• Unable to connect to captive wifi at college


    Hi everyone,
    So here’s the problem -
    My college has a captive wifi i.e you need to login after connecting to the wifi. Antergos tries to connect to the wifi but does not get connected. Normal wifi networks such as my home network or my mobile hotspot work without any problem. Also this problem was not experienced by me with my previous OS (elementary).

    What I have tried already -

    Log from journalctl -u NetworkManager

    login after connecting

    they give a manual to how to identify at college?

  • @joekamprad We are given the credentials to login to it. But antergos fails to connect to the wifi itself. It doesn’t reach the login page.

  • Which browser do you use? I also had that problem connecting to wifi at a flex-work place I frequently use and somehow using Firefox I could log in and not with chromium, vivaldi and chrome.

    KDE/XFCE/i3-WM

    Everybody is a genius, but if you judge a fish by its ability to climb a tree, it will live its whole life believing its stupid.

  • @bryanpwo The problem is not logging in. The problem is that antergos is not connecting to that particular wifi. Even though wifi works without any problem at my home network.

  • I understand, but try open Firefox without internet connection, then connect with the wifi network and (maybe) the login page will appear. That’s how I do it.

    KDE/XFCE/i3-WM

    Everybody is a genius, but if you judge a fish by its ability to climb a tree, it will live its whole life believing its stupid.

  • @bryanpwo Nope, doesn’t work. As I said it doesn’t even connect to the network. I’m not assigned any ip and I can’t ping to any address.
    According to the log above it times out while dhcp transaction

  • Too bad, it was worth the try.

  • @ujjwal said in Unable to connect to captive wifi at college:

    state change: ip-config -> failed (reason ‘ip-config-unavailable’,

    i read somewhere that setting in ipv6 settings to link-local-only can do the trick, if not try to disable ipv6 and try again.

    ?

  • @joekamprad Well, that’s some progress. I’m able to connect to the network using but not able to browse anything I can’t even ping any address. Also ifconfig shows only an ipv6 address
