Data Problem since Mango

Hi Guys,
My phone has developed a pretty cripling problem since updating to Mango. I waited for the official update from my carrier without any forced tricks.
Basically my data connection is randomly dropping out. My phone will still display G/E/3G/H or whatever but there is no network connectivity. Nothing works and if i try a web page i just get connection/dns errors.
The only way to solve this is a soft-reset. Even flight mode on-off doesn't always seem to work.
I thought it was a bug on my network since Orange and T-Mobile share and that it may have had a problem switching between but i've manually selected my home network (Orange) and it's still happening.
So basically i'm now in a position where i have to manually check my data connection is actually working and if not, soft reset my phone. I can't be doing this, it's ridiculous having to re-set my phone numerous times a day!
Like i say this problem has only arrisen since Mango. I've read on the net a few others with this issue but no fix.
Are any of you guys experiencing something similar? Or know what I could try?
Thanks :/

I had that issue with WiFi for a couple of days after updating but it fixed itself. You might want to ask Orange for a replacement device if it stays like that.

I'm experiencing the exact same issue with my HD7 since a couple of days now. But I assume it's a hardware failure. My device is causing all different kinds of trouble like rebooting randomly several times a day, refusing to launch apps and so on. I'm going to send it in for repair.

It's odd i didn't notice it for a week after updating but then when i was out and about it dropped. Then every day since it's done the same thing.
So frustrating, it doesn't appear to be a localised network issue as it happened when i travelled around 100 miles away too!
Might give orange a call then and see what they say. Just seems a bit of a co0incidence that it's only happened after the Mango update.

Been on the phone to orange - They've sent me some network settings message, tbh i can't see it doing anything but they said if it carries on they'll just replace the handset.
Bit annoying really since other than this it's flawless.

I have the same problem, just restored back to pre-mango. no point being on Mango if i can't consume any data.
Spoke to Orange couple of days ago and "they said not our problem, call Samsung".
a joke.

Has restoring back fixed the data problem?
My sister also has an Omnia 7 on Orange and she has the same problem. So that's at least 3 cases Orange have been made aware of, I can only assume there are more.
I don't see any point retunring my phone as i assume when i update the replacement to Mango the same problem will arise.
Also do you have insurance with Orange? I was offered a replacement as i have the Orange care thing.

For reference,
I started a thread on the MS Answers site and a few others on Orange UK are
having the same problem.

If anyone here is suffering could they add their details to the list and mark it as "im having this problem too" to bring it to the attention of MS please?
Thanks!

I have a simfree omnia7 with an o2 UK SIM in it and I also have data connection problems since the mango update. It must be the phone coz it works fine on my desire HD with the same sim in it. Mite be time to get myself a titan instead me thinks.

I just resolved this problem for my HTC Trophy!!!!
The cause seems to be that the APN settings where erased/blanked after the update to Mango.
I have a Vodafone branded HTC Trophy and my provider is T-mobile. After I supplied the APN settings from T-mobile, my data connection keeps on working!
Try it, maybe this helps!
APN settings can be edited through "Settings" - "Mobile Network (or Cellular)" - "edit apn" (scroll down!)

I have a similar problem on the Omnia7 with T-Mobile.
Sometimes my connection just drops, completely, no bars, no internet nothing. It'll come back after a few minutes though. I also have seen some similar problems to you with internet, displaying 3G+ but not actually loading anything.
I also seem to roam a lot now on T-Mobile Orange, even at home and when roaming I can't use the net at all.
Having said all this, I didn't force Mango but I was on the Developer Beta which (I think) means it just automatically upgraded to a generic Mango rom? I'm pretty sure T-Mobile have been slow with their updates, I've had mango since the first week release.

