Captive Portal Check
A captive portal is a login page in public WLAN networks to restrict Internet access to the approval of certain terms of use. When you see a login page on a public network, your device uses a captive portal check. This allows the device to find out whether you have direct Internet access or not. In Android, for example, your device sends a request to a Google server.
Since mid 2019 I provide a free Captive Portal Check: https://connectivitycheck.sp-codes.de/generate204 You are welcome to use it if you like.
Setup in Android
To change the Captive Portal Check in Android, you need a terminal app or a connection via ADB to a computer.
To use http you can run the following commands with the respective method:
# settings put global captive_portal_use_https 0
# settings put global captive_portal_http_url "http://connectivitycheck.sp-codes.de/generate204"
To use https you can use the following two commands:
# settings put global captive_portal_use_https 1
# settings put global captive_portal_https_url "https://connectivitycheck.sp-codes.de/generate204"
Maybe you have to reboot your phone after updating the settings.
If you are using AFWall+ you need to give access to [1000] Android-System and in some cases [10040] CaptivePortalLogin to make it work.
Setup in Ubuntu
In Ubuntu, the file /etc/NetworkManager/NetworkManager.conf must be changed. Add or change the following lines:
[connectivity]
uri=https://connectivitycheck.sp-codes.de/generate204
Restart the network-manager:
sudo service network-manager restart
Setup in Firefox
Type about:config in the Firefox address bar and search for captivedetect.canonicalURL and network.connectivity-service. Set the URL values to https://connectivitycheck.sp-codes.de/generate204, the domain values to connectivitycheck.sp-codes.de. That's it.
