Just found out that my wireless card in my XPS 17 can't do 5 Ghz. I only have a 2.4 Ghz single band wireless n router. Now I am not going to waste my money buying a dual band router. This is why 2.4 Ghz sucks for wifi and should have never been the standard. It is overcrowded because of only three non overlapping channels and 95% of the wifi devices only do 2.4 Ghz. It does not matter much since I use Ethernet on any of my devices that support it. My laptop, PS3 etc. I only use cruddy wifi for devices that don't have Ethernet like my iPod Touch.
