Wi-Fi bars full but no internet connection

Hi. I just bumped into this issue and I am really annoyed because I don't know why it appeared. The story goes like this: I wanted to search some app on the PlayStore and as always, I turned on the Wi-Fi, waited a couple of seconds and the full signal bars appeared, as they should and the network appears also "Connected". But, when I try to acces the PlayStore, it keeps loading and loading, the same thing goes for Google search, mail sync or anything else that involves an internet connection. The catch is that the problem isn't with my router, because it is working properly, my laptop and my sister's phone can access the internet. I have tried forgetting the network and re-entering the password as well. I don't know if it is related, but at the same time when the internet was not working on my phone, a message appeared on my screen at a 30 seconds interval, and the message was "Backing off 30000", "Backing off 45000", etc. I rebooted my phone, I wiped my phone, I thought it would help, but it didn't. I hope you can help me solve this problem. Thanks in advance.

[Q] Wi-Fi keeps disconnecting and telling me that "Sign in is required" 2 days ago

[Q] Wi-Fi keeps disconnecting and telling me that "Sign in is required" 2 days ago
Hi,
I have been looking in internet and didnt find any info about this kind of issue...hope somebody can help me with this.
The thing is that 2 days ago, when I return home I realized that my Wi-Fi wasnt connected, and in the Wi-Fi networks, under my Wi-Fi name I got the message "Sign-in is required" (which is weird because I neverd had to do that), after tapping on it and connect, it launches the message of "Sign in Wi-Fi network" and take me to the browser where it tries to open "google.es/?gws_rd=ssl " but nothing happens. Then after a couple of minutes I got disconnected with the message "this network has been disconnected. your sign-in timed out" and then goes again to the "sign in is required".
This issue only happens with my place Wi-Fi, at my office the phone connects to Wi-Fi and works like before and without any problem. And at my place it only affects to my Note 2, my gf S3 has no problem, some older devices like HTC Desire HD or Chacha also can connect to internet without problems, and the same goes for my laptop and ps3.
I tried changing network password, name and nothing. I removed the pass for my network and still the same...and after reseting the router no changes.
As far I remember the day the problems started I almost didnt use my phone, and didnt change any settings at all.
As for the device, I'm runing the original rom with android 4.3. On monday I had a small update throught Kies to "PDA:NE1 / PHONE:NE1 / CSC:NE1 (TGY)" and it worked perfectly.
any idea of what could be the problem?
thanks!

is there any solution to this?
I am having exactly the same problem with a brand new galaxy trend plus. since we bought it and brought it home yesterday I've searched all over the internet and tried almost every advice I found on problems with wifi connection, but with no success. the phone is running on android 4.2.2, and we have another phone and a tablet on 4.2.2 which never had any problems with the wifi.

I'm seeing what I think is this same issue on my Galaxy S5 on our corporate network. We have a captive portal page that needs to be accepted every few days, but once you accept once, you're good for that period of time. However, after that first captive portal, my phone is assuming that every time it connects there is a captive portal, so it isn't connecting automatically. If I forget the network and re-connect after I've hit the captive portal for that first time, it works as expected and will auto-reconnect if I roam to a different AP, etc.

need help!
Hi everybody,
Is there a solution for that problem? I did everythig that told in manу threads but still got nothing helpful. I found the Google developer's thread so it is suppossed to be not a bug but a special feature that no one can turn off.
I usually use pablic WiFi captive portals and nowhere I can set stable coonection on my Samsung Galaxy Tab 3 SM-T215.

I found a solution!

It's described here: http://forum.xda-developers.com/showpost.php?p=58252752&postcount=38

"Sign into network" auto disconnect
The sign in autodisconnect function is caused by an internal android system app called Captiveportallogin. I used romtoolbox to freeze it and configured my network manually after a day of it auto disconnecting.

Unfortunately Bluetooth has stopped

Within the last week I've started to experience an error that says "unfortunately bluetooth has stopped" dozens of times per day. If I am in a public place like a mall or an airport then the error happens literally about every 5 minutes. When the error happens I can look at my settings and see bluetooth has been turned off and it will automatically turn back on until the error happens again. I am stock and not rooted.
I've researched on the Internet and this error appears to be related to a Bluetooth bug in Android 4.4.2. Apparently every time the phone sees a Bluetooth device, it registers that device in a log regardless of whether you connect to it or not. Once the log reaches some high number that from memory is somewhere near 2000 devices, the error occurs because the bug is that the log doesn't flush itself and can't handle the next device that sees.
That matches my experience. I can connect to my own Bluetooth devices including my android wear watch but when I am in public, presumably where there are a lot of Bluetooth Beacons, I will start having the error in my android where watch dropping offline. At that point the only thing that you can do is restart the phone and it will work again until it sees another Bluetooth device. It's a horrible bug.
The only way to reset the log appears to be to reset your phone. With me being stock and not rooted, are there any options for a mass backup and restore of my phone's apps and data without having to actually set the phone up again and deal with each app individually? I'm going to be getting the new LG flex 2 when it comes out so I don't want to spend much time on this but would love to fix it if it was easy.

It's ASTONISHING Google has not offered a fix for this HUGE bug, which is affecting thousands of people.
Shame on them.

I was having the same problem. A quick google search said to go into the Settings, Application Manager, All, Bluetooth and reset the Bluetooth app. I went ahead and cleared data and cache. Hopefully this works. I really don't want to do an FDR.

