[SOLVED] WiFi not working properly? 3G/4G stays on due "My Account" App

So when i am home i have my WiFi on, which means my 4g is off. Now when the WiFi is on, i can not receive or send pictures. Also cant use the web or do anything like that but just send and receive text/calls.. and reason to this? maybe i have certain settings on that i don't know about? If i remember right, my wifi worked properly a few days ago.. but i cant remember exaclty. Help please? Thanks

no one knows?

Power cycle your router?

I've been having a different wifi issue. at home I have only edge coverage but I have petty good cable internet so obviously I want to use my wifi but for some reason the phone connects to wifi yet still uses the mobile network unless I turn off mobile data. My wifi sleep policy is set to never btw. Any ideas?

Edit
Also if I turn off mobile data while connected to wifi then turn it on while still connected it stays on wifi fine. Its like the mobile radio is preventing the wifi connection from fully initializing or something

Same issue!

I am having the same issue. I have to go into airplane mode, then turn on wifi to actually be able to use it... otherwise seems to default to mobile radio...

I have the same issue..this is what i do to work around it though:
1. Go to Settings>Wireless and Networks>Mobile Networks
2. Uncheck packet data, and then check it again.
Once i do this, my wifi works again, let me know if it works for you.

Got this from the battery thread. This actually fixes the wifi issue on my SG2
The program is called Llama and can be downloaded from the market. I deleted all the default events and just added these 2. Hope this helps for all of you with this issue.

Try freezing "my account". It toggles data even with WiFi is on. Try it and let me know.

Actually saw this tread and had Llama installed with these 2 profiles added and was till getting this issue... Going to try Freezing My Account to see if that helps... I know it helped with my wifi issues on my G2x.
Update: Nothing seems to work now. Can't have Wifi and cell radio on at the same time... can get calls but nothing else...

I've seen it occasionally as well. I haven't needed to reboot though. It usually recovers after I toggle WiFi on and off and mess with some other things.

Yes, either return or warranty exchange for a new one, I have not noticed this issue with my device at all.

I've been having the same issue and it definitely causes excessive battery drain. Sometimes toggling wifi off then on works. Other times it requires toggling mobile data off then on.
I had it happen just now and tried freezing 'my account' in titanium backup as suggested and my 4g indicator immediately turned off. Sweet! It seems that 'my account' is the culprit!
Edit: I really wish this topic wasn't merged...I think there were a couple 'wifi problem' threads talking about different issues. To clarify, my problem was that while on wifi my 4G indicator would sometimes turn on and consume more battery and (sometimes) force all data to use 4G instead of wifi. Really annoying!

[HOW-TO] Get a Data Signal While Roaming

Background:
Ever since I've had this phone I couldn't get a data signal while roaming in areas where I knew one was available. Old phones would get data while roaming without a problem.
The Epic Touch would just give a notification saying "you have lost data connectivity" or something.
I understand certain Sprint roaming areas just plain don't have data available. This howto can not fix that.
What this howto does help you do is get a data signal while roaming in areas where a roaming data signal is available.
Credit:
This was apparently discovered by someone on the sprint forums, and I found a reference to it on the Android Central forums, so I do not know who credit goes to for discovering this.
What to Do:
It's best if you are in a roaming-only area to test this, or if you can force roaming. You'll also need to be on the stock kernel (rooted is fine) so you have the ability to update your Profile.
Let's do that now. Go to the Settings menu and tap About Phone - system updates - update profile and wait for it to complete, then tap ok.
From the home screen, tap Menu - Settings - Wireless and Networks - Roaming - Roaming Settings.
Un-check all options here (voice and data for both domestic and international)
With no boxes checked, tap the "Data" box under domestic roaming. Tap only this one, not voice.
You will get a box asking you to confirm. Click yes. This will then automatically enable voice as well.
Another pop up with a red box will ask if you really want to use data while roaming. At this point you can tell it to never ask again and click Roam.
Now you can use data while roaming where it's available!
Update:
after trying this multiple times to verify it works, occasionally the final pop-up with the red box disappears before you can read it. I was able to long press the home button to show recent apps, then tap the "Data Roaming Guard" app. Then I could tap Roam.
This is critical for me as sometimes I am in roaming areas for work and I need internet and this phone is the only access I have. Now I can use it!
Report back with any corrections or feedback. Mileage may vary.
I don't know if it's necessary to update the profile. I have that step in there because that is the sequence I used. If you try it without updating the profile, let me know. This would allow people on a custom kernel to do this too.
I spent an hour and a half with Sprint yesterday on the phone trying to resolve this. They turned me over to new reps three times (including to the international support department) each one not aware of my issue so I'd have to explain everything again.
Finally I started digging on the web and found the tip on AC. Took me 2 minutes.

