Public bug reported: Where I live the only ISP is giving DSL customers a cheap Huawei DSL modem/WiFI router combo device. Except that their customers know absolutely nothing about configuring it, and when the rare customer does ask to configure it they refuse to give them the username and password, claiming that the device belongs to the ISP and only being "loaned" to the customer. Unfortunately they provide it out of the box with IPv6 support enabled over the LAN. The connected WiFI devices still receive an IPv4 address in the 192.168.1.x range, but some kind of IPv6 support is enable for devices that support it. This does not pose a problem for Windows, Android, and iOS devices, apparently because they don't support IPv6.
But unfortunately Ubuntu devices don't work with this configuration. The device connects to WiFI and receives a 192.168.1.x address with DNS and default gateway correct, but it can't access the Internet. The way to fix it is: 1. Open NetworkManager "Edit Connections" for the connection 2. In the "IPv6 Settings" tab, set "Method" dropdown to "Ignore" 3. Disconnect and re-connect to WiFI, and it can access the Internet. These steps are unnecessary. It seems like NetworkManager should always disable IPv6 whenever it receives and address in the private IP space, because nobody will use IPv6 on a LAN. This issue is becoming increasingly common around the world, and it makes Ubuntu look "complicated" to new users in comparison with the antiquated proprietary systems that don't support IPv6 and therefore work great out of the box. Thanks for considering this improvement. ** Affects: network-manager (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1463169 Title: NetworkManager should disable IPv6 by default with private IP addresses Status in network-manager package in Ubuntu: New Bug description: Where I live the only ISP is giving DSL customers a cheap Huawei DSL modem/WiFI router combo device.
