Just received a new 660 computer. It has a DW 1506 wireless card. The card connects to 2.4 GHz only. It does not connect to 5 GHZ. Dell tech says that it only connects to 2.4. The info when ordering does not include that in the description. I had to go out and buy a 5 MGz adapter. Anyone else have an issue like this? If so, did Dell do anything to resolve it? Thanks
