So as the title says, I'm experiencing times when I have full 3G (I don't live in a HSPA + area) but the H its greyed out. I can make calls and send texts, but can't access any websites. I'm running ginger blur 3.5 but was experiencing this prior to loading it as well. I'm not running any battery saving apps that may be disabling the internet usage. Usually a reboot of the phone will get me service. Any ideas??? Thanks in advance!

This might not help you.. I use a widget that can turn on/off mobile data and sometimes it gets a little screwed up. If I go into settings > data > data manager (I believe) and manually turn it off and back on it sometimes fixes my problem. You could try that instead of rebooting sometimes ..not super helpful advice but ya never know.

Any suggestions are helpful!! I'll be sure to try that the next time it happens! Thanks

Did you configure the APN already? Did you try your SIM card on another phone to discard a problem with your line? Is data enabled in data manager?
Check those. That might be the issue
try this: http://forum.xda-developers.com/showpost.php?p=13838602&postcount=5
works perfectly here, no idea why you have to do it though, obviously you need to make sure your apn settings are correct aswell.
Hi!
Is anyone else experiencing problems with the mobile data connection on this phone? It frequently stops working. Being in an area with excellent HSPA+ coverage, this can't be a signal issue.
The phone will suddenly stop loading anything, while displaying "3G" and an active upload indicator in the notification area. No internet usage is possible in these situations.
The only remedy: Cycling "data network mode" off/on. The phone will then immediately pick up HSPA+ again, working as intended.
My previous phone (Nexus One), which I used pretty much identically and at the same places as my Galaxy S2, did not experience these stalling issues. Is this a general (firmware) problem, or should I possibly look into getting a replacement unit?
I also have this problem. My SGS2 is on O2 (UK), got the phone from P4U.
Exactly the same problem, connected through H+ with good signal, suddenly the phone will switch to 3G and I will lose my connection, this can last for minutes unless I toggle data on/off. I am on KE7, but had this problem with KE2 as well.
It sounds similar to a problem mentioned in other threads, but this is the exact problem that I am facing.
I am also considering replacing the phone (if it is a phone issue, and not a firmware issue)
Happens to me also. Very annoying

Same problem here, but i also have problem with communicating via phone. Every time it starts in home, usually morning. I cant recieve any phonecalls or sms, also i cannot call or send sms. Need to reboot, signal is -113dB and i cannot choose plane -mode, it doesnt go there. Also i cannot select operator manually. Reboot is needed every time. This scenario has been over 3-4 mornings and i have owned SGS2 about 1,5 weeks now.
I have disabled fast dormancy, and never again experienced the issue.

Yes, I think he is referring to this procedure: http://forum.xda-developers.com/showthread.php?t=1086599
It's good to know I'm not the only one experiencing intermittent connection issues - as this appears to be a firmware problem, I will wait for Samsungs next few releases to solve the problem. If the bug won't go away I might get a replacement unit.
In any case, please report back - if someone got his phone replaced due to this issue, did it fix it? Any other possible solutions?
I've spoken about this issue, the 3g itself doesn't want to work.
I've tried uskr's fix and it seemed to have worked. Also root needed.
The fix involves editing /system/build.prop
adding to the bottom.
ro.ril.enable.dtm=1
ro.ril.gprsclass=12
ro.ril.enable.3g.prefix=1
ro.ril.hsdpa.category=28
ro.ril.hsupa.category=9
ro.ril.hsxpa=3
Happens to me, can't wait till it's fixed.
Same problem with my phone
Just to let u know guys i'm facing the same issue with this phone. My data connection disappears completely bringing up a circle sign. I also lose the ability to make or receive the call. I sometimes get calls going to voicemail with full reception, when this happens I can't browse either. I am debating whether to replace the handset as I have about 4 days left to get a replacement. I bought the handset from carphone warehouse. It is a sim-free unbounded handset running the latest KE7 firmware. Any help would be appreciated as i am absolutely in love with this handset. By the way could u tell me if anyone is experiencing jagged lines while scrolling in the browser.
That's something new.
Try factory reset.

