[Q] Constant switching between 3g/h/h+ - Galaxy S II Q&A, Help & Troubleshooting

I have looked around and found other threads discussing changing between 3g/4g however mine seems to be far more quicker and unreliable than it should be, I have had this problem on kg3/kg6 but dont remember older modems.
Anyway I will be on my phone and within a minute time it will switch 10+ times between all three networks. Im also getting very unstable network connection and the network is slow which it should be a lot faster.
Is this a modem issue or kernel?

I noticed this as well since picking it up yesterday. At first i thought it was doing this when it was sending and receiving data but that isnt always the case.
Im on Cognition 1.31 with KG3 but also saw it on stock KG6

Yep, same issue here. My data is very unreliable and slow as hell at times. Just got the unit yesterday and it's already annoying the hell out of me.
When it works, it flies. Unfortunately, the radio of my Chilean SGSII seems to be unable to maintain a solid working connection under various signal conditions.
This is pissing me off and making me want to return this to Amazon. FWIW, I had similar data connectivity issues with an unlocked Nexus S (i9020A). Mostly slow data (like 300kbs on 3G slow). I tried three units and gave up. Is this a Samsung issue?
Would flashing/rooting/installing a custom ROM fix this? If not, it's back to my Atrix.

I may have just solved this by disabling fast dormancy (*#9900# in the dialer) so far it will switch but more when I'm not using the internet. And speeds have shot up! Does this work for everyone else?

The fast dormancy trick really didn't do anything for me, unfortunately.

signal/data issues...

Hi there
long time reader first time poster here...
searched and found nothing...
running the latest gingerbread AT&T official on a AT&T atrix (currently unlocked and running on the Rogers network in canada)
i seem to be having an issue with my Atrix lately(or at least been noticing).... normally when i am connected to the data networks fine, my signal meter and H+ are is blue...
what has been happening is if i leave the phone alone for some time (usually 20+), it just disconnects from the data services... all my signal meter and H+ meter turns grey... when i "wake" the device it takes a couple seconds to kick back to blue... when this is going on i go into my gtalk and i see it had signed me out and that its trying to sign me back in.... same thing with alot of other apps, like my issimo app, its been sign out, or hasnt received any new updates since it turned "grey".
how do i stop this? is this a bug? something wrong with the OS? will i have to reflash?
any thoughts on this would be appreciated!
thanks!
UPDATE:
had battery save mode on nighttime, so i thought that was the issue... so i changed it to performance and doing that had no effect at all... still losing data after a while of it being locked...
any ideas? could this maybe be some residual affects from a battery saver app i add?
i really would not like to reload the OS...
anyone got any ideas?
i'm finding any solution for the same problem, some atrix lose data signal, motorola says that is a software problem but i dont find a fix for that yet, any idea?
It's a software issue on Motorola's end. I'm having the same problem. I haven't flashed a custom ROM yet, but my friend had the same problem and he said when he flashed Gingerblur it was fixed.
when i seemed to notice it was when i had upgraded to gingerbread... so what i simply did was deleted my APN, rebooted and entered in the APN again, and that seemed to have solved it
@OP I don't use GTalk so I can't comment on that, but the signal than that you described is EXACTLY what my SGS does running on stock Froyo rooted.
I don't know if its more battery saving or what, but I tend to miss more calls in weaker signal areas when my phone has been on idle for a while.
I too am looking for a fix because of that. Also my Atrix sometimes acts the same way on Froyo, but I haven't used my Atrix in a while...

kinda still having the issues but i have been dealing with it and trying out different ROMs to see if those are any help at all... so far its intermittent
Same kinda style here ..
When i am on my mobile data it's fine , but as soon as i connect to a wi-fi it become grey and no more data (mobile/wireless) is working ...
Tried many ROMS , Radios , all the same...
That new leaked radio they got doesn't work here in Bakersfield the 1.77.36p
Shoot I was lucky to get 00.04 mbps download and 00.01 upload
When I reflashed the previous radio I got 05.00down 2 up mbps much better one

Yes I found this to be true as well. The new radio (1.77.36) dropped signal for me often and the speeds were lower than with 1.77.30

why not upgrade your radios to the latest AT&T has to offer? 1.97.00 see if that helps?
im having the same issue
anyone knows why this is happening? i have cyanogemod 7, i reflashed the phone, and when it started i restored but the problem just keep going
I have a very similar problem. When the H+ is lit up blue I have a network connection. But it will switch to grey then internet ect stops working ..still have signal (4 bars) any ideas why it keeps switching?
I've had the same issue ever since I first got my atrix. I've tried many different roms and it does it with every one. Ill have great signal n my browser will direct my to a no data connection page. I have to reboot or turn airplane mode off n on to get it going again. I have like a month left on my warranty gonna try n swap it out n see if a different one will fix the problem

[Q] Gin-Sen-Tazz Data Drop Issues...

