Wi-Fi goes slow. - Galaxy S II Q&A, Help & Troubleshooting

Hi,
I have a problem with my Wi-Fi. After a while it starts to go very slow. I have checked it with a speed test and its about 0.5 mbits. I first fixed the problem with a factory reset, but it came back after a day.
I have since found that a cache wipe, from the stock recovery menu, fixes the problem too, but it comes back again after about a day or even less.
I tried some cache wiping apps, but only the wipe from the recovery menu seems to do the trick.
I am on stock JB and I don't want to root out put a custom ROM on yet as my phone is still under warranty.
How can I find out what's causing the problem? It's getting rather annoying having to go to the recovery menu every day.
Thanks

That is strange? Maybe its an app you have installed or maybe a bug in the filmware. Head over to "samfilmware" and download the latest build for your version.
Dont think flashing official firmware from there will void your warranty as its official.

Tried flashing the latest stock ROM, same temporary fix like wiping the cache, but after a few hours, goes back to normal. This is with no other apps installed, other than the speedtest app, which I installed after I first identified the problem, so its not an app.
Another thing I noticed is that it went away after I disabled the 5Ghz wifi connection on my router, but it came back. The I tried manual wifi channel instead of auto, same thing. Problem went away, and then came back.
If I change the wifi channel the problem goes away, and then comes back after a few hours.
It seems like wifi settings must have something to do wit it, but I can find a combination which cures it completely.
Any help would be greatly appreciated, this is starting to drive me bonkers:crying:

Try hawkerpaul s GS2Nuke script, if it doesn't work try another wifi (other then the one at your home), if it works with another wifi then reset your router, if it doesn't work try making it without password.

[Q] CM9 Alpha 13 - Can't activate service

So I flashed CM9 alpha 13(after wiping) but can't get service to activate on my phone. Same problem I'm having with alpha 9. I use the activate button when it starts and it tells me it failed. Under "About Phone" and "Status" I can see that the My Phone Number setting is wrong so is the MIN.
When I call my carrier to manually activate, the short codes they give me to manually input this info do not work.
Anybody else had this problem?
Go into Sprint Zone, and try to manually activate.

I will try this. Thank you sir!!
Ok, so I wiped... Flashed CM9. Rebooted. The activation call failed, so I called sprint to manually activate again. They asked me to punch in ##971912# which is supposed to pop up a dialog screen where I can manually input MIN etc but did not. Not sure what to do.
Flash back to a blur rom activate then reflash

Ok, I've got my phone up and running on Rocko's ROM. I'm doing a nand backup now. So, to be clear... I need go to my recovery. Data Reset and wipe dalvik cache. Then I need to flash CM9. I then need to activate(or make sure I'm still activated), and once that is confirmed I need to flash Gapps?
Sorry. I'm just trying to figure out where I went wrong the first time...
Try that, you're the first person to have issues so its a new issues

I had this problem as well. I've also bricked my phone flashing an electrify pudding by mistake on my photon. My fix after fixing my boot loader issues was: I reverted to completely stock. Then I called sprint and had to reactivate my phone. After getting everything working and having a secure connection for over a day I then flashed cm7 to make sure that would work. After it did I did a says wipe and wiped everything else. And flashed cm9 then went into recovery wiped and flashed again. Then I flashed gapps and boot up. After booting up I went back and wiped again. And then used the phone for about twenty minutes and wiped and flashed "all" again. It was a long drawn out process. But I have had none of the issues that people are having on the forum. Battery life is great after calibrating. 3G is almost as fast as the 4G I had. Never have a single reboot or battery pull. Wifi and Bluetooth bead on perfect. I'm new to xda but not development. I'd post my success in the forum, but I'm not yet at ten post.

I tried reverting to stock as outlined by qbking77 but every time I sbf'ed the file as instructed I lost my recovery. The 'Unlocked' notice disappeared as it was supposed to but once I did that I couldn't get any recoveries to stick, stock or CWM, until I "re-unlocked" the phone with that sbf. Even then I couldn't get the stock recovery to write properly.
I'm pretty new to all of this. I unlocked my Optimus S and tried a few ROMs on it before I settled on Reborn Rom, but that's about my only experience with these things. I'm not incompetent(I hope) when it comes to this stuff, but it's definitely a learning curve. I'd like to master the whole process though so I can delve into the dev side of things a bit.
Joker - Thanks for the help. I'm up and running with no problems.