DOH! Stupid Tapatalk.
Mods, please move to General. Didn't mean to start this in development.

Thanks for sharing this. I will try this out.
Sent from my PC36100 using xda premium

I have the same issues. My girlfriend has an EVO and she will have data while roaming, and I wont. Even if were right next to each other.

Thanks, this worked great for me & did not have to update profile. I am on stock rooted deodexed rom.

Worked for me! Thanks, that was very annoying!

thanks! now i can play wwf at work lol

I did this awhile back when I saw it on the AC forums. I also read this phone cannot roam on PCS networks because of a limitation in the radio so there still may be times it won't roam when other phones will.

Greetings All!
I was able to make roaming calls before; but I followed these instructions and now I can use roaming data as well. Fortunately Atlanta is a pretty good 4G metro area so I rarely need to use roaming data. Usually either 3G or 4G is available. Nonetheless it's nice to have the option.
FYI I forced roaming by using the Roam Control app and have verified that for the first time with this phone I have a nonzero "Sprint 3G Data Roaming" entry in the detailed usage screen on the Sprint website.
Many thanks!
Cheers, Henri

Ok, glad this is working for people! I know it was the biggest gripe I had about the phone by far.

[Q] Wifi Tether Issue: What the hell. Your phone takes back control over the Wi-Fi

Running 2.3.3, rooted, stock ROM. I am having this issue with MULTIPLE versions of WiFi Tether, but currently trying out 3.2 (I think) beta.
Works as expected, but after about 2 minutes or so, tethering stops, and I get the following error:
"What the hell. Your phone takes back control over the Wi-Fi interface."
It's only on screen for like 2 seconds, so I can't reproduce the entire message.
It appears that the phone turns on it's Wifi, which seems to stop wifi Tether. I am having trouble finding this exact issue on the Internet.

well i have no idea how to fix your problem but i do know that you are in the wrong forum. this should be in the Q&A.

Turn off your wifi before you use wireless tether.

Thanks for both responses. I wasn't sure which forum to post this in as I didn't know if it was an issue with the EVO, the Android version, or WiFi Tether.
I have since un-checked "Restart WiFi driver" and also checked another setting that keeps the screen from turning off.
One of those two seems to have done the trick, because WiFi Tether has been running for around 4 hours today. I'm using it with my laptop now.
Thanks again!

Forgot to mention, I also wasn't sure about whether or not wiFi was supposed to be running for this thing to work or not. Now I know!
Also, I specifically used the error message in the title because when I searched, I couldn't find anything. Now anyone else experiencing this issue should find this easy - I hope.

This helped immensely. I was getting the same error message searched and found how to fix it here. Thanks leebo!

Not sure if I mentioned this, but I also run "locale", which I set to turn WiFi on in certain locations around town. I have to remember to turn locale off when using WiFi tether, otherwise it turns on my WiFi and tether gives the error message.

There was a certain version of Wifi tether that worked great and I could tether to other devices even if my phone was connected to Wifi...it worked on my evo and evo shift, it was versions 2.2 or 2.1, I don't remember but whichever version of wifi tether is closest to that is the one that worked fine for me

What the hell! Your phone takes back control over the wifi-interface. Immediate tethe
For me the problem was that I had "Sprint Connections Optimizer" enabled. Once I unchecked that box, I could run wifi tether without any errors!
Setting Location: Settings --> More Settings --> Mobile Networks --> Connections Optimizer --> Sprint Connections Optimizer
Phone: Samsung Galaxy S3
ROM: FreeGS3 v3.0.0.0

Yes but....this is the EVO 4G and theres no such option in settings

Is anyone able to get android-wifi-tether to work on LG2?

