[Touch-packages] [Bug 1683066] Re: Broken DNS when using Three UK mobile internet (17.04 zesty)
Presumably NetworkManager, I just selected 3 Internet from the connections icon in the top-right corner of the screen (after disabling Wi-Fi from the same place). However, I'm now running Ubuntu 17.10 and systemd-resolve --status is showing the correct DNS servers when connected to 4G. So, this appears to now be fixed, and this report can be closed. ** Changed in: systemd (Ubuntu) Status: Incomplete => Invalid -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1683066 Title: Broken DNS when using Three UK mobile internet (17.04 zesty) Status in systemd package in Ubuntu: Invalid Bug description: When connected via 4G to Three/3 (UK), DNS lookups fail (though the internet is otherwise working).

[Touch-packages] [Bug 1683066] Re: Broken DNS when using Three UK mobile internet (17.04 zesty)
Update: The ISP redirect has now gone away and the internet now works. However, if the output of systemd-resolve --status is anything to go by systemd-resolve appears to still be using Google DNS instead of my ISP's (which seems utterly bizarre). I would surmise that while the redirect was in place, systemd-resolve was using Google DNS and access to the Google DNS servers was blocked until the SIM had been set up. This basically makes it impossible to set up the type of SIM I had (https://www.three.co.uk/Free_SIM_MBB/Order) on Ubuntu (I had to do that on Windows). That's because the SIM requires registration, which you have to do via mobile internet while using the SIM. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1683066 Title: Broken DNS when using Three UK mobile internet (17.04 zesty) Status in systemd package in Ubuntu: New Bug description: When connected via 4G to Three/3 (UK), DNS lookups fail (though the internet is otherwise working).