A combination of what you and FanBoy suggested. First I wiped and flashed Rocko ROM. Got the phone to activate. Then I wiped. Flashed CM9. Wiped again. Booted up and verified service was active. Wiped again, Flashed CM9 again, wiped again, and flashed gapps v3.
I really don't know what the problem was to start. I originally tried to flash CM7 and couldn't get signal at all. So I flashed MIUI with the same issue. Finally I flashed CM9 and had signal but couldn't activate. So the problem wasn't tied to CM9, but I honestly have no idea what I did to lose signal/activation or to gain either of those back, but my phone does work now and I've successfully flashed both CM9 and Rocko without the loss of signal or service and have nand backups of both since my biggest problem originally stemmed from not having a nand backup of my latest working set up.
I think I hear the ice cream man!

Most custom roms disallow communication from what ever it is that allows you to activate with sprint. I noticed that porting in sprintzone.apk often doesn't work and you can't activate with the dialer because it requires communication with sprintzone. So you need to flash to a rom that allows activation and then work your way back up. Glad to hear you got it working.

[SOLVED] Wifi turning on forever

I flashed clockworkmod recovery from the CWM app. I rebooted and gave me bootloop. I force rebooted into recovery, cleared cache and dalvik cache and booted fine. The problem is that wifi says turning on, but never actually turns on. After the boot every app gave a force close so I installed them again with titanium.(I don't know if it is relevant, but I say it anyway!). I am on stock, rooted 3.2. Any help will be appreciated guys.
EDIT: I tried rebooting, and activating/deactivating flight mode (I forgot to mention that I have the 16gb 7500).

Don't know if it will help but it has helped me in the past to goto settings and have it forget all the wifi connections and then when it refinds the wifi you want to use connect to it again setting it up add needed, mine was just the default settings. Rebooted and everything was good to got.

Edit: After reading your post again, I'm wondering if its even found any wireless networks.

Thanks for your time but it seems like you can't help me.. Wifi doesn't work at all!!!! That is the problem. I managed to turn it off by rebooting after turning airplane mode on and off, but after reboot when I either click on wifi or turning airplane mode off, the problem is there....

could be wrong but if it just keeps saying 'turning on' then eventually unchecks itself, this is usually a kernel module error. try reflashing your kernel and/or rom?

Well yes. I wanted to see if anytjing could be done by remaining stock. But I think it is about time to check out the ICS build. And try another rom. I think I will go for overcome. But thanks anyway!
sent from my nokia 3210
Might wanna try different options, Overcome has it's own stock kernel, aswell as ICS (Pershoots) but you are welcome to try what suits you best Hopefully the problem fixes itself, magically
Actually I flashed pershoot's kernel but nothing happened. A factory reset solved the problem, but I went on and installed ICS. It's just perfect! Anyway, it has its bugs, so I flashed overcome and everything is well Now I wait for cyanogenmod to work its magic...Thanks for everyone's help. Other thing that bugs me: If i flash stock rom from sammobile will the flash counter increase, since it will be an "official" rom?
Id like to know that too, my phone has been flashed aleast 150+ times over the past 7 months *Developer pride? * so I wanna know how to reset counters o.o
Well I have asked this question in 4 different forums and it is the third time on xda...Seems noone knows...

I think official still count's as a counter+1, but so far only Samsung knows how to reset the counter :| I think they keep it secret just so their consumer's don't sue them saying "Samsung faulty products"

[Q] GPS not working

I'm on SnowLeopard'sAT&T stock jellybean 20j and my GPS doesn't work. It actually hasn't worked for about a month prior while I was on SnowsJB v1.1. I've turned GPS in the settings and in the toggle but when I go to google maps and attempt to pinpoint my location I get the "Waiting for location" quickly followed by the "Your location is temporarily unavailable".
I've lived with the issue while I was on SnowJB 1.1 and figured it'd be resolved when I flashed a new ROM, but after flashing the stock ROM and its still not working, its got me concerned.
Anyone have any suggestions for what I can do to fix this?

