I did a server dist-upgrade from 12.04 to 14.04LTS, and in the process, lost all networking. I'm open to either getting the existing drivers loaded and working, or seeing if a dist-upgrade to 16.04 (possible from DVD?) would fix things. More interested in getting my ethernet working, but including wifi for completeness.

I've tried a bunch of suggestions, but right now, both eth0 and wlan0, after an lshw report sudo: unable to resolve host ubuntu... *-network UNCLAIMED

My ether is Qualcom Atheros - AR8132 Fast Ethernet

My wifi is Broadcom - BCM4312 802.11b/g LP-PHY

In /lib/firmware/br* there are a bunch of bin files, but there's no /lib/firmware/ar8* directory, but there are a bunch of other 'ar#' directories.

Definitely a noob with this, so any help would be appreciated.

Thanks

Here are the added lshw results:

*-network UNCLAIMED description: Network controller product: BCM4312 802.11b/g LP-PHY vendor: Broadcom Corporation physical id: 0 bus info: pci@0000:01:00.0 version: 01 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list configuration: latency=0 resources: memory:feafc000-feafffff *-network UNCLAIMED description: Ethernet controller product: AR8132 Fast Ethernet vendor: Qualcomm Atheros physical id: 0 bus info: pci@0000:02:00.0 version: c0 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress vpd bus_master cap_list configuration: latency=0 resources: memory:febc0000-febfffff ioport:ec80(size=128)

uname -a gives:

Install this package

http://mirrors.kernel.org/ubuntu/pool/main/l/linux/linux-image-extra-3.13.0-113-generic_3.13.0-113.160_i386.deb

Most likely it is not installed. It contains almost all hardware drivers.

You may also need to install

http://mirrors.kernel.org/ubuntu/pool/main/l/linux/linux-headers-generic-3.13.0-113-generic_3.13.0-113.160_i386.deb

http://mirrors.kernel.org/ubuntu/pool/main/l/linux/linux-headers-3.13.0-113-generic_3.13.0-113.160_i386.deb

I was never able to get the linux-image-extra-3.13.0-113-generic_3.13.0-113.160_i386.deb on its own, or any of the many drivers suggested in other threads, but by going to https://ubuntuupdates.org, and backtracking through the errors of what was missing, I searched the missing items, and kept trying installs, until one finally went through without errors. With sudo dpkg -i *.deb, I installed in this order, which might vary for you, or you may require additional/fewer installs, and may not make any sense to the more experienced, but worked for me:

linux-headers-3.13.0-129_3.13.0-129.178_all.deb
linux-headers-3.13.0-129-generic_3.13.0-129.178_i386.deb
linux-headers-generic_3.13.0.129.138_i386.deb

rebooted and saw it listed that "limited" (???) networking was back. I tried, and was able to run sudo apt-get update && sudo apt-get upgrade which took just under a full hour, had to fix a lot of config's and settings with PHP and apache, after manually re-installing them, because they were held back in the update/upgrade, but I'm back up in a basic capacity now.

Thanks for all of the patience and leads. Hope this helps someone else.

P.S. While I went from 12.04 to 14.04, because of a change with PHP, this post was helpful in getting apache back up, even though it addresses 13.10: Upgraded to Ubuntu 13.10 - Apache not able to start