Hello,
I have been having some issues with the Gin-Sen-Tazz Rom for Eris. First of all, this ROM is AMAZING. It is extremely smooth and easy to OC my Eris on this one. The only problem is that my data just drops on its own. Now, I've been wanting to list this on the [FIX] 3g Data drops on GB Sense Roms Thread but couldn't due to my less than 10 posts (or post it on the actual Gin-Sen-Tazz ROM thread). I'm not sure if my problem is the same as those on the [FIX] 3g Data drops on GB Sense Roms Thread. I've done those steps but still it just drops. The way it does it, usually when the screen is off and after a while of inactivity, it just goes out (the whole 3g/data). As if I manually turned off the data. When I try to turn it on (either via the widget/shortcuts or through Settings) it just say "turning on..." but doesn't. I have reverted back to a different ROM but remember something saying about..."Radio" something something in the "Wireless Networks / Mobil Network" check box. The data will never turn on unless i Restart the phone and even then it turns off after a while. I've installed the ROM MANY times, done all the wipes, all the Reverting Back to Stock and all that and avoided doing the *228 AFTER the ROM install. I'm hoping one of you genius' who are inventing these things, and by the way - GREAT JOB! could help me out. Please let me know if I need to add something to this lengthy question.
Thanks!!!
Does data work alright when running stock 2.1 after flashing Flashback21 v2?
I'll post a link to your question in both the 3g data drop fix thread and the Gin-Sen-Tazz thread so more people can come and help you figure this out.
Thanks for putting this in the dev forums for us... I'll have to load up gst in the am and check, but if I'm not mistaken, there are some powersave settings that might affect that. I'll report back tomorrow.
thanks!

I'll do some digging around when I get a chance too. What radio are you using BTW? Not 100% certain its that but I know on inc certain radios don't play well with gb sense. I know when I was running gst with the hero radio I didn't have and data issues but I did with the radio from Eris ota. I'll do some digging though and see if I can find anything. One thing you can try in the meantime though. Instead of rebooting, have you tried switching airplane mode on for a few seconds then back off? Doing this usually got my data back on for me instead of having to reboot.

The 3g drop is a known issue w/that rom. It happened daily to me the entire time I was using that rom. If you reboot the phone, like the others said,you will get the data connection back. I think the airplane mode trick works too.

Yes, Sir. Works like a charm...I'm using xtraSENSE right now and it works great. I've noticed, you know how on some phones/ROM's you can go into settings and have it automatically turn off data after so long of not using it. I've had that option on my Thunderbolt (when the screen is off) and when you turn on the screen the data connects, well, its kind of like that, except, it never connects and the setting reads something like "Connecting to....." can't remember the rest. I've noticed the xtraSENSE automatically disconnects data but connects perfectly when I turn on the screen.
Thanks!

CS, yep I've tried the Airplane mode. When I do that, the mode turns on, when I turn it off, the data still does not connect...as far as Radio, I'm not sure where to find that (I even tried googling it). However, when I used that link to revert ALL back to stock and there was that option to do the radio thing as well, I did that step, too. I hope that helps and thanks a mill!

Yep, Powersave Settings lol that's the name I was looking for on my previous post. And that's a great way to explain it. I think, if that ROM had an option to turn that powersave feature off, I think that would be nice only because it would not turn off on its own. But that just seems more like a shortcut and I'm certain that, for you guys, its a piece of cake to get to the root of the glitch.
THanks!!

Yeah, I wish it'd work for me. Its a great ROM, I'd put up with it until it would get fixed.
yea post 3, 4 idk 5 more minutes
I'm ganna try turning the power save feature off on this Rom and see if that works. Great idea, never noticed that before. Only thing is for me it seems to happen more often when I receive a text or a phone call when my phones locked (or "off"). I did notice that when my phone is active and I'm using it, I see the data turn off (3g icon disappears) and I just get my phone signal, whenever I recieve a text or phone call. I have not noticed this before on other roms. But then again, I have been known to be very un-observent before....

Dunno if anyone is still following this thread, but I've had a small breakthrough with the data drop issue in the sense gb roms 3g drop issue. I had power saver mode disabled all day yesterday and my 3g never dropped! Still to early to say if this is actually working or if i was just lucky, but in my experience my 3g would drop at least 1 time a day and sometimes more. So far so good. I will report back again in a couple of days of testing to let you know if this is a working "fix".

Phone seems slow on home wifi..

