[Q] DATA connectivity problem with ARC

hi people
i'm noticing a problem with my data/edge/3g connection.
it simply stops working at times .. it just shows data being sent but no data received and my internet doesnt work.
This becomes fine after a reboot but again has a problem after a few hours
Is anyone else facing this problem too with Data connectivity ?

Yes, same problem with my german arc.

I am not facing any problem with data connectivity

same problems here, I found that stopping the WIFI and re enabling it is enough to get it back on track but its still a serious issue.
I don't like finding out I am missing e-mails an hour too late.

I only found it happens when I switch from 2G to 3G with data on.
So my work around is to turn data off first before switching between 2G <-> 3G. After that, turn back the data on.

This only happens to me on WIFI, on 3g everything is fine.
I am thinking about flashing the UK build to see if it helps.

I used to have the same problem with my x10. Data just stopped working randomly. I used to have a widget to turn 3g on/off and when the data stopped working, so did the widget. Was strange, and only a reboot solved it.

I have wifi problems,it sleeps after a while,no sleep is selectet.

same here. wifi works fine. til awhile later (evactly how long i didn't notice. will keep track)
After which no matter how i turn off & on wifi, forget the network & re-enter p/w. even off & on my phone. wifi status "connecting.... disconnected....connecting.... disconnected." will drains off a lot of battery if go unnotice.
i found a cumbersome work around... off the arc wifi & reboot modem/router. then can "obtaining ip address". but thing is, all other devices works fine.
so is it arc's fault? since all others can connect to wifi except arc
or
router's fault? i wasn't doing / changing setting on the arc. just reboot router. but wouldn't it be silly to do this everytime i use wifi on the arc?

so still no fix? sometimes it happens to me a few times during an hour...

Guys maybe this will help you out..
Go to wifi settings, press menu button->select advanced->under wifi sleep policy, set as never sleep
If not set the wifi shuts down to save battery.
And wifi is given more priority over 3g or 2g connectivity, so if you have wifi on you may not have proper connectivity to 2g or 3g

Turn on/off airplane mode, if you can't get a data connection. In a german forum some guys discussed about issues with multi-sim-cards, but I guess it is software related.

i changed my number and sim a couple of days back. with the same provider. my arc after being out of signal cant reconnect to the data network. the phone calls work fine. but the data is giving me problems. im still confused as to why this is happening. whenever i activate and deactivate the airplane mode, data connection comes back alive. could it be a problem with my sim or the phone radio?
edit: oh and i also reflashed my phone via sony ericsson update service, the problems still there.

Same problem here. This is really frustrating.

I dialed *#*#4636#*#* then phone info and pressed menu. Then I selected enable data connection (was disabled previously). The data didnt enable then. I went to settings>mobile network and enabled data from there too. Ever since, no disconnections. I dont know if this procedure or the fact that I tried to seat my sim properly worked, but u may try either. Let me know if this works....
Edit2: the above doesnt work.

I inserted my old fat sim and recreated the situation, the data automatically reconnected. The newer sim that's a microsim is causing the problem.

No 3G signal after getting off Wifi

Just curious if this happened to anyone or is it just me: most of the time I'm connected to wifi to save battery (home, school, etc) and when I'm out of range it should automatically connect me to the 3g network but it's not. I check settings and 3g is still enabled. Anyone know why?

I am also experiencing this. This happens to me when I am connected to WiFi with bad or no signal but then when I turn off WiFi and go to a good signal area it still registers no signal until I restart my phone then all is fine. Definitely a major bug.

ive had 2 of these phones, ive never had an issue with this. eh. maybe im lucky

Any solution to this?
Ever since I purchased this phone, I hardly get 3g signal. Will a hard reset fix this problem? I have to go by 4g or wi-fi on this phone for data.

having wifi on will actually kill your battery more because you have another radio running, thats why they give you the option to turn it off. (to save battery)
hmm thats odd though mine turns back on just fine
try a hard reset.
its deff a software issue

Wrong, having wifi on saves power because than your phone doesn't have to ping and search for cell towers

+1. Wifi Is definitelya battery saver. I leave wifi on all night at home. I get great battery life. I also never have the problem with 3g either. It always comes back even if I lose wifi signal.
The Evo3D Killer!!!

I noticed this in mine, so I went to Settings->Wireless and Network-> Mobile Network Data and then unchecked 3G and re-checked it and it hasn't had the problem since. Try it and report back.

a lot of users are having this issue along with low speed results on 3g, I read on another forum that Samsung/Sprint are working on it but I'd take that with a grain of salt. I fixed the radio wake up issue on my phone by doing factory reset and then going through the hands free activation again. Haven't had it since.

i'm having this issue too. Turning off wifi, or every time I go in an elevator and loose my 3g signal.
The strange thing though is I had this same problem with my OG Epic for the last two weeks I had it. I flashed back to the current Sprint rom and still had the problem. It was actually the reason I bought the Epic Touch on day 1.

