I just got a new Dell Studio 1537 which happens to be equiped with an Intel 5100 b/g/n wireless card.  I am able to see more networks then before and my own network is stronger, but I am still only connecting at 54 mbs.  When I go into Device Manager, it shows N settings for my card and says that it is an N card.  However when changing my home router to N only it lost my connection.  It can see the network and see that it's a N network and list the correct SSID and security type, but it will not connect.  Anyone else have a problem with this or know what to do to resolve it?
