I'm thinking about buying a Netgear Model WPN824 wireless router in an attempt to eliminate some dead spots in my home. Will the MIMO technology of the WPN824 work with older 802.11b equipment (SMC 2602W, Orinico Gold, HP ZE5375 laptop) to provide better coverage? Or will I need to put newer RangeMax MIMO cards in the remote computers to see any benefits? I currently have a Linksys BEFW11S4 with the larger antennas.
