[Q] Data and Phone network connectivity problem

My Verizon GN is having difficulty connecting to my phone and data networks. It all started on the day of the outage this week. I assumed it would all fix itself, but it has not. I've snooped around the board quite a bit and it seems all other users have had their connections restored.
I first noticed the problem on Thursday morning. My data status in notification bar would drop to display no "bars." It does not switch over to 3G. I figured this problem would resolve itself once Verizon fixed its network.
Then I tried to send a text and it couldn't be sent. I tried to call someone and it would not dial out.
But these loss of connections are not persistent. Eventually, the 4G works for a bit then disconnects again.
The phone network seems to be doing this as well. Sometimes I can call/text, other times I can't.
I was considering wiping my phone and flashing a new ROM or getting the stock ROM from google to flash. However, I seem to be having trouble with clockwork mod. When I try to reboot into recovery mode it takes me to what I assume is download mode (shows an android knocked over on his side with, I think, a red X).
Is there something simple I can do to fix my data/phone network connection?
If I have to flash back to complete stock, then how do I do this without being able to access recovery?
If all else fails, will I be able to do a factory reset considering the current scenario? I assume I would need to do this before bringing it to Verizon for service.
I appreciate any help provided. Here are some other details that might help.
Rooted with stock ROM
4.0.2
Baseband I515.09 V.EK05 / I515.EK02
Kernel 3.0.8-gaaa2611
Build ICL53F
/edit/
I should have mentioned I had the most up-to-date version of CWM. I just reflashed it with ROM Mgr and it booted into recovery, so that's good.
Well ****. I went into CWM - Advanced - Fix Permissions. I thought hitting Fix Permissions would bring up another menu. Instead it fixed permissions. Hopefully I didn't do something stupid that I don't understand.

I flashed the GummyNex Rom hoping it was a kernel issue or an issue resolved by going from 4.0.2 to 4.0.3. It's been a little better it seems, but it did drop both networks once already and it's only been 15 minutes or so.

The new ROM definitely did not solve anything. I don't know what to do. I need to find a way to get back unrooted, unlocked, stock. Unfortunately, I'm running Mac OS X 10.4.11 which current SDK doesn't seem to support.

[Q] Wifi problems

Wildfire with
ROM: CM 7.2
Kernel: 2.6.35.14-InfinityPlay
Radio: 3.35.20.16
For the last year wifi, after a short period of time i can't download, I mean, some times i connect, get into market for example and download/update, but after some time i can't, it's not a market problem because i can't download from anywhere, regardless the app, but i can browse normally(!), the problem is only in downloading. Even if i reset wifi, go in and out of airplane mode, restart the phone etc, the problem stays. Maybe if i try the next day it works ok. I dont know how it occurs or when and why, nor how/why/when it gets fixed...
The problem started when I had rompuzzle 2.2.1 a year before, till now. Since then I have flashed stock rom with 2.2.1, jockerdroid 4.2, cm 7.1, and cm 7.2 that i have now.
I suspect it is a radio problem, but can't be sure.
*Also sometimes I have low gsm signal, even in well covered areas.
Any ideas/suggestions?
Thanks

You said you flashed stock rom, i suppose it was a stock rom from Android?
It really looks like you have a problem with your radio (like you allready say for yourself).
It seems you have the newest one, so try a lower version.
I you have troubles finding a radio because the host is down or something just pm me or try google.
Hope this helped! Kind regards.

try radio 20.10

i have tried all 3 radios, but the problem stays. But i have noticed that when i enable tether and i put in the console the command for reverse tethering *usually* it gets fixed until the next time that i disconnect from my wi-fi.

i have not the same but similar problem,after a while i get dropped from router,even if my phone says its connected...this started to happen after changing our router (which i couldnt and cant set up) and setting up "N" wifi network...i found two options,how to solve it..
1)use free app wifi fixer from google play store (which somehow manages to know if you are connected or not and can automatically reassociate with router again)
or
2)flash HCDR.Kernel_v4_Flashable.zip from op on this page http://forum.xda-developers.com/showthread.php?t=798471
maybe it help, maybe not.. gl

I have *temporary* solved the problem by following the reverse tethering guide... I don't know why but after doing this procedure I can connect normally to my router, and if it disconnects (rarely) I just repeat the steps of the guide.

