wlan interface not visible

Hello,
i just installed some old wifi card into my RB411U.
It seems that the card gets recognized

[admin@MikroTik] > system resource pci print   
 # DEVICE   VENDOR                                 NAME                                       IRQ
 0 00:12.0  Intersil Corporation                   ISL3890 [Prism GT/Prism Duette]/...         48

but no wlan inteface is visible…

Just because ROS knows gadget’s name it doesn’t mean it’s got drivers for it.

are there any installable driver packages or something like that?

No.
