[Q] Issue in connecting to 2G/3G/H/H+

Hi,
I am using Note for more than 2 months now. I was using N1 before. And I had the same issue with N1 also.
Issue is,
In my work place, there are some area where no mobile would get a network. I used to stay connected always. But due to this network issue, my internet would get disconnected but would not get connect again when the network is back.
As I said I had this same issue with N1 but I normally toggle the Flight Mode to bring it back. But in Galaxy Note, this workaround is not working. I have to restart the mobile to get connected.
Does anyone have solution for this issue?

I don't know what you are asking. The issue is the connection gets lost when there is no network. But it's not re-connecting once the network is back. I have to restart the mobile to get the connection.

i meant is it happening only in your office or even in other place too..??
Try with different network. (AIRTEL/BSNL/IDEA or any other)

I think this is an intermittent android problem. I have no signal in my flat, and sometimes when i go out it doesn't reconnect properly, and i need to restart before i get texts/voicemails that i missed while inside. Its an occasional problem, and only happens sometimes. And usually it happens when i spend an entire day indoors so the phone has been without signal for some time.
This also happened on my hd2 with gingerbread and Ics. And also happens on my gfs HTC salsa. It's not a note specific problem as far as i can tell.

You are right. I had the same problem with my N1 too. But I never restart in my N1. Toggling the Flight Mode will bring back the connection. But its not working in Note.

i have this issue after i receive MMS.
i just go to settings, wireless and network, mobile networks, access point names, tap on my web connection (vf web since im on vodafone AU), and then just hit back. the 3g logo will disappear and then reappear as the phone reconnects to the correct wireless access point.

Data and Wifi completely drop, have to do airplane mode to turn it back on

I don't know why, but this is a consistent problem and it's getting annoying. I will only have bars, but no wifi or internet connection. This just randomly happens and I don't know what triggers it.
I have to turn airplane mode on and off to fix the problem. Is there something that is causing this?

What happens is data and wifi disappear and if I hit wifi it won't turn on. I have to turn airplane mode on and off and it starts working again.

I have had the same thing happen,but only once or twice,I chalked it up to my home WiFi threw Comcast ,I've been having major problems with my Comcast modem dropping WiFi or to slow of a connection,think I have to replace the modem just been to lazy,but I have the smart network switch on in my phones wifi settings so I thought maybe from the signals switching so much it froze or something,but yea it did same thing I had no lte or 4G next to my carrier signal,the wifi was not allowing me to turn it on,or scan for networks,wasn't even showing any so I did the same thing hit the airplane toggle and it came back.

Sorry i have no others solution for it.

I just posted a thread about the EXACT SAME issue. It only seems to happen overnight, but when I wake up in the morning my wifi has been turned off and my 4G LTE isn't working. When I try and toggle wifi back on it gets stuck and never reconnects/turns on. My solution has been to restart the phone.
I'm thinking since this seems like a rare problem, that this is a device-specific issue. I'm going to try and exchange mine this weekend due to this problem and hopefully get a properly functioning GS5 instead.

Have the same issue (made a post about it already in this forum). Usually happens when there is a large fluctuation in signal. Grocery store where I get no service results in no service when I leave the store as well. Have to cycle airplane mode like you described.
WiFi hasn't done it yet.
Another forum member suggested it may happen if using an older style SIM, which I am (from my S3). I haven't been up to change it yet. What SIM are you guys using?
http://forum.xda-developers.com/showthread.php?t=2744472

I typically have this happen when I'm at home at night, while my phone is plugged in and on wifi. Just disconnects at some point overnight.
I'm using a brand new SIM provided by AT&T when I upgraded in store.
Very strange issue and is random. For instance, it didn't happen overnight last night.

My S5 just started dropping data randomly and causing my battery to drain with almost no usage... I tested using Skype in a good 4G LTE area and will start out with 4 bars and the 4G LTE icon but as soon as I try to initialize a test video call over Skype the signal immediately drops to either no bars at 4G or it will go straight to E!? I haven't had this issue in a long time and it just suddenly started. At first I figured maybe they lost a tower but now this is going on almost a full week. I've got unlimited Data so I know that's not the issue, it has a brand new SIM... I'm going to AT&T and see if they have an answer or if they'll swap it out. Annoying!
Also annoying that sending a simple text will fail... ugh no root and now no data! :what::banghead:

I've had this happen several times, but only at my work. Reception is poor at my office, and the company WiFi requires browser-based login each hour, which I switch to many times a day.
The phone basically stops using all radios EXCEPT bluetooth, showing a circle with a line through it. I've been rebooting the phone to restore connectivity, but will try toggling airplane mode next time. I haven't noted any strange battery drain.
I haven't seen this issue when wifi is disabled.
I didn't notice it locked up a few days ago and drove home where cell reception is very good. The phone didn't recover until I rebooted it.
I have a brand new SIM from ATT and use a Gear 2 (which is greatness, btw)
I've done the following:
1. disabled the damn ATT hotspot app
2. Disabled/enabled the Wifi connection check setting
3. Did a full factory reset
This is getting close to a deal breaker for me.

As an update...
I have this issue basically every work day with the aforementioned environmental variables
Today, I:
Disabled Bluetooth (left the gear at home)
Disabled wireless
Switched radio to 'LTE/GSM/CDMA Auto' with instructions in this thread
The radios haven't locked up and reception is much better.
I'll try leaving WiFi/BT on and use my Gear again next week.

For anyone who is still interested, changing the modem setting seems to have resolved the problem for me. It also improved connectivity in weak areas a good deal.
Unfortunately you must enter the key sequence to toggle the radio each time the phone is restarted.

