14.04 - How do I enable ethernet, after a failed server dist upgrade to 14.04LTS?



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:

uname -a gives:



Linux ubuntu 3.13.0.113-generic #160-Ubuntu SMP Thu Mar 9 09:28:25 UTC 2017 i686 i686 i686 GNU/Linux



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
