Sometimes I wander if the Wi-Fi certification does any good at all.
I have never seen any notebooks equipped with Intel Wireless come with Wi-Fi certification(s). and at the same time, I have had the most wirelss problems with Intel Wireless modules.
It seems that Intel dont really care about WI-FI at all. Maybe the Wi-Fi certification isnt even worth while.
well erm, check the wifi alliances page, intel has several certified adapters.
anyhow, erm, i'm making my own and first wireless network at home. I'm going with A. While your all hogging up the 2.4ghz spectrum, I'll be enjoying crystal clear, interference free 5ghz frequency