I don't have a suggestion, but I'm a little surprised. I have been on SnowJB v1.1 for a couple months, and have never had an issue with GPS. It worked well, and locked position very quickly. I assume it worked for you when you were stock?
Yup everything was working find with stock. I should mention that I have flashed the new radio to no effect. I can also get gps through wifi.
I've even reset my GPS using GPS Status but its still not working.

Try turning on gps through settings instead of using toggles. Apparently if I use the toggles it doesn't "accept" the offer for blah blah blah.

If you are using twrp recovery try cwm, it worked for user dbgeek in SlickJB thread.
I was using CWM, tried 3 different roms, flashed mako radio, JB radio, and now LGNPST....and still the gps is not working. is my phone ****ed?
It was working fine up until today when I felt like trying a new ROM, I was on snowjb, with the new modem working fine. As soon as I flashed GPS no longer works. Not even the icon comes up, like the hardware is on but not doing anything
I'm on cwm. I'm thinking I LGNPST back to stock, update via the OTA and see if that fixes things.

Ok got it working, here is what I did.
1. Downloaded ICS modem, flashed it cleared cache/factory reset/system
2. installed slick rom v2 (slick rom is the only one that has worked, tried a couple others with this method)
3. at this point, the gps icon was flashing but not locking, either way a good start. So I went into cwm, cleared cache, factory reset again and flashed the at&t jb modem
4. Reboot, viola it works.
I don't know why it'sd not working on nocturnal or snow's rom. Hope this helps.

After you get it working on Slickv2, you can restore your back up, hopefully you made one, then you re-flash the JB modem and you should be all set!!
Note: When I restored my back up, I advanced restored everything but cache. Don't know if this makes a difference or not.

Yeah same for me. GPS worked on Slick, then flashed back to Rootbox and it didn't work. Waste of time but at least maybe this info is helpful to find a solution for all.

[Q] Unable to call or SMS and global mode

Hello!
First things first, I have searched the internet, not just XDA, far and wide for these problems. I have followed nearly every lead I could find before creating a post about this, I am at wits end and at this point have had to remove the phone from the premises before something bad happened to it.
My problems:
"Switch to Global mode" constantly pops up"
Cannot send or receive either texts nor phone calls
Setup:
Previously on CleanRom 3.5, decided to try CM10.2. Downloaded and installed CWM to use instead of TWRP, downloaded CM10.2, wiped cache, factory reset, installed CM10.2 zip file as well as Gapps for 4.3. CM10.2 exhibited the above behavior. Currently I am sitting on completely stock JB 4.1.2, the details are below.
Network: Unknown
Mobile Network type: Unknown:0
Service State: Out of service
Mobile Network State: Disconnected
Phone number: <correct #>
IMEI: <correct IMEI, validated per inside battery cover>
Android 4.1.2
Baseband: I605VRAMC3
Kernel: 3.0.31-1098177
[email protected]#1
SMP PREEMPT Fri Mar 29 10:58:51 KST 2013
Build Number: JZO54K.I605VRAMC3
Hardware Version: I605.06
Mitigation attempts:
Downgrade to CM10.1 (AOSP keyboard would not work)
Tried various AOSP and TW ROMs, to no avail.
Cleared cache, dalvik cache and factory reset between each attempt
Finally downloaded stock ROM, followed steps here (great guide btw!) using Odin, no change.
I truly don't know what else to do at this point. I feel like I've done everything I've seen and my problems are still around. I see a lot about IMEI (not sure what it is or what it does), but mine is present and has been throughout this ordeal. Occasionally my phone number would read as 000-000-3279, which was not correct, but that was only on the CM ROMs. Any help with this would be greatly appreciated, I don't want a Note 2 paper weight or media device hanging around, I want my phone back - stock form is fine. Thank you for reading all this and I appreciate any help that can be sent my way.
I am in this exact situation.
Was on stock, VRAMC3 and wanted to go custom.
The CASUAL exploit worked just fine, and once I had CWM I attempted to flash CM 10.2.
It just didn't seem right.
Every other ROM I've tried since that point I am unable to send/receive texts, and get the Global mode popup constantly.
I tried to revert back to stock via this thread: http://forum.xda-developers.com/showthread.php?t=2024207 But no luck.
Any help would be appreciated.
I ran into this last night while trying a new rom(coming from Beans 22). I can't call or receive calls. I can receive texts, but can't send them. Data works. I've tried multiple ROM's, and it's the same situation with each(CM10.2, 10.1, XenonHD). I just tried returning everything to stock with Odin, and continue to have the same issues. My phone number reads as 000-000-2780. My IMEI is correct. Service State: Out of service. If I switch to CMDA/LTE, I get hammered with "switch to global mode" popups. If anyone has any suggestions, please post them.
I had LTE and wifi when this happened to me, so I was able to download Telinfo from Play.
Also, I had ODINed back to Root66 so all the hidden menu options were available.
Your modem needs to reset, so go into device info and turn off your radio. Toggle to LTE/CDMA/EvDo and then turn radio back on.
I don't remember if a reboot was necessary.
My modem was fine after that.
Let me know if this works for you.

