Broadcom without internet

[Sin@Sin-Sacrifice]

I have no interweb on my old hard drive because it was hard wired in its previous box but now I need the broadcom drivers for linksys' wmp300n wireless adapter. Could I just use the installed broadcom drivers from ubuntu on another partition or do I have to reboot every time I find I need something from the internet? Again... I have no internet connection on that partition at all and want to avoid rebooting for every dependency. please and thank you. :)
