Slow internet - But Speedtest results good. - Galaxy S III Q&A, Help & Troubleshooting

Hi there,
I'm getting a strange issue with internet connectivity on my SGS3.
It's still the stock firmware. However, it's rooted with the Siyah kernel to counter the audio crackle issue.
The problem is the speed. my XDA forum app, gmail and most of all Google Play store time out, yet on speedtest i'm getting 5+mbps down and 2mbps up. The browser performance is ok when this issue occurs, but certainly not 5mbps good. The issue only presents on HSDPA, and is not so bad on WiFi.
Should I flash to a new rom? Is there an issue with Siyah and the stock firmware?
Confused!

The reason why you time out might be due to an unstable internet connection, however I'm not sure how it would affect you through network data.

Please check :
- Is the DNS Server slow?
Try using an App in the market to change the DNS Server to e.g. the Google IP's (8.8.8.8 and 8.8.4.4)
- Does your APN use a proxy? (Is it required?)
Maybe the proxy-server is overloaded. An alternative for testing is to use a VPN
- When the issue appears; does it go from H/H+ to 3G and then back to H/H+? Or are there extreme changes in signal bars?
That means you've been moved to another antenna or receiver on the same antenna. Try another modem.
However take care only to use modems coming from firmwares with the same letter as your firmware has at the 4th-last position
(Eg: BLFB firmware requires BLFB modem or newer)
My timeout issue (with which I've been plagued at the beginngin) got far better when I removed the Proxy in the APN settings and disappeared on BLFB -based firmware (Omega 8.0/8.1) with the asian DXLF3 modem.

Thank you so much for your quick response!
I've added the DNS app. Hopefully I get some good results. I'm on Australia's "premium" network, but have noticed that lately in the last 6 months or so, their performance vastly slipping. Mostly due to congestion from people migrating from other networks.
The reception is always full. Even in lifts, so that's a bonus. It's just that their throughput is a little dicey in peak times. During the lunch period in the central business district, i'm lucky to get a google search to load.
There is no proxy settings in the APN. So i guess congestion might very well be the case. I was just confused as the speedtest showed that the speed was pretty good..
Thanks again for your quick and helpful response!

Keep loosing 3G connectivity

Hi,
This might be specific to my provider(Airtel) or city (Bangalore, India) so please excuse me for sending to such a wide audience. But I hope its specific to phone and there is a solution.
I keep loosing my 3g connectivity on this phone. It comes and goes and has now basically become a reliability issue. Most of the times I need to deactivate the data network mode and activate it back.
Has anyone else also noticed this?
It's because where you live 3G service is unstable, same with me also, it goes back to H+.
Regards.
or maybe you should try and change your modem.
try flashing KH1 or KH3, see if it matters..
Thanks for the responses. If its related to network, I guess I don't have a choice. About flashing the ROM, I have not yet rooted the phone and lies is still on KF3, so guess I will wait for the next update and hope things will improve.
I had some similar problems here in The Netherlands... I use a provider that is 'roaming' on another provider's network (for those who are familiar: I use Telfort, which roams on the KPN network).
The current CSC I have in my phone, is a specific CSC for The Netherlands (XENKE1). However, it keeps losing 3G connectivity over time, and I also need to reset the connection to get it back working.
For now I can solve this issue by manually selecting the operator instead of automatic operator selection. You might want to try this, it worked for me at least.
Thanks gscjot. Your solution seems to have worked. In last 20 odd hours I had to manually restart the 3g service only once. So I guess this is actually not a issue with the phone itself but the operator. Thanks a lot.
It might have something to do with the modem or CSC that is in the phone. I am currently on stock 2.3.3 but I tried Darky's rom as well (on 2.3.4). As this ROM has a different CSC, I could leave the network detection on automatic. Only setback then, is that the phone shows 'r' (roaming) on my home network and I have to manually disable 3G when I go abroad.
Best regards,
Gerco

[Q] Speed up 3G/download speeds on Optimus V? PLEASE READ!

