D-Link DWL-520+ won't connect to router

Using openSuSE 11.4
D-Link DWL-520+ won’t connect to my router.
The computer recognises the wireless card is there and working but I can’t get it to connect to the router. Not sure how to get it to connect.

Seems like this is a pretty old chipset. I suggest you look at the following page for help:

The ACX100/ACX111/TNETW1450 wireless network driver project (Linux, BSD)

Thank You,
