B450M/AC No Lan Card detected

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I bought a B450M/AC motherboard.  When I plug an known working ethernet cable into the connector in the back, nothing happens.  It does not show a Lan card in Device Manager,  all it shows it Bluetooth and WLAN.  I've tried installing the Realtek Lan Drivers, but it's telling me that no Realtek chipset has been detected.  I've checked in the BIOS, but I cannot find anywhere to enable onboard LAN.

Any help would be appreciated.

Thanks
