[Q] Samsung Galaxy Note II WIFI & 2G problems - Galaxy Note II Q&A, Help & Troubleshooting

I need help with my Note 2 (GT-N7100).
On a regular basis WIFI (and bluetooth) won't start or hangs. This occurred after I rooted the device and installed cyanogenmod cm-10.1-20130715-NIGHTLY-n7100. I should have known this rom is far from stable, but I was curious to try it. Wish I hadn't!
I removed the root (to unrooted) and reinstalled the latest stock rom from Samsung (via KIES). The problem stays the same.
I searched the net for solutions but no 100% cure so far. I tried some suggestions that I found like removing the battery, Sim and sd-card and pressing the ON-button for a minute and then rebooting. Sometimes this helps most often not...
What is curious about this is that when the device is in this state 2g indicates having several full bars even when the Sim is not installed!
Very confusing. Is this a software or a hardware problem. Can anyone help out?
Thanks from the Netherlands

Showing the bars without a sim is normal, that's how Samsung made the interface. You can try to reset phone to factory settings from the phone. See what happens.

Wifi connectivity issues

Hey all, I was hoping someone else has had this issue and has fixed it. I'm running a stock unrooted phone and when I connect to wifi, it connects to the AP and obtains an IP, but I cannot go out to any website or use any app that needs a connection (facebook app, etc). Things I've done:
Restarted phone
Factory reset phone
rebooted router
Tried other roms
Sent to samsung (they did a SW update) x2
Forgot the network, then reconnected
This is getting extremely frustrating as it's been this way since I've had it, but it got worse with the ICS update. Anything that anyone has tried and actually worked? The funny thing is, when you reflash the phone or do a factory reset, it works for about an hour then stops. Thanks in advance!
Have you ever connected that phone to a different wifi?
I encountered an issue a few months back where something went wonky and i had to completely reset my router and set it back up. Have you tried that too?

Yes, I've tried different wifi AP's and none of them have worked, while others are on them including mine at home. I have not reset the router and reconfigured it because it's a cisco and as such is a pita. I have looked through my config and cannot find anything obvious. But still, others are able to connect just fine.
Same issue here. Never noticed it until recently. Reflashed LE1 and it worked for a couple of days. Going to flash the galaxy note modem tomorrow.

I know it's a shot in the dark, but some said it worked....
Try to disable the "UPnP" in your router.
Let us know....
premiatul: I can't find anything in my router for upnp. If anyone knows how to disable it in cisco ios 12.4(11)T1, I'll gladly try it.
Autx: please let me know how that goes and if it works. Thanks!

Is darkside wipe a temp or permanent fix, from what you've read?
Noone else has any info that may help? I would really like to get to the bottom of this. Devs: could this be a driver/kernel issue over a hw issue?

Honestly, whenever I'm running a TW based ROM I find that wifi takes awhile to connect. Any AOSP (CM/AOKP) for me is nearly instant.

I'm running a stock, unrooted device. It connects to the ap and gets an IP address just fine, but data doesn't go across the connection when I go to the internet.

Thanks for the heads up that the note radio didn't work. Also, the new official update didn't fix this issue either. Maybe I'll just have t-mo replace the device since it's not happening to everyone. Thanks all for your input!
Quick question.
Did you De-bloat your phone? Ie did you remove any apps from the system directory?

Not since the last time it returned from Samsung. And it's completely stock and unrooted right now.
I did a factory reset and the wifi came back steady for the past day I was slot more selective with my apps as I think this may have been the issue.

I'm glad this worked for you. I can't tell you how many factory resets I've done and it fails every time within a day. I bit the bullet and did a t-mo warranty exchange. Seeing as so few people actually have this problem, I'm chalking it up to my having bad luck and got a lemon. I hope the new one works fine.
I'd rather have a new one then the same one fixed lol

Ive lost completely my mobile signal

Hey guys, this afternoon my phone turned off itself becouse of the lack of battery life and then it completely lost its capacity to connect to the network ( in order to make calls ).
Its kinda rare becouse when I press and hold the power button to get access to the power menu it says "airplane on" when its off really, even after disable it keeping saying the same.
Ive already restored it, wipe everything in the device but Ive got still the issue going on.
Any ideas? Please I really need help
Thanks

It might be a problem with your carrier. So, I suggest maybe trying to go into places where there is really strong signal and try there. Maybe reboot a couple times. If the problem still persists, then contact your carrier and ask if they have anything to do with it. Because, I almost guarantee that's the problem.

