[Q] 3g not working

I'm running cm7 nightly v28. For some reason the 3g does no work. The only way I can access data is to pick up some 4g. Is this a common problem? Fix?

Reflash the rom. I haven't had the issue but that could work.

Reflash the rom, and if its not in your power widget, check mobile data under wifi settings.

Sometimes mine do go right away so I turn it off and on quickly and that seems to do the trick.

Thanks for the responses. I tried reflashing but that didn't work. The turned mobile data on and off but got nothing. I even tried going in airplane mode and then out and nada. I think I might try flashing a different rom to get it working. Could it also be my PRL?

Its shouldn't affect it, but being on the latest PRL never hurts.

Make sure that its on in wireless networks...
This is my EVO, there are many like it, but this one is mine....

Mobile network is stuck on turning on -__-

Well try to reboot it real quick. And sometimes it can take it a minute or two to actually turn on.

I've rebooted several times. I've done full wipes and even to different roms. It just won't budge. :-/

I was having issues with 3G connectivity earlier. Getting lots of code 67's and data call notices. 4G was working fine so I switched on and used that. 3G is fine and back to normal now.

Did anyone come up with a concrete answer on this issue? I too have this problem and tried all the suggestions except 4g... it's not available in my area. Any help would be much appreciated, thanks.

Try flashing a sense rom and updating your profile and prl

Wi-fi broken after root.

Hey guys. I just rooted my E4GT and didn't install the kies application first. My phone is rooted and everything seems to be functioning except for the wi-fi. Whenever I go to turn on the wi-fi, it turns on, scans for a network and then the wi-fi turns off again. Am I boned? PLEASE HELP!

epic 4g wifi broke
Same for me, after Rooting with oden the wifi searches and then turns off, any help?

I'm sorry you're having the same issue. I haven't found any solutions yet. Would you please keep me in the loop if you find one? Isn't there an IRC channel where some of these guys go and help answer questions?

Something went wrong with your flash. No worries tho you just got to go back to stock and root again. Are you familiar with Titanium Backup? If you are back up all your user apps + data. Then ODIN back to factory restore. Then auto-root with this method. Lastly restore all your apps with titanium

this happened to me but i fixed it easily
forget your wifi
connect again with password and repeat it again until it works maybe 3 times

This is good advice. Do what Kogama recommends and you should be up and running. If not, hit the "HowTo's" link in my signature and follow the steps for a Hands Free Reset. Fast. Simple. Effective. Probably a good idea to do one anyway when you make major changes such as rooting or ROM hopping.

after i rebooted the wifi stopped working and i cant get it work again actually..where is this hands free reset i cant find it only the activation which I also did again

Just_s and Kogama - That method did not work for me. By time I had typed in the WPA key, the wi-fi antennae had already shut itself off.
BUT
KelvCast - your method totally worked. Is it me or does this antennae get piss poor signal strength? But I thank you VERY much for helping me. I'm all good to go. Now on to trying to figure out my write permissions on my Kindle Fire =/

for kelvcast's way you have to completely change your modem back too right? ....damn
im running a completely different rom btw...

"Hands free"is the same as "activation". Sorry that didn't work for you. The only time I had an issue with WiFi, "forgetting" the connection and then logging in fresh was what worked for me. Any other data/ connection issues I've had have been resolved via the hands free reset.
As far as your other question, you don't need to change modems, but it won't hurt if you do.

I have the same problem as OP. Rooted using the Zerg exploit, running stock ROM. When you turn the Wifi on, it only gives you like 5-10s before it turns itself back off, also the MAC address field shows unavailable.
Assuming it's an issue with the root process. The odd thing is mine worked fine for over a week, and just randomly died today while trying to connect to wifi at school. Was going to reflash stock kernel with ODIN, and see if it effects it at all.

How do you forget your wifi?

Hated to do it, but had to flash stock ROM, just the kernel didn't do it.