I don't know if its just me but, my phone seems slow while on my home wifi. I haven't checked wifi anywhere else. And my signal on the phone seems to be weak at times even while sitting in the same room with my router. My cappy seems faster in this area. Also streaming some video seems to be slower on my sgs2 vs my cappy at times. Any tips/advice...?
BTW..my device is vanilla as of yet...
Sent from my SAMSUNG-SGH-I777 using Tapatalk
Well, at present, I'm on Cognition. So, I can't give an exact parallel as far as circumstances and setups; however, my phone is extremely fast when running on my wifi connection at home. I haven't really focused much on the reception, but from what I remember it has been excellent as well. If I'm in the same room, it's completely full. If I'm elsewhere in the house I still tend to have decent reception(more than just the one bar).
I'm not sure what to suggest for better performance outside of possibly considering flashing an alternative ROM instead of just running it stock. The process, overall, is honestly quite simple. I do understand though that some people like to run the phone the way that it came out of the box. It's just a suggestion.
Outside of that I mean maybe an issue between your router and your phone, but honestly I doubt that.
I appreciate the response. I'm puzzled by this...as I am no expert I'm also not new to flashing roms. My cappy is on a modded rom. I'm just giving the devs time to work out the bugs! Thanx again!

The BCM4330 used in a LOT of mobile devices just plain doesn't seem to like some routers.
At my home, the signal strength always looks low before connecting on my GS2, Tab 10.1, and Infuse (All BCM4330) - then it suddenly looks better when I connect.

Hates D-Link (battery drain, loss of range).
Loves Netgear (less battery drain than HSPA, excellent range).
At least that's the case with the international version.
Have a NetGear and my wifi flies. of the couple dozen or so routers I have set up for family and friends NetGear seem to always be the easiest to set up, connect the most consistently, and give the best all around speeds for both net surfing and console gaming.

My phone was downloading normal speeds earlier. Then I rooted in and flashed Cognition X2 beta 4.
Now my speeds are REALLY slow. (takes forever to download something as small as 4 Mb...)
Idk if anyone else is having the same issue
check your router for firmware updates, if there are, appy them and then retest if your speeds are still slow
Interesting..as I am using a d-link gaming router. Will have to check into firmware update..had the router a few years never updated it.

Huge WiFi Issue

Ok so first off my internet connection is perfect, and it isn't my internet because my internet works fine, now to my issue....
My WiFi on my amaze turns off by itself every 5 minutes, but not only that it throttles and I can't get a stable connection to my internet, I tried loading google and it took me 5 minutes because my WiFi was disconnecing and not working even though I have full signal
It's not my Rom, or any Rom (it happens with my Rom, Mikes rom, and NRG's Rom)
It could be a hardware issue but I doubt it because my data connection is fine, although my connection has been weaker ever since this has started happening, any advice? Could be a radio issue but I havnt flashed a radio since the first leak so I dunno

Does your security use WPA? I know that for some routers, the WPA handshake interval (also known as Key Renewal Interval) can be set too low. This is not something you can change with your phone, but with your router. I find that anything below 3600 *CAN* cause problems. Try changing it to 3600 and see if it improves.
Stupid question: Do you have the "Best Wi-Fi Performance" option selected? I find it that it helps sometimes.
No its not my router, my iPod touch 1rst gen loads pages fine, aswell as my old mytouch 4g
SuperSayain Sense 3.6 coming soon
I have WiFi issues as well...I always reset the router everyday just to deal with it. The only time it works better is with stock. ICS or GB I don't have issues...only Roms.

My real world experience with it seems good .. but speedtest.net app shows only 5mb/s when is usually close to 15mb/s on hi.gingerbread (i pay for 15gb speed, so it made sense).
It never times out or has a hard time connecting tho
I'm running stock rooted .3 ics... Interesting find. I will keep an eye on it myself

Tried resetting your wifi router? That could be the issue, since I use both wifi/3G on the leak and official updates, both are fluent, hence the idea of a hardware issue possibly, but you can try reflashing the latest radio file. And I don't think wifi should affect network data, sounds like a hardware issue with that for sure.

I know, but it seems that the Amaze can be a bit sensitive. It wouldn't hurt to check the interval. If it's at 3600, great. If not, change it to 3600 and see if it improves.
It doesn't have to do with our routers. At least not mine. On GB, never experienced this issue. Same phone but now with stock .3 ICS I have trouble with connection and speed over wifi. Same at work. It must have something to do with the new ICS radio because I've experience the same issue on ARHD 2.2.1.

Then reflash the radio, see if it helps, my reception actually increased with the update, from 5-8mbps to 12-25mbps.
I should also mention that my wife's GS2 doesn't have WiFi issues. Stock GB...she won't let me do anything to her Sammy.