I too am having 3G connection problems
My work is located a mile North of the 101 and Scottsdale and I can't get signal in my building, even if I walk to the big windows.
Of course Phoenix has no 4g so Im S.O.L.

GSM full bars greyed out with no connection

Hey guys I've got the GSM version and every now and then my signal bars turn grey, this is with full signal even showing 3g buts its grey and won't call out or load data. I'm not a twit and understand that phones loose signal its just strange it comes back randomly also. Very annoying.
I'm on 4.0.1 Google build anyone else get this issue?

grey full bars
i dont have a technical response to this question other than i only notice this during times of transition between either booting up the phone or switching to wifi on or off equally.
The phone usually checks to sync when it has been on standby and you then hit the power button. If you theoretically switch between wifi and 3g/4g during this time it would force a transition which could yield a situation as you describe.

This happens to me too sometimes. What network do you have?

You have to find out the true reason why your connection is being interrupted. The bars going grey instead of blue is just reflecting the fact that your connection isn't persistent and you don't have a full sync with Google.

Blue bars = connection to Google servers
Grey bars = no Google servers

When you open the browser does it say that there is no network coverage and you have to turn off the airplane mode?

I was having the same issue with 4.0.1, I was getting disconnect from the mobile network almost every 2-3 hours and the only way to get online again was to do a reset. But now with 4.0.2 everything seems to work fine.
My carrier (Simyo in Spain) is a "virtual operator" (MVNO), so I'm thinking that the issue was somehow related with the “data was disconnected due to roaming” bug in 4.0.1.

Been having same issues on Wifi and 3g, causes huge issues with push gmail
Edit: I removed dns changer from my phone, and seems to be helping

Thanks Menek, I am still on 4.0.1. Hopefully soon I will get an OTA update.

Hello,
This thread kind of died down but it is very important. Here is the issue logged by other users with Google. http://code.google.com/p/android/issues/detail?id=22503
Has anybody managed to find a fix?
I called Samsung yesterday and they advised me to return the phone. I don't feel like being without a phone for 2 weeks. Besides it is sort of proven that it is a Rom issue (am I correct?). What do you say guys, shall i send it to Samsung or wait for an update from Google? The problem doesn't happen very often, every once in a while. I suppose this is why the battery runs out pretty quickly as it tries to connect to a network too often. And when it doesn't establish connection it goes to Airplane mode.
Any more comments on this issue?

Radios Dropping

Anyone have an issue with their phone randomly dropping Wifi/Cell connections? Sometimes it doesn't happen for a day or two sometimes it happens 3 times in 5 minutes.
Starting to think my phone is defective...

If you are on a custom rom try going back to stock and see if it's the same. If stock try to update profile

I've tried that and it's still dropping... Would PRL/Profile also effect my Wifi connection? All data connections drop.

I'm having the same issue with Wifi. It'll still show as being "connected", but there won't be any data coming through. I'll have to toggle Wifi on/off to get it back. Sometimes it'll work for a couple of hours before having the data issue again, sometimes less than a minute.
I'm on stock, rooted.

Connections optimizer is off for me too - My phone shows a clear signal disconnect and reconnect (The wifi bars/3g symbol disappears completely) during this time all data connections fails - including texts. This is happening when I'm staying in one area so it couldn't be a tower reconnection issue.
I'm going to try taking my phone into a sprint store today to see what they say.

Ah, it sounds like our issues may be different then. My issue is solely with Wi-Fi (haven't noticed issues with 3G). When it happens for me the Wi-Fi icon in the status bar doesn't change, I just can't connect to anything.

Yup, same here. Seems like the 3G radio does the same thing, but not necessarily at the same time as the WIFI. At first I thought is was only the WIFI too, but 3G is affected, though not to as severe a degree. My WIFI was actually disconnecting and failing to reconnect. Turning off connection manager made no difference. I did however notice that the WIFI at my work (WEP encryption) never seemed to do this (at least I didn't notice), so I changed my home network WPA to WEP and sure enough, it stays connected. Was still failing to load occasionally, so I went even further and changed the router to a single channel rather than "Auto" and set it to "N Only" (due to having a similar problem with a laptop I used to have, with a similar solution). Problem fixed. I'm using an Amped R10000 just FYI, not sure if it matters. Very annoying, and given the number of occurances being sufficient to start a thread, I'm assuming this is a common issue and will hopefully be fixed by a firmware update. In the meantime, we should probably all start calling Sprint daily and complaining. Maybe they're not even aware of it. Probably not enough of these phones in circulation yet for them to worry about it.

Mine will do this from time to time. Stock not rooted. I will have full 3g bars and full wifi bars and my data will just hang. If I turn off wifi everything works again. Some times when I load a game that has to connect to Facebook to play against friends I have to close the app/game, remove it from memory and reload it to get the data to work. Same thing for Pandora. It will load a song to 2% and hang until I stop wifi or reboot the phone. It's not an everyday thing but some days are worse then others.