Xperia z1 fails to connect

Hey, im having an really annoying issue on my z1, sometimes it fails to connect to internet, I have full bars of connection and 3G or 4G sign next to it, but still nothing happens. I have tried putting it on airplane Mode and then taking airplane Mode off and triggering data connection off and on but they dont seem to help. It takes a while and then it starts working again for some time. My Z1 is completly stock and non rooted. And this is a few weeks old phone

No Data connection until I restart

Hi,
Has anyone had this problem - or any ideas what it might be?
Basically, every now and then I'll lose the data connection (but keep signal for voice and text). Turning airplane mode on/off doesn't rectify it, neither does turning off/on the data connection. However if I restart the phone, I'll get data signal straight away.
Any ideas?

what about changing network type from 3g to 2g and back ?

I used to have this problem on three UK with nexus 4 and 5. Might be a carrier issue?

I have exactly the same issue. Only cure seems to be a reboot. Haven't seen a pattern as to how or when it happens.

Funny you should say that, I'm with three at the moment...

I have the same problem. Though I'm from Russia and my network provider has nothing to do with Three (if only they exchange their "expertise").

I had this with my Z3C. Also on Three but my Moto G and Nexus 5 are fine. I think Bluetooth might have something to do with it. In the end I sent my Z3C back for a refund as Sony were no help at all.

Droid Turbo WiFi problems

Having issues with my WiFi. Been doing it for a week or so. Every few days and now since yesterday my WiFi will all together quit working. Says connected but I get no internet and can't access my gateway with it. I have Xfinity internet and all the other phones and laptops work fine on it. But my phone just straight won't work on the WiFi unless I hard reset my phone. Tried DNS settings and static IP address and all. Multiple reboots of both device and gateway. Can't seem to find anyone else having this issue. Any thoughts from anyone before I take it to Verizon?

Are you on the most recent update? The newest one fixes that problem.

I should be.

wifi sucks on this phone. I don't get the disconnects but it is very slow to load anything and everything. Pictures, web pages, whatever. Doesn't happen to the other 15 devices on my network. LTE works fine

When it connects I have no problems with speed. Despite being up to date with software I have to reset every few days for it to work here lately. I've even hard reset my AP and checked the firmware on it and everything else works fine before and after. Its just this phone. I finally got it working again after a reset last night so if it does it again I'm just going to Verizon with it. I'm no IT specialist but I know enough to try different things and still no remedy other than hard reset.

Believe it or not, I have this problem too. I'll be completely connected with nothing going wrong with my network, but I'll have no access to the internet. I'll go to my tablet or my roommate's phone and there will be no problems.

I'm still looking up other forums and Verizon as well to see what possibly could be up with it. If I find anything useful I'll let you know. It's pretty frustrating when I don't have unlimited data anymore like I had on Sprint. If I did I really wouldn't care to be honest, but Verizon's service has by far surpassed Sprint in Houston.

I've noticed that when my device sits idle for long periods, overnight for example, while connected to my home WiFi there doesn't appear to be any throughput. It seems to be connected in every other respect. Toggling WiFi off/on sorts it for me though. I know that I've read that this is a reported bug that is to be fixed, but naturally, I've been reading so much at so many different sites, that I can't for the life of me recall exactly which site it was. I'm guessing that you issues are somewhat different than mine?

Yeah. I can toggle or reboot or reset my AP all day when it does this and it will never fix it. I tried for 2 days of different fixes I've seen online but the only thing that gets it back is a hard reset.

Might be a fluke but just got home and no WiFi like I expected. Did a hard reset on my AP with the reset button instead of through my laptop by logging into it. Forgot network on my phone. Rebooted it. Connected and it was fine. Pain in the ass if I have to do it every day but if it works it works.

I also recently started having this problem. Frequent disconnect / reconnect to Wifi with no data passing through. I had to shut off my mobile data because it was increasing my data usage at home.

I also noticed this problem too. It shows I have Wi-Fi connection but no internet or email access. When I disabled the WiFi, internet comes back. It's also xfinity Wi-Fi router. That's only place I have Wi-Fi issues.. No issues at home. Maybe it's compatibility issues with xfinity router?

I'm using an Netgear AC1750 router...No issues with Wifi at work.

I'm pretty convinced its the Xfinity access points. I don't have WiFi at work as I work in a shop, but the WiFi at my in-laws (Sudden Link) worked fine this weekend. I am now I'm having the same issue with my laptop all the sudden as well is why I am really thinking that it's their hardware and not mine. Never had this issue with AT&T when I had them. Had already switched to Comcast before I got the Turbo so I can't say with 100% certainty.
Sent from my XT1254 using XDA Free mobile app

Sounds like it could be....if you have another Wifi router you could try it and disable the AP on the Xfinity modem. On my network, only the Droid Turbo has trouble with WiFi. I've got 7 other devices on there that all work fine.

Never set up an external router on it. I as well have 3 other phones, 2 other laptops and 2 tablets that all work fine with it. Xfinity just hates the turbo. Lol My laptop I think was a fluke as it hadn't been turned on in a few days. I just think it didn't want to refresh the settings until I released/renewed, then it was fine. I'll find out tonight when I get home anyways.

I also don't think its interference either. My father in law is an ex cop and radio operator. He has all sorts of repeaters and radios and all I haven't a clue about set up. If there was going to be any interference involved I'm pretty sure it would be there. Heh.

Yeah. Reading through some of that I never have hanging issues. Mine would just flat out not work at some points. Other than hard reset on the phone I have only found 1 way to fix it.
1. Forget WiFi network and shut off phone.
2. Hard reset my AP with reset button on back of it.
3. When AP is finished rebooting turn on phone and reconnect to WiFi.