I was having the same problems... flashing rogue kernel 1.3 fixed it perfectly for me. Hope it helps

My WiFi is working fine with the method I used. Rooted phone and everything.
Not sure if I will be keeping Sprint anyway.
Did a speed test on my moms old LG Verizon phone running at 600mhz. Compared it to my Sprint SGSII running at 1.2ghz dual core. On the LG, I get a little more that 1/2 a meg per second (which is decent in this area) as compared to .01 - .1 meg per second on my SGSII. So there is a BIG difference in speed. I know its not the phone, but the network. Going to do my due diligence and keep the sprint phone for at least another day. But if it goes as it is now, I will be going to a Verizon store Sunday and switching carriers again. Sprint doesnt seem to be better that TMO. Sunday is my 3rd day so if I return everything to sprint, I get a full refund.

Yeah it's hit or miss. In my neighborhood, my buddies with Verizon pull down 1/3-1/2 more bandwidth, but my phone works in any basement in the area and theirs doesn't, go figure. In the mid-town/downtown areas both carriers perform about the same around here (Omaha, NE).
Now if you're talking WiMax and LTE thats a different story altogether.
As for the Thread topic: I think I know what broke mine- I restored a bunch of apps using Appextractor, and think restoring the "Settings.apk" in the system section toasted it. I tried flashing a few different kernels to no avail (Did not try the rogue kernel, however).

Lost WiFi after rooting Epic 4G Touch
I have been fighting this problem for a week now, finally I installed clockwork mod following a youtube video titled (How to Install Clockworkmod on the Samsung Epic 4G Touch - Latest) sorry cant post link new user arent allowed to post links. my phone was already rooted. I now have my WiFi Back.
Hope This Helps

I have tried every method I have been able to find.....Still no wifi. I rooted via this guide (http://forum.xda-developers.com/showthread.php?t=1265429). After following that guide my wifi did not work. Just scans and then turns off. Does not even see any networks. I flashed the stock kernal. Still no wifi. I don't know what else to do. I am going to try a factory restore. If that doesn't work I might need to send my phone in.....This blows.

[Q] Evo 4G on Boost Mobile Stale Data Connection (Error 104)

My data works. I'm getting 3G speeds (approx 2 mbps). There are NO other errors on this phone except the random Error 104 and only sometimes Error 67. I've updated my PRL to the 11115 version. I can leave my phone on and not touch it, the data connection randomly kicks out, goes stale, the sending arrow is active, but nothing responds. I have to cycle my data connection off then back on, and that usually fixes it.
It does this A LOT. So much so, I put a Mobile Data on/off widget on my home screen. The internet works just great when it works, how can I get the connection from basically stalling out ALL the time?
If you've had this issue, or are having this issue, please respond.
The donor phone was a w385 (which is a 1x phone I know, but again, I'm getting 3G speeds, guaranteed - when it works right, I can stream HD Youtube videos with no problem at all). How can I get this connection to go up and STAY working??
I'm pulling my hair out over this one...

Mine is doing the exact same thing. Started this morning, has been perfect for the month or so I have had it on boost. Its been driving me crazy all day.

Mine's been doing it since I got it. I was primarily in a wifi area, now I'm strictly on 3G and I can't stand it. I'm so desperate for a fix, especially if it's something I'm doing wrong...

Out of curiosity... have you changed anything, like a kernel or ROM? If it's a kernel, what did you change it to? Trying to see if we have any similarities in our setup and work backwards from there...

I haven't changed anything at all. Im running stock rom with nothing but factory updates, have done nothing to this phone except root it before it was flashed. Just went to sleep with it working fine and woke up next morning to this. I haven't been getting the error code today as much but still having to turn data off then back on a lot. im about ready to throw this phone out the window and go sign a contact lol

I'm having the same problem. I just flashed my phone over to boost mobile a few days ago and I had a hard time getting 3g data to work. I was getting 1x data only. So I got the different passwords that I needed and 3g started working. But for some reason, after about 5 min or so, the data would just become stale and nothing would work (web pages, twitter, etc) even tho the data icon and arrows were still present. Its been happening ever since I flashed. I'm not sure what's causing it but if anyone has any ideas I would greatly appreciate a response.