hi.. same thing happened to me. Was trying different roms coming from Beans22, lost ability to make/receive calls but data connection was fine.
Questions:
Did you have to change rom back to factory stock before doing the radio toggle thing?
What is "ServiceMode Shortcut"?
Thanks much!
wutek, I did change back to factory stock before I did the radio toggle, but I think you can do it from whatever rom you flashed to. "ServiceMode Shortcut" is an app from the store that allows you to access the service mode menu. After installing it, go to testing>device information, and reset the modem from there as pdinphx advised. Good luck!
Having the same problem. Flashed 10.2 last night from cm11, didn't make a call just went to bed and woke up and had this problem. Tried using that app from 10.2 without any luck unless I am doing something wrong. I guess I am gonna try after using Odin. Anyone else having any luck?

wutek, I did change back to factory stock before I did the radio toggle, but I think you can do it from whatever rom you flashed to. "ServiceMode Shortcut" is an app from the store that allows you to access the service mode menu. After installing it, go to testing>device information, and reset the modem from there as pdinphx advised. Good luck!

hi ap0ptosis,
quick update... I was able to regain radio after odin to root66, toggle using telinfo, factory reset. Thanks for the info on the ServiceMode Shortcut app.
To all.. thanks for the help... I am back and kicking. However, I am now staring at the big elephant in the room so have to ask the question... how did this all of the sudden start to happen? It started for me when I tried out some 4.3 Roms but radio going bonkers did not happen immediately. For me it happened overnight w/o me touching anything. The message I would continuously get is "Mobile network not available" . Also phone would keep asking to switch to global mode.

Glad you got yours going. When using root 66 do I still need to use the pit file alongside? Have the 66 downloaded but never used it.

hi mikelikesbikes.. I followed the exact instructions from the below url. So definitely, I used pit. Good Luck

Have Odin running as I type using root 66 and the pit. How does one reset the radio from the playstore app? I see how to turn off the radio and change radio but not how to reset it. Obviously it is staring me in the face.

So I got it going. Used the root 66 file and didn't have a operating system to boot into, only cwm recovery which was weird. So I used Odin and went back completely stock, and ran that app from the play store. Still didn't work until I factory reset from within settings and that was what got it I suppose. I wonder also what caused it and why others had the same issue on the same morning. Like I said previously I was running 4.4 for a few days and went back to 4.3. That's the only thing I did differently. Anyway, ran Casual, and running Beans 22 and happy.

Hi mikelikesbikes,
Glad u got it working again. Interesting... I did read somewhere that root66 may not work and if so, to use vz stock.
Correct, factory reset is within the phone>settings>backup reset menu... cheers
Not sure why this happens but I had the same thing happen to me. I tried cm11 and then switched to cm10 after switching back to tw rom I was in roaming only. A simple factory reset took care of the issue. So I think the common denominator here is the series of events cm11 to cm10 to touchwiz....

