Often, Ubuntu 21.04 does not find the Wi-Fi driver

Recently, Ubuntu 21.04 began often not to find the Wi-Fi driver on upstart (lshw -c network gives an empty answer). I believe this behaviour was actually first seen with version 20.10. When I turn power off and then on again, the operating system often succeeds the second time. Sometimes more than one such turning off and on is required. Once I went into the BIOS and turned LAN first off and then on again. That made the operating system recognise the Wi-Fi driver for that session but not permanently. Does anyone here have a similar experience and know a remedy? The Laptop is Dell XPS 13 7390, and lshw -c network describes the hardware as follows.

just install synaptic manager and searc for your driver and download it

Supplement: When the operating system has not found the Wi-Fi driver, it also typically halts at shut down so that I must do a hard break to turn of the laptop. The screen is just empty with a cursor in the upper left corner. After I have pressed the hard break button, the screen sometimes displays a few lines, apparently about failing contact to periferal units such as a mouse. This text diappears so quickly that there is not sufficient time to read all of it. I have not yet seen any useful proposal of a remedy.

Canonical seems to have fixed the bug in recent updates.

No! Just after the above was written, the WiFi-driver was again missing after the laptop was turned on. It then cropped up after shutdown and a new start.

The problem did not arise after I upgraded to 21.10.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