"Good to see" from the perspective I thought it was just me. Things described by others happening to me as well. Personally, I find I like the wifi/3g auto connectivity feature - when it works. Got my SGNII on Thurs last week, and connected to wifi at work on Friday no issues. This morning, the Note picked up my work wifi without a hitch.
At home, over the weekend, I was getting spotty connection, sometimes no connection to my wifi. (Disclaimer - I have my main wifi @ N/5ghz. An access point was added with wireless G via an old Netgear router-turned-AP.) After several attempts of moving the AP from one cat6 jack to another, I finally moved it to my main level. Oddly enough, so far, so good. Certainly possible the router's radio is pooping out.
What I notice happen with connection issues though seem related to the Note seeing my wireless G, trying to connect, but unable to do so until/unless I reboot my phone. After moving to the new location/jack, everything seems to work OK now (knock on wood).
Having said that... I also think the 3g radio (HW or SW?) is a bit wonky, as my old HTC Hero seemed to have more bars at home, IIRC. Whatever it is, just seems a bit lacking, IMHO.

Sprint is updating to LTE in many markets ive noticed my 3G drops says preparing networks and reestablishes the connection to 3G. I live in Fort Wayne and issue the permits for the tower co-locates and they are close to going live with LTE here so I know thats my problem. I can live with the flakiness for a few more days. I have not had issues with WIFI drops at home.

The same thing has been happening to me here on Long Island. 3g drops and reconnects. Sometimes it doesn't and a reboot fixes it. I also notice after the disconnect and reconnect it states my PRL is unknown. I have done a PRL update many times, a Profile Update, a RTN reset, and a factory reset. This happens on the stock rom and any custom ROM. It's driving me insane!

hmm maybe mobile settings?
Ive found LTE/CDMA setting to be not so good.
Its providing me eHRPD signal which is stop and go web browsing is murder.
CDMA only setting is providing Rev A signal fast web browsing

Sigh, so it seems as if you guys are losing wifi/3g....is it affecting voice radios or LOS/dropped calls?

I haven't been on the phone when it's happened so I couldn't tell you - Nothing like the LOS on the E4GT. When the data connection does cut out it immediately reconnects. Doesn't really impair the functionality of the phone but it happens enough to be annoying. With a 300$ price tag I expect my device to be without defect.

I'm not having LOS /dropped calls just data creep with LTE/Cdma setting enabled.
Speed test show same data speed numbers as CDMA only setting but when browsing data arrows tend to pause more making for slower page upload with LTE/CDMA setting enabled.
According to Sprint store tech such performance is common with that setting.

I am on CDMA only. I should have mentioned that in my first post. This does affect phone calls too as ill be on the phone and the call will drop and the "out of service area" message comes up. It doesnt matter if I'm on my Airave or not. I tried different prls which doesn't seem to make a difference. I am starting to think there is something wrong with the phone as my girlfriends S3 doesn't do this. Maybe Samsung will release some sort of update to fix this issue.

I made the change back to CDMA only mode this morning and it has solved my WiFi issues as well. I was also struggling getting a GPS lock with LTE enabled. GPS toolkit would show 20/21 satellites found but it would never get a lock. After the reboot back into CDMA mode it locked in 5 seconds.

[Q] Problem getting mobile data connectivity on Arc S runnig CM10

I can't access mobile data.. 2G or 3G on my phone since yesterday. Earlier, there used to be occasional signal drops, but toggling mobile data, airplane mode, or rebooting would resume the connection. My APN and account balance etc are OK. Now, voice call and wifi work ok, but elsewise, the signal bars stay greyed out, and 3G, G, H or E indicators never show - it's as if it isn't even attempting to connect to data. :crying: I also had a problem with the toggles on the notification screen not updating... i.e. showing on even though i's turned off as shown in settings menu. I wiped dalvik and cache today... but again, no change.
I tried my sim on another handset and got connectivity, though a very slow connection. This is a peak mobiole usage time here, so bandwidth may be clogged, but no connection altogether?
Any help on how to get back data connectivity would be really appreciated.
Can you please tell me if there is any way to pinpoint if this is a network deficiency or a hardware or software issue? Can the radio malfunction for only mobile data leaving voice and WiFi intact?
I'm running:

Why are you using BB64? For CM10 you should be using BB77 or above.

Actually, I got back data connectivity once before I could flash BB85.. so most probably network was a factor.
Anyway... I managed to flash BB85, and connection is quite nice, except for the persistent issue of occasional mobile data drops -(toggles not updating) . Thanks!
By toggles not updating, what I mean is If I connect the phone to 2G - and leave it, sometimes the phone will show no data connection and greyed out signal bars, even though data quick toggle is on. If I turn it off, it will not grey out. If I turn on wifi, though, the data toggle finally turns off.. and turning it on after that reconnects 2G. Any idea what causes this?
