I have found one thing to work to fix wifi cutting in and out. You will need to obtain your MSL in order to do this though.
Procedure:
1. Go to dialer
2. Enter ##786# (##rtn#)
3. hit reset
4. let the phone do its thing, works for rooted (at least on mean rom) and non-rooted
5. once the phone boots back up, skip through the initial setup steps DO NOT LET THE PHONE ACTIVATE OTA
6. go to settings and enable wifi and disable mobile network
7. connect phone to wifi
8. go to settings and activated device.
9. device will reset
10. done!
If you are in a non-LTE market, make sure the network settings are set for CDMA only and not CDMA/LTE

I am not 100% sure, just what I found out from my tech at my store. He said it has worked for most evos, but not all. I believe it has something to do with how it activates over wifi instead of ota

You're missing step 3.5 as this requires your phones MSL code. I posted this in another thread about data connection issues. take a look see

This will reset the phone to factory so if you don't want to lose you data nadroid backup first. This clears amoung a few settings the PRI and PRL, factory resets and looks for firmware updates. Be cautious.

The phone cannot program over wifi. It has to come over sprints network through the OMA-DM tool. All this is doing is resorting the back to factory defaults.

WiFi cutting out might actually be just accidental pressing on the wifi antenna contacts. The fix for this is usually opening up the phone, unscrewing the plastic shroud beneath the removable plastic cover, and then gently using a small flathead screwdriver to bring it back up, and then putting some sort of cardboard or something similar to keep it propped up.
THIS IS VERY DANGEROUS! The antenna connectors are very weak and easily snapped. Don't do this more than once, as you will probably break the contacts through stress.

I know for a fact this is not my issue. The original post fixed my issue and I know it has fixed various other phones customers have brought to me.. not all but most of them. I have had a case on my phone since day one and do not take the back off, except to initially put my sd card in.

I currently use cm10 as my dd. Flashed back to Sense (meanrom) to do a ##3282# > data profile > restore in an attempt to fix some minor 3G issues. After restoring and rebooting, the hands free activation never started. Tried a manual profile and prl update with little luck. Currently, I have no 3G signal. I was able to get 3G back very temporarily after doing a ##72786# >menu > reset; however, it would only work in LTE/CDMA mode and would usually drop-off very quickly. Tried reverting back to AOSP and data was still gone. Has anyone experienced this? Is there something else that Sprint has to do on their end?
I had the same problem no 3g for a week then I went to a repair sprint center, the guy said it was the phone wish I had uprooted before going in. He did all the firmware update and nothing, knew it was the phone cauz i did the ##786# and was not doing anything because I had no data. Anyway sprint gave me a new one for 35$.which suck because came with the new hboot 1.15.

Here are a couple more observations. On a sense ROM, I can get 3G as long as I keep it on LTE/CDMA and not CDMA only. Once i switch it, it immediately disconnects. When I switch over to CM10 I get no 3G at all regardless if I am using LTE/CDMA/EvDo or CDMA/EvDo auto. Also, when I am connected to my airave I am unable to get any type of 3G regardless of the mode that I am on. Is there a setting within "data profile" that is preventing me from connecting to "cdma only"?
Tried two additional things with no success - 1. Switched to cdma only and tried updating profile. 2. ##72786# to reset data.
There shouldn't be an issue with cmx other then having to switch to CDMA/auto. Try switching to CDMA auto and immediately reboot the phone and let it just sit for about 5-10 minutes it sounds bad but its not these are nighties and it will be fixed soon enough
Is the active profile set on 1? I had the same problem, and I was able to get data back by doing a profile update over WiFi..

you sir fixed my issue...thank you!!!! Hit a roadblock with a "vDM stopped unexpectedly" error which prevented me from updating profile. Flashed a nandroid, changed data profile to 1, updated profile over wifi and it worked. Can switch between cdma and lte without a problem. Flashed CMX again and 3G connected right away. Thanks again!
I have AT&T Note, stock ICS, rooted. I have been having problem with inconsistent data connection, even though I have good AT&T signal. For example:
1). Signal is 4-5 bars
2). I CAN make phone call
3). Open browser, Gmail, etc - the "4G" icon shows it's trying to connect, but nothing happened. All the application will timed out.
I tried this in different locations (home, work, airport, etc.) and same problem.
I didn't change the APN or install custom ROM. I am trying to figure out if this is just my phone (bad radio, etc.) or a widespread, known problem for AT&T stock ICS.
Please chime in if you have the same problem.
Did you try powering down.... Then a battery pull..... Battery back in.... Reboot..... Turn off wifi... Make sure data is turned on..
Write back.... Good luck

I did try those, specifically:
1). Power down and battery pull out
2). Airplane Mode
3). Disable WiFi and BT - leave only cellular signal
The only thing I have not done is hard reset.. But before doing that (it'll take me a long time to re-configure everything), I want to get feedbacks from other first..
BTW, the ONLY thing I can think off that MAY mess up with the connection is Avast! Anti-Virus. It has a built-in firewall (root required) to prevent select apps from accessing the Internet. However, with WiFi, I have no data connection issue even with Avast! firewall running.
Un install avast and see if that helps.

