I am running the SGSII on stock 2.3.3 on I9100XXKDJ (Which I think is the latest) and I have noticed over the last few days, that unlike my SGS 1, it seems to transfer data via 3G when I'd expect it to be using the available WiFi.
Anyone else noticed this?
Nope, it works the same as my SGS1 for me. As soon as im connected on wifi the 3G/H icon disappears leaving only the signal strength, and I am on wifi only for data.
What can I use to determine what is using the 3G Data services?
Also how can I see how strong the WiFi Signal is as far as the phone is concerned? Anyone else noticing the WiFi strength on their SGS2 is worse than on the SGS1?
Also interestingly I have both a WiFi and 3G icon on the top bar at the moment!
I don't have a SGS1 but it seems that the WiFi signal strength is not very strong on my SGS2 with KE1. Maybe with a newer firmware it is better.

Hey, I have an USA T-Mobile Vibrant.
It is rooted and running the Vibrant edition of Darky's 9.3 Final ROM.
I am also using the latest overstock kernal and the honeycomb 2.0 theme from the I9000 forums.
Enough background info. This isn't really a problem as much as my curiosity.
My phone almost constantly is switching back and forth between 3G (UMTS) and H (HSDPA) on my data connection.
It doesn't seem to affect battery life or service too much (though H might be faster), so I'm not worried; but does anyone know what the deal is with this?
Thanks ahead of time!!!

Mine has been doing this lately as well. It's only been happening since I installed my current ROM (Trigger 2.7).
Noticed this just now as well...might have something to do with the mods to show H or 3G.
I wonder if it has anything to do with signal strength. I know that shouldn't make a difference but I can't think of any other reason.

I would agree, but I went to my settings/ phone info/ signal page and the reason it was changing was because it was physically switching between UMTS and HSDPA.
Why? I have no idea.
I do live in a T-Mobile 4G enabled area, though I am not on their so called "4G plan".
I did notice that it did not have this switching problem on Bionix Frost-u2.
So, if anyone has some insight, please help us all understand

I was just watching my signal strength change and it doesn't seemed tied to the change from 3G to H.
For example, it would be around 67dBm and be on UMTS. Raise to up to around 75dBm and be on UMTS. Then it would switch to HSDPA and still be at 75dBm or sometimes lower down to 69-72dBm and still be on HSDPA.
So with that type of cross-over stats, I would be skeptical of that solution.
HSDPA is a temporary data link. If it was on continously the phone would have very poor battery life.
When network server has a data packet for your phone it 'pages' up your HSDPA capability. Your phone can also request HSPA to initiate a data transmission.
The HSPA paging process is similar to receiving and initiating a voice call.
If no more packets have qued at their server or received from your phone after some period of time it will revert to normal 3G battery saver cycling. It has to be re-paged up to reinitiate HSPA data link. The wake up HSPA function does add some initial delay.
So is there a way to force it to stay on HSPA while tethered, for example? (Or always)
hello, as the topic suggest my galaxy s 2 's WiFi is PRETTY weak.. i hv goggled and found many suffer from this problem, but i couldn't find any solution. i was hoping someone over here could guide me to some script or update to fix this..
i noticed this problem when i step out of my room bars go down to 2.. and if i go little further with galaxy s 2 then no signal, my iphone 3gs and laptop catches signal fine at distance..i have tired routers at different location's, for example my friends house, in university, so problem definitely is in galaxys2.. it may it requires some other kernel or modded stock kernal.. i dont know..
btw i was on stock ROM same problem existed there, now i am Cyanogen Mod 7.1(2.3.7) and its here too..
please let me know what more could i add that might help you guys here figure out a solution.
thanks
Well, the wifi is not the strongest ever seen but i can use it outside my house (for about 10-15 meters away) without problems
Inside the house i have full/almost full signal in every room (on every rom tbh)
So yes, it's not strong but at my eyes, looks like yours is even weak than normal
mine also has a weaker signal than my other devices. However, I ran speedtest on all of them and the galaxy s2 has the same download and upload speed as the others. This is in spite of having zero or one out of three bars. I read in another forum that the wifi signal indicator of the galaxy s2 just shows a more accurate signal strength and the others just increase the indicators to make you believe that it has a strong signal. :-D
Maybe your router wifi transmitter is weak. Also you could try a different wifi channel on your router.
Same issues here
I just got GSII from sprint and i still have my other 2 EVOs and i loose wifi signal when i go downstairs or other rooms while my EVOs get nearly full bars and speed.I never remember having any wifi issues with my EVOs.I also have the same no or weak wifi issues at work while no other phones at work have such wifi signal problem.any suggestions...?
One thing I tried which helped a little was download 'WiFi Alanlytics' from the market and select your SSID and it will advice which is the 'Best' channel strength for your router.
Ant
poor signal
Hi i have same problem with poor signal.Any solution for this !? Try connect with 5 different router same stuff....flash with many different roms and no results any ideas ?

