# Setup Captive Portal Check
|
||
|
|
||
|
In this article, you will learn how to set up your own captive portal check on different devices.
|
||
|
|
||
|
## 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.
|
||
|
|
||
|
## 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
|
||
|
```
|
||
|
|
||
|
## Fedora
|
||
|
|
||
|
In Fedora, 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 _NetworkManager_:
|
||
|
|
||
|
```
|
||
|
sudo service NetworkManager restart
|
||
|
```
|
||
|
|
||
|
## Firefox
|
||
|
|
||
|
Type [about:config](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.
