Is anything stored on an AirPort Extreme card?
I have what might be a dumb question. My old Airport Extreme (the white UFO type one) bit the dust, but the AirPort Extreme Card inside is still OK (A1026) . I saw that there are folks on Ebay who'd want it, so I figure I'll just sell it. So here's my dumb question: Is anything stored on that card? Any info about my WiFi network, etc?
MacBook Pro (15-inch Late 2008), OS X Yosemite (10.10.4)
