    If you have a router going bad...would that cause a no connection, connection error?

    Kelly,
    5 phones have all behaved the same way. Serious wifi issues. Unexplained browser lags or lock ups or you could call it a freeze thats lasts several minutes. If I drop wifi and use my LTE connection it behaves just fine.
    I was recently in the hospital for a serious pneumonia. Ohio health has a very powerful guest wifi network that is unsecured. I had my GN2 with me and it was a pleasure to use on wifi. There was not one instance of grief.
    That makes me believe the finger pointing is at the linksys WRT330n router. There are no upgrades available for the router she said it is a legacy router..whatever that means.
    I have just ordered a Asus AC66U dual band router.
    What other symptoms are there of a router going bad?

    An update to my previous posts.

    I know the original post was about cellular data, but I was seeing the same issues on wifi. I even said in my post that I was not going to be able to test my cellular data for a few days as I was going to be home on wifi all weekend.

    After the OTA security update the other day, my wifi issues seemed to disappear. Well, they resurfaced the next day. I am back to having to turn airplane mode off and on to get wifi working correctly at times.

    I am still trying to figure out if it is an app or a driver/antenna issue as others have mentioned.

    You might not notice on a computer as quickly, also could be your actual internet or some router settings.

    You should try just turning off data, instead of airplane mode and see if that helps.

    Seems all major carriers, AT&T, Sprint and Verizon put a Wi-Fi program on their phones. I would suggest disabling those programs.

    I did disable at&t's wifi app when I first bought the note a few months ago.

    Most of the radio issues started with the 4.1.2 update for me.

    I just got my Note 2 last week and had trouble with losing my 3G connection on Sprint. Wifi always works. I have to reboot the phone or toggle Airplane to get 3G data back. I talked to Sprint and they suggested as a test to disable LTE which I did (no LTE in NH yet). This seemed to have fixed it somewhat. Last night I turned it back on and got it to fail. Fixed it, turned Wifi on and it has been fine. I drove from 3g at home to LTE in the way to work and 4G LTE works fine (I mean awesome!). So far I haven't lost the data again.

    I should say too that when I was losing 3G data I could still make calls with no problem. The Up arrow on the 3G would occasionally blink but never a down (anyone remember the Samsung Moment "up arrow of death" problem?).

    Anyway, FYI. I hope there isn't an intrinsic problem with LTE in these phones...

    It's not that there is a problem with LTE on the phones. I think there is more of an issue with LTE technology.

    This is one thing that makes me angry about AT&T, they took our ability away to turn off LTE when necessary. Now you have to remove your battery and SIM to turn LTE on and off.

    Nah, it's a problem with LTE on the phone itself. LTE is firmly established here in Houston. Also, my LTE iPhone 5 had no problems with signal loss and data connection.

    Had a long chat with AT&T rep. online yesterday. It appears there is something wrong with the SGSN (?) not registering, thereby kicking my internet connection off after a few minutes. They are replacing the phone under warranty and I should have a new (refurbished) one by the end of the week.

    Angry Re: Note 2 loses data connection

    I have t-mobile and my Note 2 started this a couple days ago. Nothing really seems to fix it.
    One thing I did notice is that the data problem all started when I hit the "2Gig" mark for the billing period... but why would that matter when I have paid for the unlimited package. Way above 10Gig.
    One other thing.... it will go as far as dropping the entire signal!!!

    Anyone have a FIX for this?

    (little later)
    I just did a factory reset!..... NO DATA CONNECTION AT ALL! At this point sounds like a warranty swap to me!!

    I know this is an old topic, but I've been having this issue with my AT&T Samsung Galaxy Note 2 as well for the fourth week in a row now. My phone will say I have 3/4 bars of 4G LTE, yet I can't connect to the Internet, not even to retrieve my email. I've chatted with more than three AT&T service reps now, and my issue was even escalated last week, and now I'm just waiting for my replacement device. I even got my sim card replaced on the second week of this ongoing issue, and that did not seem to resolve it at all. I'm hoping that I won't have the same problem when I get the new phone either today or tomorrow. If not, I might just have to cancel my plan because I don't think it's right to have to put up with this for almost a month now. I even did a factory reset on my phone, and the issue still persists.

    I finally got a new device about 2 weeks ago. I was constantly resetting the data connection and just got tired of it. Since then, I haven't had any issues. Good luck with yours, I think there was just a bad batch!

    I am supposed to be getting my replacement phone in a week or two (on back order).
    Tech support never got back with me so I went to store and they said same thing, must be bad batch. Since it isnt just one carrier.
    Hope all goes well for everyone, and hope my new...er one isnt part of the same batch! LOL

    This may or may not solve your issue. I received my warranty replacement phone a few weeks ago. Right off the bat, same problems, loses data connection when not on wi-fi. Got a free app from the Play store and started looking into the mobile network itself. What I found was that even though my status bar indicated that I was in a 4G LTE area when at work, the phone signal was not staying in LTE. It kept on switching back and forth between LTE and HSPA+ and through the switching it was losing the data connection. AT&T maps say that I'm in a full coverage LTE area, but this does not appear to be the case. As most of us know, you can't switch to the the 3G network easily on this phone. However, if you know the number code to dial and the correct settings, you can disable the 4G and LTE networks. Now, when I am at work, I run the code, and set the settings to 3G HSDPA network and because it is not constantly trying to find a signal, it never loses connection now. Sure, it's not as fast, but right now I'd settle for constant on than fast, especially when watching Netflix shows.

    AT&T replaced my sim card as well, it worked for about three days and then started losing connection again. For the last month my connection comes and goes at will. I am so fed up.
