[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!

"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.

HTC Desire and Google Talk disconnecting.

I have a annoying problem with the inbuilt Google Talk app on my Desire.
When I turn the screen off Google Talk disconnects from the server and I don't receive any new messages until I turn the screen back on. Google Talk displays a message saying "Lost connection to server. Messages will be sent when online".
I have "always-on mobile data" active in my network settings. Have tried to disable the automatic away status and even resetting the phone to no avail. I have also created a new Google account and that hasn't helped either.
I use my phone on the Aussie 3 network. Can anyone else with Desire on the Aussie 3 network tell me whether or not theirs is doing the same? Also my Desire is the Aussie Telstra branded one.
Just to note the only way I can use Google Talk properly is if I use eBuddy. eBuddy does not disconnect when the screen is off.
Hi danielhtc,
How did you go with solving this problem?
I too have a HTC Desire and use the 3 network in Brisbane. All was working fine with Google Talk up to a few weeks ago when I started noticing that I would just loose connection. Not sure if the problem started immediately after the Froyo update, I wish I paid more attention now.
Using the GTalk Service App from the market I see that I'm loosing connection all the time. At first it appeared to be random, and know it is almost everytime the phone screen locks.
I spent hours trawling the net and still have no answer. I have flushed the cached data for Talk, Factory reset the phone and even tried a new Gmail account with a factory reset of the phone, all to no avail.
I've talked with 3 and they calim they can't do anything to help me figure out what is going on as it not a 3 Australia supplied handset so no guarantees etc..
Strange thing is that it was working fine for months, and then all at a sudden problems... At the moment my money is that 3 has done something to their data network, however it still could be an issue with the phone. Unfortunately until I can try my account with a new Desire I wont know for certain.

[Q] "Sign in to network" notification

Hello,
A few days ago I started receiving a notification saying "Sign in to network" and below that the name of my carrier (see the screenshot). When I click on the notification, the browser opens up but does not load any page and just stays blank. At that time the notification disappears but then appears again after a while.
Has anyone seen this and do you know why it may be appearing? I am fully stock on 4.2 and unrooted.
Thanks!
Does nobody know?
Hi,
Same problem here (with Mtel network operator),
After updating to 4.2.1 the problem still persists. After I click on the notification it asks me to open in a browser and then opens this address for a second 173.194.70.101/generate_204 , and turns into blank page.
I think that when I walk away from one network cell to a another it asks me to sign into the new cell, but I am not really sure..
I`ll keep posting if I find the solution..
Not sure if there is any difference for GSM variants of Gnex, but have you tried updating your PRL & Profile?
(Settings>About Phone>MTel? system updates)
Sometimes after a flash/upgrade until I update my Sprint profile, service seems spottier. Only other thing I can think is that your phone somehow is no longer provisioned with your carrier, shouldn't be the case (I think) when dealing with GSM carriers since your SIM what provisions the phone, but maybe poke around settings to see if there is some sort of self-provisioning option, or call M-tel.
Check your APNs. You might need new/corrected APN settings or something. That usually shows up when you're on a network (usually WiFi) that needs a user/password or accept a disclaimer to get through to the internet.
However on a mobile network the APN should serve as the connection settings and the SIM serves as authentication to the network. Normally you wouldn't be able to connect to mobile internet. Does MMS work?

Hey, guys, thanks for your input. Actually, since yesterday I stopped receiving this notification all of a sudden. I have not done anything in the mean time, so I guess it was something on the carrier's end that got resolved or something.

I'm also facing the same problem. I'm on Vodafone Portugal and occasionally I'm with full network signal but I don't have internet. When I check the notification bar I have that same message and if I click it, it opens the same "empty" web page.
I'm running stock 4.2.1 yakju.

Hi there. Since this issue disappeared for me without any action on my end, I am assuming that it is related to something on the carrier's end. It may be worth contacting your carrier's support?

Hi there. By trial and error i found out that this icon starts appearing when the carrier throttles your internet speed. For example, I have unlimited internet traffic but when I reach 512 MB of traffic, the internet speed is lowered to 128 kbps. This is when the icon starts appearing for me. I also found out that if you dismiss it, it will appear again if you change connections (e.g. go from wifi to mobile). I find this behaviour annoying but I found no way to prevent it, as it seems to be something on the carrier's side.
I have the same problem only on my android phone (4.2.2) Samsung Galaxy S3 when I am at my home WIFI..
Could it be a virus. only diffference is the IP.. my browser tries to load this: 173.194.35.99/generate_204
i've blocked this IP. I can't even access play store now! rest all things work

i dnt think its caused by virus. Try check ur apn setting. Or reformat ur phone.
When you connect a mobile device with Google Play via WiFi, I have found that I must allow ssl traffic via port 5228. This connection I think is an authorization service deployed by Google. If you trust it or not, when you block outbound port 5228 (or if you block Googles' ip's) you will see the "sign into network" This is because Google Play assumes (poorly) you are connected to a WiFi network which requires a captive portal login (ie Hotel WiFi sign-in page). I am no dev but I believe the "generate_204" thing just forces the mobile browser to open a new tab so the login page will appear. It's not spooky just annoying.
Why did Google choose to deploy ssl over port 5228 and not the standard 443? Not sure, but it might lead to your Firewall's security policy blocking it as it did for mine.
I started getting the same notification on my nexus 5 recently. I had reached my data fair usage allowance and so it started appearing. I noticed that in the data usage setting the warning bar was set to my fair usage limit so I just raised the bar and hey presto no more warnings. Based on this I reckon when your data usage cycle resets each month you'll see the warning disappear until you hit your limit again.
Just done a quick test by dropping the data usage bar back to where it originally was, turned off WiFi and started browsing the web. The warning appeared again.

