Dual Wifi Compex Card

Hi!

Some time ago I have bought Mikrotik routerboard RBM33B.
In one of the slots I wanted to have both 2,4 and 5GHz interfaces supported.
I bought Compex WLE600VX card (revision? 7AA) and installed in second PCIe slot. From what I understand, I should have both interfaces available in Mikrotik WinBox GUI.
The cards (as far as I understood searching internet) should work with this routerboard. Checking this post: http://forum.mikrotik.com/t/compex-wle600vx-minipcie-on-rb912uag-2hpnd/79445/1
it should work fine.

However, it looks like is incorrectly detected, and I have only one interface (in section "wireless) where I can setup either 2,4 or 5 GHz interface. There is no second interface available.
In addition, this board is in WinBox detected as Atheros AR9888, where the manufacturer says it is a Atheros QCA 9882 chip installed.
When I check the system resources, under PCI tab the board is identified as: Atheros Communication, Unknown device (rev: 0), vendor 0x168c, device 0x003c.

So maybe this is some problem with detection of the board?

Do you have maybe any suggestions about the card?

Thank you! Best regards

The detection is right, so, the chip itself is dual band (Not 2 chipsets for each band).

Some chipsets that are dual band let use both bands at same time and others only one at same time.

Regards.
