So I just picked up a Thunderbolt from a local Verizon corporate store. The sales rep told me NOT to use WiFi on my phone because of an issue all Thunderbolts are having. She said once connected to WiFi, it won't be able to switch back to 3G unless you perform a factory reset. It sounds like a load of crap to me, but I'd rather play it safe. Can anyone confirm or deny this out there? Thanks in advance!

I connect to WiFi all the time. I did have one phone that wouldn't connect to 3G. They ordered me a replacement. The next day it started working again but I already had the replacement so its on its way back to Verizon.
So..yes, load of crap.

sounds like someone heard some dumb rumor, and instead of verifying it, assumed it true.
Mine has no problem going back and forth. I don't use 4G here.

I do believe i'm having this problem. I came looking for a reason as to why I cant seem to get 3g anymore. I go in and out of my wifi at home throughout the day and lately, for the past 3 days, i can't seem to get any data signal. I have seen 1x occasionally and i have also tried flashing a new rom and kernel to no avail.
EDIT: The factory data reset also didn't work. I haven't done anything to the phone other than rooting it and installing das bamf
EDIT 2: The instructions in http://forum.xda-developers.com/showthread.php?t=1025259 have worked perfectly to restore my data connection.
I have tried multiple radios and roms but with no success. It's always the same issue. I can get 3G working fine. But once I turn on 4G, if I look in the radio settings, I can see it constantly switching between LTE and Unknown for the network type.
I've tried running fix permissions, on multiple radio/roms. What else can I do? I really need some help. If I can't find a solution I'm going to try and have the store replace it for me after unrooting.
This is my 3rd day of this issue. Could I have changed a setting somewhere unkowingly? What should I check and what should I troubleshoot?
Any help would be MUCH MUCH MUCH appreciated! Thanks in advance!
And before someone says search, I have scoured everywhere I could think of and in as many different ways as I can. I really need some expert help here!
Fixed!
I had a moment of clarity and remembered when I started having issues. Flashed cm7 rc.6 and checked my network settings. At some point I think I turned off National Roaming. Which I think was On before I was having issues.
Flipped the switch and restarted and viola! 4g is back and stable.
I was wrong! It didn't fix anything. I flashed to bamf 1.7 and the 4g issue continues. Help!
This may or may not help. I was having 4G issues as well. I was only getting 1X or 3G for days with an intermittent flash of 4G. I took another person's advice on here and I removed my Sim, booted without the Sim, and then put it back in. I have been in 4G since I did this.
The LTE radio app is helpful for fixing 4g issues. 1st switch to 3g than once you have it than change setting to LTE. That has worked for me in the past. Also make sure batt cover is on.

Thanks for all the input everyone! After 2 hours on the phone with Tier 3 support, flashing my phone, removing sim, privisioning my phone, resetting the network switches in my area and syncing multiple things on their end.... Nothing changed. They said is was my device and I'll have a new TB and sin on Tuesday! Lol
Thanks again!

Ever since around the 4th my 4g has been acting up like crazy. I live in Hollywood so I don't think it's a verizon issue. Has anyone else been having problems? I'm thinking maybe it was from an app update with a glitch in it? My phone is totally stock but I have around 400 apps (I know, too many, I can't help it...) I've gone through all of the app permissions looking for an app that can change my network connections but no luck so far. I know this is kind of a shot in the dark but if anyone else had this happen and figured it out that would be great. I'm open to suggestions.

The My Verizon App was recently updated (and removed the homescreen widget, so I didn't update mine), so that might have something to do with the problem.
Does 3G work fine?
I have been having this same problem, so is a friend on another device. When we switch to 3g, 4g never returns unless airplane mode is cycled.
My my verizon app is up to date but I still have the data widget. I haven't updated the "location agent" one though. I'm not sure about the 3g working...the 4g symbol just comes and goes so fast I don't think the phone has time to switch onto 3g. It doesn't happen 24/7 but when it does it's like a non stop cycle of on and off (like an app struggling to do something)..

So my daughter just recorded a 10 min video on its a small world. Next time I check my phone I have no 3 or 4 g just bars. I don't think anything of it until I'm elsewhere and my wife has 4g and I don't. I cycle my 4g widgetsoid and get service. Screen off and on and no Vs again. Airplane mode, same problem. Finally I put it in airplane, powered it off and did a battery pull. It's fine now.
I've tried turning the phone off, fully restarting it, pulling the battery, and cycling through airplane mode but I haven't tried pulling the battery off after powering down while in airplane mode though (that was a mouthful). Maybe that's the magic combination... I'll give it a shot and see what happens, thanks. I'll post if it helps out or not.

Had the same issue sporadically. Only app I've added since then is Firefox beta but seriously doubt that is to blame.
Actually had this issue this morning for a bit, then resolved on its own.
I have been having the issue of my 4g randomly dropping, 3g not kicking on (just signal bars), and the 4g coming back when it feels like it.
I did a battery pull, cycling the 4g, airplane mode, etc. and still having the same issue.
This started around Verizon's useless upgrade.

So far so good since I did a battery pull and let my phone fully boot while in airplane mode... Only time will tell..

I haven't had 4g since I rooted....so I am a little worried...
I also have had the worst 4g service the past week or so. I have a htc rezound and live in the suburbs of Detroit, MI. I have tried everything under the sun but cannot get it working. This is obviously a Verizon issue, because it started happening out of nowhere. I didn't download any nee apps or change any system settings. I don't understand why this is happening. I do not want a refurbed phone so I will not send mine in for a replacement. I'm sure that wouldn't even fix the issue. Verizon needs to get to work and figure this out.

