wifi card not being detected at all on my laptop

ao flag

Just a few days ago, the wifi on my laptop was working just fine. It has went from working just fine, to working every 3 or 4 times I turn the computer on, to not working at all. The wifi switch is on, but the wifi does not turn on at all. All the drivers, including the non-free ones, are installed. I have checked lspci. It didn't show up in the list of devices. I have also checked sudo lshw -C network. Only the ethernet hardware showed up. I have tried rfkill list all, but it gave me nothing. Then I tried rfkill unblock all, but nothing showed up either, and it still wasn't working.

Specs:

  • Sony Vaio VPCEB35FX

  • Intel Core i3

  • Intel Centrino Wireless Card

  • Xubuntu 22.04

A recent change with 22.04 was the move from 5.15 (GA) to 5.19 (HWE) if using the HWE kernel stack; I'd try selecting an older kernel (5.15) at grub and see if the issue still occurs... ie switching from the HWE kernel stack to GA maybe an easy option. With Xubuntu, your installation ISO dictates which kernel stack (GA or HWE) you're using by default (*though it can be changed post-install & both kernel stacks can co-exist unless using certain nvidia kernel modules*)

You might want to physically remove the card from the motherboard and reinsert it, if that doesn't work, it might have failed internally

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.
