difference between NM-AIR-WLC6 to NM-AIR-WLC6-K9 CARD

Hi Guys

This may be a silly question but I have been having some challanges regarding getting my NM-AIR_WLC6 module to work on my 2811.

I noticed the part number is NM-AIR-WLC6 which is the old cards but will software wise be different from that of the NM-AIR-WLC-K9

This is the second wireless module which i have replaced since the first one gave the same errros but i think this is a software problem since when i loaded the code ,i cannot verify the code but the box runs and detects all.

Strange problem

Kindly  look at status and specs from router