I'm getting crappy download, upload, and 3G connectivity speeds on my Virgin Mobile LG Optimus V. I'm rooted, running CyanogenMod-7.2.0-BACKside-IHO-KANG, Build ID: eng.jerry.20111122.082819, Build Number: GRJ90 (11222011/VM670), and Kernal Version: 2.6.32.9-v3.3 [email protected] #1, and Android Version: 2.3.7.
I've read that flashing Franco Kernal may help a little bit with network speeds, but that was for the Optimus S. The Optimus S & V are pretty much the same, so would it be safe to flash Franco's Kernel with the ROM that I'm using now?
I've also read that dialing ##3282#, and editing the HTTP PD Port to value 0 and Address to 0.0.0.0 would then increase download speeds by 0.20-0.60 MBPS, but that was for the HTC Evo. I tried dialing to service code ##3282# on my dialer, and nothing happened.
Finally, I also read that doing a PRL Update manually and inserting/replacing Virgin Mobiles PRL file with a new and updated PRL file will significantly increase signal and speeds, but its risky, and requires depth to do so. Also, it allows to connect to Verizon's towers, therefore it would then not allow any data connectivity for browser, market, etc.
So, folks, my question is, is there ANYTHING or ANY WAY I can improve my download/browser speeds? Would downloading a proxy app from the Market work and apply faster speeds for downloading on my phone?
Thanks for any and all help, as it will be greatly appreciated!

It is super difficult. And really it'd be like putting a supercharger on a pinto. Sounds great when you tell your friends, but you're not going to win any races. The real problem is sprints network, and the fact that we buy the cheapest service available from people who lease a very small percentage of their bandwidth. I get 50- 125 kbps consistently. Not allot to do besides try another carrier.

Yeah for real! That's no joke lol I might try doing a PRL update tonight, but that's a big maybe. I used to get 200kbps download when I first got with Virgin Mobile with the LG Optimus V, now it seems my speeds are slowly deteriorating. And it doesn't help that Virgin Mobile is gonna bring a data cap on their 3G in 2012 to only 2.5GB, after that, they are gonna put a maximum set download speed cap after the customer uses up the 2.5GB in the month. Which sucks for me bc I'm always on Facebook, Linkdin, Twitter, browsing the market, web, downloading, etc. :/
Well social media doesn't take up very much data at all, it's the downloads that might get you if you use them a lot.

ok thanks. i may try it. still a little skeptical as a few of the comments mentioned that it broke their wifi and that the developer didn't respond to their emails.
franco's kernel is for the msm7227 chipset (unless he built one for the OS I'm unaware of,) the OV/OS have msm7627.
they are NOT compatible.
I got nasty side effects back when I flashed a msm7227 kernel on my OV for experimental purposes. it took a couple of days before it would boot consistently again even though I put a compatible kernel back on it immediately after it locked up ugly from the wrong chipset compiled kernel. It would freeze on boot until the battery was pulled for a minute or two.
I can get much better download speeds in a debian chroot on the OV with multiple download threads, using axel, but I don't know of any way to multithread downloads in Android.
As an example, my average DL speed ranges from 1-30K/sec. With axel, I can pull down over 100K/sec, with no other variables obviously changed. the Android browser very rarely goes over 100K/sec on my OV. (I am in a lousy service area.)
SetDNS (or other similar apps) "speed up the connection" by taking some of the guess work out of trying to find the resource on the web.
Most of the slowness in wireless comes from the fact that a wireless network is like a hub (in that it's a shared medium) so if two or more people transmit at the same time there is a network collision (two or more signals interfear with each other keeping the tower from understanding the request) per TCP/IP protocal all devices involved in the collision must back off for a random amount of time (to ensure they don't all retransmit at the same time again) and try again. This effect grows as the size of the wireless network grows and the more people who are on it. It effects cellular much more than wifi as you can have many more people on a cell tower as it covers much more ground.
***Intermission***
Now when your phone makes a DNS request (usually the browser, but some apps as well) there are actually many steps involved in trying to turn a url into an ip address, there are mutliple ways other than dns to turn a url into an address (most of which are legacy but it still tries anyway) trying all of these ways in addition to trying to find a DNS server means multiple request on the network which increases the likelyhood of collisions thus increasing the latency and causing timeouts (this is why sometimes your browser will start to load a page and then just hang there for awhile.)
***Almost there, Hang on just a little longer***
Now back to setDNS, this app allows you to specify a dns IP address (instead of it trying to find one) thus forcing it to use that address before trying anyother method, so your phone browser (or app) doesn't waste time looking for a dns or trying legacy methods. Thus reducing the request and collision/timeouts on a network, overall making your phone load stuff much quicker.
Works well enough that I use the web version of gmail and google reader instead of native apps (though native apps are generally quicker as they don't have to load the ui everytime you open it and sometimes the app will use an ip instead of a url, though some apps use url's in the code because the resources at needs have dynamically allocated (and thus always changing) ip addresses.)
Does anyone know if the Turbo/Supercharger scripts actually work? I assume any difference seen is minimal and also it may wear down your battery even faster. Battery life on these phones is already precious.