Someone mentioned loading up the phone hidden menu *#*#9900#*#* and clicking on Disable Fast Dormancy there, but not sure if that actually works or not.
in another thread i have solved this problem on my device by disabling fast dormancy. not only it solved 2g/3g issue..it also solved lost connection and battery drain.

hello iznee,
so how did you disable fastdormancy ?
i tried the hidden menu *#*#9900#*#* but it didn't work.
or did you do uskr method posted about how to disable fast dormancy ?
what about the method of editing the system.prob ?
which one of them?
please clarify
and did that solved your problem about switching from 2g to 3g ?
regards
It's not really a 2g/3g problem, more 3g/HSDPA and up problem.
And there "could" be two fixes, one I mentioned above (editing build.prop) lets call it data fix.
And the other requires deleting or editing the actual fast dormancy file as explained here
http://forum.xda-developers.com/showthread.php?t=1086599
Both are actually uskr's fixes. I did the data fix, which worked, but to make sure, I also deleted dormancy file.

sorry but just to make sure
searched, no find.
I have two consistent issues.
1 - When retrieving sites requiring a login, or when logging into LastPass, if I can get to the "Processing..." popup, it will hang and sit. Sometimes it will complete Processing... after a couple minutes, and sometimes it will continue until I kill the app. This issue is frequent, so restarting the app is not an acceptable workaround.
2 - When loading a page it will often do the same but without a popup. It will take forever to load, sometimes not at all. Occasionally I can reload the page and it will work, occasionally it will not load at until I reboot the phone or something.
these issues seem to occur frequently on home wifi. my PC, also on wifi, will load from these servers instantly.
i have had the issue on the following:
stock
Unnamed latest
Shostock latest
entropy dd latest, and last two
siyah latest and previous
with/without overclocking
with/without data enabled
affects all browsers, lastpass, tapatalk, xda premium, etc, etc.
caches cleared, including dalvik
no stress on the phone, running usually 250-500MB RAM only.
any ideas? the phone is basically unusable as a smartphone at home. the issues may or may not be as bad on regular data. TIA.
one more try... anyone help with this issue?
You state that this is mostly happening on your home Wi-Fi connection; is it possible that you have some sort of QoS / traffic shaping setup on your wireless AP / router that may be resulting in this condition? Also, do you have any of this type of behavior on cellular 3G or other Wi-FI connected networks?

thanks for the reply.
the issue is inconsistent even at home. i have been watching for causal conditions but not finding anything yet. it does not appear to be my wifi. no other devices have ever had any kind of problem, and there have been many (i share the my wpa2 wifi with neighbors as well, many smartphones, etc). yes, the issue frequently affects me off wifi on data. and yes, it occurs at my office wifi as well. but the intermittent nature makes me think it's something with the phone's software, which is why i'm focused on figuring this out here. when it rains it pours, and i will have to reboot the phone, not just kill my browser or other app, in order to connect. sometimes rebooting more than once is required.
Have you tried a 'wipe data / factory reset' in ClockworkMod Recovery?
yes, i did actually. the issue is happening even loading basic google searches out on H+. the page will usually load, but will take literally 3+ minutes to load it. i'm not sure what's going on but it seems there's something going on between me and the servers that is hanging my data retrieval. i'm mystified. but the phone is literally stuck on page loads & data retrieval about 70% of the time. i don't have any weird software running in the bg either. pretty basic Entropy DD (tried the last 2) and ShoStock latest. is it possible there is some hidden settings somewhere i can look at? i have scoured all available settings on the phone, but there's gotta be something deeper i can look at. any recommended system tweak apps for this?

ok, mine is a refurb, but has not appeared to have even a single hardware issue. guess i'll continue to cycle new software and see if this eventually irons out. next step is to get more into the system settings and investigate. my initial guess is my phone is sending repeated requests in the background.
if anyone is interested, i may have found the problem. i'm no networking guru, but i changed my phone's DNS settings to OpenDNS's servers like my home router's config. previously my phone was using Google's DNS servers. after changing the phone to OpenDNS loads are consistent and snappy like every other box in the house. keeping an eye, but so far so good.

Try to switch the encryption and see if that fixes it. If it does then this will be a confirmed issue.
I am here to learn.Thanks for sharing.
Ok it's been about 10 mins without a single drop...seems to have corrected the issue. I was using WPA-PSK [TKIP+AES] and I switched to just TKIP. I'll check back in a bit and let you know after about an hour or so. I'll try it using just AES then switch back to TKIP+AES and I will also try on 5gHz bandwidth.

Glad to see that it worked. Let me know and I'll post it up as a workaround for the time being.
Ok so it seems that the only WiFi issue I'm experiencing stems from using duel encryptions. It works fine using WAP2-PSK [AES] alone. WPA-PSK [TKIP] works fine alone as well. I played around with the settings for a bit but I couldn't seem to get it to work properly on duel encryption.

