GPRS drops out when USB is connected

[Guest TerryG]

Is there a clear explanation of the operational relationship between GPRS, WiFi, Bluetooth, and USB?

Seems if I am plugged into USB to charge my MDA, though Active Sync has enable USB unchecked in Connection Settings ('cause I sync with BT), GPRS drops to GSM (I believe it's GSM when the little tower and arrows are gone and there's just a square with a G).

Same thing happens if WiFi is up, as soon as I plug in USB the Wifi icon disappears in favor of the square with a G.

I have to say I haven't dug into fully understanding the My Work, Internet, T-Mobile GPRS, .... settings yet; that's kinda' what I'm doing here.

Why can't I have:

1. The unit charging over USB

2. GPRS active

3. WiFi active

4. Bluetooth active?

... or any combination thereof?

Are there settings I can set on the MDA in to accomplish this?

Why does plugging in USB stop the unit's ability to access the Internet to browse or email?

Also, are my expectations too high to think that these connections should stay up, assuming your location doesn't change? Seems the connections break and I have to stop and start the radio, or WiFi, a lot to get them connected again (arrows not moving).

Also, but not really also, what determines which network will get email? Browse? Can I set it up so that both use GPRS, unless WiFi is running, and if it is, use WiFi, and when it's turned off, revert to using GPRS?

I am using DJVW Optimizer that turned on 802.11g on my T-Mobile MDA (and did other stuff too?).

Thanks, er, I mean Thanks!

Terry.

Hi there, from my experiences, BT and WLAN are still active when charging via USB ... Also, the main reason (that I can gather) that GPRS is NOT enabled when charging via USB is purely due to the fact that it uses your computer's internet connection, rather than charging you to use GPRS. So, that way, when you sync with your computer, it will download your MMS messages (if you have it set to do so, which it is by default by my Carrier), you can jump into IE, or even chat on MSN -- all using your home internet connection ;)

Hope this was of some help.

Thanks. how, where, and when did I set up my PC's USB port to share its Internet connection? I have no recollection of that.

Is this true of Bluetooth too? I have to check this out. I guess if I can still browse and check mail while connected USB or BT, with wifi and phone turned off in Comm Mngr., then that'll confirm it.

Many thanks.

You didn't set it up ;) It simply uses it (well, I didn't set it up on mine... It just does! ;)) And yes, the WiFi/BT thing is confirmed :( I was able to locate my neighbour's WLAN while synced with my computer :) I can't verify BT, though.
