Is Gnome supposed to detect Captive Portals?

Help
1

When connecting to WiFi networks that require browser log in, Gnome does not prompt for captive portal. Firefox is smart to show a prompt, but since I have switched to Brave, which does not show a prompt, it is tedious to go into my WiFi settings to copy and paste the gateway address.

I see some references on the internet, mostly posts about how to DISABLE Gnome’s captive portal prompt. But on NixOS, I have never seen such a thing. Is there a way to enable this functionality?

If this can help, maybe you need to configure it in network manager:

Example (from 2015 :confused: )

Reference manual, that contains options from the 2015 post :partying_face:
https://www.networkmanager.dev/docs/api/latest/NetworkManager.conf.html

As a workaround I usually trigger it manually by going to http://neverssl.com/

This would probably the way to do it in Nix then: flakes/nixos/modules/networking/networkmanager.nix at 9d1dda48a9f5499014e224f92249c947fde3faf3 · ShadowRZ/flakes · GitHub

Would be good to provide similar functionality in an option. Will look into this later.

(You can ping me if I don’t give the PR after half a week month :slightly_smiling_face:)

this is exactly it

Firefox uses http://detectportal.firefox.com/canonical.html if this helps.

I tried this. Gnome now shows a question mark when internet is not working, but does not prompt to open a captive portal login.

Hey, so I see you’re looking for an integrated captive portal for your desktop, but check this out for a quick workaround:

xdg-open http://$(ip --oneline route get 1.1.1.1 | awk '{print $3}')

This command pops open your default browser and directs it to the IP address of your default gateway. If there’s a captive portal, it’ll trigger it. Super handy in a tight spot!

You should check out captive-browser: A dedicated Chrome instance to log into captive portals without messing with DNS settings.

It’s already packaged in the NixOS repo, so all you have to do is enable it.