WIFI Disconnect/Reconnect Issue
Here's the issue I've been having. I'm in a very active wifi neighborhood. Even though I had the advanced wifi set to 'Always on' it kept disconnecting (and instantly reconnecting) to my network. The phone is scanning the neighborhood almost every 15 seconds. It's simply WPA-2 with just AES (and I'm not changing to TKIP)
This is a problem for me as I use "WiFI Unlock" to keep from having to enter my PIN when I'm at work/home and "Home Sweet Home" which uploads any photos I have taken to my server when it detects the home wifi network (and deletes them from my phone after 3 months).
Anyway, I was just on the chat with Samsung and in the end we did this,
1. disable the ATT WIFI auto login function (seems there's something similar on the Sprint phones that's a issue).
2. soft reboot the phone (turn off, pull battery, count to 30, boot up)
However this suggested solution doesn't work.
The wifi isn't staying connected though the breaks are very very temporary, but long enough for those apps to kick in.
Update additional things tried:
3. Turned off WiFi power save in the *#0011# service menu
4. Turned off Open WiFi notifications
5. Selected a single wifi band (5Ghz) where there is ONLY one network, mine
FWIW, I like that it connects to my 5Ghz wifi at 150 mbps, the speed is great.
Here's a video of the issue showing the phone:
http://youtu.be/FBo3NFdcMhs
Here's a videoe of the issue showing the router: http://youtu.be/rRALDc8LZOk
Yeah this is the same issue. I tried turning off sprint auto connection feature and also dialing *#0011# menu> WiFi> and disabling WiFi power save mode. But either of those had no effect after I had rebooted the phone. Maybe you should give it a try, it seems we have the same problem but with different encryptions.

I had hope for a few minutes that this would work ( *#0011# ) but it's the constant rescanning for networks.... since so many wifi in my 'hood have the channels set to auto, they're constantly changing as they compete for space. This is why I wanted a phone with 5Gh- I even set it to only use the 5Ghz* but that doesn't do it either even though I can only see ONE network with 5Ghz, mine. this phone is constantly scanning and every few scans reconnecting.
turning off the AutoNotify of open wifi doesn't help either.
It's a plot to make you use more data on the carrier's network!
*which is bad for me, since I rely on wifi which is mostly 2.4Ghz when I'm out of the house (may need some NFC tags for the car or house doors.

WIFI Disconnect/Reconnect Issue - Level 3 report
FWIW. I just got off a 45 minute call with Samsung Help Support, went to level 3 support in Texas. This is newly documented, I've referenced this forum for additional reports of the dual encryption and the wifi connnect/reconnect issue I'm having. My ticket # 2113584507 (just for disconnect/reconnect) which you can mention at level 1 as having the same disconnect/connect issue. I specifically asked if I could post the ticket # so anyone could reference it at Level 1, but they will still take your own experience down.
Level 3 said they expect that they will be getting calls today since it's the first full day after the release. So if you want it fixed, CALL SAMSUNG, they're collecting bug reports.

Up till a couple of days ago my s3 would automatically connect to my wifi signal at home as soon as I walked into my house, haven't changed any thing but it no won't connect until either I reboot or switch wifi off and then back on again . Tried rebooting phone which works for the first connection but subsequently won't connect again after sleep or at least the phone not being used for a while. Also switching wifi off and back on again works but as before once wi fi shuts down it won't reconnect by just swiping the screen and taking the phone off of standby.
Hope that was clear enough lol
Many thanks Ian

Reboot the modem/router and try again. If that doesn`t help press your wifi connection in settings and reinsert the password and reboot.

Yes I've found plenty of things relating to wifi issues on the phone but none specifically to this one so if anyone could help I would be grateful.
I assume you've tried forgetting the network and re-entering the details.
Also try playing with the Wi-Fi sleep policy, in the past this has caused some problems with the stability of the connection. Settings, Wi-Fi, menu, advanced.
Also it might be on the router side. Try changing the channel on the router, and if it's dual band set it to 2.4ghz instead of 5.

I cannot seem to get the WIFI Sleep to work at all. Even when set to NEVER on when asleep I can see in the battery stats that WIFI has stayed on the entire time. Any idea why this is?
can you tell us the ROM and kernel you are using (if you are using custom)? I have never had any issues with stock kernel myself.
also, did you hide your wifi SSID? in the past, it might cause some issues...
I was having the same problem, try this.. Setting - wifi - advanced - keep wifi on during sleep - Always.
I haven't noticed more battery use,

Also switching wifi off and back on again works but as before once wi fi shuts down it won't reconnect by just swiping the screen and taking the phone off of standby.
Hope that was clear enough lol
Many thanks Ian

if you want another option besides backing up your data, doing a full wipe, and reloading your data, try a different kernel...easy fix that seems to fix these problems most of the time...the kernel is responsible for your wifi, gps, bluetooth, cpu, gpu, etc...so swapping it out should fix an issue like that
