One would have to test both but my bet the result would be the same as before. Depending on the location, router and time of day, one will win over the other.
Since they are fairly equal I wonder if you know why they offer the choice?
Lenovo offers two "free" wifi options:
802.11b/g/n Wi-Fi, and
Intel Centrino Wireless -N-1000.
Which is better?: 1] for distance {outdoor} 2] speed, etc.
They also offer, $55, Advanced-N+WiMax 6250. Is it worth it? I currently do not have a smart phone.
