So you mean you have a laptop, connecting via wireless, then you try pinging this RFID reader which only supports 10Mbps.
You see first if there is LED light at the switchport physically. Seem the switch does not support 10 Mbps anymore, so it is 'the device fault'. Ask the vendor to change to more recent device.
