Macbook Air 2015 wifi adapter not found issue

lk flag

What happened:

  • Wifi stopped working.
  • 'Wifi' tab inside settings says 'no wifi adapter found'.
  • Reboot does not help.

Diagnostics:

lspci shows:

03:00.0 Network controller [0280]: Broadcom Inc. and subsidiaries BCM4360 802.11ac Wireless Network Adapter [14e4:43a0] (rev 03)
    Subsystem: Apple Inc. BCM4360 802.11ac Wireless Network Adapter [106b:0117]
    Kernel modules: bcma

so the adapter is still there -- likely a driver issue.

Solution:

apt list --upgradeable shows:

  • bcmwl-kernel-source

as a package not in latest version.

Running sudo apt install bcmwl-kernel-source fixed the issue.

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.
