I got the Killer Wireless-N 1103 network adapter for my M14x and I haven't really used wireless since I've have an Ethernet cable. But I do plan on using it wirelessly when I'm not at home and I noticed that the card is disabled by default. I enabled it but it didn't seem to have any effect at all. The Killer Network Manager isn't registering that the device is enabled and it isn't picking up an internet connection. Dell and Bigfoot are no help at all. The driver version is 220.127.116.11 which I think is a higher driver version than you can download from either Dell or Bigfoot. I don't know what to do in order to get it to work.
