Siva Ram

i use Ubuntu 20.04. Recently the kernel version got updated, Not sure because of that or not, the wifi was unstable for few days and now it is not working at all. it says no wifi adapter found.

this is what i see from dmesg. This is with kernel 5.4.0-91

dmesg | grep wifi

Kernel 5.15 is not a Ubuntu supported kernel; so if your system updated to it, it wasn't from Ubuntu *stable* repositories (at best a *testing* kernel added by someone with `sudo` rights on your box). Testing kernels are for that purpose - testing. Use the *stable* 5.4 (GA) or 5.11 (HWE for 20.04.3, 5.13 for 20.04.4) kernels.

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.