Done that. Flashed first leaked ICS - wifi issues. Flashed ARHD 2.2.1 - wifi issues. Flashed latest leaked/official ICS - wifi issues.
On the network, I get great signal and 23mbps in Beverly Hills. Wifi is just slow and weak. Pay for 10mbps download but phone does half of that.

Actually I was talking about network speeds, my wifi speeds are about 12-25 always. Maybe you should try a complete system wipe using the wipe script then reflash, just to clean up any old files lying around that may be blocking things up.

WIFI is terrible (is a fix even possible?)

Hi,
Love the phone, but the wifi is so bad it is ridiculous. First of all, I always have to do *#0011# to disable wifi saver otherwise is it completely unusable.
But even then, it randomly disconnects. Seems this device is simply unable to deal with many APs or many networks. It is completely useless for VOIP because of this.
Is this going to plague this phone always? Meaning: is this something that can be fixed by custom roms and or kernels (I know samsung will prolly never fix)? Or is it simply the hardware that is badly designed and will always suffer from this?
FWIW this is not a universal problem. I usually flash a new custom ROM version about once a week to keep up with the latest ICS firmwares, and have never had any wi-fi connection issues. I'm often on 2 wi-fi networks throughout the day (one at home and one at work). I've never done the *#0011# trick or anything like that.

I do wonder if it is hardware related then...
My understanding was that this is very related to the routers. All my APs are running dd-wrt. Very annoying to see my iphone and ipad never having these issues whereas my daily driver (the s3) is pretty flaky. Maybe someday there will be a true fix!
No issues here either. Have a multi AP setup at home and work with upwards ten SSIDs at work. Mostly g/n networks. 2.4 and 5GHz works equally well. No problems anywhere, not even in town at cafes or my parents crappy Thomson all in one ADSL modem/router.
Using AOSP but Sammy original worked fine also during the first and only hour of use.

Did you update your phone? The update fixed my issues with WiFi and haven't had to enter the screen since, and yes WiFi is really good now
Dude, my s3 wifi adapter is very good. you should analyze your wifi AP and see who is sharing your channel frequency . Most people use same channel 6 by default. Channel 1 is the least used IMO and it's clean. If 1 and 6 are often used then use 11.

My main APs are on ch1 and ch11. Other networks are far away (no interference, and signal is pretty clear.)
To clarify: when I do the 0011 trick, my wifi is pretty stable, but disconnects from time to time making it too risky for me to get on a VOIP call for fear of disconnection. Speed is great though. And every once in a while, it will simply not switch correctly between my two networks (one in house, one in garage), it gets stuck on 'getting ip'. I then disable wifi and reenable, which fixes it. (thank god for WiFi Manager Premium's widget)
It is not unlivable, mind you, but it is pretty crazy annoying. Especially when ALL other wifi devices I have never have any issues.
Will try a full stock reset when JB comes out officially, that always seems to help in the many wifi threads I've read in the forums thus far.
this fixed my wifi problems when I was getting very slow speeds in the last few JB leaks

I will certainly give LH2 a try then. I had (wrongly) read that the post-LG8 updates didn't seem to change a whole lot.
I recently had all kinds of strange problems with my phone. Charging slowly.. wifi was terrible. The rom i was running made no difference.
In the end i was going to send it back as i thought i had faulty hardware. The day i was to get it sent off.. i thought what the heck.. ill try a .pit file to force a full repartition. And its only gone n worked!
Phone is back to running how it should.
I would be VERY careful flashing .pit files tho... is always a last resort.

Hi,
I had exactly the same problems with wifi like the OP! My S3 was always either not connecting nor finding networks. Sometimes it worked and then the phone was loosing wifi all few seconds... reconnecting. Using skype was not possible!
Above that, pressing power-off to send S3 to sleep was not responding everytime... sometimes the screen stayed on but touchscreen was not responsive. Then power-on again it was not responsive, too.
So a lot of problems with a device at this high price...
After nearly 2 weeks I've sent it back and got a new one. Now everything works perfectly!
Both devices were updated to newest update LG8.
If it is a software problem, there is maybe something going wrong while updating, otherwise I would say it's an hardware issue.
Good luck!
I don't know the topology of your home network or equipment. But routing with Nat, and two different network using the same private ip address range could cause issues. Again I have no idea what's up with your network. Are you running a essid or two different networks?

Doubt it, simple enough setup. One main, one wired AP (both on same SSID) and a repeater bridge for garage, diff SSID. No problems with the laptops, apple devices, etc.
Will test out every kind of wipe/flash... I fear exchanging it will be hard seeing as this is an unlocked international version bought in Canada online.

I have more signal than in my sgs1.
Currently using LG8 plus siyah 1.5.2.
I would exchange it.
