I've installed the Elementary OS onto my old MacBook Air. I can't get the laptop to recognize and connect to my wifi though. Any suggestions?

Pix... 934 shows that I don't have a regular LAN connection.

Pix...754 shows that none of my Wi-Fi connections are showing up.

Pix... 624 is the new screen that shows up when I select one of my WiFi connections.

Pix... 604 shows all the available Wi-Fi connections.

Pix... 414 shows the screen when I turn the computer on and press & hold the 'Options' button after the computer makes the little music sound.

I read something somewhere about needing to activate the network or something. Any thoughts?

I was hopeful when I saw this 'Options' screen with my WiFi connections. So I tried all of them and still nothing. I think I'm missing something real simple here. Humm...

Appreciate all & any help. Dan

Okay, so I got into the GRUB menu by pressing the 'esc' key within the press hold the 'option' key after you hear the Macbook chime at startup. Here are the lists of items to choose from after typing 'help' at the GRUB menu screen came up. Any suggestions?GRUB menu list 1GRUB menu list 2

  • Hey Dan! What model year (about) is the machine and can you run 'lspci' in a terminal and tell us what it shows for the Network Controller?

  • I think what you'll be looking for is in the link in my previous comment. Your wireless device is the BCM4321, if you didn't already know... Good Luck!!!

Hello try to open directly in the boot process with the esc button Grub. A menu appears to confirm extended processes for eOS and start with the Rev. item. In the menu a sub-item Activate network appears. Run Rev. completely and restart and your network should be activated

  • Thanks user13814 for your suggestion. I'll give it a try. Here's Google's translation BTW. Hello try to open directly in the boot process with the esc button Grub.
