I have an old hardware x86 PC running 12.04.5. I had been ignoring the Update Manager and using the CLI for updates till recently when I decided to use Update Manager, BIG MISTAKE!!!! It hung my system and when I was able to reboot I had lost WiFi, all my printer setups, and more. Recovery mode did not help. I tried loading a driver for a Realtek 8192 dongle but the shell failed because the Manager had left the Modules incompatible with installed Essentials and Headers. I have been booting to the “Previous Version” from GRUB 2 (which has internet access). I want to remove the updated version from my system since I have no trust in what the Manager did. I would like to install the newer kernel and keep the presently working version as backup. Currently: kernel 3.2.0-126-generic-pae is GRUB 0, which is the bad version, no internet etc kernel 3.2-0-98-generic-pae is GRUB 2 which I can boot into to get internet access. Windows XP Professional is GRUB 5 which I need for the SCSI access, not an issue here
lsb_release -a yields the following No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 12.04.5 LTS Release: 12.04 Codename: precise

I am not sure how the x86 versus the 64bit issue is affecting me. I only want a working system that can be updated to a known state. I would like to clean up the 3.2.0-126 so it can boot and not lose wifi. ("sudo apt-get update" did not do the job)
Any suggestions would be welcome.
(P.S) The old hardware has PCI cards for SCSI scanner access so I want to keep it but I tried 14.04 LTS once and it had graphics issues. Not my only PC so old versions of Ubuntu are fine.
