=== Steps to (mostly) prevent this from happening in the future: === * If dual booting, Windows has a "hybrid shutdown" mode that apparently disables WiFi cards sometimes. ** One fix in the future is to: <blockquote>go into Settings > Power & Sleep > Choose what power button does > Shut down setting > uncheck the Turn on fast startup > save change and it will work. </blockquote>Source: https://old.reddit.com/r/pop_os/comments/l2ykc2/no_wifi_adapter_found_intel/gk9bg7s/ * Sometimes, the BIOS does this at random occasions automatically. For example, if I plug in a different USB-C charger and it complains that the chargers are "not Dell chargers" (even though they work), then when rebooting, it will have already gone into "hybrid shutdown" mode. ** Currently I don't know of a fix for preventing this behavior, other than disabling that warning, as well as the "low battery/critical battery/SupportAssist" warnings. ** There may be others I haven't found yet.