[Q] T-989 - No data network. Mobile Network State: Disconnected

Hi there. I own an unlocked, rooted t 989 Samsung Galaxy SII which I bought in the US. I recently moved to the Netherlands, and got a new simcard with Vodafone. The problem: I can't get my data to work.
I have tried (almost) everything, so prepare for a read. Here's the list:
- Sim card is fine, I tried it in a old phone and 3G pops up instantly
- Rebooted, pulled battery, turned mobile connections on/off, handpicked network, etc, etc, all the basics.
- Got the APN settings from Vodafone. Tried them manually, resetted them, automatically, turned it on, turned it off.
- Going online through Wifi works.
- Under settings-Status it reads under Mobile Network State: Disconnected. But I know that the phone detects the network correctly. It can distinguish between UMTS and GPRS here.
- So there seems to be no trouble with the phone being incompatible with the network. I read online that other people had NO trouble using their T989 in Europe.
- I tried inserting my old American pre paid T mobile sim card and turn roaming on. No luck.
- A lot of other people with the same problem tried to link it to Easy Battery Saver. I tried updating, uninstalling and going into its settings to find out what it could be, but nothing.
The last thing I can still try is to factory reset, unroot and try to get the phone to its most original state and see what it does. But before I triple wipe all my contacts, pictures, apps, etc, I want to make sure I did absolutely everything to try and fix this beforehand. Being a noob here, I can't post any links but I trust you I tried.
The people at Vodafone are of no help whatsoever. I hope you geniuses could help me any further.
[Edit] And sorry for posting this in General Chat. If a mod could move my question to Q&A I'd be most thankful..!

I am having the exact same damn problem! it started with being unable to send a simple text message yet having data. now it says it is searching forever

Try flashing a different radio/modem then an american one?

@decko5 Nice to see I'm not the only one, but that doesn't help us yet .
@doug36 Besides the fact that I'm running a stock ROM that should be compatible with no issues, I'm not sure how I'd do that. I can flash a separate part of the kernel? That sounds like a very tricky thing to do.

It's actually pretty easy. You can flash most radios via ClockworkMod Recovery. I couldn't find any threads with a list of Galaxy S-II radios here on XDA, but I found one over at RootzWiki for you. http://rootzwiki.com/topic/2725-radio-samsung-galaxy-s-ii-radios-updatezip-updated-20-aug-2011/
Just find the corresponding one to your geographical location and carrier (Google is your friend) and follow the steps.
Good luck and hope it helps!
(p.s. you should definitely look to see which radio you currently have so that you can download a backup of it before you go flashing radios.)

Thanks for that very helpful post! I've raped and butchered Google, but I'm still having trouble finding out which modem I should download. There seem to be so many and the post on RootzWiki gives no guidance to which is which. Any wisdom on this? I'm in the Netherlands, so Western Europe, on a Vodafone network.
By the way. I fully wiped my phone and installed Team Kang's Juggernaut 5.. No luck, same problem. What I found really, really weird is that it was instantly in Dutch. (Which is ok, I speak Dutch) But I don't remember ever selecting a language. How does it know? Besides, I'd rather have it in English .
What I did find out is that I'm still using a old firmware, UVKID, instead of UVKL1. So I'm restoring back to my previous ROM and trying to update. I'll see what happens. If that doesn't work, I'm going to restore my phone to stockest of the unrooted stocks and try and update.
If that doesn't work, I'll have no option but to send the phone to T-mobile.
I'll try the modem update as soon as I understand what I'm doing . But it does sound promising. Thank you so much for your help, it's greatly appreciated!

Hi guys,
I've updated my firmware to UVKL1, still no luck. Anybody who can tell me which radio I should try on this Vodafone network in the Netherlands?

I am from India and had faced this similer issue with many of my android phones specially with captivate and infuse.......Here what i always did to connect data network.
Just uncheck the use packet data network box in mobile network settings and try to move out from that area (say u are in ur office and going back home) and check the data in settings.
This thing has worked for me always, I don't knw if its related to the OS or to the network provider but this has helped.
Have u tried any other network sim card on ur phone ?

An update for other people that might be looking for a solution in the future. It turns out to be a clear Vodafone problem. I tried a different simcard from a different network (both T-mobile Netherlands and KPN), and they instantly worked without any trouble.
I went back to a different Vodafone store in Amsterdam, and they were much more helpful than the first one. The sales guy told me he had seen the same problem with AT&T iPhones on the Vodafone network.
I called Vodafone, and they have been very nice to me. But they haven't found a solution yet and are looking into it. They see me registering to the network, granting me access, but still my data doesn't work. They've also told me that they will let me cancel my contract for no cost if they don't find a solution.
So problem remains unsolved, but at least there's some light at the end of the tunnel. I was close to buying a new 500 dollar phone... Americans going to Europe: Beware with getting a Vodafone simcard. Sorry to the Vodafone guys, but as for now, that's the status.

