Ettercap and ARP poisoning / DNS Spoofing... not working?

[MR2Quick]

I have been trying to setup an ARP poison attack on my roommates computer using Ettercap. I follow the directions found HERE but it never seems to work.

EX: when he visits a page that i remapped in the /usr/share/ettercap/etter.dns file it still will not redirect the DNS to the specified IP even though the "chk_poison" plugin says its a success.

Any ideas? could it be my wireless card? Intel 4765ABGN (i think thats the numbers) any and all help is greatly appreciated.
