Hi,
Sorry, I've made the very common mistake of assuming a level of knowledge that you have not yet obtained.. my bad!
Basically the Linux kernel detects all hardware at boot time. As the system is initialised and "starts to run", the kernel generates a great deal of (what I call) diagnostic messages.. these typically detail "when" and "what" information about the system startup.
These messages are buffered and can be seen in a terminal with the dmesg command. It's often more useful to redirect the output of this command to a text file for later viewing. You could also post any relevant extracts here.
Use this:
Look for any messages containing the words "fail", "error" or "warning" or "unclaimed" etc.
Just load dmesg.txt into a text editor and search the file.
Here is an extract of the output of dmesg from my laptop:
Code:

Starting at timestamp 5.778180 seconds, you'll see three firmware load fail messages. The kernel is looking for one of three specific firmware files for my Intel wifi card. It cannot find them within the default firmware file locations within the system and reports this..
If your kernel recognises your network hardware, but cannot find the required firmware, then you should see some sort of indication here.
Also, have a look at the output from:
Code:
lspci > lspci.txt
lspci
The first line redirects the command output to a text file. The second just displays it.
My lspci.txt:

The last two lines here show my ethernet and wifi cards.
Does yours show anything similar?