So to give closure to this issue (I always hate it when people fix their problem without telling the interwebs..)
IT WORKS!
After an initial terrible experience at the Vodafone counter, the headquarter tech guys have really been great to me. So it is indeed a Vodafone problem. American phones always give them a headache. They don't know what causes the problem exactly, but they do have a fix. It turns out that when logging on to the data network, American phones (AT&T iPhones, my T989 SGsII, and some other Android devices) sent some gibberish along that make the Vodafone server go cuckoo.
The solution was, miraculously, to sign me up (for free!) to the WiFi hotspot service that Vodafone provides, and then logging on to a different APN, being: office.vodafone.nl in my case.
Hope this helps anyone who's having similar issues.

ok the issue here is that some of the t989 are vodafone and some are USA network , now the other solution is that you flash with command prompt which there is a link to that tool im going to upload from the link i got it from . its also a clockrecoverymod , but this 1 asks you for deleting data user on the device and also resets the network includes USA/overseas though if your not customed roms
or any hacked roms , after flashing this device your basically removing any unwanted apps and cache that are hidden during network searching will be fixed bugs , put the simcard in slot but make sure that is a 3G/4G accounts, than its going to reboot the device automatically , it should be searching for service and also will be a circle with a slash on it where the service bar usually is , just wait about 1/2 hour to an hour maximum time let it do its thing , ok whats happening now to the phone is that is thinking with android network with usa and overseas market apps comparing both carriers network also gets the proper address for the custom rom or original kernel, froyo either 1 will get the correct network address and / VPN / and also will be adding both T-mobile/AT&T choose T-mobile dont go for AT&T cause it will research network configuration plus the phone its not unlocked for both its just a network passby to get correct WPN/VPN/clockworkrecoverymod .

Where is an fix?

Data Connectivity Issue

Has anybody else had this issue where your data connectivity is lost randomly. I have the 4G/LTE indicator on and still cant connect. The are quite a few discussions on the net with weird suggestions on how to fix it... but anybody have any fixes?

mine seems to have an issue 1 in 10 times or so, only when connected to WiFi. I added the apn steps found in the Nokia forums. Seems to be ok, but I have to let it run for awhile.

I read these issues are the result of a defective batch of Lumia 900's and regardless of the fact that some of you have have workarounds this problem may re-occur again and again. I'd recommend a handset swap if possible.
http://www.phonearena.com/news/Some-...issues_id28888

Since adding the apn in, I've not had a single problem. But, grain of salt, I didn't have that big of an issue in the first place, and, its only been 7 hours ir so.
The apn thing was required for while on T-Mobile windows phone devices on launch of seven. Nodo fixed it and it was no longer required..
But before running of and branding all issues the result of some mexican imei foul up, read some of the other thoughts. To me its more plausible to think of the issue as a provisioning scenario, or apn, to think some banditos are to blame. We can blame them little buggets later, and why waste a good excuse so early.

[Q] suddenly can't see any mobile networks - Baseband "unknown"

SYMPTOM: can't see any mobile networks
BACKGROUND: I've been using htc one x for a month now. Initially on three, but their signal was unusable at home, so sim-unlocked and switched a couple of weeks ago to giffgaff ( a virtual network on top of the UK o2 network).
All has been fine, until today. I sent a few texts & calls in the morning, and mobile data was working. Since then, I can't see any mobile network.
wifi is fine.
Search Networks pops up "Error while searching for networks" and finds none.
No software changes of any sort since last successful call. No changes at all today, at least until I tried to diagnose the problem.
Running stock rom, with the WW update of a couple of weeks ago (1.28.771.9.CL56522 release-keys) -- neither S-OFF nor unlocked bootloader.
Nothing obvious to me in the normal or radio logcat logs.
The only thing I did after the last successful call was to run sensorly to try and map a trip. I've used this before without any problems. It got no connection but I thought nothing of that. I've since uninstalled it just in case it could somehow be interfering with the radio.
THINGS I'VE TRIED:
No, the airplane mode isn't on, and mobile is. I've toggled airplane from settings and power switch, many times
recreated the APN
checked other phones - yes there are a number of networks visible
tried the original o2 sim - same problem
safe mode
cold boot
reboot, reboot, reboot
obviously I haven't pulled the battery...
turned off wifi, in case it was somehow interfering
HTC diagnostic tool
factory reset
confirmed imei is not blocked
Any ideas? Bearing in mind that I'm looking for something which can happen spontaneously.
Interestingly, while writing this I've just noticed that Baseband version shows as Unknown. That worries me - is it possible that my radio partition has spontaneously corrupted itself?
I did speak to 02 support - they said to take it into a shop for warranty repair. I don't want to try a custom ROM just yet -- not when I might have to use the warranty. But is there any way to force it to reinstall the stock rom (preferably not involving windows)?