I'm having the same issue although I tried clearing the data and cache, forced stop the restarted my phone - when my phone came back up it still had my other 2 bluetooth devices in the memory so I thought that by forcing stop it somehow didn't really clear the cache and data so I then cleared those again and then when back to the bluetooth app - they were still there even though I specifically cleared the data. Then I tried clearing and then just restarting the phone after it cleared - to now avail. : (
I've been searching for an answer to this problem because I have bluetooth speakers I want to connect to but every time it gets to the searching for devices and it sees it the bluetooth app crashes and then restarts and crashes when I hit the search for devices again. over and over again!
This totally BLOWSl -

Unable to stay connected after s7 Nougat update?

Since i upgraded my s7 to Nougat, my Smartwatch 3 has failed to stay connected to the phone. Most of the time it refuses to connect at all.
Ive googled for days now, trying all of the usual stuff including clearing the bluetooth cache and wiping the system cache, unpairing the watch, safe mode, forgetting the watch and repairing, removing android wear.
The setup starts working and then during the sync stage, i start getting the bluetooth share has failed message several times although most apps seem to sync eg watchmaker pro and strava.
My question is should the Smartwatch 3 still work correctly with my phone even though the phone is on Android 7.0 and the phone is on 6.0?
Thanks
Andy

My SW3 works great with my HTC 10 running Nougat.
Have you tried doing a factory reset on the watch?

That was going to be my last resort!
Think I may be there though
Thanks,
Andy

Just completed a full reset. Paired first time but crashed several times with bluetooth share has failed.
Failed to complete and no longer connects

I'm also on 7.0 and no problem at all. Maybe is something wrong with your BT from S7, unfortunately I have to tell you to try try factory on the phone, if you can't find out. Samsung for me have strange way of using there BT connections maybe this is why.
Hope I'm not starting any flame but.... that's why I'm on HTC (and not only), Samsung (S4 and S5) phone several times have blocked my car BT system...

Thanks for the feedback. I have done a factory reset and it made no difference, but maybe it is a Samsung issue as nobody with an S7 has indicated they are using an SW3 with nougat.

I'm having same issues. Updated S7 edge to Nougat last week and everything running fine until SW3 ceased connecting today. Tried everything other than factory reset on phone and cannot get connection to SW3.

Mine has started working after a month of failing.
It's been connected for a couple of days without any disconnections.
The latest attempt was no different to any others.....
I switched off the watch, wiped the system cache, restarted the phone and watch and lt connected.
I left it alone as apps started to sync and there were some bluetooth share has stopped messages but everything works!

If you use in the phone the option "deep kill all apps" in recen menus... you will have sync problem... It happend me with my op3...

I have similar problem with my S7. It works fine with bt connection as long as i connect the watch over wifi. Then no more bt connection is established, only wifi. Turning off wifi makes the watch permanently offline.
Very annoying as my watch can't sync when outside my wifi range.
Any solution so far?

Nexus 5X Unable to connect to WIFI

Hello, This is my first thread in XDA DEVELOPERS.
My Nexus 5x's wifi is not connecting. 4 months ago, my phone boot looped . And I don't have any warranty. I tried every possible way to bring it back but failed. I factory reset then performed a rescue OTA Which was tough to do because the phone was boot looped. But I didn't give up. I contacted the Chinese Repairman(Mr. Huang Jinhui) via WeChat(the one Cathair2906 mentioned in his 4GB RAM upgrade article). I sent my phone to China. And the phone was fixed + the RAM also upgraded from 2GB to 4GB :highfive:. He sent me a video in WeChat that my phone has been fixed and he mentioned that there is an account lock. In his video, The WIFI was connected to his network(not even the caution mark in wifi signal). I am very happy with that. But the Chinese man couldn't go to the home screen as the phone was reset(I performed a rescue OTA after the phone was bricked that's why). My email & password was needed. But in China, Google server is disabled so he can't bypass FRP even if I give him my email & password. While everything is available in Shenzhen, China, I told him to buy me a new battery of my phone and charger and cable. He changed the battery and send me a clip. Everything was fine. But when I got my phone in my hand and tried to go next, I couldn't connect it to any WiFi Network:crying::crying: . It load and then "Unable to connect" caution appeared:crying:. My phone is in Android 7.1.2 with June Security Patch Level. So after watching some youtube videos on how to bypass FRP lock, I followed some steps and went to settings menu via Talkback option. Checked the phone memory, it shows 3.6GB Ram :angel:, that's fine. Then went to wifi option and tried to connect but still failed. Tried WPS push button, didn't work . Then one of my friends told me that since the battery has been changed, the time and date has been reset & wifi won't be connected if there is a major difference in time. I checked the date & time and it was not correct. Then I was hopeful and relaxed that if I set the time and date correctly, the wifi will be connected.
I set the current time & date from settings and tried to connect it to my wifi network......................... Still, I failed :crying:. Turned it off and on then tried again.......... still, it doesn't connect. No "Authentication Error" message appears. In WIFI Settings menu it shows just "Saved" instead of "Connected"
It's not like that my phone can't search WIFI. Everything is okay, WIFI can be turned off & on. It can search WIFI Networks. All okay, just one problem, it is not connecting.
I can't bypass the FRP lock if I can't connect my phone to WIFI. I'm facing bad time after bad time. I am so near that I am finally gonna use my beloved Nexus 5X again still I cannot because of the new found problem "Not connecting to wifi".
If anyone can help me, I will be really very very grateful.
Thanks