[Q] BMB4 Wifi Issue (not wifi calling)

Since upgrading to BMB4 I am having an issue at work where my phone will not switch between access points properly. It appears to be a problem with the phone *disconnecting* from the access point when I no longer have a strong enough signal. If I walk from my desk to another part of the building, it still says I am connected with a strong signal, even though I am not connected at all.
In fact, several times when driving home I have looked down after realizing I haven't received any e-mails in a while to see that my phone still thinks I should be connected to the wifi at my desk.
The only workaround I have found so far is, if I go from my desk to another part of the building, turn wifi off and back on, then do it again when I return to my desk, or anytime I notice that my phone thinks I have a strong wireless signal but I don't.
I tried a full factory reset, but no dice. Had absolutely no problem prior to BMB4.
Anyone else seen anything similar? Any ideas? Anything buried in the service menus that could be wrong? If not, would rooting and reflashing the radio be likely to help (can you give me a link to the right one to try if so)?
Thanks!

The radio wouldn't have anything to do with it. You are probably a victim of just some simple file corruption. It happens, I see this more with OTAs than anything. That "transitioning" from one OS to another while attempting to preserve precious data.
I would recommend you root it, install "TWRP" 2.5.0.0 for your device (which is basically a recovery or "bios" for the device - or basically a kernel), and then install a ROM that has been updated to BMB4... off the top of my head, i would say you should give tweaked 2.0 a try. It's solid (others are as well, but i know for certain that one will give you zero issues similar to the one you are reporting.)
The links for twrp, with instruction on how to install can be found in the "orginal development section" and the tweaked ROM can be found in the plain "development section" of the forum here.
As I said, very likely that your issue can be resolved by starting 100% fresh. New system install (which is not formatted when you wipe data obviously)
So again, root, install twrp recovery, install tweaked 2.0. Follow directions to the T.
Good luck

I was reading and wondering if I actually wrote that question. That is EXACTLY what is happening to me since the update. I never have an issue at home, it is just moving from AP to AP at work and also being 'connected' when I am miles away from the AP. I don't really want to factory reset, so I tried turning off wifi power saving using "*#0011#" and that seems to be working...

WiFi not turning on?

Ok so a couple of days ago I installed a 4.0 ready radio on my galaxy s2 and then went on to install Jedi Knight 6 ROM (4.0.4 and radio is UVMC6) and after installation everything was working fine.. I was messing around for a while.. it worked today, I shut my phone off to charge it up real quick, and when I turned it back on my WiFi would not connect. Well not necessarly connect.. it just wont even turn on. When I go into settings and click WiFi, it just sits there saying, Turning WiFi on, and never changes.. I can't seem to imagine what could have happened to it, and I really dont wanna have to reinstall the ROM again because i just spent hours getting this one all set up to my liking...
Anyone got any ideas?
EDIT: BTW, I have tried many things.. Tried airplane mode to disable everything then turn it back on, obviously tried rebooting the phone, i have tried wiping cache in CWM recovery and also tried fix permissions in recovery (another topic said to try those..)
Nothing has worked so far, i'm about to try reflashing my radio, see if that works.. but I really really dont want to have to reflash my whole ROM.. So if anyone has any other ideas please help, i'll edit if the radio works..
EDIT 2: Reflashing the radio did nothing.. it's really wierd, the data, bt, gps.. all of it works fine, it's just the WiFi that's frozen turning on... cant get it to stop turning on and can't get it to actually turn on..
EDIT Final: Ok well, i guess nobody knows what might have been going on.. so I just wound up reflashing my ROM, which obviously fixed it.. i just had to lose all that time spent setting everything up... But oh well.. Kinda sucks nobody even tried to help..

