OK - complete newbie alert (ie me)

all of this below assumes that one already has some other alternate working connection to the internet. currently my computer with ubuntu is far away from the router and hardline connection to internet (hence the need for the WNDA 3100 wireless dongle.
I have ubuntu sitting on a usb stick and am using an old computer (think windows xp vintage) booting from the USB

can I connect to my new windows 8 computer via a ethernet cable and share internet to complete these steps? or do I need to run a hard line all the way to my router?

I tried to use the windows 8 computer and boot from a USB stick - but that does not seem to be working.

assistance appreciated.


[QUOTE=Green_Bean;8680365]Well after days of combing the internet and beating my head against the wall, I finally got my Netgear WNDA 3100 v2 wireless adapter working on my old Dell PC running Ubuntu 9.10 (Karmic Koala).

I am not highly technical, and am fairly new to linux, so this was a real challenge for me, so this is a kind of "Wireless for Dummies".

I will try to describe step by step for those other frustrated n00bs out there who are struggling with this.

First I installed the firmware by typing into terminal:

sudo su #
cd /tmp
wget http://launchpadlibrarian.net/27826554/ar9170-1.fw
wget http://launchpadlibrarian.net/27826554/ar9170-1.fw
mv ar*.fw /lib/firmware
