# 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.