+1 I'm going through the same thing now

I have been having this same issue as well. It started out as stock happening sporadically. One thread suggested rooting and removing my account. Problem still occurring. Tried flashing multiple ROMs and now WiFi hasn't connected at all always stuck at turning on. I have tried clear cache, fix permissions, as well as reinstalling ROM dirty and with factory reset. I'm hoping this isn't hardware failure because I just bought this phone used but it seems to be a reoccurring problem with others as well. Any NEW suggestions not given from quick Google/xda search?

I'd suggest to check your Wireless Access Point (modem or router) wireless settings for security, check and see if it's set to use WPA/WPA2, which is common on some modems/routers, change it to either WPA or WPA2 (preferred) not both, it's a known issue with WiFi networks and having it set to using both, I had the same problem before with my phone connecting to my WiFi.
Also if you use MAC Address Filtering on the modem/router, you should disable/clear that and let phone re-connect before enabling mac filtering again.

The problem I am having is not that it won't connect to a particular network. Wifi will not initialize on the device at all and is stuck in "Turning On..." state. I found more and more posts where people ended up having to send in to Samsung so I spoke with them and even though I purchased the phone used its thankfully still under warranty and they will be replacing it. The did not confirm whether or not it was a true known device issue but were quick to file the exchange for me.

sigh, me too!
Just started having this problem on 4.3.1
great.

In my case, I had to wipe system and data before reinstalling my ROM.
Though the only reason it was happening to me was because Beanstalk 4.4.2 didn't want to get past the splash screen when I tried to install it so I downgraded back to ICS 4.0.4 without wiping. Good luck getting this issue fixed. Also another kernel might fix thingz for you if your current one does not like your device.

I have a similar problem. After a while, WiFi gets disconnected. If I go in settings - wifi, i get the message "unfortunately, settings has stopped" and I can't get WiFi to work again until I reboot the phone. The Wifi works again for a couple of minutes then stops.
I have flashed various different ROM (CM11, PA) but keeps getting the exact same behavior.
I've rebooted in safe mode and I don't get the problem now.

[Q] CM11 WiFi doesn't connect

Hi there, my first post.
I've used arco68's guide to root my S4 mini LTE (serranoltexx) and flashed the CyanogenMod 11 M9 snapshot (cm-11-20140804-SNAPSHOT-M9-serranoltexx.zip), but the WiFi isn't working properly. Sometimes it connects (very rarely), but most of the time it just says "Connecting", "Authenticating..." and then goes back to say "Saved, secued with WPA" and the process repeats again.
I've tried flashing the following ROMs, but the WiFi isn't working properly on either of them:
cm-11-20140804-SNAPSHOT-M9-serranoltexx.zip (current)
cm-11-20140708-SNAPSHOT-M8-serranoltexx.zip
cm-11-20140813-NIGHTLY-serranoltexx.zip
Other things I've tried so far:
Using CM File Manager to delete contents of /data/misc/wifi and rebooting, as described here, but it didn't help.
Installed SQLite Debugger, went to Settings Storage > setttings.db > Global, where I wanted to change the value of wifi_display_on to 0 as described here, but it was already set to 0, so no luck here.
Changed the Region Code in WiFi settings (as described here) to United States, then to Europe, but this didn't help either.
Installed the latest nightly update, but still nothing.
Basically, I've tried everything I could find, but the WiFi still doesn't work, and I have no idea why. I don't want to downgrade to CM 10.2, since later when I decide to upgrade to CM 11, I'd need to wipe all the data and make a clean CM11 install. Also, I don't want to flash any other ROM except CM, so telling me to install Paranoid Android or anything else wouldn't help.
If you have any ideas how to solve this, that would be great! Also, feel free to ask for any additional details.
Update: I've just discovered that it connects to open WiFi networks without any problems (though I've only tried it on 2 so far), so probably WPA encryption or my old home router can be the cause of the problem. I can only change my home router to WPA (it doesn't work with WPA2), so I've yet to try it on another router supporting WPA2. If that works, it would solve the whole problem! I'm ashamed to say I haven't thought of this earlier...
Update 2: I just tested it on a WPA2-protected WiFi network and it connects without problems. The most likely conclusion seems that CM11 has some problem with WPA, so for the time being I'll switch to another router with WPA2. Hopefully gets fixed with the next snapshot!
