doesn't switch back on properly on Nexus One

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Switch data connection off for some time (e.g. 30min)
2. Switch back on

What is the expected output? What do you see instead?
Data connection via GPRS / 3G should work again. - EDGE (in my case, I've
disabled 3G generally) is displayed as online in the status bar. However,
no data transfer is possible.

What version of the product are you using? On what operating system?
Nexus One / Firmware v.2.1-update1
APNDroid: Latest version from Android Market

Please provide any additional information below.
Manually switching between valid / invalid APN in the settings menu works fine.

I have exactly the same problem - there is no data connection after switching 
on.
Data connection works only after soft reboot.

Phone: Nexus One with the oficial firmware 2.1-update1
APNDroid: Latest version from the Android Market

Same here in Italy with Nexus One and TIM Ibox connection. I have to reboot 
after 
Switch back ON to make the connection REALLY on.
All works fine manually switching between correct/uncorrect APN in the settings 
menu 
and without reboot the Nexus.
PS: the SAME problem happens with "Toggle Data" widget.

Great!!! This in the very ONLY issue I've noticed with my Nexus One!!!

It would be great. 
By the way "Quick settings" doesn't work either.

It seems it is Android problem rather APNDroid problem.

After long trying of an access point OS gives up and marks it as "bad". I 
suppose so.
Or some kind of pppd issue.

r14 does not work also.

"E" appears, but only downlink (down arrow) blinks. Uplink (up arrow) never 
shows
until reboot.

I will have Nexus One soon (thanks Google :-) so I will be able to dive deeper 
into 
this.

You know, HTC Hero (HTC Sense) also have built-in possibility to disable 
internet
access. Without changing APN.
And it also does not reconnect. It seems it's common problem for Android 
devices, it
does not depend on Nexus or something like that.

And if APN is incorrent, does device try to reconnect to wrong APN constantly? 
Tries,
tries, tries?

Actually no Android device reconnects after turning APNDroid off, then working
through wifi, and then switching back. I had three.

First you need to turn on APNDroid, then you may turn off Wi-Fi. Then it will 
use
GPRS, otherwise won't.

Reposting from priv. account, with additional info:
> I tried r16 for several days, and the success ration is way better than 
before. 
> It still happens that the connection restore is unsuccesfull, though :(

I just tried the following sequence:
1) With APN disabled by APNdroid, browse web over Wi-Fi.
2) Turn down Wi-Fi, try to browse web, get "unreachable" error.
3) Turn APN on using APNdroid, 3G instantly turns on and works correctly.

It sometimes fails to start, though. I have not been able to isolate any 
sequence of events that would make it 
work or not work.

Same here (on my nexus one). Can't re-connect to internet after turning off 
wifi even
3G icon appears in taskbar.

I've heard that other applications like Toggle Data do not rename APNs, instead 
they 
change the APN type from default or "mms" to "-" and then restore it back. It 
seems to 
work better than APN renaming and may help to solve this problem.

Same problem here with a Nexus One and Simyo (Spanish carrier). The wifi or 
airplane
trick doesn't work for me either...

this is actually DNS and most probably pppd's problem. In described conditions 
It 
doesn't update DNS'es to GPRS/3G ones. However, trick with probing access when 
WiFi and 
APN toggled OFF and only after that toggling APN on works for me (at least once 
:))

@cristiandan1970 I left my Nexus One with internet OFF for 4 hours, and then it 
just came back immediately. I 
am not saying it doesn't happen (for sure it does, we have many reports), I am 
just saying that I can't reproduce 
it, so fixing might be really complicated.

@lokoyaw yes please, send the logs, definitely would help!

No this note just tell that if you remove APNdroid in the off state you'll have 
to
restore apn entries manually. This thing does not lost connection bug

I love apndroid, but it doesn't properly turn back on the data access for me on 
my
Nexus One. As a workaround, instead of using apndroid, I ended up creating 
another
fake APN and if I want to turn off data, I just switch to it. Turning data back 
on by
switching back to the proper APN seems to work every time for me. Is there a way
apndroid could mimic this behavior?