[Q] GPS messing with Internet navigation

Gents,
I have come accross the weirdest issue I have found on a phone. I have recently acquired an AT&T SGS II and I am using it in Argentina (rooted and unlocked) with Movistar (this is just FYI).
I am having a problem that is driving me nuts...there are times when I lose the ability to navigate the internet. Meaning I have internet connectivity, and can use other internet enabled apps (Market, Speedtest, Maps) but can't get any browser to respond (stock, Dolphin, Opera). This happens only on 3G data, wi-fi works well always.
I have narrowed the problem to the GPS. Whenever I use the GPS with Maps or GPS status, or anything that turns on the GPS, I can't use browsers anymore. I have to either restart or disable and re-enable packet data, this solves the problem until I use the GPS again...
I am running stock UCKH7 with the UCKH7 modem...the only thing I have done is rooted, unlocked the phone and added CWM..
Any ideas?

If your provider only uses a single APN, I don't know what is happening.
Dual APNs should be avoided unless you can't - mainly if your provider requires them. (like AT&T - one for most Internet stuff and one for SUPL and MMS)

Galaxy S3 Network Bug on reconnect [SOLVED]

Hey there fellas,
I tried to find something on the forums regarding this matter, but I found a very annoying bug/habit. I'm currently on InsertCoin 2.3.1 and tried a wide variety of modem firmwares, but when I'm in areas where I have a very bad signal (in the gym's basement, for example), I completely lose connection to my network provider from time to time. Sometimes, when my device is reconnecting, it cannot reestablish a mobile data connection. When this happens, I can't make or receive calls either, even though the signal bar shows a valid connection!
In a nutshell: After losing signal, the device seems to reconnect to the provider network, but not properly. Can't make phone calls, can't send or receive SMS, only indicator for this is the missing mobile data connection icon. Only a restart resolves this problem, but I'm not happy with restarting my phone multiple times a day!
Here are some topics that seem similar to my problem:
http://forum.xda-developers.com/showthread.php?t=1782204&highlight=losing+signal
http://www.samsunggalaxys3forum.com.../1214-losing-connection-cellular-network.html
As I said, I already tried different modem firmwares, always with the same result. Can anybody help me with that matter?

I have the same issue.. at first I thought it was due to the crappy network provider .. however I tried putting my sim in my old Nokia e5 and got decent signal strength even in areas where the s3 was unable to connect to the network. I faced the same problem even in stock ROM updated to latest version available for my region.
Any help would be much appreciay .

I used to have this problem with my stock ICS rom, exactly the same situation you described. Can't make any call after coming out from a tube.
I9300XXDLJ4 (4.1.1) is all good in reconnecting the signal.

Okay, after a few days of testing and trying to get a bad signal on purpose, it seems that setting up the CSC did the trick for me. After flashing InsertCoin, I had a French CSC. So I switched it to Germany and now the reconnect issues seem to be gone! There is a very handy CSC switching tool for free in the Playstore, but be careful, your ROM must support MultiCSC and switching the CSC wipes your internal memory!

[Q] Wi-Fi Problem

Hello all, I have a Samsung Galaxy S3 GT-I9300 with Stock 4.1.2 unrooted and baseband version I9300DXEMB1. The problem I have is when I try to connect with my home WiFi from my room, it says Authentication Error Occurred. I have to be directly infront of the router then it'll connect and allow me to load webpages.
If I stand in front of the router and connect, It will get connected without any problems but as soon as I return back to my room or any other place that is more than 3 feet away from the router, it wouldnt load any webpages or anything that requires an Internet connection. Then when I toggle WiFi off and on again, the authentication error occurred problem will be back. It's like my phone can only connect and load webpages when it is 1cm in front of the router. Does anyone here have any suggestion on how to help me? I'm pretty sure that it is not my router's problem because my computer and Galaxy S4 in my room can connect just fine and load webpages just fine. I've tried searching the Internet for solutions but have not found anyone with the exact same problem with range/signal strength hence I started this thread.

I had these kinds of problems with two stock ROMs, do not remember the exact versions, but when I upgraded the problems were gone. That was while using the exact same Yank kernel, so it doesn't seem kernel related. It is a very annoying bug though! But upgrading ROM will fix it, I know for a fact that GNA5 doesn't have this bug.