It's your location. I moved from Haslet, TX down to Austin, TX, and I haven't had a single problem in Austin. Just to confirm, I went back up to Haslet, BOOM instantly started happening.
It's an error with the towers in particular locations. I confirmed it by calling up Sprint, and asking them to check in Haslet's zipcode for any issues, and they did confirm there are issues in that area.
I was sooooo ready to dropkick this phone. Sorry for the unfortunate news, but with Sprint's little network upgrade, it's causing these issues.

Thanks for the update man. I was about to go crazy!! Well hopefully they can get this issue worked out pretty soon here because this is getting ridiculous

Yeah I had to update this to let those with the issue know. I couldn't stand it!

Well I'm in Atlanta and mine quite giving error codes but internet is slow as hell right now. it does it at my house, job, our wherever I'm at. 40 miles away and still does it.

That's cause you're still in the same market.

Won't Connect to 4G

So everything was fine on my Evo (running one of decks roms with a ICS theme) until the screen went out friday night. Saturday I took it in and it was repaired in about 2 hours (very impressed). In between I activated an old back up phone to get me by. When I picked up my Evo the tech had reactivated it and it was ready to go. But when I got to work I had no data. No internet service at all. Calls and Texts were fine, but nothing else. I made sure mobile data was checked, (couldn't update PRL cause of the AOSP rom), but I did a battery pull, rebooted, then I decided to nandroid back to a previous sense rom. Once I booted up still nothing. after about 2 hours all of a sudden I was getting emails, and voxer messages....I had data back!!! But when I tried 4G nothing happened (stays on obtaining IP). Hoping a newer stock based rom would help I flashed the new swag ON rom. Loving the rom...everything is great, but still no 4g. My last resort is to unroot and go back to sprint. I downloaded the wimaxx checker and it says I have my RSA keys so I know those are there. I'm sorry if this is a bit long winded, but I thought being as detailed as possible would help. Any suggestions would be great. The members here have helped me through lots of trouble shooting in the past.
Should also be noted that I attempted PRL update again with no luck, and I live in San Antonio which is a solid 4g area for me.

Good thinking with Wimax Checker - That's usually the first line of defense.
It sounds like because you cannot update PRL or Data Profile that there may have been an issue in the reactivation by the tech at the Sprint store. With that said, I know I'm in the Philadelphia region with good 4G but occasionally there will be a day or so of PRL/Profile update "outages" where I cannot update. I usually will verify with a family member's phone (also on Sprint). Perhaps try having someone you know in the area with Sprint and an android phone try a profile and/or PRL update to make sure it's not just the system being unresponsive.

Ok I will try that tonight and reply back. I had my g/f's evo running decks rom try her 4g and it worked perfectly so I know its my phone. I'll see if she can update. Either way is there some sort of combo pack I can flash for profile and prl??? I'm not too sure how that would work.

Here is the latest Radios-Wimax-PRI-NV Combo pack Click HERE

Ok I flashed an older Wimaxx since the one I had was up to date(did a check in TE). Once flashed and booted up still no 4g. Is it possible that this could be a hardware issue since everything else works? Like the actual antenna is busted? Just hard for me to think that since it was working fine before my screen went out. I always have 4g service at home and work. And my g/f's is working fine she has the evo and she has sprint.

*Unbelievably long Data Loading times. It takes 5 minutes to get my speedtest Ping.*

Hey. I flashed task's AOKP 8/26 rom and started experiencing strange loading times when on the internet. I just flashed Paranoid Android's rom today and I'm having the same result. SpeedTest app says I only have 40-100ms ping, but takes 5 minutes for it to actually find that data.
It says on the top that I am in '4G'
I don't think it's a throttling issue, I get 20 Mb/s down after speed test finishes
My ping is 95ms, but it takes about 4 or 5 minutes to finish the ping process
I am on the LTE settings that came with my ROM and they are the same as task's as well.
Upload speed is around .84, 4.0, 3.0 MB/s respectively
All Web-browsing, SpeedTest app, Google Music, and Play Store take forever to initially load
Any ideas on what it could be or what I could try? I have tried flashing the latest modem, same result as I had on task's and Paranoid's rom.

