With Wireless N you have the option of using either 20- or 40MHz-wide channels, whereas Wireless G supports only 20MHz. The larger channel footprint, in effect, makes it possible to achieve higher throughput or transfer speeds.

To help reduce the possible interference to Wireless G networks caused by using such larger channels, Wireless N products are shipped with the smaller channel-width set by default.

Thus if you want to get the highest speeds for transferring files between your newly equipped computers, you need to change this setting on your router. Check in the basic wireless settings area of the web-based utility.
