I don't have the same XPS 13 but a Dell Inspiron 5493. It has a wifi controller with the same PCI ID but a different subsystem ID (8086.42a4), and it works fine.
Kernel: 5.4.0-17-generic linux-firmware: 1.186 Will find an XPS 13 and wifi device with same subsystem ID to test. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1859287 Title: iwlwifi broken for Killer Wi-Fi 6 AX1650i with 5.4/20.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1859287/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
