OUI part of MAC address of the Wifi Lan card can't be found on Wireshark lookup web

Hi,

I try to find the manufacturer of my Inspiron's wireless LAN card by looking up the first 3 bytes of the MAC address on Wireshark website, and it responded that address couldn't be found. However, Windows device manager shows that the driver is working correctly. Could this point to some problem with the card or even the card driver? Thank you
