reinstall 11.10 without a cable connection and getting the wireless to work

[G.]

I wish to do a clean install of 11.04.  I do not have a cable
connection.  How can I install the drivers for my Broadcom BCM4313
802.11b/g/n Wireless LAN Controller without a wired connection?  I
assume that the wireless connnection will not work once I reinstall.
I can connect with the wireless using a live CD however and have
installed the drivers once the live CD booted.

Thanks
