Kernel 3.13 is quite old; however according to 
https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi#firmware, the driver 
for the 2230 has been in the kernel since version 3.2. That reference also tells 
you what firmware is needed.

To resolve this, first check that the driver is available. If the command 
"modinfo iwlwifi" returns an ERROR, then your kernel configuration does not 
contain the driver. You will also need iwldvm to be configured.
