[Q] Wi-Fi connects but doesn't work?

So I have somewhat of a strange issue with my wi-fi on my captivate. At home, my WiFi works great, no issuses. But when I go to my college, I can scan and connect to the WiFi spots but it still acts like I'm not connected. No data apps work at all, everything 'Fails to connect'
Using Wifi Analyzer, I see that its a strong connection. Even tried connecting to different channels, walking around trying different hot spots.. still no difference.
Why would my phone do that? Is there different kinds of WiFi networks phones cant connect to? But like i said, it see's and connects to the hot-spots there, just acts likes theres no data..

I had this issue last night when I was at a Hilton. IT saw the connection and connected but no data transfer. Found that when I connected to my laptop it redirected me to a page to enter the pswrd. So when I connected my phone again I loaded up the page from the laptop and entered the code. then it worked. Not sure if it helps

When you connect to the open wifi network simply open your browser and you should find instructions for that establishments network.

I started having a similar issue. I connect and get no data connection anytime I'm on wifi. It's happening on stock 2.1 and all 2.2 roms. After about two weeks of this, I called and am getting a warranty repair. I've had this phone since early august and never had any wifi problems.

When you connect to the connection that is not giving data, open your browser. Some places instead of useing a pin code use a webpage where you input the code.

Emergency Calls Only

I searched through this forum and saw a few threads but they were a little different than what I keep coming up with. I was wondering if anyone else is having this issue. Every once in a while my Note will switch over to Emergency Calls Only mode. If I go and enable airplane mode then disable airplane mode my connections will reset and everything will come back. I don't know if this is related to the SIM card, or the SIM slot on the phone. I feel like this is a software related issue. Generally this only seems to happen at work or when I'm in the basement for a long time. It's as if the phone is getting No Signal or a very weak signal for an extended amount of time and then finally switches to Emergency Calls Only mode, but doesn't come back. Also sometimes it will go into this mode and most things won't work, but for some reason the Facebook app can still access the Data Connection. I'll go to status sometimes and it will show Mobile Network State as Connected where Service State will say out of service or something to that extent. I even had Mobile network type showing as HSPA
Anyone else encountered this issue?

I am having the same issue, and this is driving me nuts! Usually it happens when I turn on wifi for a long while when my phone in screen sleeping mode. How to fix? not wanna restore my Note again as I did this step for 3 times already because of this issue.

The same issue. How to fix????????? Thanks a lot!

i've been facing the same issue since past 4 weeks. after switching over from stunner ics aokp rom to stock gb and now my phone displays no signal (bars) at all.. however this is only for a while and i do get reception after 10 mins or so.. now i'm on official ics and still face the same issue..!!?

same issue here, its getting frustrating i'm missing business calls because of this!

I had it over a few days on GB too, I tried reseating the SIM slot and it sort of fixed itself.
I am not sure whether that helped or a shutdown + battery pull is the savior.

After OTA 4.3 update Wii turning on and off

I just did the 4.3 OTA update and my WiFi keeps turning on and off on the phone. It loses connection and reconnects once a minute. Any ideas?

Took the OTA yesterday and I am not having that happen to me at all.

No issues here.

UPDATE:
Its not just my Wifi. Its the 3G too. All data drops out and connects again about once a minute. Spent an hour on the phone with Sprint. They tried everything including a wipe and hard software reset and still the issue is there. Only thing I can think of is that they snuck in some optimizing software or something. Either way, I now will need to go to a corporate sprint store. Really do not want to replace this phone that I have had for 27 days with a refurb, so any ideas will be welcomed.

I was having the same issue, do you live in an area with 4G? I don't and I think it was the cause. I think my phone was 'programmed' to think there was 4G around, but there wasn't. I kept seeing eHRPD under network info. I think it might be a 4.3 bug, bc I went back to Viper and it worked fine. Not really sure, but Amazon replaced my phone and now I'm scared to go back to 4.3 and get plagued with the bug again. I also think the new radio gave me issues, so I downgraded to the original radio also

This happened to me, it was a mixture of a damaged N antenna and bad sprint lte performance. Reverting to a g router fixed the problem for me. You should try a different router. Now fixing your regular signal, that's something you'll have a tough time with. I recommend you go to a sprint store and get a replacement asap though, my suggestion is not a fix, just a temporary measure. Curious, did you try the GPE rom by team nocturne? This issue started once I reverted from the TN GPE rom to stock. I think that rom may have damaged my radio/antenna. It's just a far fetched theory but plausible nonetheless. And a risk I took willingly, but still, I'm just curious to clarify if it was tinkering or sh*tty htc components.

I personally think it is just 4.3. I didn't have any issues with 4.1.2 with my WiFi or connectivity. I've even tested it and my WiFi drops like crazy only on 4.3 but is fine on 4.1.2, so I reverted back and haven't had any issues.

I found this just now.. towards the bottom there's a dialer code *#*#4636#*#* if you do that and change to gsm/wcdma/lte (something like that) it resolved my problem with 3G not working. Wifi might be my router

I have looked in the settings and sometimes the power saver will automatically shut 3G of it will not reconnect with a disconnected I switch to LTE / CDMA only have had no issues and also the wifi is meant to do that to conserve battery you should be able to disable the wifi in advance I'm not short just my thoughts
Sent from my HTCONE using xda app-developers app

Idk. In 4.3 all my settings were correct (*#*#4636#*#*) and I turned all battery conservation off and my data (3g and WiFi) would cut out intermittently while I was using it. I've tried that on stock and all other 4.3 ROMs, I think it might just be my phone not liking 4.3, but YMMV. Stuck on 4.1.2 until I get the Note 3.

It's a power save feature if you have enabled Power Saver. Basically if you haven't used the connection in a while it turns it off until the next scheduled update check or your screen turns back on.

