I have an HP Mini 210-1040NR that previously ran Windows 7 Starter. Because of extreme lag I downloaded and installed Ubuntu 14.04.1 and installed from a USB drive made by pendrivelinux. First, I used the demo and installed the driver that came from some source file. It ran nicely and I successfully connected to the internet. I installed Ubuntu, but then the wifi driver vanished. I edited my settings in Software and Updates to match that of the Live Demo's, and the driver appeared. However, when I attempted to install it, I got about 10% through, then it stopped and I eventually had to cancel it.

My Wireless driver is, according to feedback from the

$ lspci -nn -d 14e4
Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)

It would be really helpful if the driver or whatever I need to fix this was downloadable from any OS, because I don't have any access to ethernet. If it's the only way though, I might be able to find a way.

This normally works sudo apt-get purge bcmwl-kernel-source broadcom-sta-common broadcom-sta-dkms and sudo apt-get install firmware-b43-installer and reboot https://www.dropbox.com/s/7exlzch25ap6uha/b43.zip?dl=0

And copy the files to /lib/firmware/b43

  • You should read the question, especially the last paragraph. Feb 12, 2015 at 19:03
  • I used a Mac to download the file, then moved it to a USB, which I plugged in to my Ubuntu machine. Apparently, even though I am the original Administrator of the machine, I don't have sufficient privileges to make edits to the /lib directory.

  • Try sudo mkdir /lib/firmware/b43

  • Using information I collected from elsewhere, I went into root mode and used 'cp -r' to copy the extracted folder of b43 to the '/lib/firmware/b43' directory. Either I put a folder in a folder, or the install command still didn't work.

Well. I installed my original Windows 7 OS on the laptop and created new Ubuntu install media, downloaded from another mirror on the Ubuntu site. Installed it, and boom. Wifi suddenly works. Thanks for trying to help, though!
