Ok I have the Dlink Rangebooster N router and notebook card from Newegg recently. I have the router up and running perfectly. I have a laptop with internal wireless connecting at 270 but I have another desktop I built using a Rosewill PCMCIA adapter to use the N notebook adapter on the new computer. Problem is that the new computer is only connecting at 54 which is G speeds. Is there some sort of setting on the notebook card somewhere that tells it to use g or n? Right now the router is using WPA-TPIK (pardon if wrong arrangement of letters) and is mixed g and n. I set it to N only and the new desktop will not even recognize the router so something is up with the notebook adapter or maybe the PCMCIA adapter will only allow g speeds.
