Request login to a portal on android devices without having to enter your browser! It would greatly improve the capture of passwords from sites like facebook, google . using the portal.

Hi @nikraupp I’m not sure I fully understand what you are asking for. Could you be more specific or provide any examples.

alternatexp commented Feb 27, 2017 •

I think @nikraupp is talking about the captive portal login notification that usually pops up when connecting to a public network with a captive portal. A window pops up on both Android and Apple devices when a captive portal is found.

Upon connecting to an AP, the device sends a request to a server ( gstatic.com/generate_204 on Android and captive.apple.com on iOS) to check whether it has access to the WWW or just the captive portal.

EDIT: I don’t think Wifiphisher triggers this notification/window, it doesn’t for me at least.

On my Android device, Wifiphisher does trigger this notification. Isn’t that the case for you?

alternatexp commented Mar 8, 2017 •

I’m pretty sure iPhones send a request to captive.apple.com and expect a file containing ‘Success’ as a response — which would work GREAT with this

blackHatMonkey commented Mar 8, 2017

iPhone/iPad specifically requires access to apple.com/library/test/success.html to «test» if the device is behind a captive portal or not, if it can’t reach that page, with the expected content, then it must be behind the captive portal and therefore show the webpage right after associating to the wireless. Other devices use their own URL, Windows Phones/laptops will use msftncsi.com for example.

The above is from SO. Since it is not able to reach that file and it should automatically label it as captive portal.

Please continue the discussion over at #524.

[Q] «Sign in to network» notification

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.

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?

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.

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.

Android Keeps Asking “Sign-In To WiFi Network”: 9 Fixes

Android smartphones are extremely famous because of all the right reasons. The android smartphones are pretty easy to use and are convenient to buy. On the contrary, some people have been complaining about Android keeps asking, “sign-in to Wi-Fi network.” For this purpose, we have created this article to fix this issue. Let’s check out the solutions then!

Android Keeps Asking “Sign-In To WiFi Network”

1) Router Issue

For the most part, the issue lies with your router. This is because when the Android phone is successful connected to the Wi-Fi network, it will test if the network can access the internet signals or not. We are saying this because, in the majority of cases, the Wi-Fi networks tend to redirect the requests to the login page. For the most part, “sign-in to Wi-Fi network” is because the Android smartphone is detecting that the Wi-Fi network is redirecting the request (it’s not for network authentication).

2) Change The Settings

In case you don’t think there is a router issue that’s causing the pop-up, you could try changing the settings. For fixing this pop-up, you have to open the advanced settings on the Android smartphone and move to the Wi-Fi tab. From the Wi-Fi tab, scroll down to “sign-in to Wi-Fi network” and disable this option. When it’s disabled, the pop-up won’t appear on your Android smartphone.

3) Software Update

Whenever you struggle with the network and connection issues, there are high chances that the Android software update is available, but you haven’t installed it on the smartphone yet. The Android software update is responsible for streamlining the functionality of your Android smartphone, and network connectivity are one of them. The software updates are designed to fix the bugs that might be causing connectivity errors. To check for the Android software update, check the steps mentioned below;

• The first step is to open the settings app of your smartphone
• You have to scroll down to the advanced setting (it’s at the bottom)
• Then, check the system update and look for the update status
• It will result in the on-screen prompts, and you need to follow them for installing the software update

4) Block The Notifications

If you have installed the software update on your smartphone, but the pop-up is still popping up, you can block the notification to get rid of it. Whenever this pop-up occurs, we suggest that you pull down the notification bar of your smartphone and long-press on this notification or the alert. When you long-press this alert, there will be multiple options, and you need to click on the “block” option. As a result, the notification or alert will be blocked, and it won’t bug you again.

5) Reboot

In this heading, we are going to talk about two different things. Firstly, if you changed the Wi-Fi and network settings, you have to reboot the smartphone after saving these settings. This is because you have to reboot the smartphone after changing the Wi-Fi settings as it helps set in the settings. So, if you changed the Wi-Fi settings but didn’t reboot, it can result in such errors. So, just tweak the Wi-Fi settings again and reboot the phone.

Secondly, if you haven’t changed the Wi-Fi settings at all, we suggest that you reboot the smartphone even then. This is because congested smartphones can lead to network errors. In this case, just long-press the power button of your smartphone or just switch off the smartphone. Once the smartphone is switched off, take about five minutes before you switch on your smartphone again. When it’s switched on, connect to the Wi-Fi, and we are certain this pop-up won’t occur.

6) Connection Optimizer

In case you are still struggling with the sign-in pop-up or error, we suggest that you use the connection optimizer. Connection optimizers are basically the apps, and you can download them from the Google Play Store of your smartphone. The connection optimizer will help streamline the Wi-Fi connection or network. Even more, a connection optimizer will “optimize” the network connection, and it will also help save battery life.

7) Protection Standards

When it comes down to the Wi-Fi networks with “sign-in to Wi-Fi network,” they use the captive portal to increase the protection standards. In addition, it uses IP-based filters blocking traffic or allowing traffic. So, when you log into the connection through your credentials, it will create the session for a smartphone. These sessions usually range from one hour to twenty-four hours.

So, when the session is completed, or you disconnect from the network, you have to tweak the protection standards of the Wi-Fi network. In such a case, you have to call the internet service provider and ask them to switch off the IP-based filters.

8) DoS Attacks

In some cases, this pop-up can occur when someone is trying to plant the DoS attack on the wireless access point. So, if you are thinking that a DoS attack is being planted, it’s best to switch off your Android smartphone for a few minutes and switch on the antivirus after switching it on. This is because the antivirus will protect the smartphone. In addition to this, make sure that you have chosen the WPA2 security standard for your network connection.

9) Reset

If nothing seems to fix the pop-up, we suggest that you reset the network because it will delete the network settings that are causing this issue. That being said, you have to reset the router. The router can be reset by pressing the reset button on the router through the paperclip. When you press the reset button, the router will also reboot and will delete the network settings. After the reset, you can enter the network settings again and use the Wi-Fi network again.

Secondly, you have to reset the network settings again. For resetting the network settings, you have to open the system from the settings and open the advanced tab. From the advanced tab, click on the reset options and tap on “reset Wi-Fi.” It will ask for confirmation, so confirm that you want to reset the Wi-Fi or network settings. As a result, you have to enter the Wi-Fi settings again.
