In the case of Wireless N Vs. G, it is a total knockout! I have just changed the wireless card on my laptop from G to N and the difference is like night and day.
The range is much better. I am as happy as a giddy schoolgirl!
The N also picks up the other freqs' so it is well worth the upgrade. At a cost of $89.00 it is a very good buy.
The Blue card Linksys is the N card.
