Am operating Ubuntu OS version 14.04 LTS on my Dell Inspiron 15 and it was working fine up until a security download update yesterday. I was told to reboot after the download but when I did, it immediately cut off my home wifi connection network and still won't connect unless I connect direct to my modem with Ethernet cable.

I know what the problem is because I managed to get into my grub boot loader menu and can reboot wireless without cable to make the connection and gain access to the internet. But once I shut down and reboot it uses the latest new kernel in the menu once again and won't connect. Then I again have to go back into boot loader menu again and manually reboot with the previous kernel recovery mode program.

I need to remove latest downloaded kernel so it will once again boot up and connect automatically like in the past but I don't have enough experience with root terminal commands and procedures.

Can anyone confirm a sure and fast solution that is the easiest because I'm not a very exp root terminal guru with commands?