I've already tried it without success, and even called my carrier and they turned to me the network was fine.
I reckon is a problem with the fact that airplane mode is turning on and off automatically
I'm so annoyed with this don't know what to do really

can you try your sim in another phone? or another sim in your phone
I have already tried both options, neither of them worked.
So the problem is with my phone but I'm really in trouble since I haven't got the guaranty of this phone because I traded it for my old device.

Did you try a different kernel and / or radio?
What does your phone status show in settings? Baseband, Network, IMEI, etc?

Flash stock rom, delete superuser or supersu, and take it to your carrier to complain. If the problem persist on stock then it's really nothing you can fix. You should be able to get a new device.

The problem is that I havent got the guaranty since I trade this phone for another old one that I had. Hope there is way to repair it even if it cost money
Surprising this is... I just cane across this exact problem today. I just removed my SIM Card, put it back in, then rebooted. After a little while I got my signal back.

This happened to me last night. Took my phone off wifi realized I had no connection to my mobile network. Pretty frustrating, but flashed a couple different kernels and seemed to fix the issue.

Sim toolkit not working after rooting?

I am not completely sure wheter this happeneing after changing my mobile call and data plan or after rooting but I think it happened after rooting. Namely, the sim toolkit previously worked and I could access data on how much I had spent etc...now it doesn't. Is this common and is there a fix other than flading custom roms etc...I quite like the phone the way it is. Thanks all!
Try rebooting without sim card and then rebooting with it.

Nah I require root. I guess it is a sacrifice I have to make to have root. I don't understand though... I thought it could be because of Root call blocker as well but I disabled it and no change...

That doesn't make much sense to me, I already have stock rom rooted?
If this helps, I checked my applications and this application is supposed to be 0,00 B in size. I don't want to mess around if there is a chance I brick my phone. I will be the first to admit I am not too good with all this. Rooting was about top of my ability. So if anyone can help a damsel in distress out with a simple solution, I will be grateful.
I found stk.apk in system/app/ with root explorer, what will happen if I click instal?
Does this make any sense to anyone? I did do OTA update just before I rooted: http://code.google.com/p/android/issues/detail?id=34909
Try installing it
Sent From Samsung's Galaxy Note II Using Internet
The issue resolved itself when I removed GoLauncher. Don't know why. For now it is OK.
The issue returns itself. It turns out it fixes itself if I put the phone in airplane mode, restart it, then after it restarts, turn off the airplane mode (which requires sim code then). OK so I know what to do now, but it is slightly annoying that this keeps happening. Basically it happpens after every reboot if the phone is not rebooted from airplane mode. Any ideas?

Switches into and out of Roaming for no reason

My note 2 (n7100) on Stock 4.1.2 is switching in and out of roaming for no reason at all. Yeah that's pretty much the problem.
Any known solutions?
UPDATE: After some more fiddling around this issue disappears if I select GSM only. As soon as I select GSM/WCDMA(auto) this problem instantly reappears.
Does that strike something?

My father's Note 2 does the same. It's stock and unrooted.
Try removing your SIM card and putting it back again.

Trouble making calls

Hi. I just upgraded my phone and my wife's phone to official T-mobile 4.3. I rooted my phone using No Tripping Flash counter image. Everything works fine until phone looses the signal and after that I need to reboot phone to make calls, if I don't reboot it just ending calls immediately after I dial. My wife is having same issue with her phone. Anybody know how to resolve this issue?

What is your Current Baseband ? Can you try after factory reset ?
I am ok with doing factory reset on my phone since it is rooted and I have Titanium Back up but my wife won't agree to it.
See if after Factory Reset AND without restoring Titanium, are you able to make calls just fine ? If yes we'll find ways for your wife.
EDIT - Try My Backup Pro for your wife in the absence of Root.

It is same IMEI behind battery and in the settings. I think problem is phone loosing the signal and can't automatically find it. Sometimes instead of restarting it I put my phone in airplane mode and take it off so I push it to find signal.

Just to add to this, I am getting this randomly as well, and I am bone stock. I thought it was something to do with my new car since I use Bluetooth all the time now, but every now and then, I go to make a call, and it just ends the call immediately. The only resolution is to reboot the phone.

It probably is related to Bluetooth given the 2 antenna are so close. But it could be the new 4.3 Stock Rom too. After Reboot do you consistently get good signal till you use Bluetooth ?

Nope, phone is perfectly fine otherwise. I decided to see what T-Mobile support would suggest. They first wanted me to try and clear data/cache on just the Dialer app, however those options weren't available, so she took me to stock recovery and performed a cache wipe. Since the problem is sporadic, there is little else to do except to wait and see if the problem returns. They claimed this is a memory problem in the dialer app though, so I am not sure if that was a s.w.a.g. (sophisticated wild ass guess), or if it has been reported enough times for T-Mobile to actually seek out information from Samsung.