I had this problem coming from stock MC3 --> Root/Unlock --> CM 10.2
No calls / SMS on 10.2, and still nothing coming back to stock MC3.
You guys saved my ass, thanks! Toggling the radio / factory restore worked for me.
Anyone know what ROMs are SAFE to use without this issue appearing?
Back to normal, whew!
I had been stable on cm10.2 nightlies as of 11/29 with mc3. Installed cm11 everything was operational. I was able to bounce back and forth between my backups. As soon as I updated to the newest nightly for cm10.2, 12/1, that broke my voice/sms.
Ended up reverting back to stock, factory reset from settings in stock and was back up and running.
From here I used casual and tried to go back to the 12/1 nightly and still had the same issues.
Repeated stock process/casual and am now on slimrom 4.3 mc3 and running smoothly. Just wanted to get my problems and solution out there for more info.
This was a fairly common problem with the S3.
The key to fixing it is not in the factory reset but in the reprovisioning of the phone's modem, which typically requires a stock rom to access Samsung's hidden service menu.
Incidentally, even a touchwiz rom built off another carrier's base (or international base) can trigger this problem.

Agreed. Never had this problem before (thankfully). Think it's odd though several people had the same issue on the same morning.

Same Issue
I'm running into the same issue as ya'll. Flashed CM 10.2, than flashed back to CleanRom 3.5 and not able to make calls or send text. Can receive text and all incoming calls go to Voicemail. I ODIN back to stock VRALJB, can't seem to get phone going again. Tried toggling Radio and Factory Data reset, but now the phone is just stuck in Roaming Mode. Any help?

Note 2 rebooting

I have a note 2 that I kept stock for a long time. And decided to root it about a week ago. I used the latest casual one click root. And it seemed all dandy initially until i went between a few different roms and it decided it wanted to shut off randomly and not boot back up past the note 2 screen on its own. But the odd part was it booted while connected to the wall or to the computer. So I flashed to 4.1.2 stock via odin and the issue still remains. I can only use it fine on charger. Is there something else im missing on flashing back to stock?

Hmm when you installed 4.3 did you do so wiping everything could be an app causing the problem. Try it from brand new with no apps installed and see if that helps. Could be also a radio issue as well.

Yeah I wiped everything. Actually used odin twice to revert to stock 4.1.2. I tried a few cm nightlies before it began. Is there anything else I should flash on top of whats already been done?

I've found that even after using ODIN to go back to stock 4.1.2, that there's still leftover data on the phone from custom ROM's. I've read where others had the same issue. I don't know why Odin doesn't seem to fully wipe everything ... but this has been my personal experience.
The way I've fixed this (and all this may not be necessary).. . is that after Odin'ing back to stock 4.1.2, I boot into stock recovery, then do a full factory reset and wipe cache. Then I booted into the stock Rom and used the bypass setup trick (touch the left side of the screen right above Emergency... then right side, then left, then right again, and then volume up... this should bypass setup to save time).
Then went into phone's settings and performed a factory reset from within the stock Rom too...
Finally... (because I'm a bit OCD... so this is probably not necessary), but I ODIN'd back to stock 4.1.2 one more time and then proceeded with using CASUAL again to root /unlock the bootloader).
I know this is a pain in the butt... but this has worked for me. Maybe others will have some better suggestions.
(Edit : Forgot to mention that if you're not wanting to return to stock to start over again... check out this thread (http://forum.xda-developers.com/showthread.php?p=53624921) on how to flash a stock recovery for the purposes of doing a proper data wipe... then can you odin your custom recovery back to the device without having to fully restore to stock... this can be a real time saver. Please make sure to thank the OP for the helpful info).
So in the end I tried to reset from stock recovery and wipe cache. Than do a reset from the settings and the issue presisted. But now I have root and recovery as well. So I may give a rom a try.

This is totally a guess, but I'm thinking that you may have a battery problem... and it's just a coincidence that these problems started happening around the same time that you rooted. You may try replacing the battery to see if that fixes things.... (you can get one pretty cheap off ebay or Amazon).
Yeah thats odd. I had bought another battery from a phone store I use to work at and have no issues now, back on 4.1.1 rooted.

Cool. Hopefully you'll have no more problems with it for a while.