I have been having the same exact issue and it is driving me nuts. I have problems at home, work and anywhere else I use Wifi so it is not just one router. I have tried numerous 4.3 roms and was about to roll back to 4.1.2 to see if that fixes it.
Was starting to think that I was crazy, glad I saw this post!

I'd hate to be (just kidding, I love being) the smart alec here, but your post title says "Wii turning on and off." I clicked on this thread wondering how your phone update was turning your Wii on and off.

I'm having the same problem after the update. Wifi turns on n off, so will my 3g/4g while I'm using it. Didn't have this problem before the update so I doubt it's hardware related.

Same here. I assumed it had something to do with the fact that they're working on lte in my area.

UPDATE:
At work (50 minutes from home) the 3G and Wifi spots I try are working fine. No strobe connection. But at home both Wifi and 3G blink. I know they are working on the antenna near home, so it must be the issue. Have tried shutting off mobile data while on wifi, tried both wifi antennas at home, can't seem to get the strobe effect to go away.

Yes, I messed up typing Wifi. At least with Wii up there get grabs people's attention.

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?

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.

Mobile Data connectivity Issues & Spen Button loose?

I know people have had Wi-Fi connectivity issues...but has anybody else had Mobile Data connectivity issues? It's a new phone and a new sim card but I'm still having issues? I had to reset my device in order for me to browse the internet or for me to send texts...TWICE within an hour. Any suggestions for this?
Also, is anybody's SPen button loose? I don't know how secure it's suppose to be, but if I run my finger back and forth as if I'm rubbing it, the button rocks back and forth as if it's loose. Not sure if it's supposed to be as secure as the home button on the phone or what

Wi-Fi and Network issues are being experienced by just about everyone. Because it's so widespread, this leads me to believe it is a software issue and we just need new radios.
Your SPen is like mine. Fairly certain it was made this way and is not supposed to be like the Home button.
Cheers

hum funny i havent had any wifi or 4g problems. I remember they said the s7 edge had wifi problems where it would randomly disconnect and not reconnect.
Which i didnt have that problem on the s7 edge either. (got the phone 2weeks after launch).
But with the note 7 no problems here. And my spend is pretty stiff no loose feeling on the button, feels almost like the home button

I've had really bad issues too. Like having to restart my phone to get data to work. receiving text messages late. Phone calls going straight to voicemail.

Same here. I simply notice that after an hour I dont seem to receive any kind of notification, suspicious. So I check my phone and keep getting pop up of "no connectivity please check your network". Both Data and Wifi will not connect. Even toggling airplane mode won't establish a connection. Only option is to reboot. This has been happening to me at least twice a day.

I have been having those problems too except it's with my data and regular service. If my phone loses service somewhere the only way to get it back is to restart the phone it's ridiculous and the signal is way worse then my wife's S7 Edge

id say report it to samsung via online chat and they will make a case about it and hopefully they will make a patch.
but as said i dont get that problem. Background data and everything works. my package tracking, ebay, facebook and all that work. No miss called or messages.

Definitely have an issue when I roam on AT&T then come back to a T-Mobile area. Have to put it on airplane mode and then back for it to acquire the network again.

I haven't had any WiFi issues, but I rarely use WiFi. I have noticed that my Note 7 like to switch to AT&T Edge (which is basically unusable for data), even when there is T Mobile LTE available. I constantly have to manually search for a select T Mobile for it to switch back. I don't want to disable roaming, because it's necessary where I live, but I can't seem to keep the phone from switching over to AT&T or get it to switch back to T Mobile when service is available. I just switched from a Nexus 6P which very rarely had this problem in the same area.

I too have experience Data loss where I have to toggle airplane mode or reboot. But this only happens at my residence which has a poor to fair T-Mobile signal.

I had no issues, maybe don't use phone often enough to notice, but I have been in and out of network and it works fine without any reset. but here is the funny part: when i went to activate my N7 (from home computer), I had to call rep, of course from my old phone. So while he is trying to switch me, he sms me some code to input (still on old phone), didn't get it, sends again, nothing still, then my old phone connection goes dead. So i grab my new phone, sure enough, I'm switched, new phone now works. That was around 9pm. 3AM my phone beeps, I got 2 SMS messages with codes from 6 hrs ago. Since they were originally send to my old phone, which worked fine like forever, I would speculate the issue was on TMO side, not my phone. So I wonder if some of the issues some of you experienced are coming from T-mo? I don't know, like somebody forgot to program new phone into system and things hang up,

I switched the mobile network selection to manual instead of automatic and turned off data roaming and haven't had this problem since.

I have had no issues like this? Why are some many users having issues with this phone. The Note 7 is built pretty dam well. All my friends i know have this phone and no issues with them as well. Before jumping the gun on issues please do research.

I'll try this and keep an eye out. Next step for troubleshooting will be to get the SIM activated that came with the N7 instead of using the one from the S7. I've read that using a SIM from a previous phone has information stored on it and could be the cause for some problems. That just doesn't make much sense to me since they both have the exact same T-Mobile bands but I guess you never know. Thanks for the tip!

I have noticed on my N7 if I lose service (building elevator, etc) and then come out into open air, one out of 5 times it never reconnects. I try to cycle through Airplane Mode and out, but that does nothing. The only way to get data back is by restarting the phone. Super annoying, especially when I have a password on the phone and a sim lock so by the time phone is back up and running to use, it takes some time. Very frustrated with this!

I just experienced this. Ironically I had full LTE Data bars but 0 connectivity running T-Mobile stock Firmware and NOT rooted.

At least 3 times in the morning my data has been off, showing full bars but no LTE, a reboot was the only thing that got it up and running again.
As for the S-pen I'd say it's semi loose when fondled..
