I installed Ubuntu 16.04 LTS on an old MacBook Air that had ceased working (pinwheel of death, OS X wouldn't boot). Wiped OS X from the machine on install. The idea was to get some additional usage out of a machine that otherwise would be headed for the trash. Ubuntu works just fine, and connected to the wifi during install.
On restarting, however, it now says "No network devices are available", and can't see wifi network(s).
Please note that its a Mac and only has USB and Thunderbolt ports–so cannot connect to ethernet.
I'm not very techie, and new to Ubuntu, so any suggestions please be plain and practical. Thanks!
UPDATE:
02:00.0 Network Controller [0280]: Broadcom Corporation BCM43224 802.11a/b/g/n [14e4:4353] (rev 01) Subsystem: Apple Inc. Airport Extreme [106b:00e9] Kernel modules: bcma 03:00.0 PCI Bridge [0604]: Intel Corporation DSL3510 Thunderbolt Port [Cactus Ridge] [8086:1547] (rev 03)
SUGGESTED SOLUTION:
The needed driver bcmwl-kernel-source, is on the installation media.
Please check here: askubuntu.com/questions/835475/…
DIDN'T WORK:
FATAL: Module wl not found in directory lib/modules/4.13.0-26-generic" . Wifi still not working.
FOLLOW-UP
What version is the deb file?
bcmwl-kernel-source_6.30.223.271+bdcom-0ubuntu3_amd64.deb? Note it
should be xx-0ubuntu3. If not, I will un-dupe the question and propose
an answer. – chili555 1 hour ago
RESPONSE:
It appears to be 0ubuntu1~1.1
FURTHER UPDATE:
Did as suggested here:
I suggest that you download this package on some other computer and
put it on a USB key or similar.
http://mirrors.kernel.org/ubuntu/pool/restricted/b/bcmwl/bcmwl-kernel-source_6.30.223.271+bdcom-0ubuntu3_amd64.deb
Transfer it to the Ubuntu computer to some convenient place such as
the desktop. Now, in the terminal:
The "arch" command result was was fine with following result:
x86_64
I then followed the further commends in terminal and got following result:
dpkg: error: dpkg status database is locked by another process
FIXED!
Thanks guys, the last fix suggested worked fine, and my Ubuntubook is now connected to the internet. Good job.
