Right not i have 3/4 wireless devices with 802.11n in my house, and thinking of getting a decent cheap n router and going 100% wireless N. I know about how much better N speeds are compared to G, but am confused on real world speeds. I believe there is a data cap that does not come close to hitting my wireless G speed of 54 MB/s. Would it still be worth it to update from the 54 MB/s to 150 or 300? More generally, what are the best reasons to update? I am totally confused about why you want such a high transfer rate when the upload/download speeds are so low.