I was just about to post a thread on this same issue. Its driving me nuts!
I fist noticed the issue when I flashed from CM9 to CM10. Today I tried task's jb aokp ROM. Same issue. So I flashed cm9, it didn't get any better. Next I'm gonna try Odin back to stock. What's really odd to me is WiFi is unaffected. Only when on 3g/4g.
I've checked my imei, and its still correct. I've tried all 3 available modems.
I'm not to sure what else to try. Hopefully we can come up with a solution.

Have you all with these issues posted these with the ROMS thread and brainstorm with other users of the ROM? You could try that. I personally heard great things about Task's ROMS and paranoids. To make sure, have you all tried wiping EVERYTHING in recovery and i mean wipe data, cache, dalvik cache, before flashing the ROM? You all might have to do that and then report back.
Sent from my SGSIII with the XDA Premium App

wow, wasn't expecting people with the same issue lol. I checked my Data usage also. Only at 4.1 out of 5 Gigs.
And yes Bruce, thanks for the suggestion. I wipe everything possible before every flash and always have. To the point where I even wipe things twice without realizing. (Cache, Dalvik, storage, system, cache, etc etc, even the eemc).

Tried basic apn settings as well as the 'phone' hdspa+ settings. same issue. reflashed over and over again, problem persists.

AT&T is beginning to work on a major LTE rollout from what I understand. I suspect this is a side effect of preparation. It would be interesting to see what going back to stock does.

That's what I thought too but flashing back to stock with Odin seemed to fix it. Problem started after installing 9-02 cm10.

how are you guys doing on this issue?
i flashed back to stock as well and my problems were fixed.
...really want a modded rom though. think it's a cm10 issue?

Same here. Flashed back yo stock because my h+ was behaving like 2g...seems to have helped quite a bit.
Sent from my SAMSUNG-SGH-I747 using xda app-developers app

I see similar behavior while stock, have managed to not root and flash yet. Although, in my case it isn't actually 5 minutes, but there's definitely latency, it just doesn't normally show up in the ping time.
A friend with his also at stock (never rooted nor flashed) mentioned he was seeing this as well...

I too have been getting problems. I thought initially that it was due to Task's ROM, but then i went back to CM10. And im still getting these issues. My girlfriend is running AOKP on her SG3 on Tmobile, and she's not getting data issues. Im thinking its a problem with AT&T.
I was about to go back to stock and see how that goes. But since 78c10 says he sees no improvement, then....idk wats going on. =(

stock not rooted. same here.. takes forever for things to load. the connection seems to stall for a bit then kick back in.. has to be something with att not the phone or roms etc..

Having the same issue. Just got done wiping everything and formatting my SD. Still VERY slow. Was going to try stock next.
On task's AOKP.
If anyone finds a solution please post.

Everyone here should post their issues and location because they've been rolling out LTE here in Philadelphia & it caused a lot of the same issues for me & others. It may be completely unrelated but it's a strange coincidence considering how much work they're doing on LTE right now.
Sent from my SGS3 using Apple's patents

It seems to be hit and miss here I just keep rebooting and then I'll get lucky one time and it will have a snappy data connection lol and its universal so I think its an ATT thing. I have been back and forth between stock, ktoonsez, and cm10 today and it isn't bias. I am in fort Irwin, CA right now and am straddling H and H+ but with solid bars... and sometimes I can't even load xda it will take like 5 minutes but what in really find strange is that I can stream Netflix...

A few of us in the Houston area are reporting data connection problems (reported in AOKP thread). Someone stated that Houston has been having problems with their LTE network... This would make sense, as i was at a friends house in the heights on Sunday, and we had full bars LTE and neither of us could connect or stream anything data wise. Now, while I'm on latest AOKP, he has a skyrocket, and is running stock ICS... So it has to be the network.
I live in the Woodlands, and ive been having the same issues up here too (just speed tested, & topped out at 9 mb/s - i remember getting upwards of 40 mb/s when I first got this phone). Really starting to piss me off.
Anyone in the Houston area herd anything from AT&T yet?

Just to let everyone know my issue was solved by going back to a 8/25 AOKP flash and whola, perfect again.
I would have to say that its related to the current builds. At least on mine.
