Is the module (driver) installed? A good way to check would be getting the output of 'lspci' and 'lspci -n'. Using my x200 laptop as an example, lspci will return a line like: ... 00:19.0 Ethernet controller: Intel Corporation 82567LM Gigabit Network Connection (rev 03) ... What is important from this line is the 00:19.0. At this point, we are going to check if the above Ethernet controller is supported. We need to now get the output from 'lspci -n' on the same machine and look at the line with 00:19.0 in it. ... 00:19.0 0200: 8086:10f5 (rev 03) ... The important part here is the 8086:10f5. This is the hardware pci id. We can compare this information to the kernel drivers and 'modinfo'.

You may or may not get the module information. If you do not, that is a good indication the piece of hardware is not supported. You should also search for one part of the hardware pci id to get more results but a good rule of thumb is if you don't get anything back, then you _may_ (not always) need to get the driver from the vendor.