I did, same thing... Can make voice call but no data. Even when I rebooted and pulled the battery. About 10 minutes later.. data magically comes back!
Does anyone else have this problem? If yes, please chime in..
I am thinking of doing hard reset. Will this make my Note lose root?

I can't reset the default APN...check I can't even edit it. I think AT&T blocked it.
Did you just get the note or did this just start happening? If you just got the phone did you buy it new or used?

you are right.. you cannot edit and change the default ATT APN....
BUT!!!
You can create a new one.... and choose the new one over the default...
you are allowed more than one APN...
Modem .....and APN settings are the most likely causes.
APN settings first of course.....g
Thanks for the suggestions.
The original APN cannot be edited, so I created a new APN and select that. When I press the "back" button and go back to the list of APN, the phone AUTOMATICALLY selected the original APN, not mine.
I selected that again, press back button and waited for 5 minutes (in case the phone trying to update whatever it needs with the new APN). Went back to the list of APN and the original APN was selected again! (???).
So I think something went awry with my phone (I already uninstalled pretty much everything), and just for a test, installed a new ROM (Padawan v7). So far so good, but I haven't done extensive testing (at home, not traveling) yet.

I am new to root and ROMs so perhaps I overlooked a setting.
I just rooted my phone and flashed CM 10.2 a few days ago and I cannot get 4G anymore. I can only get 3G. I have tried a few fixes like dialing *#*#4636#*#* and adjusting the APN settings but nothing worked. I have the LTE button ON and I am wondering if I am still getting 4G because I have LTE on and it's just showing 3G. But I don't think that's the case.
Any help or tips would be greatly appreciated!

reflash stock rom. make sure you have 4g. flash the vram3c radio then flash cm10.2 rom. you should have no problems with 4g after that.
I will try that. Thanks!

I tried flashing the radio and CM again and sometimes 4G comes up for a few minutes and goes back to 1X. This happens where I have gotten 4G before. Maybe the radio isn't as strong?

My personal experience, living in a fringe signal area, is that AOSP roms just don't have as strong a signal as TW roms (it presumably has to do with how the RIL had to be hacked/reverse-engineered to work for AOSP). I would prefer running AOSP, but unfortunately in my experience on my S3 and Note2, where I am located on the fringe of full 4G coverage areas, I have the same issues as you: on TW, full, fast, 4G; on AOSP, very obviously slow 3G or 1X.
Edit to say I've only tried 4.2.2 ROMs, haven't tried the 4.3 ones yet, so if I'm handing out wrong/outdated info, I'd love to be corrected.
I am now running a stock 4.1.2 ROM and still cannot get 4G. I now for some reason can't even dial *#*#4636#*#*. When I try it just says "Welcome to Verizon Wireless, this call cannot be completed as dialed." Anyway to get that number to work so I can check my networks again?

Try going into settings and factory reset phone now. If that doesnt work, reboot into stock recovery and factory reset from there and reboot. That seems to restore signal for those of us that got stuck in roaming mode from the Carbon thread. Might help your problem too
So I decided to re-flash CyanogenMod 10.1, adjusted the APN settings again, and I have 2 bars of 4G right now. Usually 4G will flash a couple times and change to 3G, but it is staying 4G, so hopefully it stays that way!
Well it stayed 4G for a bit until I turned WiFi on. The moment I turned it on, my 4G went to 3G. I turned WiFi off and I still have 3G. Anyone know what would cause this?
EDIT: My network type shows eHRPD with 3G, where as when I had 4G (before I turned my WiFi on) it showed LTE. If this helps any.

Where do you live, i know the mid Circle drive all the way over across platted to the airport are just dead zones. I lived on Verde drive and rarely had good signal, then when i moved up circle behind the bowling alley i never had a good signal. Just something about the antennae in that area. T-mo is a complete bust in that area. But i'm sure you probably all the way over on the Nevada side completely making what i said irrelevant.

Do a search on towers in your areas. If I remember correctly the closest tower to you in right by the interstate by the new (now not so new) MCD's in Security. That tower had alot of problems in the area past the Olympics complex all the way back to Peterson because of the radio towers for the Jets. I have been gone for almost 3 yrs so don't take what i say as truth tho. Just how it was when i was there.

