Hi, which distribution of linux are u using

What brand of card is it, and what chipset is it using? It may not be 100% supported by Linux. If you can post the output of lspci it may help as well

hello,
i think you can do it like this
ifconfig hw <HW> <address> - where
<HW> is the hardware type (most likely ether)
and addess is the MAC address.

As PBHARRIS said, to change your MAC address use "ifconfig eth0 hw ether ne:wM:AC:add:re:ss" (change eth0 to whatever adapter you want to change, usually with only 1 adapter in your machine eth0 is the name of it),but I prefer to find out why the NIC isn't reporting the correct MAC address in the first place. If the Linux isn't getting the proper MAC address odds on there is some underlying problem there stopping Linux from setting the correct address up on the adapter thus stopping the network from assigning an ip address to your machine (if you are running DHCP on your network). The NIC also may be faulty, have you tried an alternative NIC?
