Thanks. The iwconfig output seems to show the wifi adapter is missing at the kernel level. When it was working your kernel log shows the adapter was called 'wlp1s0'... Next time the problem happens, please run this while it is happening:
dmesg > dmesg.txt and attach the resulting text file here. ** Also affects: linux (Ubuntu) Importance: Undecided Status: New ** Also affects: linux-firmware (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1915491 Title: Dell Latitude E7470 wifi adapter (Intel Corporation Wireless 8260 [8086:24f3]) installed but can't be found in Settings To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1915491/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
