 Candelatech also has a [http://www.candelatech.com/ath10k-10.4.php web page] for custom firmware files that may be required for certain radio's such as the [https://www.compex.com.sg/product/wle1216v5-20/ WLE1216V5-20 wave 2 radio].
 
+You may need this firmware if the ath10k driver and QCAXXXX firmware combination does not properly probe your device and create an interface. This would appear in your system log as: 
+{{{

+[    2.362540] ath10k_pci 0000:02:00.0: failed to fetch board file: -2
+[    2.362541] ath10k_pci 0000:02:00.0: could not fetch firmware files (-2)
+[    2.362543] ath10k_pci 0000:02:00.0: could not probe fw (-2)
+}}}

+If this is the case, execute these commands to retrieve new firmware and replace the defaults.

+{{{#!bash
+# Download Candelatech's firmware.bin and board.bin files
+wget http://www.candelatech.com/downloads/ath10k-9984-10-4/board-2-ct.bin
+wget http://www.candelatech.com/downloads/ath10k-9984-10-4/firmware-5-ct-full-community.bin

+Note that this example was done for the [https://www.compex.com.sg/product/wle1216v5-20/ WLE1216V5-20 wave 2 radio] using a {{{QCA9984}}} chipset. You may need to change your {{{wget}}} and {{{/usr/lib/firmware/...}}} targets accordingly.
