This is a dual band router. What this means is that there are 2 WIFI signals being broadcast. 2.4 and 5.0 ghz. The 2.4 is the "older" wifi. Most newer products have the 5.0 ghz and this allows higher speeds, however the signal doesn't travel as far as 2.4ghz. The 5.0 works best for speeds above 24mbps service, since the 2.4 is usually capped at that speed.
