I recently upgraded my computers and network, computers first. The computer in question is an Inspiron M5040 with a DW1503 wireless card I purchased in March or so. I recently upgraded my router to a dual band router, and my computer can't take advantage of the 5ghz band, it won't even see it. What dual band wireless card can I upgrade with that's basically plug and play, pop out the old one, slide in the new one, install the driver and go? Any solution?
