[Q] When I turn wifi off, Note does not connect to 3G or HSDPA

Hi guys,
I have this strange problem, it even seems random.
After I turn wifi off, my Note does not connect to 3g anymore.
And I have to reboot the phone to get it working again.
Does anyone experience the same problem, or knows a sollution?
I rooted KK1 and flashed LA4 using Mobile Odin.
Cheers,
Daan

I've had this problem once, but it worked again after a reboot. Haven't experienced it again. It happened on KK5, but i flashed LA4 yesterday, so it's too early to tell if it will happen again.
It also happened on my Desire HD with MIUI and also while running CM7, so it might turn out to be a bug in Android.

I guess you had turned/switched off data network mode by pressing and holding the turn off button for two seconds.
Try and turn it off and see if it is the same symptom that you had before.

No, this is not the issue.

I manually set the APN settings for Telfort, removing MMS and setting it up for "internet" only.
Did a wifi on/off cycle, with a short interval and it seems to work.
Going to test with a longer interval. Not completely convinced yet.
Hope it's fixed.
---------------
edit: Not fixed!
On wifi for half an hour, turned it off and [email protected]#$% 3g does not connect anymore.
Maybe it's just Telfort. They don't have the Note listed on their website, but still.

My infuse 4g does this. I have to put it in airplane mode then back to get my data to reconnect. It did this stock and on serindipity 7. I couldn't find a fix either.

Annoying stuff! Cycling airplane mode does not work for me, only a full reboot.
But if you had the problem too, It could be that it's the network's (in my case Telfort's) problem.
Maybe I have to get my sim replaced, but I'm switching to T-Mobile in about a month.
So it's a bit of a pain.

I am currently using the infuse on o2 in Germany, but it did it on att in the states also. I can't wait to get my note. I am just waiting for it to be released on o2 over here. They have the black but I really want a white one.

Telfort used to be O2, it has been using KPN's network for a while now.
So it's probably not connected. Though it is a strange coincidence.
I'm off today, I think I'll walk by the Telfort store to ask for a new sim or something.
Maybe they'll have to flip a switch somewhere.

Yeah you're right, I have to troubleshoot properly. But it's such a pain
And I think I recall having this problem a few roms back as well.
I'm not sure because I was on wifi all the time.
But I have to wipe, I'll use titanium backup so it won't be such a hard blow
Man I'm going to pissed if it turns out to be the network

Thats a pain i was so tired of formating,..reformatting....coz many custom firmware have some error and new updates keep coming almost daily...and all ask to wipe for best experience..dat was when i finally decided to come bk to stock and stick to it...
yeah it doesnt hav those fancy colors and throbbing speed which a custom rom boosts about but...but hey everythin works flawlessly and i dnt have any tension of random reboots and alarm not ringing..or any smartphone related error to comeup...plus all my apps and schedule is there forever no reinstalling tension....enjoying my phone....

Okay, so I I did a full wipe and installed a deodexed rooted LA4.
I still have this issue.
Also tested on KK1 stock and still experienced this issue.
If it does this on KK1 and LA4 it's reason enough for me to believe it's the network.
I'll just wait for my T-Mobile plan to start. Meh.
edit: It seems to work just fine on CM9 :-/

Signal and Data Issues

Today my note randomly dropped signal, Then it wouldnt pick up a data connection even when it did have signal. Now it randomly jumps to 5 bars before going back to none :/ I Reflashed my rom and it made no difference. Have tried multiple modems, and even restored a backup from before any issues occured. Nothing seems to be working and i have no idea why! It couldnt be anything to do with the efs could it? I mean i haven't touched it at all and i do have backups.
Any help is much appreciated!

it's a shame no one has any ideas on this. Mine has just started doing the same thing. First noticed a week ago when my Dad was unable to call me. It's starting to annoy me a little!

I had i problem before, suddenly the downloading is so slow, i though my sim is the culprit. I tried to clean install and reflash, still the problem persist. The last thing did i format my internal sd and the problem is solved. I hope this help.

Hi Bud,
How's it been? How's the android development going on so far?
First of all, I would still commend you on your app (carbon tweaks) that have work wonders on my phone till now. Your app is simply awesome in making my phone simply 'sings'! . I truly appreciate your great efforts making that app carb. Such an amazing app indeed.
Anyway, going back on your issue. Have you tried changing ROMS already? Stock /ICS ROMS? is the issue still there amidst flashing different ROMS already?
Now if you say YES, How bout your network carrier or provider? have you called them up also? If not, you can try calling them.
The reason for that is, I too have the same issue as you have now. I was pissed off to the max on why I can't get full signal on my phone. Network connectivity would halt to a grinding slow up to the point of no connection and no signal at all.. then the signal would come back and it would disappear again. I tried everything as well, rebooted, flash ROMS, kernels, modems, wipe, but the issue woudn't go away still.
On the last effort I did, I called my carrier here in Portsmouth (AT&T) and I asked the operator if they have some upgrades going on on my location. And what comes to me as a surprise was that the at&t operator said YES they do have a network upgrade/s in my location and told me to just be patient and bear with them. I was about to blast them with all my frustrations but the girl operator was meekly apologetic and offered me some data packages added to my plan(that I simply can't refuse to deny).
Anyway, after that call, I waited till they've finally did an uptime on their end and in no time at all my my signal was back full bars and going strong on my phone.
Moral to the story is that... sometimes we are too pre occupied looking for answers INSIDE our phone that we fail to notice the OUTSIDE factors (that still counts) that makes our phone work also.
Cheers carb! :highfive:

