|so i found our old wireless adapter. installed it all and it found the wireless connection from my main pc. |
This sounds like some kind of ad-hoc setup and I'm not sure you can make it work. I suspect that in order for it to work, you'd have to enable ICS on the computer's wireless adapter and I'm not sure you can do that. Besides, there is an easier way.
Go buy a wireless SOHO router and use that. If you already own a router that isn't wireless capable, buy a wireless Access Point.