I have had this issue ever since I got this current phone (not a Samsung, but hear me out). From what I can tell, it is because it can not contact someone (probably Google) via cellular network. I also get this when on a WiFi connection with no internet (or very, very slow), further supporting this.
I am in an interesting situation. My carrier only has 1 APN for both MMS and data combined. However, I only get MMS with my plan, not full data. Therefore, I need to keep data enabled in Android to use MMS. Because of this I get this notification ALL THE TIME.
I'm going to try to get a logcat when it happens and see if I can find the exact service and maybe kill it. I'll update if I figure it out.

I have the same problem.It make notification at the time u linked to mobile data too, and i can't suffer it any more.So i have searched all internet and have no progress.But i found the way to block its notifications rather than voiding generation.
It's a notification generated from "Android System" and seems like a network-check function. So the problem have the mobile carrier's part(I'm in china, you know). And u can't block all notifications of "Android System" using tools like LBE or Gravitybox or anyothers cause it is useful all the time.
This Xposed Mod can help us: NotifyClean, it is the only tool to block several notifications u want of one app.
Use it in ur rooted system with xposed framework,and open it from xposed. It can log all notifications and u can tick the "Sign in to network"s in "Android System".

[Q] HELP - Can't log into protected Wi-Fi – Galaxy S3 stock ROM

I have a T-Mobile Samsung Galaxy S3 rooted with the stock ROM running (Deodexed_T999UVDLH3.zip). Everything on the phone is running fine, and I have no problems accessing the Internet on either Wi-Fi on my home or public networks or over 4G.
I am having one odd issue, though. In my office, we have a Guest Wi-Fi Network that I have typically connected to. I get 4G in my office, but the Wi-Fi saves on my data plan. Logging into the guest network requires opening the typical splash page and clicking on the button to accept the general terms. Now that I have routed the phone, I cannot log into this guest network.
When I try to log into the wireless connection, I can open the browser, and the splash page comes up, but when I click on the accept button, the phone vibrates once, sits for about five seconds, then vibrates three times quickly and shuts the browser down. The same thing happens if I click the link to open the terms and conditions page. The Wi-Fi connection under settings shows as connected, but I cannot get any data to or from my phone. The Play store times out, and the browser will only load the splash screen for login again.
In searching this forum, I found posts that instructed clearing out all of the cache and the cookies, and I have done this. It did not resolve the issue. I did not find any other posts that seem to relate to this problem.
I am a relative newbie when it comes to rooting, and this forum has been extremely helpful. I'm hoping that someone may recognize what is going on with my issue, and can point me in the right direction to get it fixed. Any help you can provide is greatly appreciated. Thanks!

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

A similar thread was made on the subject - link here https://forum.xda-developers.com/galaxy-note-10+/help/android-10-5g-wifi-dropping-t4037661
For practical intents and purposes it's almost like when the issue happens the phone is not able to resolve a DNS query. I base this on 2 hypothesis - first being that the phone is still connected to the wifi access point and can still access LAN resources. The second being that the phone must either poll the internet (i.e ping a specific address) on a regular basis. If the poll was unsuccessful it flags the connection as "WiFi connected but no internet".
The things you can try are:
update the firmware on your phone (if not already)
factory data reset (read note 1 below)
reset network settings
try a different wireless router (read note 2 and 3 below)
disable private dns (read note 4 below)
If you use tasker create a routine to automate a temporary solution (read note 5)
Notes
The issue maybe a corrupted setting within the phone. I have had similar issues before (not with just this phone) and a factory data reset helped. One thing to take note of is that after the phone had completed it's factory data reset I did not attempt to restore a backup. This is important to keep in mind because any issues that were present (due to corrupted settings) would exist also in the pre-factory data reset backup you made.
With my previous router I had this issue but had since replaced it with a Wifi 6 capable router. After getting the new router I have not had any further issues what so ever. Also make sure your wireless router is up to date on it's firmware. It maybe possible that the wireless router you have is old enough (from when it was released, not from when you bought it) that a replacement might be the only way to resolve the issue.
To help rule out a wireless router issue try using a different one. You can borrow a friend's internet connection for a while, or a public cafe or what ever. Point is you are trying to see if the issue happens again when you are using a totally different wireless access point (by totally different I mean hardware/model and not just renaming the SSID).
I had the issue happen when using private DNS. For what ever reason the issue was with the DNS provider I had choosen. Turning the Private DNS setting off helped resolve the issue. After turning the setting off it may take a bit before the phone recognizes it was turned off, but you can hasten this process by toggling WiFi off and back on.
The Tasker option is one I did and it worked quite well. You may need to adjust the routine to suit your particular needs but it's basically what is at this link here. Best part of this option is that you can have it only activate when your connected to the problematic wifi access point and every X number of minutes (helps ensure that you use it only when needed). The routine (when setup correctly) should run every 10 minutes in where it attempts to access a website and assigns the results to a variable. The variable is then checked to see if it matches a specific result (in this case an error code), and if it does match it will toggle WiFi off and back on (after a brief pause/wait period between toggle off and toggle on) automatically. Granted it sounds like a lot of work, but it's really not that complex. Also I consider this is a temporary solution because you may find that on later firmware updates applied to the phone (or you may end up getting a new wireless router) the issue will have been resolved.
