It's a laptop. You can use a wired connection to paste the text as an update. You can copy the text and paste as an update

udo: ishw: command not found
No command 'isb_release' found, did you mean:
 Command 'lsb_release' from package 'lsb-release' (main)

Thanks for the time and effort. I am not pc savvy enough to do this every time there is an up.date. Is it possible when an install is working ok to just update the security part of the update without turning off the wifi.

OK if i reinstall ubuntu 14.04 from usb that wifi works on am I safe security wise to ignore all upates?

I will continue to buy wifi adaptors as needed

i just have to respond. you guys with linux do a great job providing a free system to the old xp users for example to keep them connected. About every pc I installed linux in every form from puppy to ubuntu I donated to a low income senior center To get a response like upgrade away is kind of disgusting to say the least.
Thanks for all your help