2)Once installed find and open Build Prop Editor
3)Hit the menu button and select Edit
4)Scroll to the bottom of screen and add the following lines
Code:
ril.sales_code=LOL
ro.csc.sales_code=LOL
5)Hit the save button at the top right hand corner of the screen(looks like a disk)
6)Once this is done saving restart the phone
7)After restarting go to Settings>More Settings>Mobile Networks>Access Point Names>Menu Button>+ New APN
8)Add desired carriers APN info, when finished hit menu button and save
9)Power down and change to your desired SIM card if you hadn't already done so
10)Power back on and go to Settings>More Settings>Mobile Networks> Access Point Names (if done properly you should see the APN data you entered for your respective carrier).
11)Select the respective APN listing and then you should have working data

I tried this but having the same problem, so I decided to save the APN each time I edited an item, and every time I would change the MNC and save, it would not be on my APN list, and it would be blank again.
Bump... also having this issue. Trying CM 10.2 for the first time since August. It had Bluetooth issues back then, so I've been running Bean's ROM until yesterday. Can't get 4G serivce in what is absolutely a saturated 4G area...
Was able to fix the issue by wiping the phone completely (including internal storage!), installing Bean's ROM, doing a factory reset, then coming back.
FWIW I always wipe internal storage when going back and forth between 4.1 and 4.2+ roms, seems to alleviate any SD card issues that can arise from the changes to filesystem in 4.2.
I do not have any data or voice connection. My phone is just a digital phone book at the moment. Early Monday morning around 2am the phone was working fine I had voice and data. Around 4am I look at my phone and there is an X above the signal bars.
So far I have tried dialer codes- the phone seems it does not recognize them, nothing happens (the view and edit modes do not come up)
soft reset, hard reset
Restoring a back up-no luck
Run the newest 4.3 RUU-no luck had data for a few seconds then gone again
Tired running ViperRUU-still no luck
I also tried to call Sprint but as usual they were no help
My phone is Locked but S-off
Hboot 2.10
Radio 1.13.11.1105

Try ##72786#, then select reset from the menu once it pops up. If that doesn't work, do ##3282# and hit reset. You'll need your MSL code to do this. You can call Sprint and get it or use the free MSL reader app from the Play store. You have to be on a Sense ROM to use dialer codes.
Edit: Saw where you tried the dialer codes already. You'll need a ROM with EPST support to use them. Hit up my Q&A thread for the Sense 5.5 ROM-one of the FAQ's in the second post explains how to do this.

I thought Viper 4.0 support EPST? I will try to restore my Sense 5.5 back up and try again. But when I try to use the dialer codes they don't work. I can enter the code but it seems like the dialer freezes and it doesn't take the code. I have to hit the home button to get out of the frozen dialer.

1. Turn on the airplane
2. Go into settings and into the auto setup thingy. I forget what exactly it's called in that ROM, but it's almost always right above the software updates section. After it tries for a few seconds, hit the home button.
3. Now go to apps and under "all", find "phone". Clear it's cache/data
4. Right afterwards, and with airplane still on, reboot your phone.
This probably won't fix your problem, but should reset the godonlyknowswhat so that ##SCRTN# & ##DATA# are again recognized by your phone (assuming you're on a sense-based ROM).
I had this exact same problem and that fixed it (well the dialer problems anyway). Not 100% sure why either.

Thanks, That got the dialer codes working, not all the time but few times so I can enter the codes. Now It will not do the hands free connection. 1012 is the error code coming up. I think I'm going to bite the bullet and bring it into a sprint repair store, and hopefully its something easy to fix
Well the damn Sprint repair store was closed. But I was able to finally fix my phone. I used the ##786# dialer code and did a factory reset. Thank you everyone for the help.
I have an LG V30 with Sprint. Last week I noticed my phone wouldn't connect to LTE/4G network even in places where I know there is good service and other Sprint phones around me are fine. So right now it only connects to 3G and even then is mostly keeps going into roaming and won't go back to 3G until I toggle mobile connection on/off. I've tried just about everything I can do. Turned the phone on/off. Checked for updates. Toggled mobile network connection settings. Network settings reset. I even factory reset it and the problem persists. What very little I could find mention of this problem online mentions messing with the APN settings, but I'm not able to do that. For what it's worth the phone still connects to wifi just fine.
Any advice or help would be appreciated because I'm really lost here and it's becoming a real problem for my phone to barely connect to anything unless I'm on wifi.

If you're on stock, reset your SCRTN
Open dialer and type in the following code

It will ask you if you're sure you want to reset, click on yes
The phone will restart and it will go through the activating process and you SHOULD have LTE now.

Does this process wipe your phone to factory settings?

Nope, it just resets your network settings only. Your pictures, apps, music, and other things are left untouched.

SCRTN is a wonderful thing, solved problems for me many times when I was on various Sprint MVNOs.
But it only works with CDMA networks and phones (Sprint & Verizon).
For stubborn network problems on other non-CDMA models and networks I found the engineering/service menu factory reset to be a life saver. In particular did it solve a lack of LTE connection after a "partial" T-Mobile SIM unlock. To be clear, it loses the SIM unlock, which allowed me to unlock anew (and fully this time). Just be aware of that.
1) Backup everything, as the phone will be wiped. If yours is a network unlocked carrier model, make sure you have an unlock code (or unlock approval if T-Mobile).
2) Remove your Google account to disable Android Device Reset Protection.
3) Dial *#546368#*932# (replace 932 with your model number). This should open the service menu. From there SVC Menu - Factory Reset (R&D Only).
This takes quite a bit longer than normal Factory Reset. Your phone is now TRULY back to factory state.
While I haven't experienced any problems after doing this, I cannot guarantee that it is risk free or that there are no side effects that I just haven't detected.
So I would ONLY do this as a last resort.