I have the same problem as well and flashing custom roms did not solve it for me. But for me even the IMEI number is shown as UNKNOWN...I haven't done anything special to get this issue, one day when I woke up the phone could not connect to any network.
I have tried a lot of different methods but with no success. I don't think we can do anything about the baseband without S-OFF.

If a hard reset fails, then it's time to think about returning the unit. Either get a refund or get it replaced.

This may be irrelevant; but I've had this happen to me on my GNexus. I solved it by going back to stock and it just fixed itself overnight.....

my HTC One X did the same after about 2 weeks. Gave it back to supplier, waiting my replacement.
Even tested with a different SIM card, did a hard reset. Problem stayed the same.

Im curious did any of you find a resolution to this? it happened to me a while ago but yet to fing a solution. HTC refuse to fix under warranty because it is unlocked.. i am currently waiting for the next official update to see if that fixes anything but the way things are looking that could be a while..

It sounds like a fault, probably the radio chip has just stopped working, no software is going to repair that. If it was a software problem, there would be hundreds or thousands of people all having the same issue.

[Q] How to connect to hidden WiFi?

Hello xda community!
I have a strange and serious problem: I can't connect to hidden WiFi's.
I'm with a LG G3 D855 10H (no newer versions available).
At work we use a hidden WiFi without password but with Juniper VPN.
When I type in the network name and save it, it tries one time to connect, then my LG G3 shows "not in range". After a few seconds, the WiFi is on the top again with a very good signal.
When I try to connect again, it shows "not in range" again and so on.
I tried it at home and created a hidden network and it was reproducible.
Anyone else has problem with this?
Many thanks in advance for your help!
Best regards,
Jake

Now that is what you call a 'special' post!
Would you care to explain how it was resolved for the people that have the problem.

My problem still exists, but isn't urgent anymore.
I found out, Android itself have problems (or restrictions?) to hidden WiFi networks.
I also found an app names HiddenSSID Enabler, but it seems it didn't work for me (or G3?).
If someone has a solution it still would be very helpful fo rme and the rest of the community.

I have logs posted in my first post, WIFI DESTROYED TWICE or there abouts.
I've had to resort to DATA and its killing me haha i think i am getting close to fixing it, well i think i may be closer than you two and can one of you kindly take the lead as im reinstalling windows and i haven't gamed in 6 days :|
/system/etc/wifi/WCNSS_qcomcfg.ini
then the problem is complex but i am sure it is something to do with gEnableApProt=1
Offshoot fix, reinstall using googled imei number that doesn't have a flag or some how fix the flag <READ A FEW DAYS BACK>
I think actually the program that stuffed me was Airmon by maxters. It asked me if i was pro and of course, i said yes. Who would simply click no? I know a ninj wouldn't click no. I think there is a manual reinstall to link to it again i find the modem in its own partition having a chill, most likely trojan/backdoor and pwning everything around me.. I had three encrypted vpn backdoors and escalated accounts on my computer I paid the 5$ for the binarys, i think i paid 5$ for the back doors.
Not to sell Airmon out though.. Rooting our phones and accessing countless forums and websites really does leave us rather "xposed" some other cuplrits may be dsploit, ROM manager, linux Deploy/kali, Pamn IP scanner, system app remover pro, busybox pro's (Stephen/JRummy) or CMinstall/accessing the forums and trying to install cynagenmod / twrp recovery. I'm probably going to go with..... Airmon/Linuxdeploy or uninstalltool. But may have just been my IP logged and i hit a booby trap script along the way.
You guys done anything of the sort?
/Thread killller

Neither I understand what you are talking about, nor am I (as not native english speaker) good at "sentence guessing".
I have a rooted phone - of course.
But I'm pretty sure my WiFi is not destroyed...
