I had this netgear WG511T (which is 11g) card in my laptop and it worked great but I today I just got a WN511B (11n) and I uninstalled the old cards software, unplugged it, installed new cards software/firmware, and plugged in the new card and all the settings went with no problem and it saw the network, but I get limited or no connectivity. It says I get 270mpbs right next to it and 100%. The old card worked as soon as I plugged it in what am I missing?
