The problem also affects the "airplane mode". The loss of wifi connectivity can be restored by entering and exiting airplane mode provides the option to reenable the wifi board. Additionally, using the fn+ key combination airplane mode can be manually entered, but not exited. (which seems to be a common 18.04 problem, with a simple web search).
I have just updated to the latest Dell firmware version for this device with no improvement. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1788073 Title: Wifi adapter not found after suspend (iwlwifi) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1788073/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
