Update old Compaq to linux..?

[fred]

Hi Wirezfree thanks for the reply,We originally had the computer connected to the router by cable and that worked well, however this  time it would be nice if we could add a wireless card.  I haven't done anything like this before, with regards to the Asus I listed earlier, do you know if this is a simple task in LL or is there perhaps a better/more LL compatible option?