Here is what I did to fix my problem...
1 - Check if you have any special char on the wi-fi SSID like "!,@,',ã,á,~,ç,ã" etc...
and Remove it.
2 - On your router check if you have ip adress ranged configured like: 192.168.1.100 to 192.168.1.150, and change it to the wide range: 192.168.1.1 to 192.168.1.254
This two steps solved my problem after I have tried everything stated here and over the web

Thanks for suggestions, I've also tried Static IP and checked my router settings and that it doesnt have those punctuations in the SSID and also the start and end IP is pretty wide from 192.168.1.1 to 192.168.1.253 (I don't think that 1 difference from .254 could make a difference could it?) I'm really starting to believe that It's a hardware issue. I'm probably going to contact a person to diagnose the phone tomorrow. Maybe it could be a malfunction of the WiFi chips in the phone.

If there is authentication error then that means that the phone can detect the wireless network so the hardware seems ok. Did you try to change the router channel? And even try changing the transmission from a/b/g/n to "G only" or "N only".

That's exactly what I thought too. Why can't it connect if it can detect the network? And I've since tried changing channels only for it to return to the same result, authentication error. And my router settings do not have an option to change the radio type. I can't remember exactly where but it might be Android forums or something (read too many different forums over the past few days) and this guy said that maybe it was some power management failure thing. I'm not an expert with hardware and can't provide any explanation or theory. Maybe there's some other component that manages the power to use that'll enable the phone to receive data from the router and that thing malfunctions while the main wifi chip still works that explains why I can still detect wifi networks?
[Edit]I'm also thinking that maybe because this Imaginary power management component inside the phone is malfunctioning/not receiving enough power, that's why when im in a room different from where the router is, i cannot connect because the phone isn't receiving enough power to validate the data from the radio waves and also because when Im standing beside the router then can load webpages just fine because the Signal strength is high and probably the radio waves from the router is emitting high energy so the power management component doesn't require as much energy to receive data compared to when Im in my room. Something like the router shouting and your phone needs a certain amount of energy to hear the voice from the room otherwise you cant but if you're standing beside it you can hear it no matter what. (This is just my theory and what Im thinking the problem is. It is not an explanation but just my opinion. This information could be totally wrong for all I know.)

@Hazerm, can you try WPS setup if your router supports it?
On your phone: Settings > WiFi > Menu > WPS
Rebooting the router is also recommended. Maybe you can also try changing the security on the router to WPA/WPA2

Meanwhile, I will try to search for another solution and post it here if i can find anything.

Yep, WPS is supported and enabled on my router. Use it cause I was too lazy to retype my password everytime i flashed a firmware on the phone haha. And same thing. when I try to connect using WPS, the phone (in my room or any location 10cm or more away from router) doesnt react even after pushing the button on the router. But if I were to stand beside the router, WPS works without any problems.

Ok try using airplane mode when you are standing at a distance and check if the wireless connection continues.

No improvement, unfortunately The progress bar just crawls to the end and the phone just says WPS failed. This was approximately 1 meter away from the router, I have to be less than 1 metre from the router to get a connection. Btw, router was rebooted several times and Security has always been WPA/WPA2-PSK, not very interested in changing the security to other types like WEP. Just not very trustable

I can understand that this is very frustrating for you. Believe me, I've had issues with phones and wifi
Ok, so I found 2 short threads that you could read:
Link 1
Link 2
Summary:
- try the steps in Link 1
- Change phone frequency from 2.4ghz to 5GHz (had this option in Omega ROM 4.3-based)
- 2 users report that the issue is fixed in CM9 (or even other CM roms)
- Might be a mainboard issue after all.
PS: Surprisingly, some of the people reporting the issue have used Omega rom in the past and faced the issues since then. (I didn't have any issues though so I cant blame the rom)

Unfortunately I'm not the original owner of this S3 so I can't be sure if the previous owner flashed any custom ROMs.

Yeah, I'm suffering from OCD and just to make sure the bug doesn't carry over to the next ROM i flash, I formatted my phone through recovery before flashing the .tar firmware in ODIN. And I tried 2 different firmwares and still same thing. Now on MF6 stock 4.1.2 and trying to avoid stock 4.3 because of Knox bootloader.

Don't worry about Knox, it is not present in 4.3, so you can just flash GNA5 and be done with it! I do recommend Nova or Apex launcher though, way smoother!
For all the other people here, this is a known bug with certain routers that are not 100% compliant with the WiFi standard and therefor do not confirm the handshake. I have had these problems with certain ROMs as well (cannot exactly remember which ones) and after flashing another ROM (at the moment I am on GNA5) Samsung fixed it, while it is not even their issue, the issue/bug lies within the routers that pose problems.

Really? Because with the Galaxy S4, late 4.2.2 firmwares and all 4.3 and above firmwares had new Knox bootloaders which means no turning back to old 4.2.2 ROMs and also the Knox 0x1 flag which to my knowledge is not resettable at the time of this writing.
