when you open PIE (I find that if my Exchange Server is connecting via GPRS, then WLAN won't connect till the data session has completed)
For a quick way to force GPRS off, then on as needed, look for a great free app called Bandswitch. This allows you to force the P3600 to use GSM or 3G if needed to conserve power, and also to quickly enable/disable the various GPRS connections.
Hi All,
New to my fantastic HD Touch so apologise if this is an obvious question..
If I have wifi enabled and data connection enabled, if i go onto the internet or, say, Youtube for aguments sake, will it use the Wifi connection as a priority over the data connection?
I ask because i want to keep my bills down without having to manually keep turning the data connection off (it connects every 5 mins to check for email)
Thanks
Loving this forum by the way!!
Depends on how the connection is set up. You can check your config by going to settings->connections->connections->advanced->select networks
There is then a drop down under the heading "Programs that automatically connect to the internet should connect using:". When I bought mine this was set to "Contract Internet" which basically means my vodafone data connection. I managed to run up a bill of over £50 before I spotted this (this was before I moved to a decent data package).
I changed this setting to "My Work Network" and it then used the wifi in preference to the cell connection. However, I think (although haven't scientifically tested) that if a program gets a cell connection before the wifi is activated then it may not automatically switch over if wifi is subsequently enabled.
BTW I tested all this using a $10 app called GPRS Traffic Monitor (which can monitor HSDPA as well as GPRS) to see if the traffic figures rose while browsing the net with wifi on and off. After changing my settings the data usage figures only went up if wifi was off.
Everyone,
Apologies, and I know this is a stupid question, but when at home with my htc tound pro, with WiFi on, and connected, why do I need the phone on too for the WiFi to work,...?
Also, when both are on and working, which system is used, i.e., the SIM card connection or the WiFi connection,...?
WiFi I pay a flat monthly rate for unlimited data, with the SIM card I am on a fixed amount of data transfer per month,...
Thanks for listening,

Well..
You may be using an application that is not Wifi aware. So, it demands a GPRS/EDGE/3G connection. So - in effect - it's not actually using the Wifi connection.
If you can use the application with Wifi on, and phone off - it's Wifi aware. (Meaning it can utilize Wifi).
If you can't use the application without the phone being on - it's not Wifi aware or has not been configured to use the Wifi.
What application are you having issues with?
thanks for getting back to me,... WM Professional 6.1 and the Internet Explorer program when going on to the web,... i'm just wondering which systems does the phone use when both are functioning,... am i using the gprs from my SIM card or am I using the wi-fi in my home,...? and why do i need the phone turned on to use the wi-fi in my home,...?
thanks again,...

you can see if it's using gprs on the icon for signal str if it's showing animations
it's using gprs
otherwise it's using wifi
if you set
settings-connections-connection-advanced-select network to my homenetwork
it dont use gprs
did you set the gprs settings to your gsm provider?
i would prefer wifi over gprs/3g anyday unless if your home internet is extremely slow ( <300kbps). the battery life would be almost equal so why not a faster connection?

I'd like to understand how WM decides which network to use when it has a choice e.g. HSDPA and WiFi. I've looked at the settings mentioned above and I currently have Internet using Contract Internet (HSDPA) and Work using WiFi as the WiFi networks I connect to are firewalled and privately addressed.
What settings should I have to ensure that when I have the choice of WiFi and HSDPA (at home) I use WiFi, and when out and about I use HSDPA?
Everytime an application wants to connect to the net:
- If wifi is connected and GSM isn't, it uses Wifi
- If wifi isn't connected, it tries connecting to GSM and will use that.
- If both are connected - we don't really know what happens.
When you're at home, check that GSM is not connected (no little E, G, 3G or H on the signal bar icon, disconnect it if connected), turn on wifi, wait until the arrows have stopped moving on the Wifi icons, and now you can launch the program that wants to connect to the net, and it will use wifi.
If at this point you get a popup about the phone connecting to GSM data again, then there's a connectivity problem on your Wifi and the device can't reach the net through it.
You might want to install Modaco Nodata, it allows you do disable automatic connection to GSM so that you can be sure it doesn't connect when you don't want it to.
mine never use gprs when it have wifi
I have a Touch HD and I can make things work fine by manually turning off the data connection then turning on WiFi in the comm manager when I'm at home or vice versa when I'm out and about.
I would have thought win mobile 6.1 would have been a mature enough OS to allow this to be configured automatically. This and Opera are my only outstanding issues with the HD.
Strange. I can easily shut my phone off, enable wifi & browse fine.