I just rooted (teamepic cwm+root.zip) and installed the android wifi tether. Wifi tether is not working. I went to the QBKing thread in development, and see that others are having similar wifi tether problems. Does anyone have wifi tether working on an LG2 release? I am considering flashing back to a stock LF9 if sprint managed to bork the wifi tether with their latest release.
TIA.

works for me
No problems for me on LG2. What exactly is the problem?

After my laptop connects to the tether, I can't actually get out to the internet. It's like the NAT is not working. checking the IP stack on my laptop, I am getting the right ip address, gatway, etc assigned. Wifi tether shows the laptop connected. But I can't do anything.
I followed the QBKING video step by step (except using a different password for encryption). I have the Samsung Galaxy Nexus (LTE/CDMA) profile selected. I've tried some others in desperation, but none are working.
I think I'll try uninstall/reinstall of wifi tether, or maybe just use foxfi now that i am rooted.

go to settings of the wifi tether app if you havent already and set it to enable the security settings so that youll need a password on any device you enable to use your phones internet signal and that should work because i was having that problem with the wifi tether app on my evo 3d and when i enabled security protection that allowed additional devices to connect to the internet. on my galaxy s3 i havent had any problems like that cause i intiially started with this method and ive been up and running just fine and im in houston so it seems the 4g lte is up and running here cause my phone shows 4g at the top for signal and my pages load up on the phones web searches faster than when its connected to my uverse wireless modem. hope this helps you man.

Ok if you didn't already, try gnex gsm instead. Also does the tether app show any numbers moving or do they stay at 0.0. Make sure your version of the tether app is up to date as well. And disable wake lock is unchecked in settings

I had the same issues as the op. With wireless tether change profile to galaxy nexus gsm not cdma and you must use access control. Then you should PROFIT......

Has anyone had a chance to try this? Did it fix the intermittent connection problems? I am going to try it later, because wifi tether is still not working for me (LG8) using Galaxy Nexus CDMA/LTE and with the access control disabled. I am just curious to see if anyone has this working as using the GSM profile is counter-intuitive for Sprint.

I tried it and the wifi tether still doesn't work. Half the time I start it, it requests Superuser and "starts" but there is no SSID being broadcast and I don't think the wifi radio is actually turned on. Every once in a while, it will broadcast the SSID, and I can connect but the up/down data stay at 0.00kb. Other times, I can connect, and I see the up/down data slowly incrementing, but I can't actually get out to the internet (or FTP, or telnet or....).
I guess I'm just fooked until foxfi or android wifi tether for root actually release a specifically-supported SGS3 version of their apps.

My issues were i could see the ap but not fully connect or allow internet access. Make sure your using access control it will not work with out it. Also make sure you have routing fix checked and use auto not ad hoc.

*edit* I'm starting to wonder if this is an LTE-related thing. After a bit of testing, it seems like the tether works ok if I am on a 3G connection, but when I'm on LTE is when it won't work.

4G LTE hotspot data freezing itself

I've seen this happen on any rom whether it be stock or custom. WiFi tether or stock tether. I can't vouch for USB tether as I don't use it much. Basically the 4G stops working all together. My Hotspot will still be on. So what I do to fix it is go in my apn settings and refresh the connection by selecting an alternate or selecting an alternate and setting back on the same apn. Does anyone have an answer for why this happening? Is it the note 3? Or is it t-mobile? I've ran a speed test when this happens and it does not send or receive packets.

Happens on my Note 3 running Tweaked KK. I enable-disable airplane mode to get data flow back. My friend's Xperia 3 does the exact same thing on Tmo. He toggles data off and on.
Given this, might Tmo be blocking heavy data use that indicates tethering?