Thanks for the comments about my app man I have to admit updates have been a little space lately but im young and not going to neglect my social life I really do owe you for the support though man! I will be sure to update you on any future projects I have
Turned out my issue was that my operator (o2) went down for most the country that day so that caused my issues and I just didn't realise xd

See? I told you it was just your carrier messing up with your connection.
I advised you on that and you called them up. It greatly saved much efforts on your time delving and sulking on the issue on your phone when the fact of the matter is.. it was not your phone at all having the issue... It was actually your carrier.
Next time bud, if your getting some weird connection problems.. my advice is, don't tinker directly down on your phone. Check your network/carrier first and see if they have some upgrades being implemented on your area.
Cheers bud!

Wi-Fi dropping constantly

Hi Everyone,
As title says, a few weeks ago I noticed that my wifi keeps dropping no matter what I do.. this being as i surf and not in sleep mode or anything like that.
How did it start?
when it happened this is what i did, went to GB rooted rom, flashed up to JB room paranoid android, all worked fine except i noticed wifi kept dropping, tried another jb rom ,same thing, tried ics kingdroid rom, same thing. So then I decided to go back to original official stuff GB, same thing.. wifi dropping, went to official ICS, still wifi keep dropping.
What I have done to try to fix it:
Tried different roms, networks, all settings in Wifi settings. Googled like 3 days straight, mostly this seems to be a galaxy s3 problem not a galaxy note problem. A few people said they solved it by giving it a static ip which wouldnt work for me as im on like 3 different networks, and by changing sleep settings to make sure it doesnt shut off during sleep mode, which i honeslty have no problem with. Someone solved it by switching rom, nothing i find applies to me..
So what do I do??
I would honestly appriciate any suggestion, this is a great community so I got high hopes Sorry if my question has been answered before but I dont belive so, i posted in noob thread any noone had suggestion so I hope I dont do anything wrong with this post.. cheers :victory:

What's your modem? Go to settings > about> baseband

The operation of Wi-Fi is a core responsibility. Try changing the kernel. Modem is responsible for the connection to GSM. If you change the kernel does not help, you probably have a broken phone.

well i have weak wi fi signal.. Most of the modems don't work for me.. Ddlp4 is the one i use..and no the kernel has nothing to do with wifi signal strength

Check your router and see if WPA Wireless network encryption is set to AES, if it is, change it to TKIP., see if you can connect after.
Usually it's nothing to do with the ROM, modem, kernel, android or even the phone itself, it might be your router setting that needs a change.

Know it was long since I made this thread but I wanted to report result, it was as above poster said. Rouer settings, finally found compatible ones after sooo manny roms, modems and other fixes were attempted.

Wifi Not Working On revolt or cyanogenmod 10.1

Hi All,
First post i think on this forum... I Have a HTC one and I flashed the Cynogenmod rom on it a couple of days ago. Right off boot my wifi would not access my network. it could see it and i could put in the password and it would say connecting but it would never connect. So I reinstalled the rom and still nothing the same thing... So today I got fed up with it and I put the Revolt rom on my Phone thinking that might help the wifi issue for some odd reason.. And still nothing. I don't know if i did something wrong in my flashing.. But I have flashed a lot of my phones and never lost wifi ever. I also have no idea where to post this or anything if you guys can point me in the right direction to someone that has had the same problem that would be great! Im going to post a video of what the wifi is doing in a few so you guys know what im talking about.
Thanks for the read.

I have the same problem . exact;y the same. ever since I have flashed my Galaxy Tab 2.0.7 with RC-2 cyanogenmod WIFI does not work . At times I regret flashing my perfectly fine default OS with buggy cyanogenmod .

Same here with CM10.1 (stable version). Whenever I try to connect to my wifi I get an "authentication problem." From what I can tell this is not from my end. Anyone know a fix or work-around?

Is it a 2 wire router

How to turn off going to 4G when low wifi connection? Phone keeps rebooting..

Got the phone few days ago, and its great. BUT, for some reason when the phone switches to 4G because of low wifi connection in my bedroom the phone will constantly reboot itself, real annoying problem obviously.
Ive been looking for a solution but havent found it..

I'd suggest contacting Oneplus support. This doesn't sound usual.

Been having the same problem, exactly as you described it.
I was wondering if my ROM had anything to do with it, are you running a custom ROM?
Were you able to fix the issue somehow?

I'm running resurrection remix nougat rom, and am still having the issue.
Current thought was to use something like Tasker to disable 4g when connection on wifi, and reenable when losing wifi signal.

Exact thought i had, but i forgot te app name thanks. Or maybe an NFC tag that disables it and enables on touch..

Found the solution on a oneplus forum. Remove the myproximus app. Really.

Hmm... try finding something that's involving "Smart Network Switching" and uncheck it if possible. I'm sorry if i didn't help but i don't really know about Oneplus's ROMs.