I agree completely, but another thing you should keep in mind is which modem is the best for you, i went though and tested 20 modems and ended up with LP6 which give me good range, speed, and battery, i suggest you test different modem types
Use THIS app to check, is highly accurate
another thing worth mentioning is that i recall once reading that all kernels will not be compatible with all modem types, I use Siyah kernel, GT i9100T, and BULP6 modem
hope that helps

*Modem/Radio/Baseband is all the same thing and can be seen by going to Settings - About Phone - Baseband. It's basically a driver which receives and sends Mobile Network signals as well as handling switching between GPRS, 3G, HSDPA etc....... (but not WiFi connection, that and switchover between Mobile Network and WiFi is handled by the kernel).
Whilst you are absolutely correct in saying modem has nothing to do wifi whatsoever, why revive a two month old thread ?
I have a very odd problem with my Galaxy Tab 10.1 LTE (SCH-I905) which have not seen described anywhere that I hope someone can help me with. I am no longer seeing any signal bars instead the area has an x on it. Despite this I can use the Verizon Network and the 4G icon appears. When I look at the strength of the signal it say it is -120. This seems mainly cosmetic since I have always been able to use the 4G network and the speed seems normal. I am able to watch videos without any problems.
I cannot relate this to adding any app to my Tablet. My tablet is now rooted but I am running stock ICS 4.04 on it. This did not change when I rooted the phone. I tried removing most of the recent apps that I have added but this makes no difference. It seemed like this happened periodically before the phone was rooted. It worked fine immediately after I rooted the phone but a couple of weeks afterwards I no longer can see any bars on the cell signal meter, only no bars and an X.
Thanks for your help.
Regards,
Michael
I had the same issue with rooted stock 4.04. The bars would only show when I was in 3G coverage and 4G icon would show with no bars when in 4G coverage.
Still have the problem with Infamous 1.8.0.
So i notice that my ultra usually shows 2 bars of wifi. it goes up to 3 and then drops down to 2, even though my router is in the same room.
My laptop has shows full wifi strength and even my wife's iPhone shows full wifi bars.
should i be concerned?

download an app from the playstore, and see what signal strength you are actually getting. It may just not be displaying the two bars.
However I do find that my wifi only works 13-15m away Max. Disappointing as my old Galaxy Note has better reception.
Sadly Sony only included a/b/g/n **but not ac** with their wifi modem...

i downloaded wifi analyser.
i am testing the signal strength on the app. the phone shows 3 bars of wifi and the app shows the signal in green (strong).
so not sure what this means lol
I don't like when I connect to my 5Ghz router speed. It's kind of weird guys...feels like delay/slow. And my regular 2.4Ghz is perfectly fast.
Are you using a CM/AOKP based Rom or stock?
I and others have noticed significantly worse wifi reception vs stock.

CM10 based ROM's for the Ultra have a problem reporting/ displaying signal status.

Even for wifi signal? Thought it only affected cellular signal being stuck at 2 bars?
I found that it frequently disconnected and reconnected, with no reception in some areas that would be fine in stock and instead resorting to cellular data. Also when the screen was off it was frequently running off cellular data more often than not.

so do you guys get full signal bars for your wifi when near your router? maybe in the next room from the router?
i am thinking my ultra's wifi may be defective. my router is in the next room and all other devices show full wifi strength but the ultra shows 2 bars
Yes full bars usually in all parts of my house (up stairs and down stairs) for wifi (router upstairs)
Have you tried doing a phone repair through pc companion and updating the firmware?
i actually did repair the software and update.
Same results.
Can't say i've noticed any WiFi issues. I have full bars, and i live in a two story concrete apartment and i have a signal all over the place, and on top of that the router is quite ****ty. I'm on .257.

well its not only the wifi. today i was out and tried using the navigation app for turn by turn directions. the gps picks up my location when standing still but while moving the gps doesn't keep up. it shows me at the same location i was 5 mins ago.
i think the radios are messed up on this phone.
My GPS was very accurate. google maps and 'backcountry navigator' worked very well. HSPA+ was pretty good. signal was strong (about the same as my Galaxy S4) wifi wasn't as good as my S4.

Hmm, have you tried doing a full factory reset, or any other things? If not, do that, and if it's still not working correctly then send it in to a service center. Also, do you have the chance to try a different router, or WiFi network? The thing is to see if it's a software issue or hardware.
Hmmm...you know what? Most times I really do not care how many bars of wifi signal is displayed, but how fast the connection is. Travelling through the different locations and using hotel wifis usualy shows me 2-3 bars, but speed is very appropriate and connection stable. So maybe just this perfectionist detail is awaring you. If connection and speed of wifi was poor or permanently on the way of disconnect, that would be a problem for me...
I've had no issues with Wifi performance on the Z Ultra, I'm in the room next to the router and currently showing full bars. (Draytek 2710n)

Same here, no issues with any radio signals on the phone. If I need Wi-Fi, I always connect to 2.4Ghz for added range since I rarely need to transfer large files. Otherwise with regards to transfer speeds and signal strength, it's easily on par with other wireless devices at any range.
Hello all,
I started to have some problems with signal strength.
It's not ROM-related (currently the newest CrDroid).
If I cut my WiFi and set the phone to prefer LTE signal sometimes I'm not able to use data. It's constantly switching between LTE / LTE+.
Sometimes it will connect and it's fine but most of the time it isn't.
It only happens in places when the signal is poor.
If I set the phone to prefer 3G it works perfectly normal.
My gf got the same phone and didn't experience that issue.
I believe that for some time after I received this phone it worked normally.
Maybe it's firmware related issue?
I heard about an issue with the poor signal on this phone...
Thank You in the advance for your answers.
