Data switching in G1

Hi. I've bought my first Android device, a HTC G1 Dream. I've gained root access, installed the last Cyanogen release (with Android 1.6), RA-1.2.3.
What I've noticed is a strange behavior, quite different from the one I had with my BlackBerry Bold.
When I'm home I enable wifi, to save some datas from my (limited) contract. It works and I've set not to disable wifi when in standby. It works. But as soon as I go out (and the wifi coverage finishes), it doesn't re-enable UMTS data until I awake it from the standby manually.
It's quite annoying...is there a way to change this kind of behavior?
Thank you very much!

Is it still connected to EDGE or GPRS? If this is the case it is a PowerSaving feature, if it's totally lost connection with the net then you have a problem I guess...

When I connect via Wifi, it disconnects from edge, gprs or umts. And doesn't reconnect when the wifi coverage ends (unless I "re-awake" the phone,pushing the menu button)

from what i read your saying thats while its sleeping its not connecting to your data services when your leaving wifi coverage, so my question is: do you not see the data icon when you wake up the phone but after waking it it comes on or are u assuming that its not on?

Yes, I cannot see the icon as soon as I wake up it. Then, in some seconds, it reconnects. More, I can see it's not just a "icon" issue because my K9-mail stops collecting my mailboxes when that situation happen.

App Blocking 3g Access

I currently have something on the phone not allowing 3g access. I can't seem to figure out what it is, but I believe I narrowed it down to an App. I did a wipe and clean rom install and 3g was working fine. I did a titanium backup restore of all apps with data and now 3g isn't working again. Anyone know of an easy way to pinpoint what is blocking my 3g? I tried ending all tasks in advanced task manager, but I'm guessing the phone would need a reboot to bring back 3g?

Have you check you settings-wireless & networks-mobile networks-use only 2g networks?

ya I tried using only 2g network, I even tried researching the network and it finds tmobile in the settings. I even went as far as getting a fresh sim card prior to wiping the phone. Somehow after an app/data restore from titanium back up, tmobile internet no longer works still. It's why I wiped in the first place.

1) Double check your APN settings in settings > networks > mobile networks
2) In dialer, dial *#*#4636#*#* > choose phone info > scroll down > verify that 'set preferred network type' reads WCDMA preferred.
3) Also in settings, make sure you didnt set 'use 2g only'. Same location as #2 above

Thanks for your help. I actually just did a nandrestore from an image I had that was a week old and internet came back, so it has to of been something I done within a weeks time. I just hope I don't end up hitting the app that stopped it, if I think it was one, because thats the only thing that makes sense to me.

I have your same problem could you be so kind as to attach the img you put so I try too? thanks

Then you will have his phone.

you mean....?

i Think i have a similar problem... I turn 3g on and after half an hour i cannot access the internet anymore... The sign in the notification area shows the "sent arrow" blinking but the receive arrow does nothing... I have apndroid to control my 3g usage... I unistalled it, did a reboot but again the problem persists... Do you have anything in mind???
I forgot to mention that the exact same thing happens with 2g network as well

When someone does a nandroid backup, it backs up all the data on the phone. All of it, if you restore it to your phone, you will be logged into google as him, you will have all his contacts, messages, settings etc. If one of you downloads something, it may download on both machines. The only way to fix it would be to wipe both of them.

i have the same problem. two days ago its working fine. i just turn on turn off the wifi and it just works again.

Can also try turning the airplane mode on/off. This problem occurs if you use APNdroid or similar, or toggle mobile connection on the Desire ROM.

tired of trying and try to wipe, reset, several rom, so I decided to send it to HTC in England ... and the problem is which has the bootloader unlock my ...

Wifi NOT work at all??

I use public wifi in my school. I registered it and it s connected every time i turn it on. I have a good speed(58Mbps), OPEN security and a IP address. I used an app to moniter the data useage and there is a small amount of data use when i keep the wifi connected.
ANYONE KNOWS WHY??
THANKS A LOT.

ok not sure I am following you.
in the title you say wifi is not working yet you say you have a IP and it is connected then you say that you see data passed. So what is not working?
When you have wifi on at school can you browse the web?
Were is the data that you see 3G or wifi?
Why do you think that wifi is not working?
are you getting errors?
guess I am saying we need more to go on here. Details man we need details.
If I had to guess
If the small amount of data that you see is in 3G then that may be the phone "signing out" of 3G
If the data is on wifi then it is the phone registering on the network.
but still need more details.

Okey, I should not say wifi is not working. It is connected for sure, but when i use the browser or the market or any app that requires internet connection it never works. It does not show web page, app store content or anything from the internet. Maybe it is my phone? this phone works in some other spot in my school,but no way to use wifi in my own dorm.

and also I turn off 3G when I have wifi, you know some widgets can help turning off 3G, so I can save some data. It is just the wifi data count that shows a data use.

I am pretty sure it is this phone s problem. I just got my ipod touch and I test the wifi on itouch. Touch works perfect. Why this good looking captivate has so many problems?
Sent from my SAMSUNG-SGH-I897 using XDA App

[Q] Okay, I did search the forum but...

...I don't know if the problems are the same and apply to me.
Okay, I rooted the phone and upgraded to cyanogenmod 6...everything worked great (had a few bumps down the road but fixed them and continued on the way). I got passed the g1 splash screen and into the google sign in screen. I sign in but it doesn't connect to servers. I have data and am connected to wifi.
Did I do something wrong? What can I do to pass this?
I searched every where before I decided to post so please if you think that this is a repeat of an older thread, I'm sorry, that was not my intention.
Please help me.

T-mobile...
this is what it says exactly "Can't establish a reliable data connection to the server".
Don't know if it helps.
Thanks

Sound like you do not have a reliable DATA connection. Do you see the EDGE, 3G, etc...?

I don't see the 3G sign but I do see the wifi connection sign, and I do have connection to it...maybe it's not that strong? I'm currently using a wifi spot and am not at home, but shouldn't the 3G just cover where ever I am sorta speak?

you should also activate:
Settings->Account & sync : both background data and auto-sync
try this! i had the same problem times ago

Concur with P4p3r1n0. Also, make sure that your APN setting is there and correctly filled out.

That should have done the trick, where you able to fix it??

[Q] 3g data hangs

Hi guys,
on my xt1068 (5.0.2 stock, no root, locked bootloader), 3g data always hangs when I'm travelling (e.g. Home -> Work). The only solution is to cycle the connection....
When I'm at home it works like a charm, even for an entire weekend
The mobile data icon remains "on", with full bars and H/3g symbol...but I cannot send or receive data.
Any ideas? As you understand this is really annoying. :silly:
Thanks.

I have the same problem but not all the time and I'm still on 4.4.4, I leave the house therefore disconnecting from WiFi sometimes 3G doesn't 'pickup' esp. if I turn off WiFi after it has moved out of range, like you it displays 3G or H but no data can be sent, the only way to fix it is rebooting the device.
Do you turn off WiFi manually after leaving the house? as mine only seems to do it if I do that.

Hmm, I always leave the WiFi on. I'm going back home atm and I just switched it off. Let's see if 3g stays active...(even if it would be the exact opposite behaviour than yours)
Thanks for the tip, I'll keep you posted.