I wrote a simple app that calls the APN settings configuration dialog on my 
device to
make switching APNs easier. If anyone is struggling with this bug as well, and 
wants
to use my hack, here's a link to what I wrote:

@jmdsdf On my Nexus One creating fake APN doesn't work, phone always selects 
the correct one :-( Problem 
with turning back the data connection is a very popular bug in Android itself - 
look at 
https://code.google.com/p/android/issues/detail?id=2207

@martin.adamek What you are saying is strange. Are you sure you have selected 
the
fake APN? (indicated with a green dot on the right beside the name) It works
perfectly on mine. My Nexus One does not automatically select the working APN 
when I
have the non-working APN selected.

Here are two screen shots I took with DDMS of what I see:

I do exactly the same thing with fake APN :) 
To force Nexus One to not to switch to the working APN you have to set fake 
APN's type 
as "default".

Any news? Maybe is fixed in Android 2.2?

Original comment by [email protected] on 23 May 2010 at 7:23

[GoogleCodeExporter]

Android 2.2 itself contains data on/off switch (have a look at the attached 
screenshot). I didn't have enough 
time, but I didn't see this reconnect problem so far (doesn't mean it's not 
there). Other than that, we have also 
new way of turning data on/off without modifiing APNs that could be ready to 
test in few days. With this method 
and short testing I didn't see this problem either (but personnally I think it 
is there, because Android bug 2207 is 
not fixed yet)

That's cool. I didn't see a screen shot, but on Froyo I see it under Menu | 
Settings | 
Wireless & Networks | Mobile Networks | Data enabled. By the way, the app & 
idea I 
posted still works well under Android 2.2 on my Nexus One.

Original comment by [email protected] on 26 May 2010 at 12:33

[GoogleCodeExporter]

For anyone using the Nexus One w/2.2, who wants an app to toggle that quickly, 
here is 
a quick application to get directly to that setting (i.e. Menu | Settings | 
Wireless & Networks | Mobile Networks): 
http://jmdsdf.yi.org/share/DataSettings.apk

However, I don't like the idea of using that solution and like the idea of just 
toggling between a functional and a non-functional APN. I have a untested 
feeling that 
it will disable MMS as well.

Original comment by [email protected] on 26 May 2010 at 1:21

[GoogleCodeExporter]

Use nexus one with froyo (2.2). As someone expected, turning off "data enabled" 
will also turn off mms. 
Switching to a fake apn seems to toggle data connection correct every time 
though. Created a apn with 
name and apn named fake, and apn type set to default. Switching between the 
fake and the normal 
seems to work, without having to worry about wifi on or off. Mms received fine 
also when using fake 
apn. Have problems sending mms though, but that is an issue i've always had, 
and is probably 
something else.

There is a problem with only changing to a fake apn. When phone cannot get 
connection on the fake 
apn, it switches back to the normal. A solution could be to change the apn like 
apndroid does, and then 
use the switch to a fake apn as a trigger to get it working with new settings

I have written a switcher with 2 solution,i.e. with suffix, or with fake apn. 
The latter may be suitable for the n1. It is named HiAPN on Android Market. 
Hopes it may help us.

What seems working on my GalaxyS (Android 2.1-update1):

 - Create a "fake" APN withthis settings:  name="Fake", APN="fake", APN Type="internet"
 - Download AnyCut from the market
 - With AnyCut, create a shortcut to the APNs activity

Now you can enable/disable data connection by clicking on the shortcut and 
selecting either the fake or the real apn

I'm using APNDroid from Tasker and I am observing the same behavior on my HTC 
Desire running the 2.2 OTA update: the network does not come back on.
Would it be possible to use the "fake apn" approach via Tasker?

I've just installed an OTA 2.2 update on my HTC Desire too and the "Keep MMS

click download on the MMS message and then disable afterwards.

I have experienced this issue ever since I purchased my Nexus One a bit over a 
month ago.  I am on the Vodafone Australia network.

I have tried everything, but nothing will fix this problem.  The only way to 
reestablish the 3G connection is to go into airplane mode and back.  Please 
work on a solution, because I need to reset my internet several times a day.

I noticed that after activation, as apndroid select the 2nd APN profile and it 
feels so that 3G does not work. This bug also happens with several software 
packages of the same type as LG Optimus 2X.
