I was reading the manpages of athn/iwn for purchasing a suitable wireless card and found repeated occurences of 2GHz, when in fact it should be 2.4GHz. That is the standard frequency when purchasing a wireless a/b/g/n card. The code is filled with 2GHz references but just changed to man pages in section 4.