My 4G is fine and I'm rooted and running a custom ROM (Ineffabilis 1.4).
Have you checked if 4G is enabled in your settings?
(Search for 4G toggle in the Play Store)
Some people reported that their phone disabled 4G in the settings for no reason.
Everything was fine for a couple days then all of a sudden it started acting up again...I have a feeling it's the new draw something free app...maybe..

Lol apps do NOT cause data to cease or "hang". It appears to be Verizon as I have been having 4g issues on stock gb and ics.

Same issues here (multiple ROMs). 4G has been sporadic or non-responsive and 3G is about as bad. Started a couple weeks ago. I have tried hard resets, ROMs, firmware updates, etc and nothing.
Good to see I'm not the only one.
Any other Verizon devices that can confirm this?

Ok, so I've had the issue that the OP is talking about since I got the phone like 5 days ago. Since I wasn't rooted (and still aren't) I decided to call Verizon about the issue. I've talked to multiple Verizon techs and after they had me do basic steps, like checking wireless networks settings. Nothing they told me I hadn't tried myself already prior to calling them. I even got a replacement BRAND NEW rezound and sim card and am still having the same issue. I have decided to try and figure it out myself and have been running various logcats to try and narrow the issue down. Problem is I don't really know how to read these logs too well. If there was someone who has more knowledge in reading logcat logs id be happy to upload or send them to you if you think you can help. Any help in resolving this issue would be awesome as Verizon seems to be unaware of the issue up until now and I would like to resolve it before I root. I'm going to give them a call tonight and explain some of my findings to see if they can give anymore input or get me to a higher lvl tech.

According to my findings, it very well could be. I'm thinking it may have something to do with vznavigator. But don't quote me on that as from what I said before, I don't know how to read logcats too well.

Yeah I'm still having issues. There must be something going on with verizon? I haven't dealt with logging yet but I'll look into it and see what happens.

For the past 4 days or so my phone has been able to "connect" to the 4G network but I cannot receive data over it. However when I switch the phone to 3G only data works flawlessly. Calls and SMS works fine but the browser and any apps that use data say no connection. The connection icon is grey instead of blue.
I've been running CM7.1 on the thunderbolt just fine for months but I decided to use another ROM just to be sure. Put thundershed 1.6 on today and for a while 4G worked but it died again. was using radios 1.48.00.0906w_1, 0.01.78.0906w_1. Thought it may be a problem with those so I flashed the just-released 1.49.00.0406w_1, 0.01.79.0331w_1. No change.
I've gone through all the other troubleshooting steps too, hard/soft reset, battery pull. reseat SIM card, toggle airplane mode, switch off the LTE radio, etc. Called verizon and they confirmed I have a recent PRL.
Anybody have thoughts as to how I can fix this?
i've been getting in and out data connection with the newest radio on my thunderbolt atm...i'm starting to wonder if its the phone itself
I don't think its anything we can fix ourselves. So many people are having problems similar to this that it must be verizon. I had exactly the same problem you are talking about and I can get it to straighten out by turning airplane mode and taking it back out.

I really hope it is verizon and not my phone, but I've talked to them probably 3 times in the past 2 days and no one has even hinted that they are having network problems.
So right now I guess I just have to wait it out. Man I hate streaming music over 3g...

Update on the situation - My 4G data is back after about a week.
Looks like I was temp banned from Verizons 4G for using too much of my unlimited plan. Can anyone confirm this happening to other people?
Thats what I suspect at least, it could be a coincidence and their 4G tower in my area was broken for almost exactly a week.

Ever since about May when Verizon pushed an update out, my WiFi functionality has gone completely down the ****ter. I will describe my symptoms to you.
If I connect to a known WiFi network, I can connect to it if I am in the same room. However, the moment I step into a different room I loose my WiFi icon on the status bar and if you go into your WiFi settings it will say "Authentication error". When you tap it to reconnect to it, sometimes it will bring up the password entry page and presume to say "Authentication error", sometimes it will do nothing.
The moment you walk back into the same room again, though, you have to open the WiFi settings but once you do it will connect back and say so at the bottom of the screen.
I have read that lots of people experience this only after a certain Verizon update, like me. I have gone as far as to load the original factory .tar file that Verizon first used, before any OTA updates applied.
There are numerous accounts of this problem relating to my specific model, multiple responses from Verizon reps on the Verizon forums, Samsung responses on there forums, and I have still not seen any kind of actual fix.
Is there some sort of remedy for this? I want to sell this phone soon, but not in this condition.

I also have a weird issue. I can't connect to any 2.4GHz networks at all. I have no problems connecting to 5GHz networks though.

I just noticed a few weeks ago when I tried connecting to someone's wifi and it just wouldn't. I did notice when I first got my phone that the speed on my 2.4GHz network on the phone was very slow, so I just used my 5GHz network. But now it won't even connect to any 2.4GHz networks at all. It sees the networks but just won't connect. It is a verizon refurbished so probably gonna have to unroot, return to stock, call and get another refurbished unit. Just didn't want to go through the hassle of there was a fix for it.

It's a known issue with the Note 2. I restored my phone back to stock, unrooted, did a factory reset, and still had the issue. So I called verizon and they said it's a known issue that lots of people have called in about. They are sending me a replacement, which I should receive tomorrow. I'd recommend doing the same.
I had to do the same just yesterday, so my replacement should get here in two days.
